Very Reliable VHF Wattmeter			Time Owned: more than 12 months.
Given how long this wattmeter has been out there and how many thousands sold, I'm surprised there is no product review on it. I purchased mine years ago at a hamfest and it sat on the shelf. After I got my Kenwood TS-60S a couple years ago I wanted a full time 6 meter wattmeter attached to it. So I dug out my HM 2102 and proceeded to check it out. I performed the usual alignment against my Bird 43 and found that it tracked ok on the 25 watt scale but was off on the 250 watt scale. I looked into what mods were available and found 2. The first one was a capacitor change that was in the Heathkit Bulletin for Calibration Circuit Correction. Capacitor C2 was changed to a 17pf for 6 meters. So I swapped out the cap. The second mod was just what I needed, Separate High Power Calibration. What I did was take out R8, a 68K resistor and replace it with a 100K pot. So I adjusted R6, the low power pot for the proper reading and then the new R8 pot for the high power reading. Both scales track exactly as my Bird on all power levels to 100 watts, that's all the power I had to work with. There are a couple of other bulletins on Calibration and SWR null but I didn't need them. To be honest this wattmeter works way beyond my expectations for an inexpensive meter, it's extremely accurate, rugged and easy to repair. The pot I installed was a Radio Shack 100K 1/8 watt. That's what I had on hand. This mod will also work on the HF version, HM 102.
