Hello Terry
I would suspect the coax could be bad. Is it new or has it been laying
around awhile.? I have had water get into flooded RG-6 coax, and with
all the metals associated with the shielding, the corrosion has produced
a battery effect and there is DC voltage there as read on a high
impedance DVM. Of course the coax produced copious amounts of noise as
well. Critters had chewed on the new coax to allow water entry. You
can test the cable with an antenna analyzer or even a DVM. You should
see no leakage between conductors. If there is any resistance showing,
you have a problem. If you disconnect the beverage at the far end, the
noise should drop to zero with just the coax connected. If you hear
noise, it is coming in on the coax or is being generated within the
coax. Good luck and I hope you find the problem.

No matter where the beverage points to, terminated or not, hearing only
s5 static just seems not right to me.
Did you connect your antenna to RX IN (not OUT) ? What XFMR do you use?
Grounded the coax at the feedpoint by accident? What happens when you
leave the frontend protector out of the setup? Will your K3 pick up
signals when you connect your TX-antenna to RX IN?

Hi folks,
I put up my first beverage recently. It's about 550-600 feet of 17 gauge
electric fence wire running to the north about 6-7 feet high. Not terminated
right now but using a beverage transformer I purchased on qth.com and have not
put on the termination yet. Using a 5' galvanized ground rod at the transformer
and 75 ohm RG-6 surplus I got about 35 feet to my K-3 Elecraft thru an Array
Solutions frontend protector to the RX antenna connection.
All I get is S-5 static on the beverage. Even the strong stations barely make a
ripple of noise. Is this right?
I added some clamp on ferrites to see if the Common Mode Noise would be cut
down but after putting 5 on the RG-6 coax there is no difference. Just that S-5
static level on any band 80/40/20/etc. Right now I'm listening to P49MR on
14.250.0 Mhz and his 57 signal does not even come thru on the beverage when I
switch to RX antenna?
