To get a specific SNR with known EIRP tells us what the satellite G/T is. Unfortunately I do not know what the SR bandwidth is in SDR Console but luckily I did some spectrum analyser measurements recently.

The beauty of this is I can go back and do analysis on the data.

Hi Mike & all,

Maybe we can ask Simon G4ELI, how does the software work in this regard.
On the latest release 3.0.13

he added a few niceties, notably an analog S-Meter, wich he describes here:

PA3FYM,

Yeah, I've been following your project.
Sure it's a really beautiful work.

PM me with price and availability.
I have not enough technical skills or equipment to embark on this kind of builds, but can really appreciate other people's work.

Hi David G0MRF,

Many thanks for tour input.
I was thinking of using it as a pre-amp for Pluto.

But, as you mentioned, Minicircuits has a wide range of cheaper and more efficient devices.
The box is really nice, though.

Hello everybody,

Being a newby at microwave stuff, may I ask your opinion on a
Avantek Amplifier AFT-4231, 2-4 GHz
Datasheet attached and some more info on:

DB2OS, well that is some piece of history.
Maybe it is time to repeat that kind of action, not in Germany this time, but in some other countries.

Here in Portugal, we've managed to congregate some 26 local clubs and associations, and present to Anacom (our BNetzA) a document with our points of view in regard to the French proposal.
Anacom, has declared on a meeting on the 15th July that they will vote against the inclusion of the french proposal to the Agenda.

Never the less, and in face of the last developments, yesterday, the group of 26, issued a new document to be presented not only to Anacom, but also to the Ministry of Foreign Affairs and to the State Secretary of Communication, wich have the voting power on CEPT and ITU meetings.

I've just read Germany's view on the subject and it is a very good presentation of the possible mutual interference.

Hi everybody

I've just read this thread, and with my 60cm dish I've managed to achieve MER 5.5/5.6, but today it has reached 5.9/6.0.
Hardware is MiniTiouner-Express
60cm offset dish
LNB Octagon Green

This article I published around 20 years ago.

Don't have it anymore (because the server -at that time- doesn't exist anymore) but somebody saved it for later use.

Still is a reference for me.
My first wifi antenna was based on your article.

Friday is my free day, so time to hobby! As guinea pig #2 built the 'Radioclub 't Gooi' (PI4RCG) MMIC amplifier however, deviated a little from the original design (didn't had all the parts, so the junkbox is always my best friend ; -) and used two TQP3M9009's as driver MMIC's (original design uses two SBB3089z's). My MMICs have more gain and hopefully all will be stable! Amp has to be tested of course.

Below a pic of WIP (Work In Progress) (click to enlarge)

That looks very promising.

Congrats.

Hi.
I've attached a spreadsheet vith the data above, plus the information relative to Portugal.

Hope it provides a good working base.

Hi,

In the above screenshots what was the bandwidth selected?
You must have bigger than 2.4MHz bw in order to see the Wideband spectrum signals.
The attached screencaptures were taken with a similar setup 60cm dish, Octagon Green LNB, ADALM Pluto 8MHz BW and SDR-Console.

Hi and thanks for your work on this project.

Are you considering to add support for the ADALM PLUTO as well?

Thanks

Sal
