I just have to ask, why would you set up a repeater if you have no idea how to program it or how it works? I highly recommend reading my post here. https://forums.mygmrs.com/topic/1402-you-just-got-your-gmrs-license-now-you-want-your-own-repeater/
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'm fairly new to GMRS and decided to buy a Motorola Radius GR300 UHF repeater off ebay. It is in working order with a duplexer and the Motorola RICK. I had some questions about the basics that I would appreciate some help on...
First off, I have successfully be able to program both the Tx and Rx for each unit (Motorola M10's). When programming I saw the original frequencies programmed were Rx 469.56250 and Tx 464.56250 on both M10's. I want to changes these to be Rx 462.57500 and Tx 467.57500.
Knowing this unit was in working order before, I assume the duplexer was tuned to the previously programmed frequencies. Being new to this, I am not sure if the the frequencies I want to change to will require re-tuning the duplexer.
Additionally, I am not sure I completely understand how having each M10 programmed to the same Rx and Tx between units works when it comes to repeating a signal... mentally it's not clicking for me.
Any information you can provide is greatly appreciated!

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

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.
I replied in the other thread. Thanks again!

I owned this radio for a few weeks. I believe yours is defective. You are doing everything correctly. Before you send it back for an exchange, have you tried programing the radio with the CHIRP software?
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...

I just received my BTECH GMRS-50X1 and I am having issues communicating with my local repeater. Hoping I could get some advice here from the folks that have this newly release radio. Here are the symptoms and configs...
My local repeater is on 550 @ xxx.0Mhz Tone in/out
Config: Channel 27 is set to 462.550 (offset is set by factory default to +5.000)
T-CTC is xxx.0
R-CTC is xxx.0
When I transmit to 462.550 I see the radio go from 462.550 to 467.550 when PTT is keyed. I see 'DeC:xxx.0' below the channel quadrants. My local repeater has a courtesy tone but I do not receive the courtesy tone when I Tx to it although I do hear traffic when people are active. My SWR with the 50X1 is 1.15 to 1.2. What's interesting is that I am able to hit this 550 repeater with my MXT400 using the same antenna and setup with no problems and a low SWR (1.15). I am also able to hit another repeater on 650 with the 50X1 successfully and hear the courtesy tone and was able to make contacts. This leaves me to believe the unit is programmed wrong or defective...
Additionally I am seeing that settings may not be storing correctly. See the videos below of me attempting to troubleshoot with BTECH support and the weird config storing issue. (I tried my truck antenna and home base antenna which both worth flawlessly with the MXT400)

Setting up a repeater

Thanks everyone! I will be diving into this project some more this weekend. I hope to have it up an running soon... One of the guys I spoke to on a local repeater has a guy who can help out with tuning the duplexer using a spectrum analyzer. Unless there is a way for me to do it without one, I'll be asking for some help. If all else fails maybe buy an analyzer... just to ensure my wallet knows who's boss.
