Looks like the PA of my FT-817 gave up the ghost. Maximum 50 - 100mW out of the transceiver, whatever I do.
It looked for a day or two like my WSPR signals on 10MHz were soewhat down, and quite right, minimalist output there.
I have decided to leave it as is for now, a bit of output is still there, but a repair has to be done at a later stage.
Also, I decided to move the FT-817 *as it is now, on 10 meters, so listening and *really* WSPRing on 28.126120 MHz if anyone pops up there I will be leaving the reporter on and with an estimated output power of 50mW, running concurrently with SpectrumLab for QRSS on 28.125900 - 28.126000 MHz, running with a full wave 10m loop inside my balcony, tuneable from 10 - 20m with reasonable efficiency.
Filters: Crystals, LC, Mechanical, SAW, etc.

*I thought this was an interesting look at filters and crystals. And even
mechanical filters. Remember: Those little SAW containers became the
