Motorola MC68HC908KX8. Sorry, haven't got all the labels straightened out
yet - especially for the custom symbols. It's an HC08 family part, a
descendant of the HC05 with a 16-bit index register. It's got about 8k of
flash and 192 bytes of RAM. It's probably $2.50 more than the PIC used by
the TT3, but I think it's generally more capable. In any case, I don't
like the PIC architecture.

Power poles will handle 48 volts. and not arc. The are used on 125 v ac in
a lot of places. I just don't understand why go to 42 volts instead of 24
or 48. 24 v has been standard in the military for ever.. 36 v on electric
golf carts and some other wierd things. Even most of the big trucks are on
12 volts now instead of 24. The electric cars run as high as 150 volts. All
you gain is smaller wire, which makes every thing else smaller and lighter.
Any way that 42 v thing buggs me as why that particulay voltage, unless it
is political. And the more cells in the battery pack the more potential
problems you are going to have.

Really it is 36v.
The 42v comes from the 14v fully charged voltage of a 12v battery.
3x12=36 ; 3x14=42
The reason for going to a higher voltage is to reduce the current that is
being drawn and hence reduce the losses (and potential for fire) in the
vehicle wiring harness.

Subject: A Low-Tech APRSteward Proposal [was: SMART digi paths]

The "SMART digi paths" proposal seem to have two components:
#1 being a good network neighbor within a LAN, without knowing what the
acceptible UNPROTO settings for that particular LAN
#2 reaching a particular class of client/network appliance within the LAN
without knowing the best/shortest path to take to get there
Stepping back though...this begs the question, "since both of the facets of
the proposal include the phrase 'without knowing...' wouldn't such a
proposal be unnecessary if we would simply tell our users the information
that they seem to lack?"
Try this on for size (as a concept, don't pick apart the details):
Each LAN identifies a SINGLE digipeater AT ALTITUDE (greatest coverage) and
configures it to cyclicly TX LAN information as a BLN: to the area! This
proposal addresses the #1 question that APRS newcomers have: "What's the best
path to use?". When they ask it "on SIG", the answer becomes: "Power up and
lurk for 1-hour, then read your BLN's".
LTP 2 ID VIA WIDEn-N (where n & N = LAN hop count + 1 or 2 more)
LTP 3 ID VIA WIDEn-N (where n & N = LAN hop count + 1 or 2 more)
LTP 4 ID VIA WIDEn-N (where n & N = LAN hop count + 1 or 2 more)
BLT 2 EVERY 00:15:00
BLT 3 EVERY 00:15:00
BLT 4 EVERY 00:15:00
LT 2 BLN1:Unattended mobile stations use national standard: RELAY,WIDE,WIDE
LT 3 BLN2:In this LAN, all others should use RELAY,TRACE2-2 and TXD of 100ms
NOTE: ^-^
may be different for u
LT 4 BLN3:Be a good network neighbor - play nice or be SUPLISTed :)
-----Optional, but worth considering-----------------------------------------
LTP 1 ID VIA TRACEn-N (where n & N = LAN hop count + 1 or 2 more)
BLT 1 EVERY 00:30:00
LT 1 >GR##idS#PHGabcdef/ (this will display an "S-Star" icon [id-ing
the APRSteward] and providing enough position
ambiguity so as to protect your un-attended
asset's exact location...but being close enough
for 'normal' APRS operation)

Hi All-
From the Space Environment Center on October 21st:
**** INTENSE ACTIVE REGIONS EMERGE ON SUN ****
Two very dynamic centers of activity have emerged on the sun. NOAA
Region 484 developed rapidly over the past three days and is now one of
the largest sunspot clusters to emerge during Solar Cycle 23,
approximately 10 times larger than Earth. This region, which is nearing
the center of the solar disk, already produced a major flare (category
R3 Radio Blackout on the NOAA Space Weather Scales) on 19 October at
1650 UTC. The region continues to grow, and additional substantial flare
activity is likely.
A second intense active region is rotating around the southeast limb of
the sun. Though the sunspot group is not yet visible, two powerful
eruptions occurred on 21 October as seen from the LASCO instrument on
the SOHO spacecraft. These eruptions may herald the arrival of a
volatile active center with the potential to impact various Earth systems.
Further major eruptions are possible from these active regions as they
rotate across the face of the sun over the next two weeks. Agencies
impacted by solar flare radio blackouts, geomagnetic storms, and solar
radiation storms may experience disruptions over this two-week period.
These include satellite and other spacecraft operations, power systems,
HF communications, and navigation systems. *****
You will notice aprs has all of the impacted systems. There is a major
storm predicted for today (Oct 24th). I modified Wxsvr this morning to
parse all space alerts, warnings, watches etc to the apparent "from
Call" of SECALT , and the message group is "SKYSEC". The Hourly indices
are still from SECIND. This is sent as an object near Boulder Colorado
with a "sun" icon and the solar information in the comment field. The
"BK" portion is the 3-hourly average Boulder Kindex - each digit
representing 3 hours beginning at 0000z. the scale is 0 to 9 with 5
being a minor storm- 7 being a major storm- 9 meaning put on your
tin-foil hat. The flux has jumped to 183 with the a index about 6 -
so there may be some good DX before the ionoshere goes haywire during
the storm.
