Dear all,

I needed to open that topic, because:

• that topic was missed in the forum
• I might not be the only one with that issue
• and it is always good to get new opinions

As I thought, all of your very helpful feedback is now giving me the confidence I was looking for. And I was right up to here with my ideas.

Thanks, Volker, Mike, Johannes, Wilfried and Ed !

It is like in real life.... Focus always focus I will work on that. Now the duty for the very hot afternoon will not be hocus pocus, no it will be focus POTY.

And yes the dielectrical lens is not installed right on purpose.

Even the correctly installed lens is giving a gain of about 1-2 db. This is what my tests were showing.

So here my ToDos:

• Finding the dish focus for the POTY.
• Will it be the entrance of the 10GHz feed horn - the dielectric lens/beginning of the copper pipe?

Stay tuned for my reports.

Thanks for now. 72/3 de DM5TU - sTef

Hey all,

I mounted my RX-TX (Diavolo Twin LNB and POTY) combination in my 80cm offset dish today.

The RX signal strength of the CW beacon with that RX-TX combination is about -84 db.

The RX signal strength with just the RX LNB mounted is about -76db at the CW beacon. So there is a loss from about 6-7 db with the POTY mounted.

Unfortunately mechanical wise I can not push the 10GHz feedhorn more further to the back due to the LNB mount.

Is anybody having the same issue and how did you overcome that signal loss?

• Different LNB mount?

Thanks for your thoughts and suggestions.

Hi all togehter,

OM Serge, UT5JCW is totally sold out of RX converters.

New converters are expected by the end of June 2019.

ISSUE FIXED - Software drift control nw working

Dear Flo,

this is how it should look like I guess.

See the picture, please.

TNX fer ur hlp, Flo !!

Now it is getting forward..

You have to dial in the f=10.489.800.000 Hz...

Because the IF was set in the options I have expected the software to do this automatically.

There is a mind gap in the instructions.

So we step ahead now.

See the picture

Hi Flo,

thanks for your reply.

No luck.

Please see the pictures. All actions marked in yellow.

Were these your recommended settings?

No waterfall on drift controll using the internal Geostationary Satellite Beacon add in

Hi everybody,

I am trying to use the drift correction in SDR Console without any luck.

The setup up is as follows:

• SDR Console V 3.0.9
  
• SDRPlay DUO
• The geostationary satellite beacon add in is activatied inside SDR Console

Following the step by step console configuration described by Simon, G4ELI on his website, I am not seeing any waterfall of the upper beacon.

Could it be that this is caused because my RX f in SDR Console is 739.850 MHZ instead on the expected f of 10.489.800.000 Hz?

I already put in the converter offset as Down 9.750.000.000 but the f is not been adapted inside the SDR Console software.

Can someone please give me some ideas what to do to get it working?

Plase see the attached pictures.

Hi Achim,

this is what I like most. A minimalistic approach. Could you please give me an info oon how you powered the Golden Media GM-201 LNB? Did you use a power upconverter? If yes which one did you use.

Thanks a lot from sTef (Stefan) DM5TU ..... as you a paragliding ham.... happy landings es 73/72
