I can't seem to get two radios to communicate over the same repeater

[WRQV660]

I have been trying to get two radios to use a specific repeater.  The repeater uses frequency 462.700000 and tone 141.3  The repeater info says that tone 141.3 is for both RX and TX. I configured two channels on each radio. One channel using "tone" and one channel using"tsql" to see if that particular setting made a difference.  I get the same result in both instances. Here is the process. I ask for a radio check on one radio. Nothing is heard on the other radio at this moment. Now, I release the PTT button and the radio I am speaking into gives me a kerchunk letting me know I hit the repeater. A second or so later, the radio I expected to receive the radio check message gives a kerchunk.  I get a kerchunk sound and light indicating I am communicating with the repeater on both radios. However, the verbal request for a radio check never comes across. Any ideas what I am doing wrong? Any input would be greatly appreciate. Than you.

Set one channel with both. Report back with your findings. Also, maybe no one is listening.

Talking on a repeater with nobody listening?

Try turning off the RX tone...make it no tone required. Then see if you hear the test. The repeater may not be passing the 141.3 tone. And the repeater may be malfunctioning.

It almost sounds like a Digipeater. Similar to a regular repeater, but it records your messages, then re-transmits it on the same frequency.

Just a guess.

Where is this repeater you're referencing?

[BoxCar]

What radio are you using, and do you have the repeater in a repeater memory slot? You transmit to the repeater on 467 and receive from the repeater on 462.

You can't have the radios right next to each other, desense from the transmitting radio overpowering the receiver. Try to get 10 yards or more between the radios.

Suggestion #1: Talking on a repeater with nobody listening?

Answer: In trying to explain the problem, I think I made my post more confusing than need be. The second radio I am using is the designated listening radio, to ensure there is a radio listening on that repeater that could pick up my radio check request.

Suggestion #2: Set one channel with both RX tone and TX tone to 141.3. Report back with your findings. Also, maybe no one is listening.

Answer: I setup a channel on both radios with frequency 462.70000 and a RX tone of 141.3 and a TX tone of 141.3 which gives me the kerchunk on the transmitting radio when I release the PTT button, and then a kerchunk is received on the designated receiving radio a second or two later without hearing my verbal communication. My request for a radio check is not heard on the second radio.

Suggettion #3: Try turning off the RX tone...make it no tone required. Then see if you hear the test. The repeater may not be passing the 141.3 tone. And the repeater may be malfunctioning.

Answer:  I turned off the RX tone and set it to no tone on both the transmitting and receiving radio. I still had the same outcome where you get the kerchunk with a static sound on both the transmitting radio and the receiving radio. The repeater is in Wooster, Ohio.  On MyGMRS.com it is identified as Wooster 700

 

Suggestion #4:  What radio are you using, and do you have the repeater in a repeater memory slot? You transmit to the repeater on 467 and receive from the repeater on 462.

Answer: I am using two Wouxun kg-935G radios.

If by memory slot, you mean programmed as a channel in the radio, then yes I do.

Correct. The transmit is 467 and receive is 462 (Offset of 5)

Suggestion #5: You can't have the radios right next to each other, distance from the transmitting radio overpowering the receiver. Try to get 10 yards or more between the radios.

Answer: I separated the radios by about a 1/10 mile and I still get the same scenario.

Are you on channel 29 (which is also referred to in the manual as RPT-22)?  That’s the quickest way to get everything setup.  Then as a bare minimum you just need to set the xmit tone.

Or, if you’re trying to program one of the user configurable 999 channels, have you seen this in the manual:

Accessing a Repeater in Frequency Mode
The REPEATER menu option (page 54) allows you to transmit to a repeater while
in Frequency Mode. If you are tuned to a GMRS receive frequency that is valid for repeater use and turn the REPEATER menu option ON, the KG-935G will transmit to the repeater input frequency when the PTT is pressed. The REPEATER menu option is ignored when the radio is not tuned to one of the 8 GMRS repeater transmit frequencies.”

It may be possible the reason why you don't hear yourself on the other radio and all you are getting is the kerchunk, may be that you are desensing the other radio with the radio you're keying up. 

One reason why you are not getting a response to your radio check may be that no one is listening and/or no one will make an effort to respond.

1/10 mile should be enough

[WRWE456]

I have not had the desensing issue with the 935Gplus. I don't place them right next to each other on a table but even just a few feet apart has not been an issue. They seem pretty immune to that.

Just getting back to basic's, have you heard any traffic on the repeater at all?

It may be a problem with the repeater. Is there another one near by that you could try?

The KG 935G is a great radio. I would be surprised if it is the radios causing the problem.

Maybe. That would depend on difference of the two signal levels being transmitted and being received by the receiving device, dB difference as measured in dBm. If my memory serves me right it only takes 4-6 dBs difference between the two signal levels to capture the other signal. If that is not the case, than nobody was either not hearing you for some reason or didn't feel like responding back.

I want to thank everyone for their help. Mystery solved. I do not understand the mechanics of the whole thing, but when I drove a half mile away from the other radio, instead of walking about 1/10 mile down the road, the radios worked on the repeater. It worked with both an RX of none, and an RX tone of 141.3. Evidentially a block down the road was not far enough. Thanks again!
