I was trying RTTY for the first time with my K3 in AFSK-A mode today and ran into a problem. Every now and then I would lose monitor and receive audio on all data modes except DATA-A. That is, I would start sending (using cocoaModem on my MacBook), the K3's power meter would indicate output power, but I wouldn't hear any monitor audio from the external speaker attached to the K3. I tried changing the data mode to DATA-A and monitor audio returned. Switching back to AFSK-A, I now had no receive audio. None of the other data modes had any receive audio except DATA-A. Cycling power did not correct the problem. Changing to CW or SSB mode and back to DATA did not correct the problem. The only thing that seemed to bring back receive audio was pressing the A/B button to switch VFOs. (I have the sub RX, but it was not turned on.)
This happened 4 times. I tried re-loading the FW (version 3.44), but it happened again. Each time it begins with no monitor audio during transmit, then, after changing to a different data sub mode, no receive audio. Pressing A/B is the only thing I've found that will restore audio to the other data sub modes. DATA-A mode always works fine. Anyone else noticing strange behavior in DATA modes? 73 -- Joe KB8AP ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
