If those are tx on/off figures, I would take the widest range i.e 3.29/1.62

On my RP8D1 I have 2.11/0.77 and works fine

ok thanks I'll give it a shot and see what happens. oh btw, I have a 10K resistor with a 5% tolerance. Actual resistance is 9.9K... think that will be ok? Or should I find a 1% resistor?

thanks

ash

Is ok
Also, do a range check (with antenna collapsed) and see if the voltage variation is liniar between 3.29 and 1.62V, or there is a trigger behaviour, i.e. it jumps abruptly at a given signal level. Is useful to have this info to know how to react in flight.

This is s two boards receiver, right ?
I am afraid the FM chip is one of the inner sides, hard to investigate...
I would probe the two groups of three pins that connects the two boards together, last picture, bottom side, left and right

Seems to bee the very same board!! Confirm ?

Can't swear they are identical, but... very close.
Anyway, probing that pad doesn't hurt at all !

Measure the voltage between that pad and ground, should have a significant difference when Tx is on or off. Quoting Sander: "This will output a voltage between 0.7 and 2.2V, with 0.7V being the absence of any signal and 2.2V with the transmitter nearby "

If you ask this here, then you didn't read the whole thread.
