[Elecraft] PR6-10

[Mike Reublin]

If you mean with the preamp on, yes the noise goes away. It sounds sort of like wadding up paper...not so much a whooooosh.

It's such a big jump on 10 & 12, not so much on 6. I haven't been aware of much noise since the last visit from the power company.

>> Question about the PR6-10. With no signal, and the preamp off, I get a gentle 'whoooooooosh' on 6, 10, & 12M, 1 bar on the S meter. 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.
