Yes, I have VOX enabled and FL1 with BW=2.8kHz is set as TX filter for all modes - no ERR_TXF. The K3S switches from RX to TX, the red TX LED blinks and I can hear my Morse code on another radio when TXing into dummy load. Just output power in CW mode is minuscule to 1 bar on RF indicator, read as 0 or -15 dBm with K3 Utility Calibration. I measured 103 mV pk-pk on 50 Ohm load at ANT1 connector giving 26.7 uW or -15.7 dBm where 12 W should be. CONFIG:KXV3B is NORm. Everything is fine in SSB and SSB+CW mode but not with CW MODE selected.

The EE_INIT or reload of DSP 2.88 and upgrade to beta FW ver 5.60 does not help. I cannot find older FW on Elecraft website to check out. The DSP outputs only a very small 15kHz signal in CW MODE. The TUNE and Calibration insert CW carrier and of course fail. TX_ALC off did not help either. Would you have any ideas how to fix this problem? Thanks, Marian, WS9M ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
