Hi Geoff (of Kiwiland),

Thanks for the information and testing. Having had my 3.50 18x and 
NTP report that NMEA time is -1.00 seconds compared to PPS time, 
I'll give 3.20 a whirl.

I've certainly bricked my share of devices by attempting to 
"reverse the timeline" of firmware images. Manufacturer's have 
cavalierly deemed  such attempts to install an older firmware image 
as being "unsupported". I tend to think of it more of as programmers, 
for reasons as diverse as lack of time, talent, technology, or 
imagination, who create insufficiently robust installers.

It's very nice of you to actually test going from 3.50 to 3.20 for
the rest of us.
