[Elecraft] PR6-10

[iain macdonnell - N6ML]

Yeah, so I think that you might get some benefit from the preamp on 6m
(although if you have a S1 noise level without it, probably limited
benefit), but no benefit on 10m and below (unless your noise level
varies, and just happens to be bad today).

Turning on the PR, on 6M I get a slight increase in the 'whoooosh'. On 10M & 12M the S meter goes to S7 or so and the noise level goes WAY up, sounds like 160M in a summer thunderstorm.
