DL2FP , you may be NEW on the transponder. F-stns are operating since the very beginning just out of the guard band. So no confusion about this +
Dear Colleagues, please help - how to Log In chat room on QO-100 WB monitor web-site? I have tried to type '/RK3DJW_Andrey', but nothing happens - it doesn't register me..
Hello All
I think to change my common pigtail cable against one with a RG-316 cable with a length of 15cm between up-converter and ("8W") WiFi booster. I thought RG-316 has less loss. Now I have calculated the dB losses between RG-174 and RG-316 on https://www.timesmicrowave.com/Calculator . The losses are the same for this short length. Any comment is very appreciated.

Yes Thomas, but the 4W version needs one!
OK, I measured the temperature outside. It rose 4 degrees after a hour of operation. But it was a "Handgelenk mal Pi" measurement with a little thermometer.

Thomas, I observed the same with the "4Watt" version I borrowed. Even during SSB. After mounting it on a big heatsink I had no problems.
Hallo Mike
The "4Watt" version has no heatsink, but the "EP-AB003" has one. See
http://www.szedup.com/products…-expansion/wi-fi-booster/
But for continious signal operation the heatsink may be too small. Thanks for your observation.
During QSO's I observe my signal on the Goonhilly WebSDR. If I send a long duration CW-signal it drops down after a short while. I think because of overheating. After a break the signal is OK again. In SSB I have no problems with this booster. But I think for digital modes this booster is not suitable with small dishes.

There is no chalenge to hear WebSDR, but its one to build its own "downlink". You are SWL - Why ? You could listen Web-Radio instead. WebSDR is good and OK to control its own transmitted signal.
I wish you good luck by your setup and future HAM license.

We had our QSO at 27.9. Is QSL via bureau OK ? I love paper cards !
Oh, I misstyped. Not SSTV, I meant SSB. Anyway, then I will not send a card which will be returned. I wish good work by your projects.
Dear AMSAT-UK colleagues
Since April there was no report about ESEO. Until and before April I'm informed about the issiues. Is ESEO lost ?

Hi, operational now at KG-STV, WinLink and FreeDV. Tx on FreeDV must be improved.

Hallo Wolfgang
I read every day about problems with "Windoof" 10 updates. May this platform help you.

If emergency traffic is active, write it here in the Shoutbox with QRG and "... emergency pse keep QRG free !" or something like that.

In principle you are right, but QO-100 is "only" a HAM-transponder on a multi million dollar satellite. I think nobody expected these problems.
Is LEILA being implemented the same way as on AO-40 with an audible warning?
No, LEILA2 is an autonomous TRX in the command station. But the technique is the same, I think. The audible warning has to be adjusted now. I found only this article on the homepage with the keyword.

HB9SKA nice idea.. but there must be someone to check if this is possible to implement and then to to this. all are voluntiers with only limited time. First we should reduce the LEILA level and see if this works or not. Then we can think about doing improvements.
OK, Heiner, I agree. But it must be done something in the near future, otherwise we will lose credits in Qatar. Or am I impatient ?
We can not defend ourselves against pirates and psychopaths, there remains only
to switch off the transponder. But that can not be and we do not want that. So
the pirates would have won her psycho game.
If kids are not allowed to do something, we have to educate them. I always read
again, "I have never heard LEILA". But with our SDR receiver we could see LEILA
if LEILA were visible.
My suggestion, modulate LEILA with e.g. Hellschreiber. It would look like this:
L
E
I
L
A
!
P
S
E
!
Q
R
P
!
and set it not over but next to a QRO-signal. I hope this helps.
