(a side show)…

26. APRS, Maps, Events and Objects!
Dayton Hamvention

27. TRACKERS (should be two-way)
One-way APRS is not normally recommended. APRS is a Network. We want good 2-way communications among all participants for maximum utility.
Trackers have no APRS data display. So the receiver should be tuned to a beaconed Voice frequency so the operator can be involved in the Net!
One-way trackers are good for non-manned assets at large movement events.. Not as the only APRS asset for a ham.
Trackers may be his 2nd, 3rd or 4th unit for APRS support… not his 1st!

28. TRACKERS (Now are two-way!)
TT4 with $34 display and AVMAP G5 GPS

29. YAGtracker $GPWPL waypoint output string (map stations on GPS)

38. APRS Global CQ’s www.aprs.org/cqsrvr.html
We needed a CQ System for SCOUTS, JOTA, SATERN, IOTA, SCR and Field Day!
AE5PL responded with CQSRVR
Allows anyone to send a global message to everyone involved in an XXXXX activity
Just send a message to CQSRVR starting with CQ XXXX CQ XXXX message
Everyone who has sent a similar CQ XXXX message to CQSRVR will get your CQ
From then on, once you see callsigns, you message normally point-to-point
To limit load, only one CQSRVR message per 30 minutes is forwarded.
Can also be used any day, any time, anywhere! CQ CQ CQ CQ anyone around?
Can also be used for global GROUP comms if 30 minute timer is changed.

39. APRStt (Touchtone) (every radio!)
See aprs.org/aprstt.html
For WB4APR, the DTMF Sends: A9A2B42A7A7C79#
This is converted to an APRS packet on the APRS channel as:
WB4APR-12>APRStt,WIDE1-1:!DDM_.__N/DDDM_.__W$146.58MHz HAMvention
Puts you on global map near Hara Arena, with your immediate calling frequency, your Tone and your Echolink node number and that a Hamfest is going on.
That is everything you need to be known to the Global APRS system!
Exists since 2001 (in DOS w DTMF chip). Now we have a Windows Version! By W4PC
Also Needed in Echolink, IRLP, and some repeater controllers with a serial port!
APRStt and therefore 100% situational awareness of any Ham mobile or HT then APRS will always be a side show only used by 10% of any club or organization.
Other Positions: #B95*234*1D => Milemark #234 on Route 95, northbound

40. APRStt (special event) (every radio!)

54. APRS Voice Alert! *
(For all mobiles!)
Voice Alert is effectively 3rd Radio channel for the D7 and D700 APRS radios
By setting the APRS Band A to CTSS-100,
but keeping the volume turned up:
You wont hear any packets on *
But you will hear a voice call using PL-100 on
And you will hear* an occasional Ping packet if another D700 comes in line-of-site to you, like a proximity radar alerting you to local presence.
Great for long haul traveling and meeting other APRS users.

64. Off - Grid !!! NOT !!!
Forget your HAM Radio lifetime of experience….
There is NOTHING economical about battery storage !!!

65. Battery storage has four very major shortcomings:
* High initial and maintenance costs
* They cannot save up the 2X or 3X summer excess for winter
* They lose 30% of all energy in charge/discharge losses
* Battery Maintenance and replacement problems for life

66. GRID-TIE is what makes Solar Economical
There is no “buying and selling” of electricity.
* Grid Tie simply works by pushing your meter backwards when sunny
* And letting it run forwards when you use power.
* Unlimited storage capacity,* unlimited time*, 100% efficient storage
* (on annual solar cycle)

67. When the Grid Goes Down? Whole House Off Grid System $50,000
Cost per KwH during outages
$ /KWH
$250
With Battery
60 cents/KWH
OR! Backup =
On Grid 15 cents/KWH

68. Solar Power = Emergency Power
COMPLETELY DIVORCE any thoughts of “emergency power” from Economical power.
Solar power is for ECONOMICAL POWER
Emergency power has nothing to do with it whatsoever. (Solve that problem separately)

69. Solar Power *is* Economical
Look at it this way:
Keep $24,000 in a bank at 1%. Continue to pay $200/m for Electricity
* After 10 years, you have paid $24,000 with NOTHING to show for it
* And every year you have uncertainty in ever rising prices
Buy a $48,000 solar system now, ( With incentives, Pay only $24,000)
* Have maintenance free electricity for LIFE
* It is generating $2400/year return on investment (10%) for LIFE
* OWN this $48,000 energy system and all it’s equity for life
* After 20 years it is still producing 80% of today’s power! (and will continue)
