Last night I was talking to a W9 and had severe heterodyne QRM. I listened and it turned out the QRM was from Jean. I called him and we QSO'ed for a few minutes, although condx weren't as good as the night before.
I was doodling around last night playing with an sdr and saw your carrier again and came down to listen and caught the end of your QSO with the W9 and started to tune away when you said you were shutting down then heard you switch to french! I'm not a french speaker but you sounded pretty fluent.
I could hear Jean a bit with my low loop, but you were booming in as usual.
Good luck with the intermittent. Those are the most frustrating to solve.
