I would like to see what mods are made to the 221 to do that and also what
kind of antenna system. I have a 221 I am using with a gasfet preamp in
the shack that should be less than 1 db of noise fugure and about 20 db
of gain. The antenna is a klm 22c and 75 feet of 9913 type of coax. I
can just see some sun noise with the antenna aimed at the sun. It sure
does not deflect the smeter several sunits. The antenna is on an azel
mount. I am sure the system is working as I compaired it to an Icom 706
and another antenna that is mounted on a tower and I am getting about the
differance in signal levels I would expect at the horizon.

The 75 feet of coax is your problem!!! What is the point of a 1dB NF preamp
with all that loss ahead of it? To see the benefit of the low noise figure
the amp must be before all that cable loss!!
