maybe usefull to see what happends if the GPS signal from a tracker/gateway or whatever is jammed.
probably not very legal, but , it will be only used under lab conditions

Recommend you dont do it!..would need to be in a faraday cage to be “lab conditions” and then tracker wouldnt get GPS signal anyway! V.Illegal but often used by ‘white van man’/delivery/logistics driver types who want to park up a for a while ‘off grid’ so their companies cant track them…one guy copped a shovel load of trouble (about a year back IIRC) when he parked up near a US airport (Newark I think) and switched on his Jammer and took a rest…he disrupted the Airports GPS system and ended up with a $50k fine and I think a short stretch…
nonono… relax Jeff
reach is between 2-5 meters , I expect one tomorrow I’ll let you know
(or next week with a drink 
)
1st one is on me - if the authorities havent tracked you down!
Think I mixed up some of the stories I’d heard but principle still holds:
maybe I should have bought this one… for annoying people in pubs

Wow even cheaper than the old G26s though smaller display - harder to read? 
At this rate we will find them given away in cereal packets! 
if your interested I can take one with me next week… bought a few
*idea is to get it talking to a laird rm-186 ??
the one you linked is not working with the special bootloader.
