I thought I’d share my setup. I have an HT radio, a Modem/MMDVM (my radio connects to the Modem), and a Rasberry PiZero (the Modem is wired to the Modem/MMDVM, which in turn connects vi wifi to my home wifi and the internet).
Radio, Anytone 878, I bought it from Bridgecom on Amazon.
AnyTone AT-D878UV Plus https://www.amazon.com/dp/B07RL8GYJ6/ref=cm_sw_r_cp_api_i_D9XgFbMKWVE40
Hotspot in two parts:
MMDVM, Duplex MMDVM from N5BOC of Lonestar electroincs.
PiStar. The above MMDVM modem sits on top of a PiZero, I needed to solder on a header to make this connection.
I needed a case to put both of these in to complete the hotspot.
I also needed a micro SD card for the RPi, I think I got this one.
Samsung (MB-ME32GA/AM) 32GB... https://www.amazon.com/dp/B06XWN9Q99?ref=ppx_pop_mob_ap_share
I used my Mac to download the Pistar software. I also downloaded some software to my MacBook to copy (burn) the PiStar software (image) to the SD card.
I do not need a PC for any of the above. Sadly though the Anytone 878 radio can only be programmed with a PC. But, I can program the radio from the keypad and not need a computer at all or a code plug. That is my understanding. I configure my hotspot via a webpage, mostly I use my iPhone to change the settings etc.
I hope this fills in another piece for someone.
I had a tremendous amount of help from Steve, K2GOG and Dave, K2JLV
