Hi all,
To expand the question from Trevor.
Is there maybe a list with (roughly) indications for the SNR what we can expect for a particular antenna size?

Thanks Roberto and Evariste for the fantasic job you guys are doing.
Maybe you can add also the Amsat-DL down-up transveter in the "Transverter OL" list, we are here on the Amsat forum.......

Is it not wise to ask PE1RKI, he makes those things.

Hallo Markus
Habe auch den TS2000 (seit mehr als 15 jahre), aber Leistungsspitzen habe ich noch nicht bemerkt (oder von gehört / gelesen).
Der 13cm SG-Lab Transverter ist eine schönes product aber leider nur eien IF (432MHz) fur rx und tx.
So kann man nicht full duplex arbeiten und der TS 2000 in SAT mode gebruachen, that's a pity.
Ich arbeite mit dem amsat.dl downconverter (das erste modell) auf 144MHz und ein homemade Upconverter mit IF auf 23cm in SAT mode.

Hello Peter,
Are you willing to tell what kind of equipment your using, antenna, pre-amp receiver .........

Thanks for the info Lucio.
It looks that the video runs much smoother with VLC.
Is it also possible to switch off the Minitiouner audio en video stream and use only VLC?

Hi Nicolas,
I can say nothing about your 30 dB signal-to-noise ratioBut keep in mind that the Goonhilly SDR uses a much bigger antenna, 1.3Meter.

Danke Matthias,
This is my modified LNB.
For the whole construction LNB/sat-dish see my homepage

Hi all,
Just installed a new dish-antenna, prime focus 180cm.
The beacon give me a MER of 11.4 on this moment.
Now is my question is this a good value for my dish-antenna?
I have no reference so no way to check that number.
But what is MER, how is that calculated?
Means 3dB MER more also double the power, same as by a HF-amplifier

Peter, vielen Dank für die Information.

Hallo,
Nur aus Neugier.
Warum wurde für den DATV-Modus eine Frequenz von 833 MHz ausgewählt?

Indeed the "lastqrg" is the problem.
Did put a newly downloaded "Raspbian Buster Lite" on the sd-card installed everything again with the same result.
( The ./build_RTLSDR works perfectly i did it after the ./build_SDRplay error.)

dj0abr Kurt can you give me a clue on this error
( The ./build_RTLSDR works perfect and a nice WebSDR in my browser, but with the ./build_SDRplay it is generating a error )

DB2OS, or some else who can give a answer.
The question may not belong here but I was curious.
What kind of equipment is used for the NB / WB uplink transmitter probably not a Pluto and/or Portsdown......
Or is there a link with more info about the used equipment/antenna used power and so on.

New pictures I had never seen this before.
With good reception.
