        I realized when I sent that that these days VLF meant different
things
to different guys.  Answer is 160-190 kHz band which used to be "VLF" to
many of us.

        PSK10 is a program by F6CTE; K7RR sent me the zipped program and I
can't remember where he got it.  Appears to be a slow version of PSK31,
but we're not quite sure and I haven't had a chance to query Patrick
about it yet.  For us the advantage of PSK is that we can use our beacon
transmitters almost "as is" - just adding a biphase modulator.  There is
a somewhat later program called MultiPSK which includes PSK10 but is
more flexible.  I've downloaded that from

        www.qsl.net/wm2u/link_modes.html

(hope I typed that right as I'm typing on my Mac and looking over my
shoulder at the PC).  Patrick's instructions are his translation into
English of ones written in French (his English is better than my French
is these days), and I've had a problem trying to pick through them.  I
suspect a little careful reading will help.

        Our current plans are to try things out on 80 meters and then go on
down to 180 kHz.

        I realize most of you are "into" much slower modes and are getting
great results but we're far enough "out west" that copy of any of you is
doubtful in our noisy locations and we just want to have a go at a
little communicating.  Been through straight CW (normal speeds), SSB,
and coherent CW and looking for something a bit different.
