Enjoy high performance packet from 1200 to 9600 baud on 2 Meters, 24 hours/day.
Why tie up your expensive 2-Meter rig? You can dedicate MFJ’s PacketOnly™ transceiver to your favorite packet channel for continuous 24 hour-a-day duty.
The MFJ-8621A PacketOnly™ radio is a 2-Meter FM data transceiver built exclusively for high performance packet. You can operate all data rates from 1200 to 9600 baud right out of the box!
MFJ-8621A is compatible with all TNCs having hardware DCDs. Also compatible with most TNCs having software DCDs.
Getting started couldn’t be easier - just plug in an appropriate TNC cable (also available), your antenna, 12 VDC and you’re ready to enjoy error-free packet.
You get up to 5 Watts output - ideal for packet. It’s plenty to cover your operating area without disrupting distant nodes.
Direct modulation lets you use all data rates from 1200 - 9600 baud without modification.
Ultra-fast PIN diode switching gives you near instantaneous changeover between transmit and receive.
Dual conversion receiver, 0.25 uV low noise preamp, double-tuned front end gives you excellent weak signal reception and freedom from intermod.
Narrow 10.7 MHz IF filter and special full data-bandwidth 455 KHz IF filter gives you optimum passband and steep skirts for error-free data reception.
Unsquelched audio feeds directly to your TNC for lightning-fast DCD response.
The receiver local oscillator is crystal controlled. It runs full-time - no start-up drift or synthesizer lock-up delay.
It is a tiny 5" x 5" x 1 ½", and it draws just 15 mA on receive and less than 1 Amp on transmit on 12 VDC.
