Hello Warren,
I have also a Ropex and will scan the light documentation for you.
The only modification I did was a socket for the xtal, so I can easily change
the frequency. I have anyway the top cover removed, because with an additional
big fan I can ran QRSS60. Without I think QRSS3 is the maximum.
I also need a low pass filter in front off my loading coil as described on the
great website http://wireless.org.uk/ropex.htm

Betreff: LF: Ropex Info?
Hello the list,
I have just acquired a Ropex "The First" transmitter for 136kHz -
but without documentation of any kind.
I know that Ropex did not supply anything more than a single sheet of
instructions but I'm lacking even that.
Questions:
1) Anyone have a copy of the instruction sheet that they could copy or scan?
2) Any info on mods (injecting an external vfo for example)?
3) Anybody do any 'reverse engineering' of the circuit?
Any info at all is much appreciated!
