[aprssig] Thinking about YAAC

Well, the Kenwood port was a bit unsuccessful. I can't change port
types, I have to delete and create a new one. So, I deleted the
Serial_TNC port and created a Kenwood port. Still no received data
displayed. I tried to go back and check the TEST PORT to see if data was
coming through, but as soon as I click on the Kenwood port in the port
list, the program locks up. I have to go into a terminal and kill the
process. Now I cannot delete the Kenwood port without crashing YAAC.
I looked at the RAM chips and the numbers on them do not come up in any
cross reference or data sheets. However, I did find some references that
said if there were two chips it was 8K and if there was only one chip
it was 32K. Since there are two chips, I am assuming 8K, so I ordered
the 32K upgrade along with the firmware upgrade from TAPR.
Please be sure to announce the new groups.io forum here when it is set
up so folks can sign up. Groups.io changed their policies a little while
ago when Yahoo started falling apart. They used to have a great free
transition tool that moved files, members, etc. from Yahoo to groups.io.
Now, that tool does not work as well and they charge a lot for it.
Easier to just ask everyone to resubscribe to the new list. Weeds out
all those people who subscribed and never came back.
Good luck with the lights.
