Sound's like: ignore problem and problem will gone.
Yes, we should not publish all this kind of info on twitter, facebook, youtube etc, but it must stay on forum for internal use.
I think, that pirate tx info can be saved so everyone can learn from it how not to be a pig and what not to do. Bad history is also a history.
For next generation amateur transponder it is good idea somehow get location from satellite. I don't know hot it is working, but there are rumours that that on commercial DSNG uplinks, satellite operator (SES, Eutelsat) can locate transmitter within 1 KM precision.
"I have a dream" (In memoriam of Martin Luther King Jr.).
I have a dream that I will build GPSDO:
And build Si5153c synthesizer:
DD4YR, I really understand you. I had similar problem with quattro. For now I will stay with Twin PLL LNB with DIY hole for external clock in cox cable.
But... Aliexpress could be promising. I'll give a try.
Some time ago I purchased AX technology Opticum Twin Black Buster LNB.
Absolutely different internals compared to Quattro LNB. I don't have PCB picture, but it looks 90% like this Octagon OTSLO 1609 LNB, except tah Opticum don't have 10.7-12.75 GHz BPF and different PSU doide case, so I hope it will work nicely on 10.49 GHz. So this LNB will be starting point for P4A NB and WB.
Yesterday I purchased AX techologies Black Buster Quattro and I am really sad.
I wanted Quad, but quattro is OK. Duad delivery on every output enythig what you ask (by manipulating polalry voltage and tone). Quattro deliver on every output own signal: Hor-Low, Hor-High, Vert-Low, Vert-High. so, need to connect sdr and minitouner to correct output and unused (high band) connectors can be used for LNB supply and Ext Ref clk in.
The biggest problems it that this LNB don't have PLL and quatz. They are using ceramic oscillators. So no ext ref clk in possible. We careful before purchasing LNBs.
Here are few pictures of my problem. Be smart and don't make my mistakes.
Another idea for monitoring: BATC will provide webSDR, so you can always monitor downlink from webSDR.
BTW, can LEILA play audio file instead of siren tone on "problematic channel"?
If it is possible, than some automatic software can generate and send FT8 QRP message automatically.
And on SSB channel LEILA can play some audio MEME from Tarantino movie.
If on your SSB "channel" is LEILA-2 alarms and you are absolutely sure that your TX power is OK, or there is indication that other party use too much power, send him/her QRP.
It is interesting what will happen on FT8 "channel". Maybe next WSJT-X versin will have following automatic feature: When you see your call and QRP your software automatically decrease volume by 3dB. It is like this:
1. somebody send: "CA1LL QRP"
2. WSJT-X, who have CA1LL, automatically decrease audio out volume by 3 dB.
But there is possibility to to hijack and remotely make somebody "silent".
P4A will be really interesting new experience.
It would be interesting if Nitin [VU3TYG] from MK83tb can receive Es'Hail-2 beacon. It is worth to try.
According to Daniel Estévez ea4gpz Twitter https://twitter.com/ea4gpz
Es'Hail-2 beacon still transmit but power is reduced by 25 dB.
Another Interesting observation:
Es'HailSat homepage have coverage maps and non of them have beams to Europe.
So, in theory maybe MELCO/Es'HailSat engineers are already using P4A antenna for beacon and IoT tests.
TLE data are 10+ days old, so Orbitron, n2yo etc sat tracking software have old data.
I solved this problem with some help from China. My setup for TX:
HackRF or LimeSDR
Amplifier module with max output power 100 mW. Transistor can be changed to something else form farnell.
WiFi booster with max output 4W
Spectrian amplifier 75W
