Update 12-31 2023 Rounding Out the Year
Update 12-31-2023. The last day of 2023. What better way to finish the year than to think about older boat anchors and how they can be rejuvenated to work on today's bands. Spending a better part of each day at the hospital where the only TV service is standard TV with the stupid quiz shows and of course HGTV, you basically go nuts. Quite often the OL is asleep and so not much to do but think about how to replace the drifting and non-linear Analog VFO's in boat anchor radios. No time to build stuff but lots of thinking time. One of my favorite radios is the Hallicrafters SR-160 (right along with the SR-150 which I don't have). But it suffers from a drifting and NON-Linear VFO. Based on my success with the Triton II, I asked why can't we do the same with the SR-160 (or National NCX-3 or even a SWAN 240). Well I think it can be done! The SR-160 used the old trick of a higher frequency VFO @ 9 MHz with a 5.2 MHz IF. Subtract the IF from the VFO and you get 75/80M LS
