Thanks. I had checked with Ramsey and thought they were over priced, and

my
days of building kits have long passed. Gateway sells the kits or has some
other FM xmitter?

No others that I know of.. Radio Shack has one, but it's low powered, if I
remember it. The Ramsey went about 100 feet off a legal wire (30 inches, I
think) and the RS only about 25 feet. I am in a metropolitan area, which is
a disadvantage to these little units -- hard as heck to find a clear spot!
Then too, receiver AFC pulls off to something else if you suffer a fade.

Well, the unit arrived Saturday and I tried it out. This must be a city
version where people are crowded together. It's range is 30-75'. I need it
about 30' away from where I'll receive the final signal. Generally, I can
hear it, but have to do some fussing with the FM rcvr. Well, I'm not done
with the testing yet. They suggest putting it up high and/or putting a piece
of metal sheet under the xmitter. I had hoped for a xmission range of 100'
or more to get the signal to an out building. Maybe they have a 'country'
version. Yikes.

The CCrane version is a "full gallon" as far as the FCC is concerned.
I have one which covers my house, and 3 acre yard, with full quieting.
It is on the ground floor of a frame house, and sits on top of a metal
filing cabinet, and works equally well on top of the tuner/amp. I
have found that, as you would expect, the signal improves modestly as
you move to higher TX frequencies.

Is it illegal to put an unconnected piece of aluminum
tape on the wall behind one of those units?

Cecil,

Probably not, though it would require a careful reading to determine.
I doubt if a length of wire which just happened to be the right
length, and in the right place, would be an issue either.

Part of my problem is that the radio in the bedroom, where I do most of my
listening, is right near the noise source. I need the source on all night
(CPAP unit). The best reception of my favorite station is 30' away, across
the house, and I may not be able to find a better spot for the xmitter. Oh,
well, I'll keep playing with this. Higher tonight. (My rcvr is it a Crane's
getting repaired, and will be back this week I'm told. Until then I'm a bit
limited, since it gets the favorite station.)

Well, I did a fair amount of moving of receiver and xmitter around the
house, with modest success. My best spot is 35' away, and that's stretching
the limit of the xmitter. However, we now havd DSL after waiting 8 years.
Our den is much closer to the bedroom, and I can use RadioReplay to catch
the station. No interference at all, and I can sent it the short 20' to the
bedroom without much difficulty at all. I say much, because it seems like
the streaming audio runs amuck, and gets distorted somewhat like a too fast
or too slow conversation--alternating. However, most of the time all is
well. I can have the station going all day.
