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 all

Revised version of TRV

One amplifier from TX has been deleted (TQP3M9009 removed).

PA (SKY66292-11) has a max input of 8dBm and ATT had to be used.

SWR and PA measurement lines were added.

Now high SWR takes off 4.5V supply from uPC2709 driver and blocks SKY66292-11 pin 6.

The PA measurement line is amplified by a transistor and controls the LED (you can connect an analog meter).
