Display MoreHi Bert,
I use Airspy R2 SDR, SSB SP-200 Preamp and ANjo Eggbeater.
It's only a very simple setup at the moment to run the SatNogs software, but it works very well to see what's going on in the 2m satellite band.

The signals recorded on your station's SATNOGS are strong. Impressive for a simple Eggbeater. Very good signals.

Tnx Marcel !

This week i saw an interesting project to adjust (screw) the LNB:

This is a part 3 this article "Low cost 10Ghz EME Rx".

Display MoreHi, das im Pluto auch 3,3V zu finden sind hab ich mittlerweile auch bemerkt.
Den verwendeten Regler hab ich in anderen Projekten schon erfolgreich verwendet, und deswegen nicht lange gesucht. Die 5V zweige ich schon sehr früh an D3 ab, direkt am USB Eingang. So bin ich bezgl. der Stabilität der 3v3 zumindest sicher (hängt ja auch die Abstimmspannung dran).Als VTCXO habe ich diesen:

verwendet.

TTEAMCJANF-40.000000 Output Level (Clipped Sine Wave) only 0.8 Vp-p.

3v3 is possiblible at U15. I dont know what currente supply is possible.

Unfortunately here dont have fleamarket with SSPA! I thinks in the future is possible. I buy some things of others countries.

Great !

Display MoreHello Wolfgang,
Thanks.I have updated my description about the MHL21336 amplifier at www.dd1us.de
Kind regards
Matthias
Hi Matthias DD1US .
I made this amplifier using your schematic. I bought the module in september 2019 (Ebay) but i assembly this week. My module isnt counterfait. I supply with 28v in both pins and i have approximately 2 until 3 watts ( sorry, but i dont have how calibrate measurement equipment ).

This topic is about translate 0.8Vpp TCXO output clock to 1.8V CMOS level input :

But i will try use MMic too.

So Mic,
habe die Schaltung etwas verbessert und bekomme hinter den MSA jetzt 1,5 VPP raus und musste noch einen Spannungsteiler dahinter machen. Jetzt habe ich 1,3 VPP.
Hi !
C8 = 100 pF and C10 = 100 nF ?
I thought that C10 the value is too high.
Tnx !

Some info:
"These modules in turn utilise detectors such as the D8318 device from Analog Devices....

I took the old one out and added an IPX connector instead. Allows for external reference input of whatever frequency.
Clean solution.

Hello together, hello Hans-Michael,
look also at https://dd0yr.de/Bilder/13cm-PA/13cmPowerPa.pdf .

Great !

sorry I don't understand 000,000 frequency ???
Yes.
If I tune WB Beacon 742.600 mhz and restart dvb-s gui and start over, the screen will display 000.000, but I tune the last frequency (742.600). Why ? I dont know !
-
Tested with Adalm Pluto the WB Beacon and 90cm dish.
Tnx !

G0MJW: 8PSK modcodes are not supported in version 2.0.10. They were first introduced in version 2.0.12
But you are right about the UI Design. Many Laptops have 1366x768 as a resolution, but the window is about 947 pixels high. I'll try to move some stuff around and clean things up. Never thought about high DPI displays. I'll also address this problem soon.
I'll release a new version (2.0.13) today with a few fixes. In summary these are: 8PSK short frame support, GUI cleanups (and new tooltips), and support for offset tuning by clicking the right mouse button. There is also an overlay showing transponder bandwidth requested by DB8TF.
There is also a 100% performance update for FIR filtering (atleast on my CPU). These two changes will be useful for future extensions like multi transponder decoding.
Tnx SWL - markro92 !
