Hi:
can anyone give me any info on this rig? My student gave me two of them ,
his granma passed away and had them around the house.
Here are the specs. Anyone know about
1)Generally when they were built
2)Are they worth anything, other than a few bucks that a handheld CB radio
with one channel would be

7-Transistor Citizen Band Transceiver
(210-0102) Specifications Faxback Doc. # 45541

This is a Radio Shack part number.

Cheap walkie-talkies on the CB band were very popular until the late
eighties, I think, when the 49 MHz band opened up for this sort of
thing. Most of them are not very useful because they do not have a
squelch.

Circuit:
Receiver Section: .......................... Superhetrodyne with crystal
controlled local oscillator
Transmitting Section: .................... Crystal controlled oscillator
Semi-Conductors: ................................ 7-transistor and 1-diode
Frequency: ........................................ 27.085 MC (Channel 11)
Frequency Tolerance: ................................... plus/minus 0.005%
Transmitting Power Input: ............................... 100 mW (Maximum)
Audio Output Power: ..................................... 130 mW (Maximum)
I. F. Frequency: .................................................. 455 kC
Speaker: ..................................... 2 1/4" dia. PM Dynamic Type
Antenna: ...................................... Single Element Rod Antenna
Dimension: .......................................... 6" x 2 5/8" x 1 1/4"
Battery: ............................................. 9V standard battery

This appears to be better than most of them if only because it has
a superhet receive section. Where did you get these specs? Ask
Radio Shack for the schematics.

I doubt these are worth anything. When I was a kid people used to
move stuff like this to 10M AM, though. Invariably the modulation
levels were way low on the things.
