[Elecraft] [K3] RX Audio Distorted on FM
Happy Thanksgiving to All, Just installed the KFL3B-FM Filter to my older K3. Tuning around on 10 this morning I heard a station, but things just didn't sound quite right. I fired up the 817 and found that the transmit audio sounds great, but the receive audio sounds distorted as though it were being overdriven. I've update all the firmware and haven't been able to find any references to receive audio. Any suggestions? Thanks..

[Elecraft] [K3] RX audio distortion on FM
Afternoon Don and the group, Thanks for the quick response.. We're running the stock 2.7 filter in slot 3 and the FM filter in slot 1.. CW and SSB all running fine with no issues.. In fact, the FM didn't sound half bad coming thru the 2.7 filter while playing around with it this afternoon. Filter has not been moved since the day I put it in, just added the KFL3B-FM to slot 1. I've gone thru the config process and made sure everything was on and verified that in FM mode, XFIL1 appears on the screen. I setup/verified the filter options using the K3 utility last night and all seemed well there.. I did noticed last night once everything was installed that the background static was a lot higher when I kicked it into FM mode so I'm willing to bet I am over driving the audio path somewhere. Strictly using the FM filter for FM.. As mentioned I have not had any other issues with audio quality on any other mode until I try to listen to anything on FM either on 10 or 6. Other than that, radio (Serial # 1051) is stock with no other modifications.. Since the bands are now pretty dead, I am doing all the testing with my 817 in house. As mentioned, TX audio sounds really good, the RX audio though sound just plain distorted as though it were being over-drivin or I'm not quite centered in the filter passband..

[Elecraft] [K3] RX audio distorted on FM
Good evening All, Well I've had a chance to play around some more and now found that at least with a local signal from the 817 the audio distortion on FM receive seems to have mysteriously disappeared. One question I still have though is that with an antenna hooked up and listening on either 10 or 6 meters when the band is quiet (night time with the pre-amp and attenuator off), does the background static get at least twice as loud if not more when you go from any of the modes to FM? Seems like it did not does this when I had just the 2.7 filter installed into slot 3. Tried turning the slot 1 filter off, but it still defaults to it when in FM mode so I can't compare unless I go back in and physically take that filter out. Thanks for your responses..
