The use of 144.390 MHz is intended only for international operations, such
as through satellites. It should not be used for special operations,
except
in very special circumstances. The primary use of 144.390 MHz is for low
signal operations. One of the reasons that most people do not hear
transmissions on that frequency is that they are commonly using FM, and
most
low signal operations are FM. Also the low signal people tend to transmit
at
lower powers and use much higher gain antennas than the APRS operators
use.
The truth is that we really have no idea if someone is using that
frequency.

With multi-station receivers using software defined radios and Digital
Signal Processing, signals just above the noise floor are potentially
usable. 

And I agree that the use of a transmit only device is a really bad idea.
Even with using timeslotting you will get collisions since the TT3 code
takes a little time after power on to synchronise. And then there are the
other people who are using the same frequency who may not be involved with
the same event.  

I have considered using the transmitter for one of my projects, and I have
two issues. First is that it is transmit only, and the second is that the
device is not frequency agile. Both of these are killers.

If you want to use it full time for APRS, the clash of packets will be an
issue.

If you want to use it for special events, no probs.

Actually the currrent 144.390 Mhz version suits me to a tee.

Cause when I fly it in a plane, it will not trigger off every digi in the
hood.

I think my callsign ( VK5JFK ) should come off the list Andrew, because of
the Txing over others.

How come we can't make these ?

Surely someone can makes PCB's and the module looks made by some mob like
radiometrix

Umm, Andrew remove me from that list really did not give it a lot of
thought
whilst I really liked the idea of having something stand alone discreet
just
for APRS that I could put away some where and more or less forget about it
I
can though see many problems for others by using one.

In a busy metropolitan areas just imagine the possible problems what half
a
dozen of these transmitting on top of others could create I can imagine a
receiving a few, possibly abusive, emails.

Take me off the list Andrew

Hello all,
I'm home today with the industrial version of the flu bug thats going 
around. I'm usually pretty resistant to it, but this has flattened me!
Consequently, I may not be thinking clearly ... it's the drugs!

I had a look on the Byonics site to see if I could glean a little more 
info and came across the "picpac" http://www.byonics.com/picpac/

Is this really what it seems? A complete software defined TNC with GPS 
interface and 16x4 line display? Will it transform my old '828 into a 
D700. Maybee it's just the drugs?

No probs guys,

Allen from VHS has been hearing you !

He has taken all this on board and is doing a re-think.

Just an intrerest gathering process.

He now knows we have a healthy interest in the need for such a device.

No commitment what so ever.

I am sure we can nut something out

Something around 8W
Something freq agile
Something avoids collisions
Something with TT3 or opentracker on the back end.
