Reflecting new addition to the project

A vintage ham radio station needs a matching vintage SWR-meter. That is exactly what I got today. It is beaten up and untested. Like its new housemates (DX-60 and HR-10) it could use new knobs. I plan to make new knobs for them all. White knobs may be the closest to the originals. Image shows prototype of black knob on the DX-60. I kind of like it. The orange one is half a joke. What do you think?

HM-11 SWR meter shown along DX-60.

The front is quite nice but the case is dented and and scratched. It would need a paint job to get up to the same standard as the DX-60 it will be connected to. One suggestion though is that I leave it as it is but clean and protect it with Turtle Wax.

You can see slight differences in the nuance of the colors of the paint. Heathkit used several shades of the green color. This has been a source of confusion and frustration for restorers.

Internal components may need replacement, but I hope the galvanometer works.

The meter comes from the estate of LA8KJ, kindly administered by LA3RK who I had the delightful experience of meeting for the first time.


It is a very conventional SWR meter with forward and reflected modes and a sensitivity adjustment so that the reflected mode can be calibrated in SWR. The intended frequency range is from 160 meter to 6 meter ham bands. Power levels up to 1 kW. As is common for such meters, don’t expect to use it for QRP levels.

The HM-11 is actually a new appearance of the AM-2. The circuitry is the same but the casing is styled to match the DX-60 and other equipment at the time. I think the technical term for this type of upgrade is SSNW (Same Shit – New Wrapping). Newer versions are HM-15 and HM-102 which are basically newer wrappings still.

The builder can select to build it for 50 ohms or 75 ohms by the choice of a couple of resistors.


The meter was owned by LA8KJ, Carl Daniel Haaøen who went silent key 2nd of November 2015 at the age of 86. He was licensed from 1965 but was an active participant in his local group long before that, including a period as QSL manager.

As a young boy he worked at two different radio manufacturers but later found a career outside radio. His sense of humor shines through in this piece he wrote for “Hallo Hallo” (search for LA8KJ).


Thanks to LA3RK, Olaf for excellent service and also some parts he gave me for another project coming up!
