Title: heath HG-10 VFO Post by: W4RFM on June 08, 2011, 01:39:03 PM So I decided to make my VFO stand alone and not have to be plugged into a Heath product or other box for the 140vdc and filaments. I found a small enough transformer, that can be mounted on the rear of the chassis, and there is room for a half wave rectifier and filter cap on the inside. Has anyone done this with good or bad results? Thanks.

I know there are pros-cons and endless nay-sayers but I leave my self powered VFOs on 24-7 . So far the only side effect is good stability ;) Title: Re: heath HG-10 VFO Post by: W4RFM on June 09, 2011, 01:48:52 PM I found a mini Bud box after I posted, and thought the same thing, I will build it all in the box and put a 9 pin octal on it for the factory cable. Worst case, I add two/three screw holes to the Heath chassis!
Thanks Gary. Title: Re: heath HG-10 VFO Post by: W4AMV on June 09, 2011, 01:58:20 PM Gary, I have an HG10 which I received and it was modified to run on a supply other than the DX60. I re-wired it back since I had a DX60 to interface for its operation. In any case, the point, in the HG10 manual, they discuss this operation of a re-wire for other supplies. So you should look at the DX60 op manual if any questions come up in your mind. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
