David oh for the old days. If I put my ear to the ground I could hear it
down in Franklin Ma. :-)
But its been a pretty steady -50 db here on the whip and preamp.

lot of noise and spherics in NH such that an Austron 2100F is locking.
There is a big difference between 1MW from Nantucket and 75kW from New

Its on the air now.
Its a 4-8 foot whip that screws into the top of the preamp. Its just a

What time of day did you measure that signal strength?
And what are the characteristics of the "standard marine preamp"?
Most importantly, what field strength corresponds to 1000 uV output from it?
Thanks,

Hello to the group.

I have just discovered one of my favorite HP 3586 SLVM has an issue with
sensitivity.
For reference in Boston on a second 3586 the level is -51db avg. or 1000 uv
using a standard marine preamp 6' off the ground. The signal should remain
on until the
