PR6 6 Meter Preamp Installation

The photo of Ed's preamp on the back of his K3 looks like a very sturdy
mount.  But my K3/100 has fans and heat sinks on the rear, so solidly
attaching a 6M preamp via Ed's approach is not an easy undertaking.

Therefore, my PR6 Elecraft 6M preamp is attached with the recommended
back-to-back BNC connectors (no cables).  This installation results in the
amp sticking straight out the back of rig.  That concerns me because when I
need to shift my K3 or move items around it, I can tell that there is stress
on the preamp's BNC connectors and I can visualize them failing at some
point.

Which brings me (finally) to my question:  Since there is room inside the K3
for a second receiver and a 2M transverter, could there be a way to install
the PR6 (or similar 6M preamp circuit) *inside* the K3?  This would greatly
simplify packing for Field Day and other portable operations.  If this has
been addressed before I cannot find a reference to it.  Any ideas?

Hi Gary,

 

I certainly considered that, as that's the way I connected my first 6M RX
converter back in 1962.  Parks Electronics made my 6M outboard RX converter
back then, I believe.  My friend Bob Heil, K9EID, got me started on 6M then
and helped me get the Parks converter in line with my Knight Kit R100
receiver.

 

My most recent comment, while not expressed very clearly, was more in line
with making the K3 more compatible with travel, Field Day, DXpeditions, etc.
Whenever I can eliminate cables and outboarded accessories, I feel it to be
a plus.  I began to think about adding the Elecraft 6M preamp to the INSIDE
of the K3 cabinet, in lieu of another unwanted option or two and thus
eliminating extra cables and connectors, not to mention their associated
weak spots.

 

Just grab it and GO!  With all the advantages available for 6M operation
inside the K3 box.

 

Thanks for your reply.  Sorry I wasn't more clear in my post.

 

73,

Terry,

 

    If you are concerned about the possibility of the pre-amp acting as a
lever on the BNC connectors, then I suggest attaching it via a pair of short
coax cables (perhaps a foot long) instead of the back-to-back male couplers.
