Used DG-5s are expensive, I understand. However there are more "modern" equivalent counters that are way cheaper and still adjust the display to read the actual operating frequency...probably $49 or so. Might be worth it. The new ones won't match the "Kenwood" look but are very functional. It's difficult to make a capacitor-tuned VFO hold calibration across 500 kHz; so difficult that Collins (and Drake, and even Ten Tec) went to PTOs instead a long time ago. The Collins PTOs have a camshaft inside, with cams tweaked one-by-one to adjust tracking and keep the dial calibration accurate across the band...very complicated, but it worked.
