I just finished building my K3 to the point of the test and calibration stage, where I encountered some issues. SYN calibration went fine, and the filters are set up. When I got to REF CAL, I found I couldn't use WWV because I wasn't hearing anything. I reseated the KIO3 board as well as the 2 daughter boards and managed to get a crackle from the speaker at power up and power down but still no audio.
I used a freq counter for REF CAL but when I got to TX Gain Calib, I received the following error message using the latest version of the K3 utility: Starting 5 watt calibration Calibrating at 1.900 MHz IsSamplingComplete: Unexpected response "DS@@@@@>>@\x80\x80;" to "DS;" State 157 Calibration power settled at " 0.0 W ;" 5 watt calibration failed Elapsed time: 6 seconds I tried manual calibration on different bands but that failed also. I haven't seen any references on the reflector to an ERR TXG mentioning a State 157. I did recheck my filter settings and they seem correct. I've emailed k3support but thought I'd check here in case someone has seen this version of the ERR TXG issue. Does the fact that I could connect my laptop successfully to the K3 and use the utility indicate that the audio issue is probably with the audio daughter board and not the main KIO3 board? Thank you for any ideas on how to resolve either issue. -- View this message in context: http://elecraft.365791.n2.nabble.com/TX-Gain-Calib-state-157-error-and-no-audio-issues-tp5129241p5129241.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ 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
