MMR-40 Front Panel
MMR-40 Front Panel
Here are just a couple more pictures I had in the camera of the MMR-40 Box Up…
The plan is to put a piece of red acetate over the display, then the front panel image over the whole thing. That should cover up any rough edges in the hole I cut out for the display. I replaced the incandescent light in the meter with a white LED that draws about 20 ma. It gives it a nice color, and should never need replacing.
I plan on putting both the digital display and the meter backlighting on an electronic switch that will light for about 1 minute when I momentarily press a button. That will save batteries when I don’t need to know what’s going on at all times.
Here is the back of the front panel. The KD1JV Digital Dial is on the left, and the S-meter/Power Meter is on the right. The Digital dial is held in place by two countersunk flathead screws through the front panel, but under the PC board faceplate.
I’ve gotten a little farther, but haven’t taken pictures yet, so stay tuned!
