You already have a TT4, why would you buy a TNCPi? No APRS client (APRX included) cares what type of TNC you use.? I have used APRX with a MTT4B on a Pi.? ?? My setup was the Pi Zero W and the MTT4b connected to the UART port (GPIO14 & GPIO15).? ?? The MTT4's Max232 chip was removed with resistors to drop the voltage (Pi Rx pin to ~3.3 V).?? ?? The MTT4B used 12V power because it has the built in radio.? If you used a straight TT4, it could be powered by the Pi.?? I believe the TT4 requires 5V for the procesor speed, and still require the resistors for the voltage translation. Option 2 would be to power the TT4 4 from the normal source (same as radio) and used Pin-4? power for the Pi. ? PLEASE CHECK POWER requirements first. If you had the Bluetooth Pi (Pi 3 or Zero W), and the Bluetooth attachment on the TT4 (or MTT4), you could have things running in no Time.? The BT would replaced the serial interface - no resistors required.? The 2 pieces wouldn't need to be connected, but it is ?? It really is configuration. Robert Giuliano

You might want to try one of the older I-gate softwares that will run on any of the 32 bit Windows like your WIN98. ? One is UI-View: ? ? ? ? Might be good practice to try it with your present laptop, especially if you're not concerned with a mapping display.? Just sending decoded APRS data obtained from RF to the internet servers is not a complex task and any PC and even microcontrollers can do that. ? Hank ____________________________________ ? ?

Already have several folks helping me out with that effort.? Now I just need to get a newer laptop to run the APRSISCE software.? The version from the Download requires something newer than WIN98. ?
