Hi Murray,
Welcome to the group ...
About I/Q-exciters for LF:
Here is a VERY ugly one (mine ;-)
http://people.freenet.de/dl4yhf/phasing_lf_exciter/index.html
And here is a much nicer one:

Some of the LF-specific software bundles (Jason, SpecLab) provide the
necessary I/Q outputs to send CW, QRSS, HELL, PSK31, etc already.
Best regards,
Wolf DL4YHF .

Is anybody doing any work with Kahn Envelope Elimination and
Restoration technology on LF? It would be especially applicable to
those of us with nonlinear LF transmitters (class C, D, E) wishing to
run sound card based modes (and even SSB).
I'm especially interested to know about any sound card to LF carrier
and amplitude exciter designs or converters, or I and Q converters.
