[Elecraft] Trade off PR6 vs PR6-10 pre-amp

[John Buck]

Lou, I have received no other replies to my message.  Additional comments would be welcome.

In attempting to answer my own question, I suspect that the antenna bandwidth on 6M would limit out of band issues.  The slightly higher gain of the PR6-10 with the same noise figure then might be an advantage by helping overcome cable loss.  At least as long as strong signals are not overloading the front end.

I will probably not switch.  I presently have a good antenna on 24 and 28 MHz and do not really feel the need for more gain there.  Perhaps if I did not have the trusted PR6 I might purchase the PR6-10 instead.

John, did anyone reply to your questions? Have you made a decision? I am also wondering if making making the switch will compromise 6M performance.

I have the PR6 mounted on the K3.  Did successful JT65 6M moon bounce
with 11 element antenna,1000 watts, 110 foot BuryFlex coax, and
appropriate switching.  So this setup worked.

I note that the specification for the PR6-10 has about 2dB more gain
than the PR6.  The MDS and dynamic range specs are the same.

Would the 6 meter performance with the K3 using the PR6-10 be better or
worse than the PR6 because of:

1. Wider pass band?  More opportunity for out of band noise?

2. More gain?  Impact on overall dynamic range and noise figure?

My real question is should I sell my PR6 and get a PR6-10?  I do not
want to lose anything on 6 meters but perhaps could stand some
improvement on 10.
