Anyone ever see or hear of this antique?

[radcrow]

I have on my desk 2 Motorola Handie-Talkie FM Radiophone with cases and chargers.
Type CC1504
Serial E05957
Model H21DCN-3100 AW

Online I've found the manual for Motorola H21DCN-3114A Handie-Talkie and the Motorola model H21DCN-1100ASPO2. But none with this specific model #.
When I found this board I figured it was worth a try in asking.

Thanks

*I contacting Motorola and their Motorola Heritage Services & Archives said, "We have a manual for the H21DCN-3110A. Nothing with an AW though."

Low band HT200 with Private Line. I still have a carrier squelch model that works on 39.9 mHz.

Yep. 1w, low band, single channel, with PL which was a big deal in it's day. Worked on a few of them.

Low band HT-200 with PL is covered in one manual. There were not different manuals for every number in the suffix. The last digits of the model suffix are generally unimportant. They are not rare or unusual and date from 1963-70. Ones with PL are a bit harder to find than the carrier squelch style.

Anyone know if they are worth anything?

To a collector of older Motorola equipment it might have some value, but
probably not all that much, perhaps $25/$35. Unfortunately as a piece of
usable communications equipment in today's world it has none. The HT200
was Motorola's first portable of the handheld, not lunchbox, type.

Suggest you do a web/Google/Bing search for Motorola HT200 as that might
turn up a fair amount of information about the radios.

I still use one in my shop today........as a door stop

The neat thing about those radios was if you run your finger across your lips as you speak, you get encryption. You just have to run your finger across your ear at the same rate to get decode on the other end.

We used to divide into two talkgroups. One would use the radios normally, the other used the radios upside down.

Oh yeah - code inversion - that was all new technology back then.

I wonder if /\/\ will honor the warranty on the Permakay filter in that HT200?

I have a couple in my collection, one VHF and the other on 39.5 (with the "special" loaded antenna). I also have a Z13DLN, which was (I believe) the first intrinsically safe portable... built around the HT200 but the PTT is a large button mounted on the top of the unit, between the volume and squelch controls. It has a speaker/microphone that attaches to a hi-rose connector on the top also.

These radios were impossibly rugged, too. They had to survive a drop test from an ungodly height. We tried to break some at the ambulance company by throwing them down two flights of stairs so we could get MT500s. No luck. Damn things still worked after multiple attempts.

The PT200 was a conductor's pack set which used the same boards (separate T & R), with a 5 watt PA as an option. The battery pack was a collection of D-cells (11?) and would last for weeks which made them popular with railroads. I worked on many, including an HT200 that fell into a creek and was found 3 months later (Had squelch noise but that was all)
The radio was produced in low band and VHF, but I don't know about UHF. One feature of the circuitry which is never found now was that several transistors would be used in series with appropriate decoupling to perform different functions using the same electron flow.

I recall seeing at PT400 (P43DEN-1100AR) back in the early 70's. That model had a 10 watt PA,
telephone handset and used twenty-two "D" cells. With a weight of around 12 pounds, it was
necessary to use a sling to carry it over your shoulder like an M1 Garand.
