WGARS 2020 - APRS and APRS Satellites Portable operations and Energy
APRS Satellites Human to human info exchange! Outernet Geo Sats APRStt !!! Kenwood D74 news Energy
May 2014 1 APRS – The universal Info Channel
Anywhere on Earth tune to the APRS channel and monitor for 10 minutes and you should collect info on what everyone is doing right now in Ham Radio. - Where they are - What they are doing - On what frequency - Announcements, Bulletins - Messages to-any call anywhere on earth - etc APRS – The universal Info Channel
So you tune in, and nothing is there! (APRS.FI) BECAUSE NO ONE IS PUTTING OUT WHAT THEY KNOW Ham Radio, Emergency Ops and Energy!
Emergency Response depends on Power & Energy! It’s a whole new world of Power

5 WB4APR (APRS)
Field Day* * * Satellites 6 240 Watts for portable operations
Gains 30 mi per week If you want some SERIOUS portable power, Think EV! Every hybrid has 50 kW generator
A plug-in EV has from 16 to 85 kWh of Battery Storage! And can power a house for a week or a month
8 EVs can power homes during blackouts
Power out? Power your house From your Car!
EV’s don’t wait in gas lines
Bob Bruninga, PE IEEE Transportation Committee http://aprs.org/payin-to-plugin.html 9 SERIOUS Battery power
Leaf 40 kWh
3 year old off- lease used is only $9,000
Bolt = 60 batts Same as 3 Tesla Power walls costing $21,000 10 SERIOUS Generator Power Plugin Hybrids = 50 kW generator
Prius
Plug-in Hybrids have at least 50 kW generators.
Can power a house for a week or a month Chrysler Pacifica Minivan Same as 1 Tesla Power wall costing $7,000 + Generator! 11 Solar and EVs – The Perfect Marriage 12 Prius
plugin Pacifica Minivan 40 mi/day
No more $2,000,000,000 per day for overseas oil No more foreign dependence, no more price fluctuation No more oil, no more insecurity, no more oil wars Now ten years into the EV revolution
There are 62 models on the market from every manufacturer
AND
They are Better, Faster, Cleaner, Safer, Quieter
AND
Cheaper to buy (with incentives) Cheaper to Operate (half to a 3rd the cost of gas) Cheaper to maintain (10%,compared to a gas car (tires, wipers and blades).
AND you never have to go to a refueling station since you leave the house every morning with full range EVERY DAY.

High efficiency prices ONLY go up since the space industry will pay
2 times Cost anything for each better 1000x additional 1 percent. more
Home panel prices only go down since homeowners will not buy anything but the cheapest So much about Energy and Ham Radio! Electric/Solar Transportation Forever!
