Hey Doc,

Thanks for the input. I overslept for the 1300 UTC broadcast of VOK, but
did pick up the 1500 broadcast. Unfortunately the RF amp offers nothing
over the whip that comes with (and already attached to) my Sony 7600GR
portable. More work to be done. Need to tease out the secrets of
impedance matching, as well as add a boatload of additonal amplification.
Damn it's

No mater how much amplification you have, if the antenna is not big enough
or the proprgation is not good you will not pick up a station. There is a
limit as to how much you can amplify a signal before the noise floor takes
over. For signals below 15 to 30 mhz or so the noise floor is very high
so not too much amplification can be used to help with the reception.



Hey Ralph, thanks for coming in. I am wondering though if I can't tune out
some of the noise,and eliminate more with a directional antenna (which I
currently don't have.) Would an IF stage not help me here? Or a second
tuning function, on the output? Just wondering.

Do appreciate your comments. If I'm wrong I'm wrong, I was just thinking
these things might help. No? The signal I am trying to clean up is at 9335
kHz.
