[Elecraft] P3 and RF in the shack

[Alan Bloom]

All connectors (except the IF input of course) are bypassed to ground
right at the rear panel and have series inductors as well.  The shells
of the RS-232 and BNC connectors are directly grounded to the rear
panel.

I believe that's the plan.  However if the optional RS-232 connection to a PC is used, the customer is responsible for that cable.

It's hard to do a comprehensive job of testing for that since every
"hostile RF environment" is different.  Equipment that works in one
might not work in another.  But we definitely want the beta testers to
beat on the P3 as hard as they can.

There are many of us who have an intractable problem of RF in the shack due to space restraints that require the shack and the radiating part of the antenna to be too close.  (Loops in the attic, dipoles on the roof, rain-gutter antennas, etc.)
