Hello James and the group,
what you all think about the best method of generating multiple, sequential
frequencies from an LF transmitter? The parallel port method, just suggested by
Jim Moritz, or a sine signal generated by the sound card ? Or maybe another,
simpler, method ? Just asking, as you all have much greater experience than
I have on putting together an LF TX. Thanks for any reply.

P.S. Which is more correct in English : "thanks for any reply" or "thanks for
any replies" ?? The two forms seem to be both used...
