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.

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!

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

I replied in the other thread. Thanks again!

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) Factory Reset and reconfigure per instructions from support: https://youtu.be/E2uHXAyBnP4 Setting Storing Issue: https://youtu.be/ovlJnxGSQHg Any advice is appreciated!
