I haven’t posted to this site in quite some time because I’ve been very busy with broadcast engineering projects. So I thought I’d take time out to do a few repairs on my Alinco DR-605 dual band mobile and share a few pics to show the improvements. I chose to start out by repairing the RJ45 plug end of the mic cable, which — as you can see — was looking pretty ragged and on the verge of totally letting me down.
After cutting back the bad end of the cable, I added some heat shrink tubing to the plug end for reinforcement and installed a new RJ45 connector. Much better.
Testing the radio after repairing the mic to make sure it’s keying and that there is audio from the microphone to modulate the radio
A successful start to getting this trusty old mobile (which I’ve been using almost exclusively as a base station rig here in the repair lab) back into better condition. The Alinco EMS-45 microphone checks out well, with all buttons functioning as expected.
With this sub-project completed, my next repair task on this DR-605 will be replacing the blown backlight lamps in the front panel display. I’ll actually be replacing the old, burned-out incandescent lamps with LED illumination, which will necessitate a little solder trace modification for the purpose of adding current limiting resistors. I haven’t yet decided whether or install “warm white” LED’s or blue.) I hope to have that done soon, but duty calls, so it’s time to pack up the tools and get back to doing what pays the mortgage, keeps food on the table, and keeps radio and television stations on the air and sounding good 😉
