Hi. I just built a QMX high band 10-20m. Hope you can assist me in troubleshooting. Bear in mind, this is my first ever electronics kit build... It's a standard build, with rev 2 board. Receive and Tx works on all bands, but 20m (only band on LPF0) only transmit 3w, and audio-sweep and image sweep are "low", -13 sensitivity for audio sweep. Image sweep varies(!) from -34 to -26. In band configurations, if I change 20m to LPF1 it gets a lot better in terms of either sweeps. Hence, I gather the problem must be somewhere in LPF0. I have resoldered all the usual suspects but to no avail; L506, L511, capacitors and inductors in LPF0 and checked the diodes. Any suggesting about how I can proceed in identifying this issue??
Thanks a lot for your input!!
Kind regards,
LA7HM Jo?
