Re: Ooops, there goes my bargain DVM! It lives again... |
Nah, the Fluke will hang in there. They're great meters!
Yes, the AM rig is completely restored and up and running once again. I've had a lot of fun with it on 160/75/40 meters the past couple of weeks. Amazingly, the very first contact I made with it, an SWL made an mp3 of some of the audio and emailed it to me. Doesn't sound too bad considering its age and the fact that the audio had no compression or limiting!

|  Thordarson CHT-300 |
That rig is actually an "evolved" Viking One. When the internal modulation transformer shorted, I stripped it down to a simple RF deck and replaced the 4D32 with three 6146B final tubes running at up to 750 VDC. I use a separate modulator deck built up with a pair of 811a's running at up to 1500 VDC into a Thordarson CHT-300 watt multi-match transformer.
The Viking used to reside in a 6 foot rack next to the homebrew transmitter, but it was really under-utilized in the basement. So, over the past month I rebuilt it into a smaller rack and moved it upstairs to the more frequently used station. My wife's only comment was, "Is that going to be staying there?" 
Above is a picture of the modulation deck as it was being rebuilt. -- My Jeep is not an SUV. Your SUV is not a Jeep. |
