As another thought for linking a remote UI-View. How about putting your radio in the car on talkthrough. Have one channel on 144.800MHz (digipeater frequency) and the other on another frequency which can talk to a handheld (for example) in the building if necessary. This handheld is then linked to the computer.

Alas very unlikely to work, as the switching delay on the TT (however good) will be too long. Even if your packets do get through, the TX delay will be lost so the receiving station is likely not to decode. Same in reverse for incoming packets heard by your system.

Also some (many!) TT's mash around with the audio, so decoding will be a lottery.

It was just a thought. I'm still learning about the T/T's so thanks for the added info, and I forgot about the delays.

When running APRS on a network I use AGWPE for the data connection on a "server" machine, so you can then connect UI-View (or anything else, such as packet monitoring or beacon status add-ons) to the server over the LAN. Works stunningly well, most I've used is 7 clients but the capacity in this configuration is only limited by AGWPE's processing, into the 100's? 1000's?
 
I'm not familar with AGWPE other than I used it to decode APRS through the sound card before I had TT4's. Do you have a potted resume of what else it can do with regards possible RAYNET use and I shall go off and seek further info.

AGWPE does two different things.

The radio side allows use of either sound cards or external hardware devices for the TX/RX of the data. Although I've never used the sound card abilities, it seems to be very good at this, allowing packet operation from pretty much any PC without expensive TNC's.

The other side is to do with what then happens to the data.

Most people seem to run an application (e.g. UI-View) on the same PC that AGWPE is running, but you can also connect to it across a LAN (or the internet if you are brave enough to open your router!) as it acts as a server.

Consider a RAYNET control. The packet station (radio, TNC/sound card and laptop) is set up in a corner where it won't be disturbed / interfered with, each net operator can have a laptop running UI-View to view whatever section of the map they need, another can be used for a projector, the User Service can have their own, etc. etc. It's most likely that the machines would run receive-only (they don't need to TX), but any could do messaging etc. as needed.

Another useful way of working is the ability to have several applications running on the same PC (e.g. UI-View, messaging, terminal program, status monitoring), all using the AGWPE interface through a single radio. This is otherwise not possible as TNC serial ports cannot be shared, but AGWPE does this for you.

AGWPE sounds very usefull and something I need to learn more about.
