Reviews
Having used coms with the frequency flip flop feature many times before I was a little disappointed with my new to me airplane having dinosaur KX 170s in both slots. After about a year living with them, and thinking I would have some panel upgrades done to several items at the same time, the Covid 19 thing has put dreams of a big upgrade on indefinite hold. I bit the MX 170 bullet and performed the install myself. It went surprisingly easy and took only about 10 minutes. The new MX 170 is performing great and I am so happy staging my next freq for when I need it with a push of the button! Little things like this spread out the workload and really help make flying more fun.
Radio arrived on time and in good condition, was exactly as advertised and works perfectly. Very easy install and no surprises. Very happy with purchase, product, and service.
Good replacement for a tired KX-175 in my Citabria. 5 minutes to remove the old NavCom and install the new one. Most of that time was spent removing the packaging. Good value. Like the Flip/Flop and memory functions.
Love it . Turn one screw , pull out old KX170B and slide in new MX170C and turn another screw . Like the advantage of having the flip flop channel selection .
Ive used these radios in several planes for 30 years. Slide them in and they work whether replacing King, Narco or Cessna radios. So far they have been trouble-free.
Slid right in and works perfect. Nice upgrade from the KX175 i was using.
Q&A
This is a replacement for the King KX 170 & 175 series Nav/Coms and the CDI you used with the King will work with the TKM 170C. Otherwise the TKM MC-60 is the only one TKM recommends.
No, the only version TKM makes is for the 14 volt replacement for the KX 170 & 175 series.
As this is a direct slide in replacement for King KX 170- and 175 series Nav/Coms, the Michel MX 170 would support the same glide slope indicators. This is a new unit.
The manufacturer’s warranty is 2 years for the MX170C Nav/Com radio.
Yes the MX170C is a direct slide-in replacement for the KX170-B. This will hook right up with the existing equipment in the aircraft that the KX170-B is hooked up to without any additional installation.
Per the manufacturer, the MX170C will automatically dim dependent upon ambient light conditions. The sensitivity can be adjusted using the trim pot located on the front panel.
This unit does not include a tray or connectors. These are sold as drop in, plug and play replacements. Trays and connectors are only available on the used market.
There was a transducer changed in the MX170B to meet new European standards, after changing the transducer TKM had to update the model number to MX170C to be in compliance with FAA standards.
Per the manufacturer a logbook entry can suffice but we recommend talking to your A&P to process any paperwork accordingly.
The display is digital.
