Goofy Old Part 15 FM Transmitters

We are moving (how many times have I said

that before) and I am going through all sorts

of junk.

I found a "Mr. Microphone" type of FM transmitter-

actually - it's called a "Sing Along."  This is an extremely

low quality FM wireless mike for kids to scream into.  With

a little bit of luck, their screaming might come through a nearby FM

radio.  Maybe.  I have also (way in the past) taken old wireless mikes -

disconnected the mike element - and fed mono line audio into them

(somewhere in the circuit board) and have come up with very HIFI mono

short range FM transitters.  They didn't go far - but they sounded great.

I thought I could maybe do this with the "Sing Along."  with my budget -

any port in a storm.  Sometimes the "VFO" can be sort of stabilized - usually

after some drift.  Whatever.  

"Hey good lookin, we'll be back to pick you up later!"  Remeber that quote in

the old Mr. Microphone commercial?  You know.  Maybe like something "good"

was going to happen later?

Well, I started to test this thing - this toy "Sing Along" FM wireless mike.

Nothing good.  BLEHH!  What a piece of junk!  I didn't expect much, and I got even less!

A mixture of AM and FM, at very low deviation.  Maybe it's broken.  It's only

been sitting in the junk pile for 20 years!  More to follow - like - how far does

it go?  It is FCC certified, but the letters/numbers are too small for me to read.

To me, playing around with junk is fun.  

Speaking of fun, I found my old Ramsey FM-10.  I think I mentioned this transmitter

a few weeks ago.

A modulated free running oscillator, with a little RF "power" amplifier.  From

about 1992.  I put a fan on mine and a big bright red LED "power on" indicator.

(It's Cool!)

I don't know if it works, and I don't really care.  Either way, it's fun.  

I don't have the plastic "frequency adjust" (sp?)  tool. I had one a

couple of weeks ago and threw it away. (Man!)   It's also rigged for mono.  

I just turned off the 19 kHz pilot (crunch went my cutters) and there you

have it.   

More to follow, just for the silliness of it.

Brooce, WLP 1590 radio, relaying KDX at certain 

tmes of the day and night.

(Carl does all of the anouncements.  I just sit

there and eat popcorn and drink diet gingerale.  

The rest of the time I play my own weird music

that only I like. I have a toggle switch.  UP is

KDX.  DOWN is MY JUNK.  My junk.  Sounds like

Wally and Beaver Clever.  Here comes Eddie Haskell.

"Hi Mrs. Cleaver, what a nice hairdoo you have today.")
