Bill,
highly recommended. Never had any issue. Easy, cheap, reliable...

I'm looking for a device to protect my K3S front end when using a RX antenna.
As I key my rig I can hear the COR clicking and it's making me nervous.
I have seen the AS-RXFEP review by W1ZR in QST. I have also seen devices with
reed relays on the web. What are you using or am I just foolish

Back in the olden days, a small SERIES TUNED
circuit across the receiver input tuned to your
5, 12 and 13 MHz problem stations was quite
effective. It presents a low impedance path to
ground for the unwanted signal.

I''ve been somewhat frustrated with the same issue. I purchased the Array
Solutions (AS) Front End Protector, as you mention. When I first
connected it, I was treated with terrible noise and images all over the 20
meter and 40 meter bands. I returned the unit to AS, and they tested it
and
I couldn't agree more, Hank. That COR is a warning flag, and in my humble
opinion, not something I would consider for normal operation ;)
I'd also be interested in Elecraft's take on this. At what level does it
kick in? Also, what is the level of isolation between Aux RX In and the
main coax
Bill,
DX Engineering and Array Solutions both have protection devicees.

Bill,
I use that AS-RXFEP device and am 100% satisfied with it. I have run 550 watts
from my K-line system, through 110 feet of 600-ohm ladder line feeder to an 88
foot long doublet at 45 feet. My diversity receive antenna is a ground mounted
Hustler 5BTV (with radials) that is only 25 feet
The external reed relay /miniature relays are OK IF they are keyed by the
key line AND the RF is delayed a few ms from key line down.(K3 does this)
The diode limiter circuits like the AS and others like that don’t have this
limitation.
BUT I would be interested in the OFFICIAL Elecraft
