Gang,
I don't know how many were enjoying the debugging posts as much as I was.
But the two debuggers who killed all the bugs sure were good, didn't you
think?
The comment by Mike about the limit to max output being 3.5 watts (before
oscillation and spurious junk get wild) is correct. This is not a flaw in
Littlefield's original design so much as a consequence of squeezing it into
that tiny cabinet with that tiny circuit board. I think even my original
materials that came with my QRP30 mentioned that RF gets back into the '602
in the transmit chain when the drive goes past some point. There were
suggested cures, none of which were entirely effective. So, I respectfully
suggest that at 3.5 watts clean RF, the rig is "done."
I don't recall what the criteria for "fixed" were at this point. But I am
probably stating the obvious that when Mike used the QRP40 to work a fox, he
had definitively proved that rig is "fixed."
(Mike, don't miss your deadline fiddling with calibrating that dial!)
Wasn't this great?! Congratulations to both Debuggers.
72,
Preston WJ2V
PS Maybe I am so glad because I was # 4 on the Debuggers list and have been
relieved of the opportunity to embarrass myself!
