I have 2 of these radios and use one as my VHF Winlink gateway (KO4CTF-10) and the other as a cold spare. I am running mine via Signalink to a Windows machine currently, but bought the Pi TNC hat to use with one in the future. My only Winlink reservation with using it with the Pi is that VARA is not widely supported yet and that is the preferred Winlink protocol here locally versus 1200 packet. Once Linux and VARA gets sorted out, I will be looking to connect one up to my Pi and possibly use it as my gateway. There have been a few claiming ways to run it either through WINE or an ARM version of Windows on a Pi, but it hasn't been widely reported as stable and I need a guaranteed to run and stay up before I use it as my gateway.

PS: My FT-2600M is a workhorse, but if using it for digital, keep the power down to low or middle power. It is cooled by heat sink only and high on digital can be pretty hard on it. I have read they are known for shutting off on high power transmit and wiping out presets. Mine has cutoff on high power during initial testing, but I keep mine on 10w output since it is a gateway.
