WILSON HH-464-D4 UHF
Mini-Com Handi-Talkie
W0UI

In the mid-1970s an American radio manufacturer, Wilson Electronics, 
came out with a line of (then) "miniature" VHF and UHF handi-talkies.
Since VHF (2-meters) was mostly the rage, there was not a big amateur demand for UHF.
Most UHF radios had found their way into the commercial markets.

Woody could not afford a new Wilson but watched them in the QST and other amateur magazines for years.
Eventually, when a used Wilson Mark II VHF 2-meter radio popped up 
in the Amateur Radio "Yellow Sheets" (pre-Internet, you know), he stretched to buy it. 
It was an amazing rig. 
Six crystal-controlled frequencies with 2-watts out !!
Later, when he could afford it, he upgraded to the Wilson Mark IV. 
These radios he still has today.

This Wilson HH-464-D4 is basically the UHF version of the famous 
Wilson Mark-IV amateur/ham handi-talkie radio

During 2013 Woody found this UHF hand-talkie on eBay.
Of course it had to come into the lineup here at w0ui.
Originally built for commercial UHF service, 
it is now in the early stages of conversion to amateur radio service.
Inside this rig is a Selectone ST-200A two-tone tone decoder.
When Woody bought this rig, 
it was crystaled for use in the RCC Mobile Telephone Service Channel 25 
(459.125 mHz).

Most hams today appreciate the versatility and compact sizes that synthesized rigs bring to the hobby.
Lost, however, is the thrill of having a "small and lightweight" HT 
where the battery itself is likely as big 
as most of the small handi's marketed now.



THIS IS A WORK IN PROGRESS and is not done yet.

I am currently shopping around to see if I can find 
amateur radio crystals that will work with this rig and 
will post the results here as things progress.

is located along the bottom the radio.
The decoder would trigger an alert tone to the person carrying the radio
indicating an incoming call or event.

Channel 25 (459.125 mHz).
