Hi Paul, Could you please post the TX gain parameters recorded by the K3 Utility at the 50 watt level for all bands?
If there is a significant difference in those gain parameter values between adjacent bands (say 30 and 17 meters) and the value on the 20 meter band, that may be an additional clue. The bandpass filter bank may be at issue here since you've checked the appropriate LPF. If there's a problem with the relay contacts on the relevant BPF or LPF section, that may also reduce the TX signal level and force an elevated TX Gain parameter value for that band. Keith, WE6R has a checklist of steps to try when diagnosing low TX output power. I recall he said to contact supp...@elecraft.com for that document. 73, Mike, K8CN ______________________________________________________________ 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
