[Elecraft] 6M Preamp

[Dave G4AON]

Julian, from my earlier measurements (from per my web site): "Adding an 
external pre-amplifier between the RF out and RF in of a KXV3 interface 
improves the sensitivity by 10 dBm giving 10 dB SINAD at -136 dBm in 400 
Hz bandwidth and a MDS of -146 dBm -which compares to an MDS of -136 dBm 
without the pre-amp. The pre-amp I am using is an Advanced Receiver 
Research Inc. model P50VDG with power derived from the +12 Volt output 
of the K3. There is no need to add a 10 dB attenuator after the pre-amp 
as the K3 attenuator works fine to reduce strong signals and in any 
event the pre-amp can be switched out by pressing the "RX ANT" switch on 
the K3."

The 0.5 dB NF Advanced Receiver Research 6m pre-amp is a similar package 
to the PR6, except it only has the IN/OUT sockets.

=================================

Well, given the current economic climate, at $250 (KXV3 + preamp) plus
shipping to get performance that the stock K3 ought to have been capable of
anyway, I think I'll pass on this.

I can always use the FT-817. Just how deaf is the K3 on 6m really, anyway?
