I need to get back on CW - been off for a couple of weeks.

Oh, it can't be -that- bad, Rob

There's supposedly a 'late-night' group that gets on down around this area of 
the Country at about midnight or so, local time.  May wanna give that a shot. 
 I might even try to get on, myself.

yeah, but I've decided to go a different way, now.
Since the "solid state audio driver" circuit (reference 
http://www.qsl.net/wa5bxo/driver1.html) is contained in an aluminum chassis, 
I've decided to go ahead and mount the tube sockets on top of -it-, and I've 
got another chassis that can hold the modulation transformer as well as the 
filament transformers.
A friend is comming by today with another small cabinet, that should be able 
to hold both chassis.  I'll just set the modulator power supply (a converted 
SB-221) on top of the chassis, and be done with it .

Don't know the conversion formula from km to miles, but lessee, if 64mph is 
100kmh, that would make 200km 128m, and 192 miles would be 300km.  So, 
somewhere around 300 to 400km should be about the range of which you can 
depend on reliable communications on 75m.  At least, that's how it works down 
in Southern Central US.

He's a trip, but exTREMELY sharp as far as technical stuff goes!

6m will act closer to 10/11m as far as conditions are concerned, assuming the 
MUF gets that high.  But, it's been known to!
