True, the question is how much of the response I'll be able to copy! 
:-)  I have to keep CW slooooow.. :(

If the other end can copy, might be worth a shot, either slow CW or 
cross mode...  I will have to wire the key across the PTT though, the 
PTT is awful for CW - I'd barely manage QLF! :-D

I'm yet to be convinced, in the case of LEOs, because we NEED the 
popularity of FM to actually get a contact down here!  I used to try 
RS-12/13 when it was active, and the only QSOs (both SSB and CW) I 
ever had on it were pre-arranged with locals on FM before the 
pass.  I have even been known to have UO-14, SO-50 and AO-51 to 
myself for an entire pass!

Now when it comes to HEOs, that's a different ball game, because HEOs 
allow us to actually get outside our back yard.  And I plan on having 
at least V/U SSB ready for P3E and Eagle...  Should have put enough 
away for a decent station by then. :-)
