Yaesu FT2600M problem
I have a Yaesu FT200M which I have installed in my truck for the purpose of transmitting an APRS signal on 144.390. Each time I set the radio on this frequency, turn the radio off and then back on, the frequency changes to 144.385. Turn it off and on again and it tunes to 144.380, etc., etc.
Anyone have any idea how to turn this "feature" off so the radio stays on 144.390 when I turn it on and then off? I've read through the manual but don't see anything. Thanks. |

Tom, I suspect that there might be a cabling issue that is causing the radio to erroneously register a push of the "down" button on the microphone (if that model is so equipped). I ran into a similar issue with an FT-2800M a few years ago; that model in particular was also susceptible to erratic behavior from RF coming in through the microphone line. I guess the best place to start would be to disconnect your APRS interface and see if the problem persists. If it goes away with the interface disconnected, it could be a cabling issue.

It is possible your frequency adjust knob is set right at the point where it changes frequency. This could be purely random, or could be due to a defective rotary encoder. Another possibility might be that the radio has a CMOS battery that is getting weak. Fred K4DII |
