I have an excel spread sheet that I just did to determine the approximate
tune and load settings for the pal 1k amp on each ham band.
I put a 1.8k resistor from plate to ground and hooked up the MFJ 259B to the
antenna output and found where the amp provides 50 ohm 1:1 match.
These settings will get you started with tune up if you don't already have
some settings. Some bands are kind of difficult to find without knowing
where to start.
On some bands I also used the adjacent band. Like 80 meters I used the 3-4
band and also the 4-6 band. Try each and see which works best.
On 160 meters I used 1.86 MHz as that is about all the plate tune cap will
do. It won't go much lower in frequency than that without adding a padder
cap or more tank coil.
If anyone would like a copy email me and I will send it along or if there is
a place to post it that is accessible that would be good.
