When the 80 meter band goes long you may be far enough from the FL station so that you can copy OK, but too close to the GA station.
If the signal strength was about the same from both stations, then there could be ionospheric conditions that may be affecting the GA signal. Olivia is generally pretty resistant to most interference and the 16/500 mode uses the slower 31.25 baud rate which means the symbols are reasonably far apart for many 80 meter ISI problems, but it is possible that that path has severe multipath. Even though the FoF2 is way down at night in our area (not always as low in yours), I am barely able to copy stations 150 miles away, but do OK with stations much farther away. Our CW nets can barely function due to being so close. If they could only move to 160, they would have much stronger signals. Last night I called CQ on 160 on 1.808 + 1500 Hz and had a station come back to me but I could not print him and yet he apparently could print me OK. I told him to go to MFSK16 and I was able to print him to get his call. He may not have been patient enough to keep trying it, and must have thought that I was not copying him because then I finally locked in on him. I never used to have any problem with MFSK modes, but lately I find it really difficult to get locked in and have found that I often have to adjust my RIT for -20 Hz. I tried calibrating my sound card but I must have some kind of offset problem. I would like to try working more with DominoEX, especially with FEC, but it has not been easy to find anyone else. Calling on DEX11 seems to not be successful on bring up anyone on 160, even with RSID enabled. 73, Rick, KV9U >> >>Right now I'm copying a QSO where the stations are using Olivia >>16/500 on 80M.
