I was under the impression that aviation headset microphones were made to electrically look like a carbon mic, and that most ham communications gear used dynamic mics. Do you have information that refutes this notion? Nope, I know it works great with the LightSpeed and David Clark Mic. Set Mic Gain to 1 on the radio or will sound like crap. |

Portable Aircraft HF Radio Build (Going to Be Long) MultiplePosts....
OK, I am in the testing Faze!!!!
I will tell you I am really upset at Icom at this point!!! I Split the separation cable to find out that all the wires are coated with epoxy even under the shielding like stranded magnet wire.... Ok, 3 hours later i was able to solder an 8 pin connector to one side, About an hour later I gave it a go on the other side it took about 2 hours very very tinny wires. Icom just killed any repeat or future business I had with them. All and all it worked but took way longer then expected but all connection are mounted some finial routing of wires and she should be done. At nearly $50.00 a cable an average hobbyist would not be able to fix the cable if it got cut somehow. The bolts that will hold the aluminum chassis in to the case will also be rubber feet. Sorry no photos tonight.... Will Post when I can need some sleep eyes are not as good as they were few years ago and the tips of my fingers are no longer used to the hi-temps of the soldering iron. Icom BAAAAD BAAAD BAAAD!!! you deserve the Chinese or Koreans to make clones of your cables!!!! maybe now your radios!!! |

Its extension cables use standard, crimped-on modular connections, 4 pins for the control head and 8 for the mike. -- Jay Maynard, K5ZC http://www.conmicro.com http://jmaynard.livejournal.com http://www.tronguy.net http://www.hercules-390.org (Yes, that's me!)

Inside Wired With Pad. I Ended up drilling a number of holes under the side edge lip for Air and under the front I routed it out behind the name plate lots of air. Fan was Wired to Radio Out 12V so when radio is on fan is on fused with a ..5 amp fuse inline. Temperature while in Use is acceptable Levels High Volume Computer Fan http://www.internationalferryflights...T/S4010621.JPG Connector Side Of Unit, http://www.internationalferryflights...T/S4010622.JPG http://www.internationalferryflights...T/S4010623.JPG Left to Right, Ground. 2 Connector Left Of Fan Bottom is Power 3 Pin, 14V, 24V, & Ground (Eliminated Need For Switch And Slaved Ground to System Ground) Top Is Remote Head Mount 8 Pins, Fan Right Of Fan Top Is Antenna, Bottom Is Tuner Locked LED Inside, Antenna, Tools, Cables, And Connectors. (Pill Bottle is For Small Parts) http://www.internationalferryflights...T/S4010624.JPG http://www.internationalferryflights...T/S4010625.JPG Radio Control Head is Mounted In Foam, 1/2" Sides 1" Back 4" Front All items except tool kit are held in with 3M wire wrap like double sided Velcro hot and glued in place..
