Greetings. You're not going to be happy with some of the things you're about to learn about APRS text messaging. For text messages relayed through APRS-IS, the sender doesn't know and can't specify

Looking to understand some obscure things about APRS messaging. In Understanding-APRS-Packets.pdf on John's aprsspec github site. (Tnx John!) RF to RF on same channel, well understood. Also

Hi Kevin -- haha that was a thread from more than a year ago! I kinda gave up on using a Raspi in the car, mainly because I couldn't get the RFI down to the level that my GPS and soundcard didn't

Hello Iain, In an APRS world, there are well known standards. A good page combining all this information can be found here: https://github.com/wb2osz/aprsspec In a classic packet setups, the

Hi Iain, This is outside of the SSID topic, but in my experience the most important part of a packet station is the antenna. All the other components of the station cannot make up for any

Thanks for the long and detailed reply. I own the WW2 bunker.? It is a commercial building.? BUT the radio is not used commercially.? The location of the bunker gives me a longer reach along the

Agreed, I am new to this technology and just import my TCP/IP names!? I will get there OK, I am still trying to understand NETROM.? I will keep away from the those SSIDs.

At the bunker I run a system with a BBS and chat and have links to the states over the internet to collect messages. So in total use 3 SSIDs.? Are there any particular allocation of SSIDs that are

Hi Iain, Based on your callsign you appear to be in the UK. I'm not sure why you emphasized that one of the two locations is a commercial building but in some (most?) countries it is not legal to use

Thank you David for your patience, problem solved. -- Regards, Phil

Hello Ian, It would be best to correct your terminology up front so we avoid misunderstandings. The "-1", "-2", etc items are called SSIDs and what you're calling "nodenames" is probably just your

Hello Josh, You haven't given much information here to help you. What operating system are you using this SDR on? What SDR application are you using with your Nooelec SDR (aka an RTL-based SDR

I just realized tha this will also disable packet acknowledgments and the connection will hang and tiime out. So: - make both stations the same SSID - make one purely receive only: it cant

As. you note, you must use different SSIDs for each site. And each site would then be accessed independently based on their SSID. You can then go between sites and compare behaviors. You can have a

Hello Phil, Nono.. you misunderstand. When I say "default" I literally mean it: ADEVICE default The word "default" is a PulseAudio/Pipewire special device that will send/receive audio to any

I have 2 sites - my home and my bunker.? I own both buildings and they are about 10 miles apart and in 2m contact.? The bunker is NOT residential it is commercial. I would like to run packet radio

Hi Josh, I'm surprised that you expect Direwolf to "see" any SDR. Direwolf looks for audio devices, not SDR receivers/transmitters. In order to use Direwolf to process the audio from a SDR receiver

I am at my witts end. I have been trying to use my Nooelec SDR with direwolf and direwolf does not "see" it and place it in the list. I have teied all releases from 1.5 to 1.7 to see if there is a

Ramon: Sorry, never got notified you had replied. I'm now digging into it on the Lenovo, prior to moving it into several other setups (Pi3B, VB VM docker host, XCP-NG VM Docker host. Got several
