Alexander,
Good news! Just want to mention, the diode will drop 0.7V across it in this application. This is the reason the FET is used since it has a lower voltage drop across it.?
This is will contribute to the lower current draw in Transmit (0.69 A). It's lower than what's usually seen.
I built my QDX for 9V operation. In transmit I read ~0.97 A and in receive it draws 0.14 A.?
Do you have a way to measure transmit power out in Watts into a 50 Ohm (dummy) load? I'm just wondering if maybe one of the PA FETs (BS170's) is open and giving you the lower current reading. I don't want to be an alarmist, but it's something to consider.
