KC6VDX Band Plan
See you on the air!!

I built this radio from a kit in 1977. It served as my shortwave listening rig for 3 years, until I upgraded to a DX-100. Features continuous reception from 540 kHz to 30 mHz in 4 bands, regeneration control for increasing sensitivity, and tuning SSB and CW. |

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! |
