Hi,

To reiterate what I posted a short time ago, I have a beautiful 
location for transmitting, salt water tributaries within 100' of my 
radials and a salt marsh for 40 of the 60 radials, the others are in 
the scrub beside the marsh & I'm using an Inv-L with the wire 50' 
high at best. I've been told I have a most powerful signal by enough 
DX stations, I believe them. I like turning the K3 down to 3W & see 
what I can catch. Being next door to the ocean is a transmitting 
bonanza.

My receiving antennas are the black hole though except the K9AY which 
does work as it should but isn't a gain antenna. It is the same salt 
water that gives me such a great signal that takes away from my 
receive. 

I have been offered some suggestions to what might likely be better 
for Rx which I'm reading on, I just wanted to put my positive 2 cents 
in in favor of saltwater & transmitting...
