[Lowfer] Re: Amplifiers for 136k

[BOB RIESE]

I suspect folks will do what they know best

but

should be aware the possibility of feed back
using the tank/antenna idea. The need to shield
the input could outway the matching problem
and SWR on feed lines at these wavelengths
should not be troublesome

the idea may work OK at a 1 watt level but at higher
power there could be instability problems
