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"

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
DK1ML danke, Du meinst direkt am LNB? Aber dann bräuchte ich doch einen Dämpfer am Eingang? Wieviel dB müßte der denn hBen?
-
DK1ML
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.

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?

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.

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
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.

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