Are you powering the ARR amp from the K3 or external PS?
My ARR pre-amp works fine - it is powered from external power, not from the
K3 accessory power.

Subject: [Elecraft] ARR P50VDG Problems
Hi Group,
Just recently hooked a Advanced Receiver Research P50VDG 6 meter preamp to
my primary K3/10. Right off the bat I heard a internal relay start
chattering with the preamp on and RX ANT setting engage (of course this is
all in receive mode). Turned everything off to re-evaluate connections and
setup correct. I then put the K3 into attenuation mode to eliminate some
of the gain, no luck.
Consulted with some fellow hams and Elecraft, Elecraft thought the 24 dB
of gain might be too much and causing an overload on the front end (and
the relay chatter). To make a long story short, I tried the suggestions
and still having the same issue. So I took the P50VDG to my secondary
K3/10, works like a champ and as I would expect. Now I’m wondering what is
different about my primary K3.
Short video of the noise which seems to be produced by the relay chatter:

Anyone experience this or have some suggestions? My primary K3/10 is at my
remote station using the K3/0, my secondary is at home and backup.
