Tri-Square is making interesting 900mhz frequency hopping, digital private channel HT’s with texting and weather radio. They have two different models and accessories. They are marketed as an alternative to the crowded FRS/GMRS bands. I believe these are part 15 devices.
My friend is using them for racing communications – they are pretty slick. I’ll try to borrow a pair for the July meeting.
