Data out question

[Broncus]

Greetings,

I am doing something which is probably not normal for most. I have a GPS connected to my U82 and the baud rate is set to 4800. Only the GPS-TX is connected to the U82-RX. This is simple, GPS data (NEMA) goes to the radio and I can see my position on APRS.FI. So far, so good!

Now for the "different", I have the U82-TX connected to PC-RX (laptop). The idea is to receive and display the digital data included in the transmission on the PC in some fashion. I would like to display the station eventually on a map. I am trying this mobile (no internet connection) so just looking it up on ARPS.FI or another similar tool is not an option.

Sometimes this works. I suspect that, at minimum, it is when a ID800H, V82 or a U82 is used on the other end with a 4800 baud GPS. Or at least the data port is set to 4800 baud.

Sometimes I get data that looks like it was sent with the wrong baud rate (or maybe it is because of R2D2). That is basically understandable, but I am not totally sure if that is the case.

So I have a question. If data is sent from a different radio through a data port at 9600 baud, should my U82 be able to receive it and send it out the data port? Typically the answer would be NO, not at all since it is a serial connection. However, this is not a true serial connection like a PC to a modem. Can the radio can receive the data regardless of the speed and then put it out the data port at the correct baud rate.

Has anyone tried monitoring the data in this fashion?

Thanks!
