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!
