[1000mp] Apparent receiver overload on 80M

[Mike MacDonald]

Maybe it's just me but is there a need to have the preamp on using    40 or
80 meters? I find I rarely turn it on for any band.

Only on 80M, my S-meter runs S5-S7 all the time just on band noise. The
NB has no effect, and it doesn't sound like power line noise. If I press
the IPO switch, the S-meter goes to zero unless there is a signal
present. During the day, switching in 6dB of attenuation has the same
effect. At night, 6dB isn't always enough. These symptoms indicate to me
that something is overloading the receiver, but there is nothing obvious
to cause this. Any ideas as to what it could be, or is this normal for
the receiver on 80M with an inverted Vee?
