Globe Patrol shortwave radio

Inside view
|
This amazing radio could tune in stations from around the globe and deliver them at full speaker volume with only 3 transistors. It has a regenerative detector, a design that dates back to before the invention of the superheterodyne which is in common use today. It could be a bit fussy to tune, and would be more to the liking of the hobbyist than the casual listener. After upgrading to a DX-100 for shortwave listening, I sold my Globe Patrol. Then over 20 years later, I had a desire to experience tuning in signals with such a radio again. I found one on eBay and won the auction. However, it did not perform as I expected, would not go into regeneration and therefore would not pick up any shortwave signals. I was able to eventually get a copy of the manual. I traced the sequence of building, and location of parts. I found a transistor substitution in the regeneration stage. There was also a substitution in an audio stage, but it did not appear to harm the audio. After ordering an exact replacement for the original transistor, I pulled the substitute out, and put the new one in. What do you know, it worked perfectly! I got my regenerative squeal! With the supplied 10' antenna wire it received signals from Taiwan and WWV time signals. A 50' outdoor antenna pulls in all kinds of signals, from MW stations on up to 27 mHz CB and 10 meter ham. The Globe Patrol is back! |

Globe Patrol Manual
I have scanned
a copy of the manual. The scan is from a copy made at
300 dpi,
so I spent a lot of time retouching it and cleaning it up. Pages
are even, straight and clear of specks. They print decently. It is available
in a 4.5 meg ZIP file. I ask $2 for this, paid through PayPal. After I receive
a payment for the manual, I will email you the manual. Once
you download
it and
unzip the file there are no passwords or restrictions, print and copy
as many as you
like. Includes full schematic.
