"Certified Used" 6400M delivered today - ATU doesn't appear to be working

N7CXI

Received the 6400M today, unboxed and hooked up this evening.
Everything seems to be fine so far except the ATU.

Pressing the ATU (quickly) pops up a gray "TUNE" balloon in the display, but no flashes or relays. The "ATU Mem" button in the TX menu appears to be disabled. ("grayed out") I did, in fact read the ATU section in the manual several times.  I also did a full reset, (white button) but that had no effect.

Pure speculation on my part, but it's almost like the radio doesn't know it's supposed to have an ATU installed.  

Any ideas?

- other than that, simply brilliant so far. Beautiful display, excellent GUI design. TX audio is red hot, at least with my drill-sergeant voice. :-)

Thanks,

I have a 6400 thats waiting for its ATU to be delivered. That’s exactly what mine looks like when no ATU is detected

Thanks, Tim.
I suspect the ATU is either missing or something shook loose in shipping?  Hard to say. I'm tempted to pull the cover and peek in there to see, but I'll wait until I hear from Flex. I have a PalStar AT5K-HP I use with the amp anyway - no crisis.

Jim - My suspicion is that if you are not getting a state indication (above the ATU button in green) - then an ATU is not being sensed. Good luck!

Jim, Looks like the radio is not seeing the ATU. I suggest you enter a help desk ticket. Flex will then contact you to troubleshoot. Eduardo, KC8R

Was going to post  as well, I would check and see if the ATU is even installed, I have a 6400 NON ATU rig and it looks just like you posted above. Check the specs and check what you ordered as the 6400 s available With and Without the ATU as its an option on this model.

Jim if it was listed that way on invoice and description , I'm sure they will work to make it right, BTW the ATU is a field install-able unit.  Which is why when I ordered my 6400 I opted to not get it right away and use my dedicated tuner instead, knowing I could if wanted or needed some point order the ATU and install it myself.

Well.....I think that doesn't always work. This ATU works great but has never shown up as an option. Go figure.

Jim, it looks like you have 6600 according to your Radio Identification. I think the Tuner comes standard equipment with a 6600 and therefore that might explain why it it doesn’t show. I have a 6700 so I may be wrong 73 de Winston

Let the antenna do the work.
