Ah, an FT-790R 
I have one of those (and an FT-290R) in the "junkbox". Used it on OSCAR-10 and -13 (with home-made amp). There even exists a video (very bad quality) of our fieldday in 1985 where it was used
Now I am using an FT-817ND as part of the station for QO-100.
again...amazing

Why all the others need dishes ?
Why all the others need dishes ?
I did not try this yet (will try later today) but I was kind of expecting it because of the very strong signal via the dish.
However, I guess for optimal receive performance you need a small dish, maybe 30cm, at least.
Also remember that the usage is now quite low. When the entire transponder is populated like a HF band the power available to a single QSO decreases.
(even worse when the transponder goes into AGC due to that)
What is the app he uses on the phone for the rtl-sdr in this video https://www.hamdigitaal.nl/author/pa3pm/
@Mike5000 , I will ask him tomorrow when I see him. But I think it's the mobile app from websdr.org.
This was not done by Peter PA3PM, he only posted the video on his website.
The maker of the video is Oli SQ3SWF.
I think he is on the forum as well, but at least he is on Twitter.
Ah, ok ... didn't knew that
