For those of you picking up legacy K3 rigs recently, you might want to
consider this option. The PR6 was designed to help boost 10M and 6M signals
as an add-on unit which plugs into the RX IN/OUT connections on the back of
the K3 with supplied BNC connectors.
A good preamp is VERY important if you live or operate with relatively
low RX noise on 12, 10, or 6M. For many of us, noise levels can vary a
lot from day to day, at different times of day, and even as neighbors
turn on/off their many noise sources. The PR6 preamp is a very good one.
I've not used it -- I already owned an ARR GasFET preamp for 6M, which
works well down to at least 12M, and used it at the RX Out/In patch
point. When the newer version of the transverter was introduced for the
K3S, I upgraded to it and loaned the ARR to a friend. The PR6 is a LOT
cheaper than replacing the transverter board. :) My guess based on a lot
of listening on 6M when my noise level is low is that the NF of the PR6
is within a fractional dB of the ARR GasFET -- in other words, quite good.
