TKM radios
A Cheetah I fly has a couple of these radios. The radios have been to the
factory and supposedly meet specs, and the installation has been checked out by two different avionics shops with no problems, yet these radios sound terrible. They garble, distort, flutter, sometimes one or the other can't be heard, etc. Yet at times they sound just fine. Is this par for the course with these radios? Or something to do with this particular installation? Next year they are getting replaced but until then is there anything I can do? |

Is this par for the course with these radios? Or something to do with
this particular installation? We had an MX 170B in our Warrior. It worked perfectly (still does, according to the current owner) 100% of the time, with wonderful clarity. My only gripe was the almost unusable memory feature, access to which required a motion that could only be duplicated while sitting on the ground with your arm on a rest. It sure beat the old mechanical King beast it replaced... -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

We just popped one into our Cardinal to replace one of the original Cessna
radios. It's working like a charm. Dave Reinhart Peter Gottlieb wrote: A Cheetah I fly has a couple of these radios.

No. Our experience: it has less power than the KX-170B but is otherwise fine. Or something to do with this particular installation? It's either the radios, or the installation, or something else in the plane. Gee, that's helpful. Do both radios sound the same? Do they have problems at the same time? Do they have the same problem with different brands of headsets? What about if you shut other avionics off when they're having problems -- intercom for example. Any change? We were having some radio problems a few months back. Tracked to 1) bad intercom ground 2) malfunctioning ANR headset. Still some occasional problems but it's not the MX radio, that's for sure. Cleaning the antenna grounds also seemed to improve reception Next year they are getting replaced but until then is there anything I can do? Can you borrow a KX-170B to replace one of the two and see if you have the same problems? It would help you isolate the problem. Another question: if you have a handheld, does it have problems at the same time the MX's have problems? RF interference from something on the ground is another possibility... It's probably worth some effort tracking it down since one would hate to spend thousands on a new set of radios only to have some of the problems follow along... Cheers, Sydney |

Hey,
Send me the paper weights and I will pay the postage. I bet you won't do it. I'll be glad to set up a Fed Ex or UPS. Make my day, John |

They will eventually end up on eBay. I suspect the problems are
installation related as the factory says both units are working perfectly. When the panel is redone all the antennas and wiring will also be replaced. "rkane33" wrote in message . ..
