Hello, I rescently baught a 7600GR. I'm planning on putting up 80 to

foot longwire/random wire between my house and a large tree.
Any input on the following tuners? I'm a newbie with this kinda stuff.

Several have suggested a passive one. The list cost on these seems
rather high, are there cheaper tuner/preselector options without
giving
up quality/usefullness?
Secondly, would a low pass filter still be useful with a tuner?
Thanks,
Bob
Of the two, I'd go for the passive one. You certainly won't need gain
with that setup.
If the preselector alone isn't enough, you might look to add a variable
attenuator to prevent overloading. You can make one of these dirt
cheap.
But actually, I'd consider going with a much smaller antenna, away from
the house with an impedance matching transformer, and use the savings to
start a table top radio fund.
Excellent advice Mark,
Far more advantage can be gained by using a matching UNUN and proper
shield
grounding- otherwise noise from the house is conducted right out to the
antenna. A lot cheaper and less knobs to fool with too.

I have been lurking for a while but I need to ask a question he
I am new SW listening (actually, I am recently returned to the hobby). I am
not an expert. I see this thread talking about how to build (various styles)
of antenna, but no schematics. I think that I understand the concepts but an
actual drawing would be helpful. A generic parts list would be even better.
I do tend to overload my little portable with a 20 foot longwire so anything
to improve/refine the reception would be a huge help.
Thanks
Eric
