Sorry if someone has already suggested this, but I'm way behind on catching up with my email right now. I'm not sure if the cause of what you were seeing is because of what the GPS is outputting or because of algorithms in the T2. How about trying some semi-SmartBeaconing? You could set the fast and slow speeds both to e.g. 10 mph with both set for a 3 minute beacon rate. You are presumably running low power while on foot, and if you use a reasonable path, and keeping in mind that you won't always be heard, you wouldn't be creating too much QRM. Then use your slightly more aggressive settings for corner pegging. I believe some airborne APRS users have used the technique, but not always with otherwise optimal (path) settings. On a plane, profile switching would really shine to change the paths e.g. > 5000' and < 3000' on the way back down, with those figures adjusted depending on the kind of terrain where they are flying. 73 es cul - Keith VE7GDH -- "I may be lost, but I know exactly where I am!"
