[aprssig] futurelec modules?

It looks good Chris.

My only warning is that the timing sucks very badly-using it for a 
GPS based frequency standard WOULD NOT even begin to work. For 
position only reports, it should work fine.

Be aware also that the current consumption does not include the power 
for the active antenna and since GPS signals are not strong, an 
amplified antenna is a must, not just 'optional'. Typical mmic based 
preamps use 20 ma or just a tad more, I'm looking for an appropriate 
mmic preamp for my module now and homebrewing one DOES NOT seem to be 
an option::>

Many find the external antenna to be a plus rather than a detraction 
as the difference in performance is much better with an external antenna.

Regards,

Art
