Reasonable Radio For Packet

  • 3/16/2016 Ordered LEIXEN-VV-898 for $70 from Amazon for a data radio on 145.01

    • NS7C: Haven't tried on on packet, but it should work at 1200, maybe even 2400. It is supported by the latest daily of CHIRP if you have the right programming cable (which uses the bogus Prolific chipset, good luck finding the driver). By the way, the buttons on the mic are for frequency entry, it does not do DTMF. You'll have to provide your own DTMF mic for that. You will want to do that anyway because you will hate the Up/Down buttons on the mic. The Up button is on the top where it belongs. The Down button is on the opposite side from the PTT button. If you hold the mic in typical fashion, when you push PTT, you will also push Down. It will take some training to unlearn decades of how to hold a hand mic.
    • N7XY: I bought one and am not terribly impressed. Tone encoding didn't work on the 440 band (it did on 144). I decided to use it for an APRS tracker.

    • This one is on 144.39 so had hoped to use it for APRS. Service monitor says transmit power is nearly 5 watts, but on receive it takes a couple of microvolts to see anything out of the noise. Maybe I'm expecting too much.
    • Frank: I have a 8621A. When I first received it, it was near deaf. Or totally deaf, don't remember. I had sent it back to MFJ (lazy, no time, was brand new and I expected more) and it arrived back on my door step in the same deaf condition. So I took a look at it myself.

Basically, the solder job was crap. I resoldered everything. What fixed the problem was the solder joints on the crystal itself. Since the ground is on large area of copper, that solder joint just needed some extra TLC. Once it was soldered properly, the radio worked like a charm.

Take a look at your solder joint, especially in areas where cold joints can happen easily. Check the joints of the crystal. (I still recommend spending a bit extra time to resolder every joint).
