Factory Reset on KG-935G

[DOODAH502]

I asked this earlier, but somehow my sign in info was corrupt.    I bought two KG-935G units roughly a year ago when they were first released.  Then bought another as a spare.  My wife's still works the same as it did initially, but she doesn't mess with hers which may be the reason mine has a problem now.

I, for some reason can no longer get my unit into the 462 frequencies.  I need to reach a couple of repeaters in my area that are in that frequency.  Every time I try and manually type the repeater frequency, it instantly goes to something like 463.02500, something similar.  I can't check right now because my radio is downstairs charging.

I tried looking at my wife's for a setting that's different than on my radio, but didn't notice anything.  I'd like to try a full reset to see if that brings all the original bandwidth back.  I use Chirp, but can't find anything on there that will make a restore, even though I've found similar wording.

Anyone have any ideas or a known fix?

I can't figure out how to reply on here, so I'll try this in a while to see if that resolves it.  I hadn't looked.  I don't recall changing any setting in that category, but who knows.

I think @back4more70 may be right on this. If not try downloading your wife’s settings in Chirp and then upload those to your radio. You can compare the two for every setting too.

I’m not clear on your question about replying so here’s the pedantic version:

To reply while quoting the post you’re replying to, simply click on the word “quote”.

To reply without quoting, just go to the bottom of the screen and type in your reply.

In either case you then click “Submit Reply”

@back4more70  That seems to have been the solution.  Thanks to all who answered.  Now I have new questions.  Is there a more or less default offset for repeaters?  And using the aforementioned device, how do you search for tones using this thing?  If you know.

The default offset is +5 MHz for GMRS.  So, if your repeater is transmitting on 462.550 MHz you will transmit to the repeater at 467.550 MHz.

As far as searching for tones, the feature is probably covered in your instructions.  It will be called “scan for tones” if it is.  But you must be scanning the transmit frequencies to be certain because the transmit tone is not always the same as the receive tone. It’s usually better to just ask for access and be given the tones.

I would add to @Sshannon’s info that most GMRS radio (if not all) will have this +5 offset already added in the preprogrammed channels for repeaters.

21: TONE-SCAN] CTCSS/DCS Scanning
Function: Scans the incoming signal for CTCSS or DCS tones to identify or confirm the correct tone. This function must be activated while receiving a signal.
Options: 1. CTCSS/2. DCS
Default: None. Choose the function and press [MENU] to activate the scan.
Note: The scan will stop when the signal ends and resume from where it left off the
next time the signal is received, until it identifies the correct tone. Use the [UP]/[DOWN] arrow keys to scan in a different direction

On your "Tone Scan" question.  Buy Two Way Radios has a write-up on doing just that:  How to use Tone Scan on Wouxun two way radios (buytwowayradios.com)

Hope this helps.

I have had the exact same problem - a local repeater is working on all my other GMRS radios except the 935G [this problem has been going on for two years]. Are those the settings I need to have to fix the problem. I just did a test and the repeater with 462 worked great on my other radios except the 935G. I was actually considering a factory reset and that is how I found this thread.

The frequency limits in his picture were obviously not the problem. People here would need a lot more information to understand what your problem might be.  Something showing how you have it programmed in the 935G would help.

I hope some can help me. Below are Chirp files below.

They look the same so a couple thoughts on what to check for…

What location (channel number) are you programmed into?

What’s your squelch setting? Could it be preventing the radio to open on receive?

Are you using the factory GMRS tuned antenna? Any change if you swap antennas?

If you transmit on simplex (channel 17) can you hear and be heard on another radio? Make sure they have some space (50’) between so they don’t desense each other. 
I’m not sure what’s happening but there’s some ideas of what to check. 
 

edit: one other thought, do you accidentally have talk around engaged? This would cause you to transmit on the receiving frequency and would prevent opening the repeater.

Another thought…

[WRUU653]

More on talk around.

If ‘talk around’ is engaged you will see an ‘R’ on your screen to the right of the W+. This can be engaged or disabled by one of the side buttons or a quick tap of the scan button. When you press the PTT it should show you on the screen what frequency you are transmitting on if you select frequency mode for that channel. Press mode three times to get there from channel name. 
I hope some of this info helps you out.

They are both the same channel number - I try to keep all my radios - GMRS or UHF/VHF the same cloned - for consistency

I'll see about the squelch setting

Are you using the factory GMRS tuned antenna? Any change if you swap antennas?

I'm using a variety of nice antennas - and the same result regardless of antenna - works on my other radios and not the 935G =( [Nagoya NA-771G / Smiley  / Comet CA-2x4sr ] so when I test it - I test both under same conditions  - standing in the same spot, same antenna, etc.

If you transmit on simplex (channel 17) can you hear and be heard on another radio? Make sure they have some space (50’) between so they don’t desense each other. 
I’m not sure what’s happening but there’s some ideas of what to check.

I'll have to try that - I don't have the radios with the stock order - I do have the traditional GMRS channels - they are just not in that same spot as factory programmed- so Channel 17 may be somewhere else - not the Channel 17 proper

edit: one other thought, do you accidentally have talk around engaged? This would cause you to transmit on the receiving frequency and would prevent opening the repeater. 

Ill check for this as well ^^

Wow, this is also very helpful, Ill try all these suggestions, thank you for helping me

Ok, I just did all these things - here is the report

• No R is appearing next to W+. 
• When press PTT [after pressing mode three times I see 462.7000]

Sounds like we’re getting somewhere. Double check that but if you are seeing 462.700 and not 467.700 when pressing the PTT then you are transmitting on simplex, not the repeater input.

The repeater channels are 23-30, 30-38 and so on. If you have changed their locations on a GMRS radio like the 935 it’s possible that it might not transmit on the correct frequency but rather the simplex frequency. I haven’t tried moving them from their natural order. If what you are saying is correct and you are seeing 462.700, that’s what’s happening and is the problem.  You will likely have to put things back in order. 
 

edit: 

A factory reset would certainly put things back with the repeater frequencies back where they were intended. I guess it all depends on how much you have programmed in the radio and what’s the most straightforward approach to putting things back in. I use Chirp and it allows the ability of cut and pasting which is great because like you I keep my radios mostly programmed the same so the same stuff is in the same locations and I can transfer from one radio to the next. Good luck I hope this is the fix you need.

I really appreciate you helping me. It will be no problem if I have to do a reset - I just love Chirp and have everything backed up. =)

I usually am in the mode where can see the name of the channel. 

So, at your advice I double checked - So, when I look at the frequency before PTT it is 462.55000 when I push the PTT it is 467.55000. 

So, I'll give it one more go for your advice and then do the factory reset. It's just so strange I just copied and pasted the files in chirp in the the Radioditty UV-5G Plus and it works like a charm. Hmmmm - 

Thank you again for your patience. I really appreciate you helping me. I miss that repeater

If it goes to 467.xxx on PTT then it’s doing the offset correct. However before you said the channel was 462.700 not 462.550 so if it’s supposed to be 700 and not 550 it may well be in the wrong channel location or something didn’t get set right. 700 should be at channel 29 or 37. 
One thing I can say is I have made mistakes in a cut and paste before. Where when I went back for some reason or another some of my corresponding frequencies weren’t copied correctly. I never knew why but I was looking things over and found a couple that weren’t what they were supposed to be and I just had to change it back. 
I’m happy to help if I can and hope that in the end everything works for you.
