I'm glad that it's finally getting data, but I'm a bit disappointed in the quality of the unit. Whereas the Garmin got signal almost instantly, and the Inventek could take a couple minutes, the Lassen took quite a while, perhaps up to 10 minutes (I didn't keep track). More worrying is that it only sees something like 4 or 5 satellites, whereas the other two units would see around 10 +/- 2 when they had signal.
I'll try using some scrap sheet metal to make a better ground place for the antenna, hopefully that will increase reception. Also the unit will have somewhat fewer obstructions as it flies through the air, but still, it would be less worrying if it didn't have such a weak signal to begin with.
