Hello Everyone:

Since posting the converter link, I have received many emails
from potential LOWfrers wanting to run the digital modes on 
1750 meters, and I am one of them too. According to what I 
read abt the LM318, it will provide a max. of 200 mW drive,
so a Linear PA will be necessary. And with the 1 watt limit
on 1750, a Class AB complimentary pair looks like what's
needed. 

For the benefit of Myself, and many others who will read the
replies, what are some suggestions for a Linear PA, with 
possible design / schematics, and parts list, to get a PA
that will run the Linear modes. I'm itching for something
along with the old faithful QRSS mode.

Thanks in advance to all who will share your knowledge, 73::
