Specifications of shortwave radios from various manufacturers
Last updated June 6, 2006
The information below was compiled during my (so far unsuccessful)
search for the ideal shortwave radio to replace my old Sony ICF-2010.
I discovered that there was so much information to digest, the only
way to organize it was to put it on a Web page. Much of this information
has been pasted directly from the vendors' Websites and may or may not be
factually correct. Where the information is known to be incorrect or
misleading, this is noted. Most of the opinions are my own, based
mostly on the publicly available specifications and comments from
various Internet sources.
The information describes the specifications of receivers that I have
not tested, and summarizes the opinions that seem to be generally held
about each receiver based on comments I found on the Internet. I have
not personally verified any of this information.
In case you're interested, I decided not to buy any of the
radios listed here, but repaired my old Sony instead.
Receivers
Software-defined radios>
The number of software defined receivers is exploding.
This is an incomplete list of a few popular SDRs, not necessarily
the most capable or flexible ones. Many of these are nothing more
than computer boards, and considerable expertise is needed to install
and use the product. Others, like the Winradio, are more consumer-friendly.
See

more information.
Antennas
An incomplete list of some active antennas.
Drake R8B

AOR AR5000
AOR AR5000
$2599
Goes down to 100kHz (or 10 kHz for the AR5000A). Good sensitivity.
Very expensive. Also handles TV signals (TV demodulator is $200 extra)
The new AR5000"A" models cover all the way from 10 kHz to 3 GHz
(less cellular on blocked models),
Modes of reception include: AM, FM-N, FM-W, LSB, USB and CW. Six
bandwidths are supplied (3, 6, 15, 30, 110 and 220 kHz.) and a slot
for a 0.5 kHz filter is available. The triple conversion circuit and
varactor tuned front-end provide excellent overload characteristics.
Two thousand memories in 20 banks of 100 are featured. Each memory
channel may hold: frequency, mode, band width, LPF, HPF,
de-emphasis, tuning step, step-adjust, frequency off-set, AGC,
attenuator, CTCSS tone, antenna selection, 8 character text tag and
lockout! Sophisticated scanning is available including channel pass,
select scan and auto-store. Besides normal scanning (25 memories per
second), there is also CyberScan (45 seconds) without channel tags.
Scanning search (sometimes called sweep or spectrum scan) is also
supported, allowing the radio to automatically tune between
user-defined frequencies. The large front panel is very comfortable
to use. Other features include: two antenna inputs (N and SO-239),
antenna attenuator, keypad entry, computer control, audio filter,
dial torque adjustment, mute, AGC, lock, RS232 port, squelch, analog
S-meter, preamp, removable feet raisers, scanning (25/50
channels/second) and sweep. In FM mode the AGC may be set to Off or
On. In other modes the AGC may be set to Off, Fast, Middle or Slow.
This radio may be run from 12 VDC at 1 Amp (with optional DC3000
power cord) or via supplied 110 VAC adapter. There is a programmable
10.7 MHz IF output on the back to drive the optional SDU5600. There
is also a programmable 10 MHz External Frequency Standard input jack
[BNC] for laboratory applications. Click here to view Quick Ref Card
in PDF format. Installation of one or more filters is $25.00 per
filter at time of receiver purchase.
The "+3" version offers even more with synchronous AM, AFC and Noise
Blanker. Popular with government agencies throughout the world. The
AR5000+3 is a 'feature loaded' version of the AR5000 receiver with
three enhanced options fitted, these options can only be fitted in the
factory during manufacture or AOR workshop:
Synchronous AM
Automatic Frequency Control
Noise blanker
1. Synchronous AM:
Synchronous AM is a useful tool to help reduce distortion due to
selective fading, in particular on the short wave bands (long & medium
wave bands too). In synchronous AM, the original carrier is phase
locked to a stable internally generated synthetic reference which is
used to replace the (variable) original carrier resulting in more
stable reception with greater recovered audio, especially during deep
fades. A wide lock rage is provided by this detector to enable simple,
quick & efficient operation (unlike some other synchronous units on the
market which require extremely accurate tuning).
SAM Synchronous AM double side band
SAL Synchronous AM lower side band
SAH Synchronous AM upper (higher) side band
AM transmissions are constructed of a carrier and both upper & lower
sidebands. Usually both side bands carry the same information so both
or either may be selected with the same recovered resulting audio,
however when adjacent interference is present, selecting synchronous
single side band (SAL or SAH) can provide improved results.
2. Automatic Frequency Control (A.F.C.): Automatic frequency control is
a 'global' facility, either OFF or ON (default is off). When A.F.C. is
used in AM, FM and synchronous AM modes, the receiver is automatically
tuned on to the centre frequency to provide the best signal strength
and recovered audio. When used in synchronous AM modes, A.F.C. ensures
that the signal is pulled within lock range for no-fuss operation.
A.F.C. is particularly useful on the VHF-UHF bands to ensure that the
AR5000 is receiving spot on frequency, especially when searching
through unusual band plans or when the exact band plan is not known.
3. Noise blanker: The noise blanker is another a 'global' facility,
either OFF or ON (default is off). This facility is particularly useful
to help reduce impulse noise and interference from vehicles ignition
systems, whether from passing traffic or while the AR5000 is fitted
into a mobile installation.

This is an AR5000+3 with a spectrum analyzer and a speaker
stuck to it, in a rack mount.
AOR SR1050
AOR has built a package designed to meet the needs of the surveillance
professional. Covering 10 KHz to 2600 MHz, the SR1050/SR1050V combines a
state of the art receiver with an LCD Spectrum display unit, giving the
operator unsurpassed capabilities to identify and a monitor a specific
signal and identify its characteristics.
The "heart" of the AOR SR1050 is the AR5000Plus3 high-performance
wide-band all-mode receiver. With accurate tuning of 1 Hz, analog signal
strength meter and a host of operator-selected features and options, its
performance is highly respected by law enforcement, military and
laboratory users. Teamed with the SDU5500 Spectrum Display Unit, the
package is interactive and computer compatible. The AS5000 automatics
antenna switch (included) works interactively with the AR5000Plus3,
providing automatic selection among four antennas for maximum receiver
sensitivity.
The SR1050V can be used as a vector analyzer, for use in monitoring
digital communications. Data packets in PDC, PHS and GSM formats can be
displayed and identified in binary. It is also possible to see HEX
information at a point from which analysis can begin. PDC, PHS and GSM
can be viewed from the pre-set mode. A manual mode is also available to
change modulation modes and symbol rates. This can be useful in using
other applications, such as analyzing modems. The display can depict eye

Ten-Tec RX-350D
Has LCD spectrum display, 34 selectable IF bandwidths, DSP.
Has 12 KHz IF output for connecting to DRM decoder. Tunable to
1 Hz resolution.
Insides are identical to RX-350 except for DRM output.
$1199 Frequency range 100 kHz to 30 MHz
The new Ten-Tec RX-350D brings you the world of IF level digital signal
processing in a powerful desktop SWL receiver unlike anything that has come
before it. What benefit does IF-DSP provide the shortwave listener? Cleaner
signal readability. Plus DSP can eliminate heterodynes and limit spurious
broadband noise instantly by pushing buttons. Take advantage of the wide
variety of DSP filter choices built-in to the receiver to suppress undesired
adjacent interference. Use these same filters to tailor the response of the
receiver to your needs - from a wide 8 kHz for pleasing SAM or AM audio to a
tiny 300 Hz for digging weak CW and digital mode signals out of the noise.
There are 34 of them built-in. That's right, 34, not 2 or 3 built-in, and not
sold as expensive options!
IF-DSP also allows Flash ROM updating of your receiver with the latest
features and functions. Free! If new functions and features are added to the
RX-350, simply visit the Ten-Tec update website, download the latest version
of the receiver, connect it via a serial port cable to your RX-350 and it's as
if your radio rolled off the assembly line minutes earlier.
The RX-350D features a clean, modern look featuring a large multi-function LCD
graphics panel for display of all receiver functions. Push-button operation of
major receiver controls are provided from the receiver front panel. Simple,
logical layout of front panel controls allow operation of the radio without
having to constantly refer to the instruction manual. Never has such a
powerful receiver been so easy to operate.
RX-350D, covering 100 kHz to 30 MHz, supports operating modes tailored to the
dedicated shortwave listener. Selectable sideband, synchronous AM detection
allows higher quality reception of AM signals especially under conditions of
severe fading. DSP automatic notch filter for suppressing unwanted carriers in
voice modes. Push-button DSP noise reduction to suppress unwanted broadband
noise. The built-in 34 bandwidth filters from 300 Hz to 8 kHz are instantly
selectable by turning a knob. All filters are independent of mode - use any
available filter in any receive mode. Mode selection via dedicated push
buttons rather than 'mode-cycling' with a single control. 'FAST UP' and 'FAST
DOWN' buttons for quick large-step frequency changing. FAST UP and FAST DOWN
buttons are user-configurable for step sizes, 1 MHz, 500 kHz, 100 kHz up or
down. Main tuning knob can be adjusted in 7 user-selectable step sizes from 1
Hz to 100 kHz steps. Passband tuning and automatic notch are available in all
modes, including synchronous AM.
Momentary 'SWEEP' function shows band activity in 8 selectable coverage rates.
Find the signals without even being on frequency! Simply tune to a desired
frequency, select one of 8 SWEEP ranges, and press the SWEEP button. Signals
will be shown on the bar graph on opposite sides of the starting frequency. A
cursor will appear and allow you to tune RX-350 to any signal visible on the
screen. Easy!
The 1024 memories (in 8 banks of 128 channels each) retain frequency, mode and
bandwidth information. Memories are grouped into several banks for easy
storage of frequencies from different bands. An alphanumeric tag function of
up to 8 letters allows memories to be tagged with specific names like "WSEV
930" or "VOA", etc.
Scan functions allow scanning of band segments or memory banks. Memory bank
scan feature includes a memory lockout function for skipping of constantly
busy channels. Band scanning is user-programmable; set the start and stop
frequencies, push a button and the radio starts to scan between the two
frequencies.
Built in clock displayed on LCD screen displays hours, minutes, and seconds in
user-selectable 12 or 24 hour format. Timer circuitry and a squelch-activated
output allow for monitoring and/or taping of band activity even when the user
is not present. Timer function allows the radio to be set in a 'wait' mode, to
power on at a specific time and to send a control signal for actuation of
accessory equipment. Two separate timer outputs are provided for connection of
two separate devices to be actuated by the timer circuit. The
squelch-activated output allows the radio to be left on and squelched on a
given frequency. When a signal is present to open the squelch, an actuation
signal is sent via a rear-panel jack.
Rear panel Hi-Z and Lo-Z antenna inputs allow connection of virtually any
antenna to the RX-350. Built-in AC switching power supply allows operation of
RX-350 from either 115 or 230 VAC. Separate DC power input jack can be used
for 13.8 VDC operation. AC and DC supply can be connected at the same time for
back-up. Plug the RX-350 into the wall and connect to battery supply. If the
AC power goes off, the connected DC source automatically takes over power to
the receiver. Mute function for muting of receiver if used with a companion
transmitter. 12.125x5x13 inches.
An optional remote encoder knob/keypad, model 302, is available for armchair
operation of the RX-350. Simply plug the 302 into the rear panel of the RX-350
via the provided 6 foot cable. The 302 provides a duplicate of the main tuning
knob of the receiver, a direct frequency entry keypad, and three functions
buttons that can be user-assigned to control various receiver functions like
mode switching, main tuning knob step size, SWEEP actuation, etc. Main tuning
knob on the receiver front panel and all other receiver functions are active
even when the 302 is in use. Sit back and relax!
No other shortwave receiver packs this much value 'under the hood'. To top it
off, it's MADE IN USA and competitively priced! Put the RX-350 side-by-side
with your present HF receiver and see for yourself why Ten-Tec is the fastest
growing name in high-quality shortwave receivers. One year limited warranty.

KAITO WRX-911 WORLD RECEIVER
$24.95
From vendor's website:
This beautiful worldband AM FM SHORTWAVE radio is very sensitive to weak
signals so therefore it has excellent reception and it also has pleasant crisp
audio.
The dimensions are 4 1/2 x 3 x 1" so it fits comfortably in your hand or in
your shirt pocket. It weighs less than 8 ounces with two AA alkaline batteries
installed (not included).
Some of the other notable qualities of this great little radio is the inclusion
of a hand strap, a rear tilt bail, an on/off switch and a separate volume
control, smooth tuning knob, smooth band selector, a power LED, an excellent
tuning indicator that is off when no station is being received, glows dimly for
off center tuning and glows brightly when a station is tuned in correctly. A 3
volt AC power jack is available for external power. The tilt/telescopic antenna
actually swivels a full 360 degrees for best reception for Shortwave and FM. An
internal antenna is used for Medium Wave - AM reception.
The dial markings for the frequencies received are:
AM: 530 kHz - 1710 kHz
FM: 88 - 108 MHz
SHORTWAVE:

The following comment about the rf-4900 was posted on www.eham.net:
"Poor image rejection. Offers good reception of medium to strong AM
stations on MW and SW. Other than that, its 'drift city' with constant
'Phantom' signals. Useless for utility stations. For a few bucks more -
buy a used Icom 720 and get superior reception with transmit

Notes Minimum tuning step is 50 Hz. Although the AR-8600-Mark II
has a 10.7 MHz IF output, its bandwidth is said to only be +/- 2MHz, so it
is not suitable for use with a standard video demodulator. However, a
special NTSC demodulator called the TV8600 designed exclusively for the
AR-8600 MKIIb or MkIIU supposedly has a 10 MHz bw. If NTSC demodulator
is installed, the 10.7 MHz IF output is no longer available.

Applications
The 95S-1A receiver is an excellent choice for any application
requiring computer-controlled tuning of narrow-band radio signals.
Several applications include:
Standard communications modes in the HF, VHF, and UHF bands (ie, AM,
FM, CW, SSB) for civil, government, and military networks.
Test equipment. Spectrum monitoring systems.
The Rockwell Collins 95S-1A general purpose receiver provides high
performance at low cost and supports a wide variety of radio receiving
applications. The 0.005 to 2000 MHz receiver is designed to satisfy
user needs for applications ranging across commercial, government, and
military communications, spectrum surveillance and test systems. It is
suitable for fixed station, shipboard, or transportable environments.
The receiver serial command protocol is simple and yet minimizes the
amount of data that must be transferred between the receiver and the
controller. The protocol supports single command operations or can be
operated in a multiple command mode that allows a sequence of commands
to be executed in succession.
Rockwell Collins has planned the 95S-1A receiver to be an open
architecture system, meaning that nonproprietary interface
specifications are provided to users, allowing third party
customization. Specifically, the memory in the receiver may be altered
to download user-written DSP software and alternate control languages.
The core Rockwell Collins DSP routines are non-alterable, but may be
utilized or supplemented.

The 95S-1(A) receiver is a 0.005 to 2000 MHz high-performance modular
receiver employing a direct conversion (homodyne) architecture. The
receiver frequency scheme uses only one mix: a single synthesizer local
oscillator tuned to the desired signal frequency converts a signal
directly to baseband, or the zero-frequency "IF signal." Baseband
signal waveforms are filtered and demodulated under the control of
digital signal processor (DSP) technologies developed and patented by
Rockwell Collins. The advantages realized with a homodyne, or direct
conversion receiver (DCR) architecture are simplicity and performance.
The DCR provides wide frequency coverage without spurious-generating
multiple mixes, and allows receiver selectivity to be obtained using
audio low-pass filters rather than the more complex RF/IF filtering
required with heterodyne receivers. Additionally, a majority of
receiver gain can be applied at baseband rather than in front end RF
stages. Because a DCR has no "IF," there is no receiver performance
degradation due to "IF" or image rejection. Similarly, there are no
"crossover" spurious responses because there is only a single local
oscillator.
The 95S-1(A) incorporates a high-dynamic range Rockwell Gallium
Arsenide mixer, preceded by internally tracking preselectors over the
20 to 2000 MHz portion of the tuning range. The receiver utilizes a
hybrid architecture for frequencies within the 0.005 to 30 MHz tuning
range, with parametric upconversion to a 51.2 MHz IF frequency.
An MFD synthesizer with progressive modulo-2 division provides
quadrature low-noise, spurious-free injection signals to the HF and
VHF/UHF mixers. The quadrature channels are identically low-pass
filtered, amplified (with AGC), and digitized by a sigma-delta ADC.
The DSP section utilizes twin 16-bit microprocessors to perform all
Finite Impulse Response (FIR) filtering, demodulation, automatic gain
control (AGC), and ancillary functions for the receiver. An additional
microprocessor provides communications and command execution control. A
complement of standard DSP functions is contained within a flash memory
integrated circuit, allowing field upgrades and customization.
Seventy-four filter bandwidths are standard, and five optional
user-defined filter coefficient sets can be transferred to the receiver
for specialized applications. Software support and documentation, for
developing user-defined FIR filter coefficients for use with the
95S-1(A) receiver, may be purchased from Rockwell Collins or can be
developed using standard FIR filter design tools. Two independent
demodulators may be operated simultaneously.
Audio output is generated by twin DACs, using any combination of
demodulated signals, routed through selectable low-pass filters, and
applied to headphone, line, and speaker amplifier circuits.
Digital 16-bit I/Q output is also available with user selectable
pickoff points in the DSP signal flow.
All parameters and command settings are preserved in nonvolatile
memory. This assures that the receiver operation will be restored
whenever power is cycled or a power interruption occurs.
The front panel contains a stereo headphone connector, status indicator
lights, and a power switch. Two rear coaxial input connectors allow RF
sources (antennas) to be either independently connected between the
receiver DCR section (2 to 2000 MHz) and the hybrid converter section
(0.005 to 30 MHz), or using the RF output (2 to 30 MHz) connected to
the hybrid converter section. The two frequency tuning ranges can be
multiplexed internally from a single antenna. The rear 9-pin serial
control connector allows for RS-232/RS-422/RS-485 control.
Independently adjustable left and right phone channels are available on
the headphone connector. The rear panel audio connector provides access
to a variety of audio signals including speaker, line, and phone
outputs.

This comment about the Yaesu frg-9600 was found on the Internet.
"I have owned the FRG-9600 for a few short weeks. I just can't figure out
the scanning set up of this unit. It has 100 memory channels all of which
I can fill with frequencies to listen to but when it scans and stops on a
memory channel the display digits start to blink from left to right and
then it resumes scanning cutting off the conversation. I just don't get
it." (see rest of review at www.eham.net).

Comments about the AR7030 from
Radio Netherlands Media Network: AOR AR-7030 PLUS
The AOR AR7030 PLUS follows on the successful AR7030 launch in early
1996. There are a number of improvements in the new version. ...
www.rnw.nl/realradio/html/ar7030plus.html
- Increased balance of the mixer for greatest IP2 & IP3
- High tolerance 0.1% components in DDS ladder for low noise
- Enhanced RF attenuator operation for minimal intermod
- Higher spec wire aerial input transformer for minimal mixing products
- Ceramic metal cased 4 kHz (displayed) AM filter fitted as standard (typical bandwidths: 2.2kHz, 4.0 kHz, 5.3kHz 9.5kHz)
- Bourns optical encoder for the smoothest DX tuning
- Features CPU fitted, 400 memories, multi timers and alpha tag
Otherwise, the PLUS's external appearance and functions are similar
to the AR7030. The receiver was designed by John Thorpe, the
designer of the popular Lowe HF-150. The receiver continues the
British trend for producing high-quality receivers without frills at
reasonable prices.
Other receiver features and capabilities include:
- 0-32 MHz coverage in AM, AM synchronous, CW, USB, LSB and DATA modes.
- Remote control keypad enabling direct frequency entry.
- Antenna connectors are two: 50 Ohms and 600 Ohms unbalanced input for wire antennas.
- Four IF filters with the option to add two additional filters.
- Two VFOs.
- Memories (400, up from 100 in the AR7030) that store
frequency, bandwidth, mode, passband or BFO setting, squelch and scan
include/exclude.
- Computer control.
The following review the AR7030 PLUS was found on the Internet:
"The AR7030 PLUS continues the nested menus, displayed on the front
panel display. The user must 'drill down' to find settings and options.
It is quite different from the Japan Radio Company NRD-series receivers
that have almost every function on a separate knob or switch. Our
listener feedback suggests the menu structure approach is a 'love-hate'
relationship with few users in the middle ground.
The AR7030 was an excellent receiver for the price, especially
in Europe. Though we have not tested the PLUS version, the improvements
cited by AOR UK should only make the receiver better."
The AOR AR7030 received the World Radio TV Handbook "Best Table Top
Receiver" award for 1996-97.
The NB7030 multi-option is not fitted as standard to the AR7030
PLUS, just the 'features' CPU is fitted. Should you wish to add the
hardware noise blanker and audio notch filter, order the UPNB7030
(slight saving in price).

Digital signal processing uses an algebraic operation method for
signal detection, generation, inference, processing, or transmission.
Compared to analog signal processing circuits, digital signal
processors are more advantageous: They only require less precise
components; they are robust against drift and interference; they are
easier to integrate with high precision; and they offer greater
flexibility with software processing. The DSP IC consists of a
multiplier, an adder-subtractor, and a memory (shift register). The
digital signal processing algorithm is based on repetition of
operations such as data readout from the memory, multiplication,
addition and subtraction.

VR-5000 COMMUNICATIONS RECEIVER
$995
0.1 - 2599.99998 MHz * LSB/USB/CW/AM-N/AM/WAM/FM-N/WFM
All-Mode Wide-Band Receiver (*Cellular blocked)
The exciting world of communications monitoring, from Longwave to
Shortwave to Microwave, comes to your home or station with Yaesu's new
VR-5000 Communications Receiver.
Despite its incredibly compact size, the VR-5000 provides coverage of
100 kHz through 2599.99998 MHz (cellular frequencies are blocked) on
all popular operating modes: LSB, USB/ CW, AM-Narrow, AM, Wide AM,
FM-Narrow, and Wide FM. Making operation simple and efficient is the
"Auto" mode, whereby the tuning steps and operating mode are
automatically programmed according to the frequency you have selected.
You won't miss those quick, important transmissions with the VR-5000
When monitoring on the "main" displayed frequency, you can
simultaneously listen to a second station operating within 20 MHz of
the main frequency in the AM and FM-Narrow modes. This can be
especially helpful while monitoring public safety communications.
Featuring a handy world map showing the station's location, the special
Shortwave Broadcast Station Memory Bank includes several different
frequencies from a number of popular shortwave stations, including
Voice of America, the BCC, Radio Japan, Voice of Russia, etc. The
operating frequencies may be changed by the owner, to keep up with
changing station schedules!
To aid in finding band activity, the VR-5000's Real-Time Band Scope,
used while operating in the "VFO" mode, will sweep the band in search
of activity, displaying the received signals graphically according to
frequency and signal strength. The sweep width may be set to
100/200/250/300/500 kHz and up to 1/2/2.5/5/10 MHz, and you can also
adjust the sweep steps for best resolution in the frequency range being
observed!
The incredible 2000-channel memory capacity of the VR-5000 allows an
astounding array of operating possibilities! The memories may be
arrange in up to 100 Memory Groups, and you can attach an alpha-numeric
label to both Memory Channels and Memory Groups to aid in channel
identification. The memories store operating frequency, noise blanker
status, and DSP information separately, so each channel is optimized
for best reception.
The VR-5000's versatile scanning system allows lightning-fast sweeping
of operating frequencies, so you won't miss any of the excitement on
the bands! The scanner allows you to select from three scan-resume
options, too: "Delay" Scan, which lets scanning resume after a
programmed interval of waiting on an active channel; "Pause" Scan,
which holds on an active channel until the incoming signal disappears;
and "Hold" Scan, whereby scanning stops when activity is encountered.
There is a wide array of scanning features available to the VR-5000
user: ? VFO Scan Sweeps the entire frequency range of the receiver (0.1
~ 2599.99998 MHz). ? Memory Scan Choose from scanning of all memory
channels, or channels within a particular memory group. ? PMS
(Programmable Memory Scan) Scan within user-defined band limits, as
though you were on a VFO. As many as 100 band-limit memories may be
utilized for the setting of scanning borders. ? Smart Search^(TM)
Automatically loads up to 100 channels where activity is found.
?Main-Sub Two-Channel Scanning Allows watching of the Main and Sub VFO
frequencies without listening to them simultaneously. ? Priority
Operation Allows operation on one channel while periodically watching a
"Priority" channel for activity. Operation will shift to the Priority
channel if it becomes active.
The optional DSP-1 Digital Signal Processing Unit includes a number of
features which can significantly enhance reception through improved
interference rejection. ? Digital Bandpass Filter (SSB/AM/FM Modes)
Provides razor-sharp selectivity for reducing adjacent-frequency
interference and for shaping of the incoming station's audio frequency
response. Both the low-cut and high-cut frequencies of the DSP Bandpass
Filter are adjustable. ? Digital Noise Reduction Filter The DSP will
analyze the incoming passband and suppress noise which is not directly
associated with the incoming signal, providing quieter reception. ?
Digital Notch Filter Automatically notches out annoying "beat" signals
("heterodynes") which can spoil reception, especially during Shortwave
operation. ? CW Narrow-Bandwidth Peaking Filter Provides ultra-narrow
bandwidths of 25/100/200/400 Hz for single-signal reception. ? CW Tone
Pitch Control Allows you to adjust the center frequency of the CW
filter for most comfortable reception.
Comments about the Yaesu VR5000 from www.eham.net
"Selectivity OK, sensitivity good, gets overloaded with large
antennas on HF. Excellent sensitivity above 1 GHz compared to
the AR-8600 (Mk I & Mk II)"
"The VR5000 is difficult to operate with the multilayered menu controls.
It had insufficient image rejection and it locked up on the fifth day,
requiring me to hard reset the CPU which erased all memories."
