Hm...
I don't know what to answer.
I am not making this publication for sales.
I want it to be an aspiration for other builders.
It is listed on ebay. Just type search: QO-100

Hi guys
TRV can work with a 2m or 10m TRX.
Includes one SAW filter (SF2126E) for reception and three SAW filters (SF2124E) for transmitter, ADE-25M double-balanced mixer. Output power: 3.6W (SKY66292-11). VCOCXO 10MHz generator. Size 8x5x2cm. Supply voltage: 12-13V, curent: 300mA (RX), 1200mA (TX).

Hi
I received: 3.2W with 1xSKY and 6W with 2xSKY.
SKY66292-11 are better than YP242034.
You can buy SKY chips cheaply on Aliexpress:

Hi
Aluminium case PA im Oxid ist ein Isolator!
Sie benötigen Schleifpapier, um das oxidierte Aluminium auf der Oberfläche des gesamten inneren Teils der befestigten Leiterplatte PCB PA von der Verbindung abzuschleifen.

Tony and what does the signal from the GPSDO generator at 10GHz look like?
1) Set the frequency on the GPSDO: 25,780.770MHz
2) Connect the GPSDO generator signal (25,780.770MHz) to the LNB
3) Connect the LNB to the QO-100 and to the TRX at 435,000.000MHz
Will the tone of morse signal be clear (ta ti ti ta)?

Hi
Very good project. I have a question if such a generator at 25MHz does not dance when duplicating 390x. The reference frequency is 1Hz this is very low.
Look RX QO100 (this is alternative type GPSDO project): https://www.youtube.com/watch?v=Kye-K_7yC40

Hi
Thank you for a good review. I bought BLP9G0722-20G in China at $ 9/piece. They will sell me the original transistors:

I now change the design and put in a new housing like my TRV. Now you can make 12V power supply because there is a step up converter with potentiometer regulating from 12V to 30V.

Hallo Urlich
Können Sie zeigen, wie Sie den Filter montieren.
Entweder Sie löten den mittleren Stift und können dann die Röhre nicht einsetzen
Oder Sie setzen das Rohr ein und können den Dorn nicht anlöten.

Hi
Vielleicht ist es besser, 2x SKY66292 durch Transistoren zu ersetzen 2x LD-MOSFET PD85004 ?

OK Mike you're right.
Additional photos.
Measured Antennas: POTY has old measurement SWR: 1.35 and new measurement SWR: 1.02! This is not a scam. The old POTY aerial measurements had condensed water vapor (temperature difference) when taking the measurement:
and receiving signal and receiving without signal. (LNB for "POTY": +11dBm, LNB for "Helix": +14dBm) -> including TRV no new TRX calibration "dBm"
