[Elecraft] RX Ant K3 Preamp vs External Preamp

[donovanf at starpower.net]

Hi Rich, 


There's a very broad variety of receive-only preamps on the market. 


I use the many Advanced Receiver Research P1-30/20VD preamps 
in my station and I've always been very pleased with their performance 
from 160 through 40 meters. Because they're broadband preamps, they 
should have a simple receiving bandpass filter ahead of the preamp.

If you're a technically inclined amateur there's an excellent overview here:

I was talking about RX antennas, like Beverages and such, so mainly 40m 
and 80m. I am happy with the K3 pre-amp I was just curious to what 
others use 

Thanks
