What's the difference between a tuner and a preslector?

What kind of radio and antenna are you using. Unless you are using
something really old I don't think a preselector or an antenna tuner
will do you much good at all. They will end up being another set of
knobs to twiddle and twist. You will find the tuner in particular will
raise the signal level, but it will raise everything and no new signals
will magically appear from the ether.

I've got two hi-fi tuners that overload on the outdoor long-wire (on
AM, of course). Is there a way to tune, preselect, detune, balun,
resist, or whatever the antenna so I can use it?

The simplest solution is to reduce the signal strength. cut back on
the gain control or switch in the attenuator if your radio has one.

This would be for general coverage and DXing.

Thanks.

(Not a tuner, but a preselector, which is much better.)

There's also the 1045C which is not designed as an active antenna.

http://www.mfjenterprises.com/produc...odid=MFJ-1045C

According to one of the techs I talked to at MFJ, this unit is to be
preferred over the 1020C, if your main concern is preselection. Of
course, it comes with no whip antenna. Runs off of a 9V battery as
well as from a wall wart (just like the 1020C). The description says
the 1045C accomodates 2 antennae and 2 receivers: not true; it's for
one antenna and one receiver, although it does have both a UHF and an
RCA connector for your antenna connection and the same for connection
to your receiver.

An R-1000 with an indoor random longwire. Eventually I'll set up an
outdoor dipole
or something similar.

Unless you are experiencing problems I would not look for a solution.
An R1000 will do just fine on a simple longwire. believe the radio
has an attenuator and an rf gain, and both can be used to minimize
strong signal effects.

Congrats on owning a classic.

It's a really nice radio. Got it off eBay a while ago. First
non-portable I've had in many many years. Should have done it long
ago. Blows the portables away.

If you're tuning an unbalanced, random-length wire, the MFJ 16010
L-circuit tuner is fine, and is only 49.95

For a balanced antenna, a dipole, say, the MFJ 901B Versa Tuner would
work -- it's 79.99

The MFJ 956 preselector/tuner is another possibility

Anybody can build an LC tuner for under $20 in about 15 minutes. You
need a tapped air core coil, a variable cap, a few clip leads and a
slab of peg-board. Excellent first project.

I have found the 956 to be useless on my DX394 w/Eavesdropper antenna, does
absolutely nothing for or against reception/signal.

HiFi AM tuners suck.

Compared to what?

Real radios.

They usually just throw in a single IC chip tuner that brick-walls the
high frequncies at around 4500 Hertz. If you try to use anything
other than the 6 feet of wire on a loop that comes with the receiver
the things will overload like crazy.

No gots. That's why the questions about add-ons.
Radio Shack sells Type F attenuators.
