Hi Chris, Does your K2 transmit OK on those bands, i.e. at full power output?
The fact that other bands have normal sensitivity indicates that the main receiver functional blocks are OK. The bandpass filters for 20 and 80 meters have only one component in common, relay K3, but that relay selects 80/160 meters or separately 20/30 meters by adding additional shunt capacitors for the lower frequency band in the proper filter section. I would check your per-band settings to be sure that you haven't inadvertently selected an antenna port that isn't connected to the proper antenna for one of those bands OR that a separate RX ANT is selected when you have no antenna on that port (presuming you have the 160 meter/RX ANT module installed). 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
