Another amusing SOTA outing on 10GHz:

Four countries worked.

Looks an impressive effort on 10GHz Richard, I guess you’re well satisfied with that?

In reply to M1EYP:

Indeed; I gave up when my hands turned blue with the cold. A pity as I was close to equalling the 70cm QSO total from the summit.

The following just dropped into my inbox:

"I have been working on a low(ish) cost (cf. DB6NT) low-power transverter
for 10GHz using modern technology. This is being designed to cover any LOS
path in Europe with some margin with a 20dB horn or maybe 15in dish and to be
easily upgradable to something more potent.

I’ll probably bring this out as an assembled and tested PCB ‘kit’ towards the
end of the year."

Apparently the price is likely to be <£200 and SOTA is seen as a potential market. Add-ons will include a horn antenna with waveguide transition so there will be nothing difficult to make. I’m guessing that it will be FT817 compatible with RF switching too (2m IF).

Might anyone here be interested in such a device? It could be a lot of fun!

Maybe … but if we used the FT817 to drive the 3cm transverter, what would we use for 2m talk-back?

In reply to G3NYY:

The 817. You drive the transverter from the 70cms output on your 817 and connect it to one of the 817 antenna sockets and use the other socket for 2m.

Using 70cms for the IF makes filtering easier. It’s easy to filter out the unwanted components if they are 432MHz from your LO than when they are 144MHz away.

LoS paths - just use a handy?

I am sure my correspondent would welcome suggestions here as to what we might like…
