Because I can't help myself... I like to learn new things and after using some local repeaters in my area I thought it would be fun to set one up. I also have access to a facility where a repeater being located there would be very useful for my friends and family.

I highly recommend you visit (and bookmark) http://www.repeater-builder.com/ They have the answers to all your questions, plus much, much more.

Since these are ending in .5625 rather than .565 or .560, there is a very good chance this is also programmed for narrow band operation.  You'll want to change it to wide-band for GMRS use.

You need to have the RX programmed to the HIGH SIDE on a repeater - 467.xxx. The transmitter will then repeat what it hears on the repeater's output frequency, which is the 462.xxx that your radio is listening to.
 
You WILL need to have the duplexer re-tuned regardless.
 
:...not sure I completely understand how having each M10 programmed to the same Rx and Tx between units works:
 
Both units are programmed to the same RX (high side) and TX (low side) so that the units can be swapped out if a final amp blows out or something.  One unit is always the receiver, and repeater controller.  It never transmits.  The other unit is the transmitter, and is NOT used for receiving or control of the repeater.  ...but the 2 units are swap-able for service purposes.

Thanks for the reply. I did use Chirp and still had the same issue. I will be returning for a replacement. If I get another bad unit I'll be looking for a different radio... 

Just tried what you suggested. The MXT400 did not open squelch. Hopefully the new unit works out when it arrives...

I noticed that in the first video, the DEC is not set.  DEC stand for Decode and ENC stands for Encode.  This describes that you are encoding a DPL code into the signal when you transmit, or you are asking that your squelch only opens when it detect an encoded signal, i.e. decoding the signal to open the squelch.
 
If you are not decoding, meaning DEC is blank and not set, that means you will hear all stations instead of selective stations.  If the repeater was tripped, you would have heard it no matter what.
 
Also, in the same video, when you transmit, the DEC changes to ENC and shows the proper code you programed.  This indicates that either the DPL encoder on the radio is broken or you possibly have the incorrect code.  The best way to test this is to get your MXT400, set it to receive on a channel with a DPL set.  Set both encode and decode on the BTech and key up the BTech.  Even without an antenna, the MXT400 just a few feet away, should hear the signal and open its squelch.  Don't try to transmit with no antenna connected to any radio.
 
Though, even if it works, there is something funky going on in the menu that has me concerned. 

I replied in the other thread. Thanks again!

I watched your videos after reading your post.  It looks like you are doing everything correctly.  I have good reason to believe your radio is defective.
 
I did comment on your thread, asking if you tried to program it via CHIRP of if you are only using the front panel programing options.  It's not likely that CHIRP will help, but it will all but guaranty its not something you are doing.
