KX170B replacement options

I have an odd ball digital replacement 170B that is no longer
servicable. Since I already have the 155 and and moving map GPS, I need
a basic, inexpensive, nav/com hole filller for it as #3 radio. I really
like having it there. What type of used equipment is out there that is
a slide-in 170B replacement. Are there any of those digital MX170Bs
still around ? Anyone recommend a seller of inexpensive, used TSO
radios?

Check out the KX125. It has a built-in CDI and can be found both new
and reconditioned. I have one and like it a lot as #2, though there
are always cheaper options.

The problem for me is that if the radio is not a slide-in replacement
for the KX-170B it will cost be a minimum of $2000 to retray the stack
(because its a Mooney). In some cases its not even possible because
there are structure members behind the radios.

Someone pointed me to some KX-170B's and MAC1700's listed on eBay. My
existing MX-170B (TKM) also has a glideslope which I occasionally
remember to tune in as a backup to my real glideslope. If I buy a used
170B or MAC1700 how will that effect the backup GS? Is the GS
functionality built into the head, or the radio itself??

Thanks!

The MX170B will channel an external GS rcvr but there is no GS rcvr built
into the MX-170B. Same with the KX170B, MAC1700, etc...

So, if I'm currently working with an MX-170B and a working glideslope,
does that mean that when I put the MX-170B in the trash and put a
MAC1700 in (or KX-170B) the glideslope will still work??

Yup. You have an external GS rcvr, probably a King KN-73, somewhere in the
plane. Probably in the fuselage, aft of the baggage compartment. And don't
put the MX170B in the trash. Send it to me!

Do you think there is any value in the MX-170? The display seems very
effected by moisture. 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.

Why not just get a real KX-170B? They are plentiful, work great
and are cheap, relative to other options. It should just slide into your
existing tray.

The MX-170 is newer technology than the KX-170, flip flop memories,
etc... I have upgraded the existing radios on Fat Albert with the slide
in TKM series radios and been satisfied...
