More-or-less the same. I do recommend getting the SB-101 manual.

Yes - I ran the SB-101 and SB-102 on RTTY for years.

o Muffin fan over the final cage - pulling the air out.

o Muffin fan on top of the power supply.

o Run the transmit power around 50 watts.

o Now, this one I got from Irv Hoff himself - the problem is that, after
   45 years, I'm not quite sure which one went where - but if you look
   at the block diagram and do the calculations, you should be able to
   figure out which one to switch where. Here goes...

   If you put the LSB crystal in the USB crystal's position, it will
   adjust the passband PERFECTLY for the 2125 & 2295 tones - and that
   is in both directions - receive and transmit!

   As I recall, I bought a 2nd LSB crystal, unsoldered the USB crystal,
   drilled a hole close by for a sub-mini SPDT switch, installed the
   switch, soldered one side of both crystals together and to one side
   of the socket, and then soldered the other end of the crystals to
   the SPDT switch. Worked GREAT! I was able to still do SSB USB & LSB,
   and RTTY with the standard tones.

   Make you check payable to K2EAA...

I have yet to see any problem, however
complicated, which when looked at in the right
way, did not become still more complicated.
