I was aligning the SSB filter settings on my K2 and listening on another radio. Once I had it set, I started a QSO on 80m and was making further adjustments to the filters. I didn't notice it at first, but I started hearing the last 5 seconds of my transmissions at approximately S5. Thinking that someone was recording my voice and playing it back, I commented to the guy I was speaking with but he couldn't hear it. We thought this was strange since on 80m generally, you can hear about anyone.
Over the past few weeks, I have come to determine that there is something strange going on. It is happening on two transceivers, the K2 and a Yaesu FT-897D. When I key the mic and speak quickly, saying for instance "Test" and quickly release the PTT, I hear my signal after about 1.52 seconds of delay. This is considerably shorter than the 5 seconds of rebroadcast noted above. If I send CW, the letter "K", I will get a "K", (dah di dah) back. If I send a string of dots at 12wpm, I will get at most three dots back. So if I send one dot, I get none, two I get one, three I get two, four and higher I get three. I can only assume that the first dot is triggering a repeater?? The reflected signal also increases with power output. It is about S5 with 100w and about S8 or so when I run the amp. It is not a person recording me since I quickly tuned around the band and even switched sidebands several times. The returning signal is always exactly on frequency. It doesn't happen on other bands that I am aware of. It doesn't happen all the time but lately I noticed it consistently during the day. I made several recordings ( I can forward them) and it looks like the signal is always approximately 1.52 seconds delayed and lasts about 1 second. It can't be long path propagation since 1.52 seconds works out to about 282,000 miles. My antenna is pointed at a cell tower. I also have large LORAN towers and other sea navigation towers about a mile from me. Anyone ever hear of something like this? It must be a repeater of some kind.
