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.

Recently I have been working the HELLSCHREIBER mode on 20m. visit the club site http://feldhellclub.org for more info. They have a monthly sprint and nets. but so far I have only operated during the last two sprints.
All you need is a sound card interface, pc, some free software and an hf rig.
I will update this post with links as soon as I get a few free minutes.
See my QSO from the April Held-Hell Sprint using using MultiPSK, SignaLink USB interface, IC7000 @30W, 66ft OCF up 35ft (4:1 current balun), and LDG Z11 Pro ATU. Also Ham Radio Deluxe(HRD) for rig control. HRD now supports Hell but I have verified its operation. It does work fine for PSK31 and other digital modes.
We're listed at the ARRL Field Day website - just click on the above link and type in K2QS, then click on the marker for more information!
