or you can try to build the Wintehill receiver: 4 channels at the same time!

hi Dominique F1EJP ,
is it possible to have a copy of your new/beta "Datv-Easy for Windows" as I have a spare LimeSDR mini I would like to use for DATV.
thanks!

I have a question:
considering that both signals are DVB-S2, which one has the best "shape"? and why?

btw I was able to recover at least the page with some explanations, even if it's in Russian!

the attached .pdf is the page with the "PHASE NOISE SPECIFICATION" DC7KG is talking about (taken from the AD UG-570 doc: ez.analog.com/cfs-file/__key/telligent-evolution-components-attachments/00-441-00-00-00-07-91-97/AD9361_5F00_Reference_5F00_Manual_5F00_UG_2D00_570.pdf ).
it will be quite difficult to find a TCXO or an OCXO with those specs.
that's probably the reason why AD engineers chose a crystal oscillator???
BTW I found this one by ABRACON: AST3TQ-40.000MHZ-5.
unfortunately it seems no longer in production and, more over, it's quite expensive: some 50€...

you can try to join this "group.io" and ask there:

well...if a "digital" PTT is not available then let's go analogue!
-
I see...but that is beyond my capabilities as it probably means that I have to modify the software somewhere!

is there a way to control an external changeover relay in case I want to do iso-frequency traffic and don't want to receive myself?

hey Roberto:
HOT stuff!!!
-
that's very interesting!
-
sometimes the "WayBackMachine" is better...
-
now the beacon seems OK with the LAV decoder!
I will try later with other decoders...
