You registered as SWL and so it seems that you don't have a valid license to TX.

If that is wrong and you have a lic then please change your nick to your call.

Maybe then you get an answer.

Still here:

Warum nur bis 23.Juni?

Üblicherweise geht das doch immer bis 31.12.

Gibt es da Gründe?

The sat-dealers don't know what is inside the LNBs. That's a pity.

Take a 12V battery, connect it to a unknown LNB and place a scanner near searching 25 & 27MHz .

If it is a PLL LNB you will find the 25 or 27MHz signal. If there is no signal its an DRO LNB.

I have checked many LNBs that way in our local stores "OBI, Globus Baumarkt/Euronics/Expert..." without any problems by the staff

Sieht ähnlich den Aaeon Boards aus mit den ich im letzten QRL beschäftigt war.

Der typische PC104 Anschluß ist da auf dem Board zu erkennen.

Dort hatten wir Adaptermodule für Speicher-/WLAN und PSU aufgesteckt.

Maybe a BU500 helps?

RE: BU500 UpConverter by HiDes Taiwan

HiDes hat gerade eine neue verbesserte BU500 Version gebaut.
Durch Kundenfeedback ist eine neue Version dazu gekommen.
Benützer bekommt Möglichkeit leichter zwischen TCXO und GPS zu schalten,
sonnst ist alles anderes gleich wie bei version7.
Gleichzeitig wurde mir mitgeteilt das die bereits in EU befindliche " v7 Restposten" von HamRadio2019
zu ein günstigeren Preis angeboten werden. Preise sobald ich es erfahren werde....



HiDes has just built a new improved BU500 version.

Frag mal Gerrit, DF8JO

Er hat vor längerer Zeit mit solchen Antennen herumprobiert.

Hello. I am pleased announce that the problem has been solved. I changed the polarization of the LNB by changing the supply voltage.

i asked you many days ago if you have switched your polarisation:

RE: Software DVB-S demodulator

Have you switched the RX polarization ?

Seams like your RX signal is to weak.

On the NB you have a system noise of S5,8 > 34,8dB

The lower Beacon has S9+13 > 67dB

So your Beacon SNR is abt 32,2 dB

On my dish (120cm) the lower beacon has 40-41dB SNR (depending on the Console BW)

Zoom out of the NB (2,4MHZ BW) and look if you can see the TP shoulders.

I think the problem can be solved by replacing the sdr receiver. I would to know: what brand and model of usb sdr receiver are you using? Thank you

Your sdr receiver is sure not the problem! I use the exact same type here

no problem here with an even older RTL-SDR Stick.

Have you switched the RX polarization ?

In the "Filter" Tab on the left you can set and modify the RX Bandpass
