Well folks. I have a bit of a problem and don't have a clue what may be going on. I have a Kenwood TS-440S that I have had for at least 10-15 years now. Up to 2 weeks ago everything was working fine. I work phone and CW with the radio. Here's the problem. When I work phone or CW on 20,15,10 meters the audio and CW tone is distorted. It sounds like RF is getting back into the rig but I have everything grounded as well as an extra ground wire from the mic plug to the radio ground to be sure I don't have a loose ground on the mic. Listening on another radio, the CW tone has a bit of a distorted kind of chirp. Hard to explain the sound. 50db/S9 it is loud. If you were to hear me at S4 you probably wouldn't notice it at all. The phone audio is unusable. I am using a Mosley CL-33 at 60 feet with a well grounded tower. This is the same set up that I have used for years. Kenwood antenna tuner as well as the internal tuner. I have changed configurations around and nothing changes the problem. Here is where it gets stranger. I have a 40 meter inverted V at 40 feet that I also use on the same rig via antenna switch. When I work 40, phone or CW, NO distortion. Clean audio on phone and a nice clean tone on CW. Still through the same tuner and antenna switch. Again, same setup on the rig and antenna for 15 years. I can get by with it on 20,15 and 10 CW but I would really like to be able to work phone there also as I have done since I was licensed in 1974. Only having 40 phone is getting a bit boring. Anyone have any ideas what might have happened in the last couple of weeks to distort the upper bands? I would be very grateful for any ideas or any help anyone can offer. I am going to post this everywhere I think there may be a person that has a thought concerning this problem. Thank you in advance. 73, Gary W.
