[amsat-bb] Tutorial on Working APRS Contacts on Kenwood TM-D710

[Robert Bruninga]

I guess the difference is that I was thinking in terms of efficient
channel use while making a demo contact or so.  It does take more work.
But if your goal is only to make a demo contact, then it is easy enough.

On the other hand, those trying to maximize contacts per pass will find
messaging easier, though adding a significant load of ACKS on the channel.
Fortunately,  Patrick's guidance does attempt to manage that.  The key
being, to CANCEL a message as soon as one knows it has been digipeated and
NEVER wait on an ACK.

Say the channel is running at 25% success, then the chance of an ACK is
25% of that or only 8% or meaning the ACK might need 16 transmissions to
be heard. (though the APRS radios stop at 5).

To answer Greg's question, the first press is Menu,  Select APRS, Select
status, Select number, Select Rate, begin editing.  But all of those are
already in line since the last time it was used, so it is just 4 rapid
presses of the SEL (ok) key. But then you have to manually enter the other
persons call (while remembering it).

Hi Bob,

For those of us with a non-D710 radio (e.g. the D74A), what are those 5
menu items you're pressing through?
