Flyingfisher Posted August 17, 2018 Report Share Posted August 17, 2018 Hi guys, I am in dire need of replacing at least one of my aging NAV/COM units... they are getting embarrassingly bad. I currently have two KX170b's in there and while the NAV portion of both works perfectly, pretty much everything else is a crapshoot. It's getting to the point where I don't even want to shoot IFR with them because it gets quiet and I have to wiggle the knobs and sure enough there's a controller repeatedly trying to get a hold of me. Anyway, sheesh... so the thing is... we just spent 3k on the engine. Just rewired the gear system, annual next month... we are bleeding money. I don't want to out more garbage in and need some ideas on what to do without breaking the bank. Please help. Quote Link to comment Share on other sites More sharing options...
carusoam Posted August 17, 2018 Report Share Posted August 17, 2018 Contact the guy with used radios... @Alan Fox to see what he has at what price... A garmin430W would be somewhat ideal... non-WAAS would be lower cost and put you in line with installing an Avidyne when funds become more available... There may be some slide in replacements or updates for the BKs called ... something like TKMs? That first year can be tough...

Just one thing after another. Having some intermittent charging issues now too. Smh... just.... grrrrr. Anyhow, I have a TKM in my trunk I got used super cheap but like... it doesn't broadcast basically at all and doesn't recieve barely at al, localizer has poor sensitivity as well. Avionics shop says it's fine but like... it doesn't work in the same damn slot as my good 170B so... yeah. I'll contact Alan thanks. Quote Link to comment Share on other sites More sharing options...
carusoam Posted August 17, 2018 Report Share Posted August 17, 2018 Contact cleaner and chasing all connectors all the way back to the antenna... PP thoughts only, no radio experience at all... Also Check the stuff for sale section to see if a KLN90B is for sale in there... great non-WAAS nav... Getting a Garmin com only radio is pretty low cost... All the install cost are the bummer... Key thing is a decent ILS receiver is important to you.. a non-WAAS gps won’t cut it... got a portable from Sporty’s for back-up? Nav/com/ILS... Or other...?

Andy95W Posted August 17, 2018 Report Share Posted August 17, 2018 There are shops that still work on the old KX-170s. Most of the guys who do really enjoy doing it. Your radios probably just need some tune up and basic maintenance work. Check out http://kx170b.com/ His site says he is closed after August 31, but he may be able to recommend someone else. 1 Quote Link to comment Share on other sites More sharing options...
Raptor05121 Posted August 17, 2018 Report Share Posted August 17, 2018 I have Narco Mk12D, working NAV/COM with GS, rack and connectors sitting in my garage. I'll let it go for $800. Quote Link to comment Share on other sites More sharing options...
Jerry 5TJ Posted August 17, 2018 Report Share Posted August 17, 2018 Icom A210 or A220 are available under 1 AMU, built in this century, a very solid comm radio. I put one in my C model at the same time I installed the GNS530W. The Icom was my primary comm because it was easier to use. 1 Quote Link to comment Share on other sites More sharing options...
1964-M20E Posted August 17, 2018 Report Share Posted August 17, 2018 Once you have verified all your connections to the antenna are good and secure, verify connectors on the tray are good and making good contact from the shell to the tray and all small wires to audio panels are good and secure You could always look at TKM they make a slide in replacement for your 170 yes it is 3AMUs but no installation. http://tkmavionics.com/our-products/mx170c-navcomm/ Quote Link to comment Share on other sites More sharing options...
EricJ Posted August 17, 2018 Report Share Posted August 17, 2018 Find a used KX170 that is servicable (they're not that expensive or hard to find), or a used TKM MX-170C. Both will be side-in replacements and owner servicable, i.e., ZERO installation cost. Slide the old one out, slide the new one in. Quote Link to comment Share on other sites More sharing options...
laytonl Posted August 19, 2018 Report Share Posted August 19, 2018 My son bought a used kx-170b last month from Texas Air Salvage for less than $500. It works fine. This is his #2 radio and #1 is a GNS430. Lee Quote Link to comment Share on other sites More sharing options...
Yetti Posted August 24, 2018 Report Share Posted August 24, 2018 STart with the simple things. Pull the radios and reseat them several times in the trays. Quote Link to comment Share on other sites More sharing options...
