I bought a TT3 from Byon at Dayton and asked him this exact question.
His reply was the (at least with the 3) the passthrough pin that
provides power to the GPS is a a pin that is normally asserted High
anyway when connected to a computer RS-232, or is no-connect in some
situations. If your TTII is wired the same as a 3, then you should be
ok. Check your wiring against a TT3 from the manual from the website.
After I get my 3 built, I plan on doing this to power my older Tripmate
with one cable.

I had the pleasure of meeting and talking to Gerry on several occasions.
He will truly be missed. A lot of people probably interacted with him at
hamfests without knowing his name, but he was the fellow with the white
beard and the Arrow antenna. He's the reason I own one. :)

When we at NASA / Ames flew our Mars airplane prototype from 100,000
+ ft., from Tillamook we had an APRS tracker on the balloon and the
airplane. The contractor, GSSL, had a chase plane in the air
monitoring both channels, which were separate from the digipeater
frequency . When the FAA wanted a position report, the chase lane
reported back directly.

I wouldn't be surprised if it used the same NMEA sentence (GPWPL) that
allows received APRS positions to appear on garmin GPS's:
http://www.hulleng.karoo.net/g0vrm/content/aprs/garmin.htm#waypoint
This way, having the rhino hooked up to a computer would allow you to
see your friends on that map. Should be fairly trivial to decode that
sentence and make it as an object tx'd to the aprs side. just need an
extra serial port for the rhino.
could use the standard SSID translation for the symbol

The "standard" I use is "power on pin 9". DeLorme uses this for their
Tripmates.
Generally, you have to use a null-modem adapter to connect a TinyTrak to
the computer serial port for programming. I built my own and don't have
pin 9 connected, so the computer doesn't see the V+ I put on the TinyTrak's
pin 9.
The GPS-35HVS doesn't need regulated power, so you can tap directly from
the 12V input. I use a GPS-35LVS (low-voltage version), and I installed a
separate 7806 regulator to feed 6V to the GPS. Using a 7806 instead of a
7805 should cut the heat dissipation problem a bit, and there's anecdotal
evidence that the Tripmates I also work better with 6V than 5V.

James did not say the preferred home path started with RELAY. He said
"Please use the following Wide2-2 or Wide3-3 if your able to get into a
digipeater direct. If not than use Relay,Wide2-2 or Relay,Wide3-3." Note
that RELAY is recommended ONLY if the station cannot hit a digi direct.
Now I expect that the circumstances that would call for a home station to
use RELAY are uncommon at best, but certainly not impossible to imagine.

Hi Bob,
I have observed in more detail, as I promised, listening for VOICE ALERT
PL100 here in Athens area for a few days now with both my TH-D7 and TM-D700
and I noticed the squelch breaking a few times. Sometimes I can hear whole
packets and sometimes half packets. The D700 is not as bad as the D7 in
false openings of the squelch.
I suspect that the half packets I heard are due to reasons different than
either normal opening of the squelch due to the 100HZ subtone that some
stations use. On the other hand when I hear whole packets, sometimes
decodable, I believe that either the operators use 100HZ on TX and I lost
their packets or they are base stations operating on mains PSU, probably
badly filtered, and the 2nd harmonic of 50HZ breaks my squelch. I heard and
decoded some DIGIS that way so this probably means that whoever said 100HZ
is a bad idea for Europe might be right! I never decoded any mobiles that
broke my squelch.
From now on I will try another setting, i.e. 162.2HZ and see what happens!
This is definitely not any harmonic of our 50HZ mains frequency.
I will keep you posted!

Good idea and then you can see if the squelch opens any more...

Since this has raised some questions on the SIG here are some basic
guidelines:
BIOS Dated August 1994 and before supports drives to 528MB
BIOS Dated September 1994 to February 1996 supports drives to 2.1GB
BIOS Dated March 1996 to December 1997 supports drives to 8.4GB
BIOS Dated January 1998 to June 1999 supports drives to 32GB
BIOS Dated July 1999 and later supports drives to 137GB.
YMMV. There are some oddball combinations out there. And some OEM's were
ahead of the pack in drive acceptability. I have run across OEM systems
that only support the drive combinations offered by the manufacturer at the
time. Some computer systems, like Compaq, were still using BIOS setups
that required software up to the PIII era. If you replace your main drive
without putting the setup utility on it's own little drive partition, you
may end up with a problem later...
Current standard ATA/IDE interfaces uses 28-bit addressing and to use a
drive over 137GB one needs to make sure his IDE solution has 48-bit
addressing.
Also note that I have experienced problems with several ATA 100/133 drives
UNDER 137GB in size on current ATA 33/66 controllers and BIOSes, including
lost partitions and scrambled data. I would recommend that if you decide to
put a big high-speed drive in an ATA 33/66 machine that you purchase an
add-in IDE controller card like those made by Promise Technologies (Promise
Ultra-133 TX2). Leave your CD/DVD on the onboard IDE controller or you
may have problems booting to a CD ROM if you need to. This card also
allows you to break the 137GB Size Barrier. Do not put those 160GB+
drives on an IDE solution without 48-bit addressing, even with BIOS overlay
software, you will lose data. I lost about 15GB of rare and out-of-print
music (Kay Kyser, Lionel Hampton, etc...) converted to MP3 that way...
If you are building a new computer these days I would seriously recommend
looking into Serial ATA (SATA) hard drives. SATA DVD and DVD-recordable is
on the way. CD's and CD-R's are on their way out so we may never see an
SATA CD drive... But you can always use that ugly, flat,
hard-to-deal-with, parallel IDE cable for that.

Mark
