Hello Readers, i need to understand which point in the signal path i have to control/measure to investigate further damages in my K3 after water damage event. yes, VOX is on. When i have the place where the issue starts, i want to understand what is causing that behavior. Currently receiver is working, but i have no RF output from PA. So i want to check the TX path. During TX i see no output from DAC to TXIF in CW, i would expect a 15KHz signal there. But i find during RX on ADC an input signal(bandwidth 2Khz @ 16KHz). I only see an 8230KHz signal at roofing filter input.
First: ist this assumption right, to see 15KHz after DAC output? If yes on wich pin of which jumper? If correct, what can cause, that the signal is not appearing. Probably i could replace the RF board by a new one, but i want to avoid it. vy73 Harald DD0VS ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
