[Elecraft] Loud relay click on CW using RX ant only on some bands

[Dick Dievendorff]

Sounds like the carrier operated relay trying to protect your radio's front
end.  Perhaps a bit too much signal is reaching your receive antenna from
your transmit antenna.

You might want to consider a "front end protector" that limits the received
signal on your Rx antenna.  

Several have reported success with

KD9SV developed a "front end saver" that is sold by DX Engineering, see
http://www.dxengineering.com/search/brand/kd9sv-products  I have one of
these, incorporated into a receive antenna switch with preamps.

There are other solutions. In the old days we'd put a pair of diodes back to
back, but that's a particularly noisy solution...

Hi folks

I've been enjoying a new RX Loop antenna with my K3.  All of a sudden, every
dit and dah (every key press) produces a relay click whenever the RX ANT is
active.  I swear that wasn't happening before.  With very similar settings,
(VOX, QSK, ANT1 RX, AGC-F) I hear the relay on 40 meters but not on 20.  SWR
is normal, using VFO-A, nothing unusual.  When I back the power down to 5W
or less, it stops clicking.

Anyone know what I'm doing wrong and how to fix it?  Probably got it into
some strange mode again!  Although I'm fairly technically savvy, I am still
getting to know my K3.

Thanks,

Chris
