I came across a box of 10 of these RF modules made by Mitsumi Electric
Co. LTD.
the other day, and I need help identifying them, (schematic, purpose,
etc.) if anyone has a clue.

The box had a label with the following;
Messers. Lear Jet Corp.
Part No. 356-9802 Model No. FT-E3 Spec No. R-16-0053

On the front, you can see another number in the picture that reads,
"603.7.2" and all modules are identical it seems. On each side there are
5 solder connections labeled 1-5 on the left side and 6-10 on the right.
Number 9 is soldered to the front casing. The shaft seen in the front
view is part of a variable, (tuning) capacitor like you would find in a
portable radio. I don't have a ruler handy, but the module is roughly
2.75"X1.5" looking at the front. If anyone wants, I can post a picture
of it's interior.

These are old, but I have no idea how old. I don't hold much hope in
anyone identifying these, BUT stranger things have happened. If YOU know
what these are, I'd appreciate hearing what you know.

Thanks!
Bob

I probably don't know what you have, but I couldn't view your pictures.
How about posting them as a jpg or png and as a much smaller file.

Thanks,

Hi Jim. They are jpg files already, but I'll see what I can do about making them
smaller. They are as they came out of a Nikon Coolpix camera. Also, next time
I'll use a different posting program as I noticed the segments were not stitched
together when I retrieved the headers.
