VX-8DR – A Devoted APRS Users Version of the VX-8R Series
The VX-8DR APRS®/GPS/Bluetooth® Handheld Transceiver is an additional version of the VX-8R that includes not only its solid features and specifications but also new expanded APRS® capabilities to meet the needs of even the most active APRS® user. The VX-8DR has the same appearance as the VX-8R and uses the very same accessories.
Key Additonal APRS® Features of the VX-8DR compared to our VX-8R include:
• Smart Beaconing ™ Function: When using APRS® for position tracking, the beacon timing is automatically adjusted to your traveling speed and location to plot a smoother trace to match your position and movement on a map.
• The number of Station List memories has increased from 40 to 50.
• The number of APRS Message memories has increased from 20 to 30.
• DIGI-PATH route indication function: The APRS® Packet data includes Digipeater routing info.
• Heads up compass display to the GPS Screen: Your traveling direction is always toward the top of the display. • The Message received LED flashing rate is selectable.
• The number of DIGI-PATH route settings is increased from 1 to 7.

Display can be customized to include pictorial icons or the input voltage. Engaging the Spectrum Scope function, the high-resolution display will indicate relative signal strengths on adjacent channels up to +/-50 channels!
Integrated APRS Operation
APRS ® allows you to communicate your location to other APRS® stations with your location, speed, and heading displayed on your radio! The VX-8DR supports 1200/9600bps APRS ® data communications (B band only).
Access the worldwide standard APRS® system to exchange your positions and messages. The optional FGPS-2 unit is required automatically display your station information.
When you receive signals and information from other APRS stations, the VX-8DR displays their positions, heading directions, messages, distances, icons (43 available), weather information, object etc.

Smart Beaconing ™ Function
When using APRS® for position tracking, the beacon timing is automatically adjusted to your traveling speed and location to plot a smoother trace to match your position and movement on a map. SmartBeaconing™ from HamHUD Nichetronix is able to modify its own beacon rate in response to the motion of the vehicle that carries. Since the APRS network has limited bandwidth, SmartBeaconing™ transmits an optimal amount of position information with a minimal amount of QRM to other network users – making VX-8DR users some of the most “efficient” on the network.

Optional GPS Operation
The optional GPS Antenna Unit FGPS-2, which is based on a 12-channel receiver, provides GPS data. You may display your exact current position (latitude / Longitude), heading direction, moving speed, altitude etc. The optional FGPS-2 can be attached to the radio using the microphone input jack so that you may simultaneously enjoy total Hands-Free Operation using the optional Bluetooth headset, even though your radio is attached to your backpack, belt, etc.
Dual Band AF Dual Monitor
Listen to AM or FM radio stations while monitoring two HAM frequency channels! Two independent Amateur Band Receivers will allow you to listen to your favorite AM or FM broadcast station and monitor two different amateur bands (“Band A” and “Band B”) at the same time.
The Bluetooth® capabilities widely know and utilized among users and enthusiasts of our VX-8R, FTM-10R/SR and FTM-350AR radios, are also available with the VX-8DR. The optional Bluetooth® Unit BU-1 makes it possible to operate hands-free with the optional water Bluetooth® headset BH-1A (stereo) or BH-2A (monaural). Also enjoy your favorite FM broadcasts in stereo with the optional Bluetooth stereo headset (BH-1A) and earphone (FEP-1)!

Icom IC7200 HF/50mhz Transceiver
The IC-7200 HF/50MHz transceiver maintains all the traditions of high quality engineering that you expect from Icom. Rugged in design and easy to operate, the IC-7200 utilises the latest digital functions including digital IF filter, twin PBT and manual notch filter which are normally associated with more expensive models. The IC-7200 is ideal for field operation or at home in your shack and is designed to be one of the most practical rigs available.
The IC-7200 utlises the latest IF DSP technology including digital IF filter, digital twin PBT and manual notch filter.
AGC loop management
Distortion and blocking from strong nearby signals are prevented by placing DSP functions inside the AGC loop. The AGC time constants are selectable from fast, slow and off for each operating mode.
Digital IF filter
The built-in digital filter allows you to flexibly select the filter width and shape from soft and sharp* and provides cutting edge filter characteristics. The twin peak filter for RTTY mode improves the frequency response and provides better readability in RTTY mode. * Filter shape is selectable for SSB and CW modes only.
Digital Twin PBT
Tailor your IF passband with the Twin PBT by electronically shifting the upper and lower edges of the IF filter. Depending on the use of the concentric knobs, you can either narrow the IF passband, or shift the entire passband to eliminate interfering signals.
Manual notch filter
The manual notch filter delivers more than 70dB of attenuation. Strong interfering tones will be eliminated without adversely affecting the AGC loop performance. On the bottom right of the front panel, a dedicated control knob adjusts the notch filter frequency.
Digital noise reduction
The digital noise reduction reduces background noise and improves the signal-to-noise ratio. The noise reduction level is adjustable in 16 steps which improves the readability of voice and data signals.
Digital noise blanker
The noise blanker reduces pulse-type noise such as engine ignition and sparking. The NB level and width (blanking duration) are adjustable in 101 steps.
High frequency stability
The IC-7200 has the built-in high stability crystal unit. It provides a very high frequency stability of ±0.5 ppm suitable for RTTY operation.
USB port for PC control The IC-7200 can be controlled by a PC through a USB port using the CI-V data format. In addition, modulator and received audio can also be transferred over the USB cable. By using appropriate external software, you can record incoming calls and/or transmit preprogrammed messages from your PC.
RF speech compressor
The digital RF speech compressor increases your average talk power in SSB mode. Even when the compression level is increased, the DSP controlled RF speech compressor provides low distortion audio.
CW mode operation
Full break-in, selectable CW carrier point (USB or LSB) and adjustable CW pitch are standard.
High stability transmitter
The DDS (Direct Digital Synthesizer) improves the C/N ratio and creates a noiseless, clean transmit signal.
100W output power
Using proven RD100HHF1 MOS FETs in a push-pull PA circuit and with a dual-fan cooling system, the IC-7200 provides a stable 100W output even during high duty cycle operation.
Tough construction against water intrusion
The buttons and knobs on the front panel have water resistant protection, providing a measure of protection against water intrusion. * IC-7200 is NOT waterproof.
Rugged design for outdoor use The IC-7200 has a rugged build, which means that the enjoyment of this rig is not limited to your shack.
Front mounted loud speaker
The front-mounted speaker provides clear audio sounds that can be clearly heard without impediment during operation.
