I have two radios in Old Blue. A GMRS radio within my Rino and a CB Radio. Gonna switch to HAM when I get the time to get my license. I downloaded Zello since everyone I know has cell phones. The only problem I have is that where I like to wheel, there isn't any cell signal. I will give it a try though. I will have to con someone else into downloading it so we can give it a try.
My specific use-case would be two or more groups arriving at a similar location. A good example is this week at Overland Expo West. You could have 5 guys or 5 groups of guys converging on Flagstaff from different directions or leaving at different times. While in transit, folks could communicate and divert resources as needed if someone breaks down randomly somewhere. Google searches on an old iphone 4s (which I know some people still use) for torque specs on broken suspension components are a real pain in the a**, but a quick quip over Zello, or similar, could be really useful to someone in your group that kind of hoards that knowledge. It could even to be someone that stayed at home but wanted to be part of the team or could help do last minute Amazon shipments to your hotel or shop you're arriving at in Flagstaff.
How to utilize the communication, that's really up to you.
AT&T offers a Sonim XP8 with a dedicated PTT & SOS buttons. Verizon has the Kyocera Duraforce Pro with a dedicated PTT button. I've looked at them before mainly for their weather resistance.
For the emergency situations you mentioned Zello was optimal. Everyone pretty much has a cell phone and had the necessary equipment in hand already, there was infrastructure in place to support it, and access could be granted to people without special licensing requirements. Necessity favors network PTT as the solution.
Assuming that network PTT was your primary communication method you'd still need an alternate communication service in addition to it anyway because we like to go find places that generally does not get cell service or perhaps intermittent. That alternate communication service is now required. The network PTT becomes optional and the general trend would be to move away from this service as a primary method of communication. Necessity doesn't favour network PTT here.
Yeah, the Sonim XP8 is pretty cool esp for FirstNet, but most folks are going to stick it out w/ an iPhone or a Samsung Galaxy because they look nicer. As a work/secondary phone, I'd definitely pick either an XP8 or a DuraForce. They're even great to use at conferences, conventions, or big expos w/o being overly obnoxious.
During Harvey, folks were using Zello at the Dispatch centers (mostly female or male nurses in their kitchens from across the country after their shift) to help coordinate with the Cajun Navy. The ad-hoc rescue groups had all sorts of radio equipment in addition to their phones (which were intermittent in flooded areas) from FRS, GMRS, Marine VHF, CB, Ham radios, and some first responders using their VHF, UHF, P25 or other Trunked systems working with the Zello groups. It was pretty crazy.
But yeah, I'd prefer to use Zello on a TM8 at home and through a handheld on the road or on location. I suppose something I could do in a Zello only situation is to create multiple groups for trash talking and not have to be wary of any eavesdropping.
