APRS Packets transmit upon PTT release?

[Joe Shoemaker]

Hi Team, 

I'd like to open with how amazing this group is, and the information here has been outstanding!  I understand that if in dual mode, there is a chance that APRS packets could be sent on the wrong frequency.  When I select single channel (Not APRS) and release my PTT, a packet can be heard on the RX side. It doesn't matter how long the transmission is, a packet is sent. 

I have been doing some troubleshooting and the only way I can stop this annoying packet sound is to enter the settings and turn off Identification information and Location; Essentially turning off APRS all together.

I checked my firmware and I am running the most recent version.

Am I missing something?  I am new to APRS, and I know enough, to know I don't know enough...

Also, do we have any idea of a Apple CarPlay is on the horizon?  That would be super cool!

Cheers!

Joe

If you read the documents on the radio and settings you will find that you need to set APRS tx to the aprs memory channels.

If you don't it can and will tx on the other channel you have open.

Just set the tx for the APRS channel within settings... It's at the top of the page.

Hi Min,

Thanks for your reply! I have this set the APRS channel and even tried changing it from one saved channel to another to see if that would help with no avail. 

Any other suggestions? 

Kindly,

Joe

You have to have the radio connected and on General settings set the APRS channel to your APRS memory channel.. I use 16 as its out of the way....

Let me know if the iOS can do this as my old iPhone is not suitable now.

Hi Min,

I tried this, and even changed from stored channel 16 to channel 1, then back again. It's not like a full data packet, but some data transmits once I release the PTT.  I'll try to record a short video of what is going on and share it later.

Thanks again for all the support! 

Kindly, 

Joe

Hi Joe

If it's send data after a PPT release it's the location ID data that you need to turn off. It's a feature that tells other users their position and distance. Good features if you have HH and the radio. It's in the ID section and all 3 need to be off, a resent update turned them back on as default.

The documents I did detail this feature and to turn it off.

APRS is a timed feature and not PTT operated.

Beacon times are adjusted in the ID section and for testing you do it down to seconds.

The very early versions of firmware did mistakenly tx on the last band used... I know as I kept opening the local repeater 😕🤭.

It was resolved by the selection of the channel in the screen shot I sent. 

Please read the documents and testing I did on APRS..

Thanks for all the help, team!  

To make sure I understand, If I am going to beacon my location, and have set up my APRS configured correctly and specified a specific APRS channel (IE CH16), I will have a data packet sent every time I release my PTT, no matter what channel I am on? 

Is there a way that I can beacon my location without having that data packet sent every time I release my PTT on other frequencies? 

Thanks for all the guidance, I greatly appreciate it!

Kindly, 

Joe

Hi Joe

There are 2 things radio ID and APRS.

The ID is nothing to do with APRS and I suggest you turn it off. As it a data position only for Vero type radios.

You turn this off in the ID section of the app... Top 3 I'd buttons off.

APRS has its own page except for it's beacon times which is on the ID Page beacon for rf and Igate network. 

Hope this clears it up for you and it will stop the buzz sound at the end of a tx.

Hello Marnoch,

I have same problem as 'Joe Shoemaker'.  I've tried your recommended solutions and problem still persists ...on both of my N76 radios.

I cleared the APRS settings, turned OFF the 3 settings for ID signaling, and iGate  and location are turned OFF.

Then I used 146.520  Mhz as a quick test between N76 and a Kenwood TH-D75a.  The receiving Kenwood STILL screeches at end of transmission.

Firmware is 9.2 and HT application version is dated January 2026.

I'm out of ideas.

Hi Chuck

This is a feature in the Vero app .. 

At the end of each TX the sound is the position and location which other Vero radios can use to place the other on the map.

Most people turn this feature off.

It's the top 3 buttons/switches in the app ..All have to be off.

Do this in the app and send it to the radio to reset to the settings you want .

Hope this helps you.

Thank you for your quick reply.  I continued working on this problem and tested again to another handheld and noticed the noise may not be as bad as when I started this. 

 I've listened so many times now, I think maybe ... all I'm hearing now is s typical ... ending transmission.  My ears and mind are numb now ... from listening TOO much.  

My problem may be solved.  

As another test, I tuned in on a local Tuesday night net meeting and carefully listened to the end transmission of each member.  

Their end transmissions sound similar to the end noise that I now hear when transmitting to the Kenwood and a Tidradio H3.

Tomorrow, I'll test with some other operators to verify.

Thank you for helping.
