includes frequency modulation ??
Only if the vfo drifts hihi
Opera is a single tone ON-OFF keyed signal - true data mode , the
only one that can be sent via a CW
tx
Decoder has AFC , so Tx/Rx are able to drift , within limits
Good Luck - 73 - G,

Bob,
Rob Moore at the University of Florida has a wide network of VLF receivers
in continuous operation. He would like to look for your signal tonight. I
told him you'd be on 29499.0, is that correct? I think I see your signal
in
Paul's grabber (at 29499.0), but I'm not clear on whether OPDS 2H includes
frequency modulation, and it would be helpful for Rob to know that.

Bob,
I wont be on tonight. Antenna is still tuned on 33.9, it's 0 deg C and
drizzling rain. Hamfest tomorrow and Saturday so it may be Sunday before
I'm back on. I'll be watching your Opera reports. I'm sure there will be
many. GL
