Ive ad the OT3m for some time and finally for it up and running in my f150 using the garmin 350 and had been fine for some time but I had noticed that after an output of aprs data the unit would not work -- well work the transmitter -- htx-242 would still continue to transmit -- I pulled out an ht to fins out what was going on -- seems lie it would transmit the aprs data then it sounds like just like the mic is open and there is a bump bump bump bump I have recorded it and will try to upload the audio of it -- if you listen to it -- that is my aprs data then the bump bump bump -- I killed power to it and you can hear someone else's data ( as being received via an ht )
I have the radio mounted under the rear seat and had made my own cable to extend the connection to under the dash that has the OT3m - I created the cable out of shielded cat5 cable one end is in the radio the other is connected to the ot3m via a shielded serial connector -- there is the fmi cable connected to it as well I also fitted some rf chokes to the cable I made --
Im kinda at a loss
other issue is I wanted to update the f/w figuring that might solve the issue but upon connecting to the computer ( via usb ) and updating through the config program I get an " invalid address 8000 - valid range 0000-8000 ???? wtf --- my firmware is 56294 and wanted to go to the 56398
thanks for any help
