KX170B replacement options

For the last couple of years it would be dark : during run up and would slowly come back after the moisture was driven : out of the cabin. Today, it went to 100.00 on all 4 freqs in : mid-flight. The company that makes it (TKM) refuses to fix it because : they want me to buy their new model and they don't offer the manuals so : no shop can legally work on it. Its too bad too. I had the exact same : problem with my KX-155, the shop simply replaced the display for a very : reasonable amount of money. In my opinion, TKM are just being butts : about this. I had a friend that got screwed out of his radio in the same way. Bought an ebay-special MX-170 that worked, but had a little display problem and the volume was a little low. Sent it to Michel since they would supposedly fix it for a flat rate (something like $200 or something IIRC). Well, they sat on the radio giving bullsh*t stories of how it was ready, no there was more broken, now it was in final adjustment stage, and finally he was told he had to buy a new one. Couldn't even get the old one back unless he paid about 1/2 the cost of a new one in labor for diagnostics. He also had a MX-12. After getting screwed on the MX-170, I volunteered to look inside a bit. They are built much cheaper than King units.... regular COTS ICs, sockets, ribbon cables, LEDs, etc. That's cheap and easily fixable: as long as you can get them to fix it or give you the info to do so yourself. Ribbon cables aren't chafe-protected, non-gold-plated connectors, cheesy DIP sockets for many ICs, etc. If you look inside a King unit, they're built to avionics standards... not cheapo consumer VCR standards. Hell., some of the king stuff I have seen don't even have solder mask on the PCB and they use old very cheap boards Not even fiberglass FR4 My recommendation: Don't by Michel anything. -Cory -- ************************************************** *********************** * Cory Papenfuss * * Electrical Engineering candidate Ph.D. graduate student * * Virginia Polytechnic Institute and State University * ************************************************** *********************** |
