Uniden Grant XL Repairs

 This is a Uniden Grant XL I updated for a ham friend. He wanted it updated, and brought back to factory specs, for his collection. 

I recapped a Turner +3 mic. I also installed a 3rd switch in the base to open the audio path on receive (to prevent feedback). I also drilled the rivets and installed new rubber feet, and wired it for the Grant. 

The radio got LED lighting, cap replacement of a few known failure items, additional reverse polarity protection, and a full alignment. This looks like NEW, but was actually made in 1993!

Heathkit VF-1 VFO

 This is a Heathkit VF-1 that I got from a friend. This was released around 1952 as a matching VFO for the Heathkit AT-1 transmitter. These have been found paired up with a multitude of transmitters. This unit was miswired internally, needed some TLC, and repair to the octal plug and power cord. I'm not sure it ever worked correctly, but it does now (with my DX-40).  I cleaned and repainted the cabinet, and compounded and waxed the faceplate. I can't believe the dark wear mark across the front actually came out!
















Swan 406 Remote VFO

 This is a Swan 406 remote VFO. It was pretty common for mobile operation in the 60's and 70's. This one wasn't in horrible condition, it just needed a little TLC. I cleaned it, serviced the rotary switches, repaired the broken remote cable and installed a strain relief on it, repainted the case, and she was ready to go. Since my Swan 400 didn't have a VFO (the 400 required an external vfo), it was the perfect lashup.











LED Workbench Lighting...

So, I'm cheap. Here's an example... I have a 4' light over my workbench, but wanted some additional lighting that was adjustable. I picked up 2 gooseneck desk lamps at Dollar Tree for a buck each (before they went to "everything's a $1.25"), reappropriated an outer cover from an old Motorola Micor, and had some old double-sided tape. I put that together, slipped it under my audio analyzer on the shelf, and this is the result :-)










President Washington Repair

 This is a President Washington SSB CB Base station I repaired for a friend. This radio was very clean! It had a transmit failure in the AM mode. I found the pass transistor in the AM power control circuit had failed. I replaced it with a device that was a bit more robust, and she was back up and running.
