  4. GMRS node audio setup

    Is there any adjustments for changing the courtesy tones and or the ID on it as I am using a controller with a link port on it.

    There's a file called rpt.conf under the directory /etc/asterisk which has lots of settings for tweaking the courtesy beeps, morse/voice ID, hang timer, and scheduling. It can act as a full-featured repeater controller if you wish. You just need to reload the configuration with "rpt reload" from the Asterisk CLI (by running "sudo asterisk -r") or just restarting the Asterisk service with "sudo service asterisk restart".

  5. GMRS node audio setup

    Assuming you're using the SimpleUSB audio interface, you can run "simpleusb-tune-menu" from the SSH command line. You'll get a menu where you can tune the RX and TX levels. The proper way to tune the RX audio is to have a service monitor inject a 1 kHz tone at 3 kHz deviation (for narrowband) or 5 kHz deviation (for wideband) and use the "rxdisplay" feature to get the audio level to be right around the 3 kHz or 5 kHz marks on the audio meter. With practice, you can tune by ear and get very, very close. A common thing to watch out for is the pre-emphasis setting. If you audio sounds too tinny or too bassy, the pre-emphasis settings on the node, repeater, or both are set wrong.

    If you're using the myGMRS image, don't run the "asl-menu" tool or you can mess up your node, since that is meant for hooking up to the Ham AllStarLink network.

  6. Best option(s) to link repeaters?

    in General Discussion

    For anyone who was interested in the new RT97 repeater that can work with the myGMRS Network, we have a limited number in stock right now (9 left as of my last count).

    The new model is the RT97S and it features a new metal case and a DB-9 port on the side for connecting an external repeater interface. These are FCC certified with the ID 2ASNSRT97.

    We're going to offer plug-and-play linking bundles with this repeater so the audio levels should be preset and ready to go very soon.

    Also, as of right now we're only stocking this new model instead of the original RT97. It doesn't make sense to stock both versions since they are so expensive, so we're just carrying the new one now.

  7. Nagoya NA-771G

    BuyTwoWayRadios is the exclusive dealer for the NA-771G model, so you would need to purchase from them. Anyone else selling them may be selling counterfeit products, so beware even on Amazon.

    However, the NA-701C model covers the GMRS band and also covers MURS, the 2m and 70cm Ham bands, so it is also compatible. We have these in stock and they are genuine Nagoya products.

  9. Registration Problems

    in Guest Forum

    There was indeed an issue with the data coming from the FCC (they changed how they share the data, and stopped updating the old method that was still working).

    As of this morning, it's been resolved and updates should be coming in as usual.

  13. Updated FCC Rules (2021) Pending - GMRS Location Data and FM on CB

    in FCC Rules Discussion

    Posted

    The only issue I had with this is that they declined to enforce a Busy Channel Lockout for automatic data/location bursts. You could set up your radio to transmit every 30 seconds, for example, and it'll beacon regardless of whether the channel is busy with voice traffic. Add in multiple radios in the same range, and I fear the GMRS channels will start to sound like APRS with data bursts all over the place.

    I had proposed the busy channel lockout feature but they specifically rejected it, claiming it was up to the licensee to ensure their radio is not causing interference. But once you enable an automatic location report, the licensee is relinquishing control to the radio for some period of time. It only seems like common sense for the radio to hold off the transmission until the channel is clear again. I'd also think the manufacturers would voluntarily add this feature as it would increase the reliability of their messages in the presence of co-channel interference.

    As far as FM on CB, I think it's great. It throws a lifeline to the CB radio manufacturers who can now introduce new FM-capable radios and revitalize the service a little bit. Seems GMRS has been taking over for quite a while, which is why some companies like Midland have all but given up on CB and moved onto making mobile GMRS products. For me, the interesting thing is that the reasons the FCC rejected digital voice on GMRS are the same reasons they initially denied Cobra's request to allow FM on CB. It fundamentally changes the nature of the service, it creates a compatibility issue between existing users and FM users, etc. They chose to mandate that AM is required on any FM-capable radios to ensure backwards compatibility. Using the same workaround, we could petition for digital voice on GMRS as long as digital radios are backwards compatible with analog on these channels so you can always talk to the analog people and hear the traffic on the channel. So for that, I'm very excited for the next round of interest in digital voice on GMRS. Seems a no-brainer now, we just need to file a well-organized petition for it with support from users and manufacturers.

    Recently bought one of the RT97's from you and the manual that came with it said output was 10W, however I have not measured that yet.  
    Will there be anyway to upgrade when aailable?

    Thanks,
    Tom

    Also very impressed with that 1st order from youre store!

    It's a 10W transmitter but by the time the signal is passed through the notch duplexer inside, the output is 5W. Because of this, we market these as 5W repeaters and that's the power the FCC has certified them at. 

    If the transmit and receive frequencies were further apart than 5 MHz, the duplexer would not have as much loss and you'd see something closer to 10W. 

  15. Chirp Integration Request

    If you're in support of the integration, we need your help to post on the bug linked above on the Chirp website. If there's not enough interest on that website, the author won't add the support.

    Posting here is nice but that won't bump up the priority at all.

    I have tried to log in ( WPTT519)  clicked on forgot password. put in my callsign not recognized.

    My e-mail is not recognized either. but if I click on register it says my callsign is registered already...

     

    any advise?

    The username associated with your callsign is daughertydev. Try entering that in the "Forgot Password" form. You probably had a different email address on file so it's not recognizing your new one.

  20. Repeater Database Hacked?

    in myGMRS.com

    Posted

    I just checked and I don't see any evidence of that happening. If you have more information to share I can look deeper into it, but the last update was today so I presume that was you correcting it. 

    It's possible the frequency defaulted to 550 or something if you made an edit for some other purpose and when the listing was updated it changed the frequency. Do you think that may be what happened?

    By Integration, do you mean having Chirp add the ability to download repeaters in my area from myGMRS in much the same way it can be done from the other site it supports?

    If so, yes that would be a nice feature. More importantly though is the need to support all the radios that are being used for GMRS.

    Exactly, myGMRS would be another option in Chirp for pulling in frequencies. You'd log in just like RadioReference and select the repeaters you want.
