No, I use common sense and I Look at the front panel of the radio which is
in front of my face and I observe the BUSY indicator Signal Strength Bar
Graph. On the open road, there is plenty of time when the channel is
clear..

To really understand Voice Alert, how it works, what its good for, and the
ergonomics of how its remote control head puts everything you need safely
in front of your nose, one needs to have the D700 and be familiar with how
it is optimally used for APRS mobile.

Aren't the FT-1500m and FT-2600m transceivers configured in a way to allow
a TNC to be
My FT-2600M suffers from "low power" shut down.
This causes the CPU to CRASH, and all your programming is
LOST....hope you have the SOFTWARE & cable.
Not sure of the 1500M's performance mobile or packet.
My 2600M is a jewel for running packet..off of a POWER SUPPLY.
If you are on a battery, get ready for glich technology, that crashes your
radio when the voltage drops below 12.1?
Not sure what causes it, but if it's on a power supply,
full power is no problem, and won't shut down.
Mine is on 24/7 on a battery/charger system, but NOT @ full power;
only 10W level. 25W setting will eventually, crash the radio; due to power
source; FYI

It's not solution -- it's an opportunity. An opportunity to meet and
chat with new folks and make friends. It's an opportunity to make
even better use of equipment and resources we have.
Here's something that happened to me a long time ago -- before D700's
existed and before this VA idea was formally presented.
Late one evening I was watching the local APRS traffic
and noticed a friend driving from his parents home east of town back
towards his home in north Seattle. I knew his route would take him
through downtown Redmond not far from my apartment at the time. I
also knew this friend left the volume up on his rig so he was actually
hearing the packets on 144.39. Taking advantage of that knowledge
I gave him a voice call (gasp) on 144.39. He came right back.
We moved off to a different frequency, decided on a meeting place,
and had yet another late night coffee and rag chew session. The concept
worked. The network didn't crash. It was a good thing.

I use the 100hz on 144.39. Havent heard anyone yet. There seems to be a
lot of concern about something that is not a problem. If it is ever a
problem it can be solved. I also monitor 146.52 and 446.00. Never hear
anyone. If you are in an area where to many 100 hz is breaking squelch,
you can turn your volume down, like every one is doing now anyway.

KC6ETE-9 is on a 1500. Just finished a run from indy to moultrie ga, and
I'll likely be heading back in a few days.
No complaints.

I've not run it that low often, but I did run the veh battery flat twice
leaving other gear on, and the 1500's memory survived.
I have two in my system, the other one does SSTV.

Don't forget that, if you're mobile, you really don't want to have to look
down for a quite-small "BUSY" indicator on the panel of your radio... lest
you end up looking like all the other idiots that can't drive out there, or
worse...

I wish there was a way to disable/enable the packet connector on the
radio. Until I read the manual that's what I hoped the "Packet" mode on my
FT-1500 would encompass (amongst other things). I am using the same radio
for APRS and voice but on different frequencies. If I forget to turn off
the TinyTrak, I start beaconing on a voice repeater. Not a good thing to
do.

Not to be malicious, but this is my opinion..
What is "CU2QSO" anyway? For me, it looks like a callsign..
You know, CU2 prefix is assigned to Azores Islands, Portugal.
So, I suggest you choose another designation for your project or whatever..
Don't mess callsigns (even if they not appear to be) with other things
please..
Any comments? Direct it to my mailbox instead of the list..

Your opinion has been noted. Thank you for sharing it.
If you are interested, you may understand the term by hyperlinking to the
website of http://www.BEACONet.org and selecting the hyperlink for CU2QSO.
You will understand not only why it is called CU2QSO, but you will also
understand what it is capable of doing.
While we're on the topic of the Azores...can you tell me if there are any
2-meter SSB operators on any of the islands? I would really like to find
someone who would be interested in participating in some transatlantic
experiments using APRS on PSK31 on 144.131 USB next year. That is called
PropNET (not to be confused with what happens when powerboat pass through a
field of fishing nets). <giggle>
With any fortune, we will have a very high power PSK31 Probe (PropNET's
term for a stand-alone TX-only station) in the Caribbean Islands, with an
antenna pointed toward Portugal next spring. Anyone on-list know of a
mountaintop that would be willing to site-sponsor such a station if it were
provided at no cost?
Information on PropNET can be had through the same hyperlink above, or
directly via http://www.PropNET.org.
