[Elecraft] K2 IF amplifier output fault

[Brett gazdzinski]

It is a quiet receiver.
The only thing quieter I have run into, that still
hears weak signals, is my homebrew single conversion
receiver, and that is likely not as sensitive as the K2.

On both receivers, I have made the mistake in thinking
the antenna fell down, and gone outside to look.

Now I mostly hang out on 80 and 40 meters, and when its quiet,
it has fooled me more than once into checking the antenna.

Its sort of like the old days before all that noisy high gain IC chips
came out, when you had simple tube type receivers without preamps, when
it was quiet, it was quiet.

Nowadays, when its quiet, its not as noisy...
