I sent this to K3 support, while waiting their answer I ask here also.
Serial is 0691.
Last week I noticed that my K3 has no TX output on 6m band.
I run Transmitter gain adjustment procedure on all bands.
I noticed that 160m and 10-6m has problems and can not finish properly the adjustment procedure.
Here are my results using a dummy load:
Measures RX: 14.9V, 1.19A, PA 24C, FP 20C
Band, Reaching Power, SWR, Voltage, Current, Error
160m, 2W, 1.2-1, 14.7V, 2.78A, ERR TXG
80m, 5W, 1.0-1, 14.6V, 3.27A
60m, 5W, 1.0-1, 14.6V, 3.33A
40m, 5W, 1.1-1, 14.6V, 3.30A
30m, 5W, 1.0-1, 14.6V, 3.38A
20m, 5W, 1.0-1, 14.6V, 3.19A
17m, 5W, 1.0-1, 14.6V, 3.19A
15m, 5W, 1.0-1, 14.6V, 3.25A
12m, 5W, 1.0-1, 14.6V, 3.24A
10m, 5W, 1.0-1, 14.6V, 3.35A, ERR TXG
6m, 0.1W, --, 14.8V, 2.19A.
For the measurements I replaced the KAT with the antenna interface card, so the problem is not in KAT.
I guess that possible components that can cause such problems are LPA and maybe the SWR Bridge.
What components in the LPA or in SWR bridge can cause such?
Has anybody had similar problems?
