As I understand things, the Chinese rip-off does NOT contain switchable low pass filters, so the harmonic output is unlikely to be very good.

Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.

Probably you would still get change from £2k, which is less than the cost of many HF transceivers, a linear and a beam on a tower plus rotator. I guess operators now have confidence in this after many years.
The advantages are many. The dish is small, fixed and no HF rig is needed. Within the footprint of the satellite DX is always available and without QSB. In many ways I am quite surprised many DXers have not gone for this option already.
I prefer experimentation.

Incidentally, I heard recently about someone in the UK working a German station who was mobile on Oscar 100!! I think the station in the car was listening on the webSDR but using the 2.3GHz uplink to the satellite.
I suppose a low(er) cost option is to make or buy a TX transverter and helix and listen on the webSDR.
My gear was turned on at about 1245z
UPDATE 1330z: So far, 59 stations have spotted me.
As a club project you can even buy 5 kits (yes five kits!!) for $150 total. Individual kits are just $39.
See www.hfsignals.com .
At about 1830z I QSYed from 8m and instead went on 10m FT8 with 2W.
UPDATE 2021z: 10 stations have spotted me with the best PU2YFR (9602km). Now QRT.
There was an interesting piece on the BBC website this morning about the state of the world. After a relatively peaceful time since WW2, it ...
