Gheem on "The Rocketry Show" podcast #88 mentioned the AIM XTRA GPS/Telemetry/Altimeter package from "Off We Go Rocketry." Checking on their web site, I see only the 2.0 hardware version currently available for sale--but Gheem mentioned a newer 3.0 version that is now available.

Off We Go Rocketry
Reading through the description and manual, this seems to check almost all of the boxes that I'm looking for to complete a telemetry project. Until now, I've been improvising a similar solution using a modified APRS balloon tracker to transmit real-time telemetry information to my HT. While this works, it makes managing the data downloaded difficult at the ground station.
The AIM XTRA system seems to resolve many of those issues, and it operates on 432 MHz at 50 mW--perfect in terms of range.
I'd love to hear from anyone who owns the system. Gheem mentioned that it's possible to have voice announcements in real-time, another plus.
How reliable are the altimeter/pyro settings for the device? What is the minimum diameter rocket that I could loft this thing in? What type of connectors for the antennas? (I'm assuming SMA). Anyone tracked the rocket using a Yagi or small Log antenna? I was thinking about an ELK or Arrow antenna as an option for greater range.
