Bob,
I assume that since you're only interested in Chesapeake Bay, you have
sufficient coverage if you have an antenna for a digi up a hundred feet or
so? That is, somewhere has line of sight to most of the bay?
I guess for California, the comparable situation would be San Francisco
Bay.
You probably couldn't for instance, track an ambitious sea kayaker down the
entire Pacific Coast, using the terrestrial APRS network.
But the idea of using the ARISS packet digi is intriguing. Is it actually
working? Someone had mentioned that the Amateur stuff on ISS was shut
down, except for school contacts.. and there's no obvious place to go for
status on the ARISS page.
Jim, W6RMK

I may have missed most of this conversation, but I've noticed (monitored) a
number of ocean buoys around here (San Diego) using POCSAG...

Subject: [aprssig] Garmin Astro
I haven't been looking at GPS hardware lately, but saw something cool on
CNN that Garmin is displaying at CES - my boss went and didn't take me...
:(
The Garmin Astro.
http://www.garmin.com/astro/
It's a (dog) tracking collar and RINO like receiver. I don't see why it
couldn't be used for other purposes. Your kid might look funny with the
collar on, though.
I really wonder about it's utility in hunting. I've done a fair share of
bird hunting (even with Top Gun guys out of Howard, SD) and we've never
really lost a dog. A good reactive "beep" collar seems to me to be more
useful, especially with a group of hunters.
And I think in some states this may actually be considered illegal - the
use of radios to facilitate hunting. I personally consider it unethical
and unsportsmanlike. Fair Chase. Then again I prefer to bird hunt with a
20 gauge over-under, rather than some tricked out semi-auto cannon.
73,
Mark

I saw the astros on a thread in a different forum. The questions that
were raised there were
1.) It appears to be a VHF unit. What frequency are they tranmitting on?
2) and what frequency are they transmitting data on?
As far as anyone there knew, MURS (or whatever that is called) is the
only VHF frequencies that don't require licencing of some sort and as
far they knew MURS does not allow data transmision.
Anyone know the answers to these questions?

Subject: [aprssig] MURS
The FCC rules governing the Multi Use Radio Service (MURS) have changed
recently (November 12, 2002). The information below reflects the new
(current) rules.
The citations below in brackets [] are from the MURS Rules, Part 95 of
Title 47 of the Code of Federal Regulations, especially Subpart J. Click
here to go to the MURS Rules themselves.
In general:
* MURS permits the use of a variety of emission modes, but the most common
is analog voice using FM modulation. Data communications are permitted, but
the FCC prohibits image transmissions. [95.401]
* Very narrow bandwidth transmissions (maximum 11.25 KHz channel bandwidth,
with +/- 2.5 KHz deviation) are permissible on all five MURS channels. The
older +/- 5 KHz deviation signals (with a maximum 20 KHz channel bandwidth)
are also permitted (but not required) on the two upper channels (in the 154
MHz band). [95.631]
* The FCC prohibits continuous transmissions in any mode except by
"grandfathered" (former Part 90) business-type licensees. [95.631(j)]
* The maximum permissible Transmitter Power Output (TPO) is 2 Watts. There
is no limit on antenna gain. [95.639(h)]
* MURS is intended for short-range local communications. Antenna height is
limited to 20 feet above structure or 60 feet above ground, whichever is
the greater. [95.1315]
* Repeaters (stations that retransmit simultaneously) and store-and-forward
packet stations are not allowed. [95.1311]
* No license is needed. MURS is available for unlicensed business or
personal use as described in this discussion. [95.1301]
* Radios suitable for use on the MURS channels are now available from
dozens of different manufacturers, and are sold by several online companies
and by consumers electronics store chains.

I searched the FCC database and there is not been an FCC ID assigned so
there is no information on it. It does show on the Garmin web site that it
is VHF WITH a removable antenna!

Subject: [aprssig] Garmin Rino
Since the subject of Garmin was brought up today....
Has anyone looked at the current series of RINO radios? They have fantastic
mapping capabilities!
I wonder if anyone has ever approached Garmin about making a Ham version of
the radio....Or if LOTS of us requested it, would they do it?
I for one would LOVE to have a RINO in the UHF ham band! I'll bet that
would spark some new interest in RINO decoding!
Seems that RINO decoding has kind of lost any focus in the APRS world as no
new development has been done in a while. (Or not that I have seen or
found).

OK I'll bite. First of all, read my post again. I did not tell a single
lie in it. The plan we had was for MADIS data to be mined directly from
the input servers, not utilizing findU at all. That is the truth. I did
offer this opportunity to the CWOP guys. That is the truth. They turned
me down. That is the truth. That is the explanation. That is the truth.
Where are the lies in there? I'm sorry, I just don't see them.
To correct the information, though, when the IP address of the findU server
changed, the information was not provided to the Tier 2 sysop who was
accepting connections from findU. Therefore, it was impossible to have
findU connect because it was the "wrong" IP address. That is all that
happened. That sysop is no longer a part of Tier 2, and the other three
servers were always available for connections as well. That possibility
was never offered, but we have never done anything at Tier 2 to prevent
data from reaching findU.
I hope that clears up some of the mire.
