Having had to modify a 137kHz source to be able to generate on-off
keying, I'm transmitting a signal using 2.048s symbol mode on 137420Hz
33% duty cycle (for now)

This is based around my PIC generator for the mode
Details at   http://www.g4jnt.com/PIC_Opera_Source.pdf  and
http://www.g4jnt.com/OperaBeacon.zip

As its an independent source, with no PC in the Tx chain - no IP
packets will be sent to t'web showing the details

and its definitely gettign out....

15:46 136 G8IMR de F6CNI Op8 391 km -28 dB in 136 kHz dial nr Paris
