Re: TM-271a Fails to Transmit

Is there a reason for not using the data jack on the back of the radio, instead of the microphone jack?

You may want to get your meter out and check it out.

Did you build the cable or buy it?

Hello,

My APRS station consists of a KPC3+ and at Kenwood TM-271a radio. Yes, the TM-271a is not the “e” model. The cable from the KOC3+ plugs into the mic on the front panel and speaker jack in the back. 


When APRS transmits, the TNC Tx light turns on, but the TM-271a does not key up. The TM-271a baud is set at 1200.

reading through the manual, I do not see a setting I missed.

Thanks for any help on this.
