[aprssig] APRS-B?

I’m impressed with the 500 mw transceivers on 433 MHz costing $20 or so and
operating at 9600 baud.

Why don’t we call this APRS-B (plan B).  And start paralleling our network
with these devices.



Then instead of only 5% of hams having APRS capability, we could get more
people in the clubs to own a device and also to put one up at home so we
have a backup data channel as well?



Maybe lots of you are doing this alrady and I am the last one to the
party.  But whatever we do, lets standardize on something so we are all
headed in the same direction.



These are wideband devices, so they are not compatible with any existing
APRS or other ham FM radios.  That is why it is a fresh start.  What is the
sync and key up time?



Sure the range of 500mw is small, but at only 10% of the cost of a digi we
can put them at more and closer places and even solar power them.
