Hello Steinar,

 

TKS for the information. So you pertain to the small “club” of the C band listeners

Could you remind us the diameter of your dish. Moreover, the LNBF does not seem to be a C1W-PLL, is it?

Hi Patrick

Yes it is a C1W-PLL lnb, but not the lite version.

The dish is 1.8 m in diameter, focal Length 67,50 cm

Thanks Steinar for the information. So I note "1.8m" for 4A-F4 (it would be worst...)

Hallo, Steinar !
Could you tell me-us at which frequencies you currently receive on the downward link position reports ?
Please the "plain" frequencies, not the "downscaled" ones you previously showed.
You showed 7,xxxx but this is downscaled - what I would need is the plain frequencies, i.e. e.g. 1526.078, 1526.108.
This refers to alphasat 25E.
I found the latter mentioned somewhere
as being used - do YOU currently use them as well ?
What are Your current ones, please ?
Thanks in advance,.
Good spotting,
Regards,
Roland

Hallo,
Thanks for your latest info.
Could you convert-translate your frequ - 7xxxxxsomething- into the USB frequ --- 1526xxx --   I need for my SDR# 
and tell me ?
Thanks in advance,
Regards,
Roland

Hi

Because I am using AirSpy as an SDR , I am only using multipsk to decode
with I/Q interface via the sound card. The 7019.910 has nothing to do
with the freq from the satellite.

There is a strong beacon on 1.199 GHz (5.150GHz - 3.951GHz(the actual
beacon freq) )

I am using this freq 1.526.000 GHz to RX AERO (5.150GHz - 3.624GHz)

I hope this will help you
