If I recall correct from flipping through the Radio Shack catalog at the
age of 8 or so, to look at all the stuff I *couldn't* have, cordless phones
used to be around 27 mhz, and also some were 49 mhz. Same went for Radio-
Shack RC cars. The "better" models ran at 49 mhz.

Follow-up, a little history he

It was probably an image of a 27 mhz phone.

There used to be a divorced woman who used to live next door to me
(there are six single sisters living in that house next door to me
now,their ages range from 24 to 31 and a couple of them sisters once
told me they would give me some Pussy any time I want it) and I used to
listen to her telephone conversations on one of my Radio Shack scanner
radios.A guy used to phone her and he would talk about picking up a
chick at the mall and all about his sexual fantasies with the chicks.

So, what did you end up with Coon: the pussy, or a sore elbow?

Maybe, but I've heard more than one which put spurious signals right in the
SW spectrum.

Even when your telephone is hung up,the phone operators can press some
switches and listen in to your phone.They can listen to sounds up to
about thirty feet away from your phone.Just as easily as listening to
music on the internet with computers and even webtv.

I haven't heard any telephone conversations with my two Radio Shack
scanners (Pro-91 and a Pro-33) in about seven or eight years.I guess
everybody in my neighborhood has spread spectum (or whatever it is
called) telephones now.I never have heard them on any of my other
radios before.Of course U.S.Mlitary and U.S.fed govt have some devices
that lets them listen to any telephone conversations and there are
U.S.Satellites wayyyyy up there that can do the same thing.

Back in the '70s and early '80s, cordless phones used, as I remember,
5 channels around 1600-1750 kHz for the base station, and 49 MHz for
the handset. Both FM, but you could receive them fairly well on an
AM receiver. Later they switched to 46 and 49 MHz.

I heard one neighbor, in the 3.5 MHz ham band, complaining that her
phone wasn't working well. It turned out to have a stronger
signal on the second harmonic than on the fundamental.

Some of them of them used frequency inversion scrambling which I found
out was completely useless as, even though it was an FM transmission,
it could be heard perfectly well on an SSB receiver. (Or at least on
my R-1000 which can run SSB with the 12 kHz wide filter).

Now they run on 915 MHz, 2.4 and 5.? GHz. Good riddance.

I also remember reading that some "smart" phones put out a spurious
AM signal on their microprocessor's crystal clock frequency. Pre-bugged
phones.
