<p>YES! UIview has a meteor mode. When linked to the UZ7HO
Soundmodem soundcard soft TNC, it would do exactly what you
want. The Soundmodem connects to APRS clients either via the
AGWpe IP interface, or via KISS-over-IP. <br>
</p>
<p>In fact, if you only want to monitor, the Soundmodem has a
built-in receive-only terminal window that displays packets heard
& decoded -- no external client required. <br>
</p>
<p> If anyone is interested, I have a complete turnkey UIview setup,
including mapping and the UZ7HO Soundmodem packaged as a
ready-to-run VMware virtual machine. This VM can run on any
platform that supports the freeware VMware player -- i.e. it can
run on Macs and Linux as well as Windows. This is available for
download on my website.</p>

<p>1) If this is done on the usual 2-meter channel, one is also
going to copy a lot of normal local APRS traffic as well. We
should probably agree on a single nationwide ALTnet destination to
be able to filter out everyday local activity.</p>
<p>2) Should this even be done on 2m? I thought meteor propagation
was far better on 6 meters. Also, on 6 meters, one could take
advantage of the large number of 100-watt output radios. Many
100-watt-out HF rigs also now do 6 meters. Not to mention the
all-banders such as Icom 706 series, Yaesu FT-100/857/897, Kenwood
TS-2000, etc that put out 100 watts on 6 meters.<br>

<p><font face="monospace"> Meteor Mode Setup</font></p>
<p><font face="monospace">UI-View32 Meteor Mode is a special mode in
which the program can be used to transmit beacon frames very
frequently. It is designed to be used for meteor scatter
propagation tests.<br>
<br>
Two different modes of operation are possible - "Interval" mode
and "Burst" mode.<br>
<br>
Interval Mode - A single beacon frame is transmitted at a
specified time interval.<br>
<br>
Burst Mode - Beacon frames are transmitted continuously for a
period of seconds. You can specify how long the burst should be,
and when you want it to start in terms of the number of seconds
into each minute.<br>
<br>
Port - The port on which you wish to use Meteor Mode.<br>
</font><br>
<font face="monospace">Unproto address - The address to which you
want to send the beacon frames, including any digis. The
destination address and digis should be separated with commas,
do not used 'V' or 'VIA'. Examples - CQ would address the beacon
frames to CQ, CQ,RELAY would address the beacons to CQ via
RELAY.<br>
<br>
Beacon - The text of the beacon you want to send. For meteor
scatter use, the beacon should be as short as possible. The
shortest beacon that can usefully be interpreted by APRS
software is probably your IARU locator surrounded by square
brackets, e.g. "[IO92XX]", and that is the beacon you are
recommended to use.<br>
<br>
NOTE - The following four automatic beacon input buttons cannot
be used until you have input your latitude and longitude in
Station Setup.<br>
<br>
Grid - Automatically input a grid square beacon.<br>
<br>
Grid-in-status - Automatically input an APRS "grid in status"
format position beacon.<br>
<br>
Posit - Automatically input a normal APRS position beacon.<br>
<br>
Comp'd - Automatically input a compressed APRS position beacon.<br>
<br>
Interval (only used in Interval mode) - The interval, in
seconds, at which you wish to transmit a single beacon.<br>
<br>
Start (only used in Burst mode) - The number of seconds into
each minute at which you want the burst of beacon frames to
start. You can specify more than one time, e.g. "0,30" would
mean "start a burst at 0 seconds into each minute and another
burst at 30 seconds into each minute". If you were conducting a
trial with someone, then they might specify "15,45", so that
your transmissions interleaved.<br>
<br>
Duration (only used in Burst mode) - The length in seconds of
each burst of frames. UI-View converts the specified duration
into a number of frames to send. The calculation is accurate,
but it makes two assumptions - (a) that you are using 1200
baud, and (b) that your TNC will transmit continuously when fed
with a stream of frames. If your TNC releases the PTT every few
frames (the TH-D7 appears to behave in this way.), then you will
need to make allowances for it, because a specified duration of,
say, 10 seconds, will result in an actual burst length of
perhaps 15 seconds.</font></p>
