Hello!
I bought a SW55 while studiing in Germany, and now that I have returned to Portugal, I have a problem.
In Germany, FM broadcast goes from 87.5 to 108 Mhz, but in Portugal it starts at 76Mhz. I would like to know if, by a combination of keys, or other means,
I saw a signal power booster for shortwave advertised at Radio Shack for $30. The ad says that it is good for apartments. I would like to know of anyone's

The amplifier is not the cleanest around, but it does add oomph to weak
signals. Problem in an apartment is that it amplifies electrical noise
just as much as the weak signals.
It works better on cheap portables (with antenna input jack) than more
expensive desktop sets.
Want mine? :-)

Speaking of which...
Does anyone have any advice on how to connect this beastie to a portable
which *doesn't* have an antenna jack? (Or how to add an antenna jack to a
portable? :-)
I have one of the active antennas which I used with another radio, but
would really like to take it to work to use with the $10 off-shore radio

Try making a lead that has a connector for the amplifier's output on one
end, and an allegator clip (Radio Shack has them) on the other end.
Connect the clip to your receiver's whip antenna.
Ideally, you should connect the ground terminal of the receiver's battery
to the ground terminal of the antenna's battery using a second lead with a
clip on each end. If you don't know which the ground terminals are, you
might want to *try* to establish a ground path by tapeing the receiver
and the amplifier to hold their cases back to back.
I am interested in obtaining several large posters (~3'x 3') of the
frequency spectrum assignments for as wide a range as possible. They will
be displayed in our Electronic Instructional Labs that pertain to analog
communications and microwave engineering.
