MIDLAND'S WALKIE-TALKIE EMPIRE








"TOO MANY OPTIONS"











Welcome to September! Maybe it will cool down by December (😁). I'm sure all eyes and ears are watching the course of the Hurricane. Here's hoping it takes a sharp right turn and goes into the Altlantic where it belongs. And now, the Blog post -

Speaking of "right turns", and continuing on my loose thread on handheld CB's I wanted to take a look at Midland International and their "walkie-talkie Empire". While I've never heard anyone refer to Midland as having an Empire of anything, I think it fits in this situation.

Flipping through a 1967 Midland Dealer catalog I couldn't help but notice the quantity of walkie-talkies presented vs. their main competition (Radio Shack -  Lafayette). If you thumb through a Radio Shack or Lafayette catalog from the same time period you'd be hard pressed to find more than half a dozen handhelds in each one. Midland did not manufacture these in their own factories. Much like Radio Shack and Lafayette, transceivers were made overseas to their specifications. Also, like base and mobile radios, that were marketed under their own brand, exteriors would differentiate between models and other manufacturers - but inside, they were very much the same [I have another article comparing some older rigs "in the works"]

By comparison, Midland International's lineup was huge.

The pricing index guide which came with the catalog lists over 30 handheld models. From my experience I think that they could be lumped into a few catagories (100mw-1w-2w-5w), and within each category the circuitry would be the same, with the only changes being features and exterior cosmetics.

They were:

13-720  13-040  13-080    13-125   13-114    13-122    13-130   13-430  
13-732  13-050  13-104B  13-106   13-115    13-124    13-133C 13-040X
13-760  13-060  13-114    13-108   13-120    13-124B  13-410   13-050X
13-775  13-070  13-116    13-110J 13-120B   13-125    13-420 


MIDLAND 13-770
Headlining the catalog was the current flagship model 13-770

This was a 5 watt 6 channel behemoth that weighed in at 3.5lbs, and that was before you added the batteries! Much of the weight came from it's metal case. Your arm would certainly feel it after holding it up to transmit/receive for a length of time.

Because this was their flagship walkie-talkie I'm spending a bit more time on it that I would others.

The 13-770 specifications were:


  • 6 channels available with ch.7 pre-installed. (this was different than most other mfg. who shipped out with ch.11)
  • Superheterodyne w/ 4 IF stages and sensitivity better than 1.2uv (not the best)
  • RF amplifier
  • Call signal to alert a paired transceiver of a call
  • 90-100% modulation with 5 watt input
  • 60" telescoping antenna
  • 12 vdc via 8AA batteries or another 12v source
  • Battery charge switch for use of rechargeable ni-cad batteries
  • S-RF-Battery meter
  • Combination speaker/microphone (meh)
  • Squelch, volume, PA, call signal, hi-lo power switch
  • All metal cabinet with diecast chrome grill

OPTIONAL ACCESSORIES:


  • 18-137 Leather power pack to hold 8 "D" cell batteries
  • 18-138 External base station microphone
  • 18-143 External base power supply
  • 18-141 12v auto cable
  • 18-210 External base or mobile antenna
  • 21-420 Extension speaker
13-770 SIDE


The large channel selector knob had a strong "chunk" feel to it when selecting another position. Unlike other walkie-talkies it felt more substantive.

Like everyone else, Midland listed certain internal components for the transistor "counters" as if one less transistor meant an inferior product.

The 13-770 had 17 transistors, 3 diodes, 1 thermister, and 1 varister. You can find the 13-770 in CB28.

The 13-770 had a list price of $99.95



HENSHAWS 1972 CATALOG



Having spent a lot of space on one model, I'll condense some of the others worth noting -


  • 13-760    3-watt 6-channels. Squelch, call signal, combo meter
  • 13-133C  2-watt 2-channel.  Squelch, call signal,
  • 13-130    1-watt 3-channel.  Squelch
  • 13-122    100mw 3-channel. Squelch, call signal, battery meter
  • 13-110J   100mw 3-channel. Switchable noise limiter
  • 13-115    100mw 2-channel. Battery/S-meter. AM Broadcast band
  • 13-430    100mw 2-channel. Call signal
  • 13-104B  100mw 1-channel.


Of course, "list" price didn't mean you would pay that amount and Midland's were discounted most of the time, and usually the discounted price was the same across the board.

To sum it up, with 31 "flavors" of handhelds Midland truly had an "Empire" of walkie-talkies.
