Hi…
On 30m using the 20m band-switch position, I’m able to get about 200w out into
a dummy load/wattmeter before the grid current rises faster than the plate
current. On 80/40 I can get over 400w out. Since I’m only interested in using
the amp on 80/40/30, I thought to improve the 30m situation a bit by adding a
few turns to the total pi-network inductance in the 20m position.
I’m willing to sacrifice a bit of efficiency on 80/40 to bring up 30 and
sacrifice 20/15/10 entirely. The goal here would be 300+ watts on 80/40/30 with
ease. I have already taken care of the input matching for 30 in the 20m
position.
I would appreciate any suggestions.
