I have published two articles on QRP-Plus modifications and enhancements --
the first appeared in the January 1997 ARCI QRP Quarterly and the second in
the April '97 QRP Quarterly. If you are not an ARCI member (shame on you!)
and would like a copy of the articles, send an SASE to me at the address
shown below (be sure to tell me what it is for!) If you would also like a
sample QRP Quarterly (not necessarily a recent issue) and a member
application form, enclose $2 (to cover mailing of the Quarterly).
There is one minor correction to the April article in the section "An
improved Final MOSFET". The 33 Ohm resistor in the feedback network should
be 1/2 W; I originally used a 1/4 resistor and it showed signs of "heat
stress" after awhile. I am now using two 68 Ohm 1/4W resistors in parallel
as this required less mounting space than a 33 Ohm 1/2W unit. By the way --
I have now performed this mod on a "new improved" model (commonly referred
to as a "QRP++") and it works great!
