Hi Stan, You didn't indicate other options besides the DSP module that are installed in your K2, but here are some possible gremlins in order of decreasing likelihood of being the culprit:
1) Check the ATT/PRE switch when on 40 meters to be sure the ATT is not switched on. 2a) If you have the KAT2 auto-tuner installed, check the ANT1/2 switch to be sure you have not inadvertently selected the wrong antenna port for your 40 meter antenna. 2b) Presuming that cause #2 is not the culprit, tune the auto-tuner while the K2 is on 40 meters and connected to a good 50 ohm dummy load. Disconnect the dummy load and repeat the XG3 test. (Alternatively, you could place the KAT2 into Bypass mode - see the KAT2 manual for details) 3) If you have the K160RX module installed, go into the MENU and select the RANT parameter while you're on 40 meters - verify that RANT is "OFF". 4) Although very unlikely, one of the filter components or a relay in the 40 meter lowpass or bandpass filter sections may have a bad solder joint that finally was jostled loose in the last week. You can follow the signal tracing directions in the K2 manual if you've exhausted possibilities #1 - #3 above and need to check for an actual physical disconnection on the RF board. I'm curious to know of your findings...... 73, Mike, K8CN -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-almost-deaf-on-40-meters-only-tp7576624p7576625.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
