DD0KP Heiner, I don't what your link really is but it does not seem to be live... the videos are awesome, but obviously "fake live"

H. 17.30z - What is digital signal at 10.489.570 ?

DO5MSH Dämpfer nicht nötig (warum denn?), aber ein Bias Tee um die 12-14V an das LNB aber /nicht/ an den Pluto zu bringen. https://tinyurl.com/y78t46jn
DO5MSH Wednesday, 5:06 pm

DK1ML danke, Du meinst direkt am LNB? Aber dann bräuchte ich doch einen Dämpfer am Eingang? Wieviel dB müßte der denn hBen?
DK1ML Wednesday, 11:51 am

DO5MSH Der Pluto kann doch direkt auf die Frequenzen, dazu brauchst Du keinen Up- oder Downconverter. Zur Ansteuerung des AMSAT Upconverters müsste ein 30dB Treiber her. Lieber neues Pluto Setup mit PA aufbauen.
DO5MSH Wednesday, 11:17 am

Moin, Anfängerfrage: Ich möchte einen PlutoSDR in das Ensemble AMSAT-Downconverter V3d & AMSAT-Upconverter UpCon6W integrieren. Brauche i h (was) dafür ein Dämpfungsglied und / oder. orverstärker?

Please look at the post. Thank you.

Ok the reception at 2.400 mhz but immediately after the spectrum does not display any RF signal in the air! Rye broadcast locally with another Pluto.

Hi everyone ... Has anyone tried to receive over 2,400 MHz with DVBS Demod GUI?

No matter how many times I exit, store, save, that configuration box is not there and checking the rotor setup, the N or the S is gone. How do I fix please? TU Frank
NG1I Jun 26th 2020

Hello....I am having great troubles try to set up the rotor. I choose the correct interface (Yaesu 232) and then type in N or S as the help box directs. I then exit and no setup box to configure the correct com port and baud rate.

And I mange mi technecal part well but just only Class E So that was not covered in detail
DO1OHB Jun 25th 2020

DK1ML , why had the British Amateur Television Club on his page/forum a PCB with such a 50 to 75 Ohm adaption https://forum.batc.org.uk/view…=15&t=3122&p=17416#p17343 ? Did I misinterpret something?
DK1ML Jun 25th 2020

DO1OHB How did you manage the technical part of your license? For reception it makes no difference, if you use 75 or 50 ohms. The impedance is only reactance, not real resistance.
DO1OHB Jun 25th 2020

DD0KP, behind the BIAS is still 75Ohm Impedance, due I need a Impedance adaption 75 Ohm to 50 Ohm? If yes how?
