OK, I give up! I've been searching the internet trying to find out how to
get the PK-12 out of KISS and I can't find the answer. Could somebody
please help?
Thanks,
Earl

According to my PK-12 manual, three CTRL-Cs will force KISS OFF. Whether
this works MAY depend on what version firmware your PK-12 has. The same
sequence is supposed to get it out of APRS tracker mode, but it didn't work
in mine when I had the original 7.0 firmware. When I upgraded to 7.1 it
worked as advertised. I seem to remember something else that didn't work as
the manual said until I installed 7.1 (BBSmsgs maybe?). Before I did the
upgrade, I had to reset it a few times by pulling the backup battery jumper.

Ok, I was just getting ready to burn a UIDIGI EPROM for the first time
(version 1.8), and I noticed that the BIN file is just a bit short of the
32,768 bytes required to fill a 27C256 EPROM. I would assume that the image
has to be aligned with the upper edge of the EPROM since boot vectors are
usually at the top of the address space. The FAQ and manual don't mention
that, though. It does say to use 8000h through ffffh when using a 27C512,
which would be 32,768 bytes. The image is only 32,407, though. What gives?

That worked GREAT, thanks!
I had tried three /'s, three \'s, CTRL-C, and everything else I
could think of...<G>

Greetings Scott,
Okay, think of an EPROM as a blank sheet of paper ... blank, meaning that
all bits per byte are high, i.e. FF hex.
Now, that blank piece of paper *can* contain 32,767 bytes or "letters", and
you want to write a note to your boss (say).
There is no law which requires you to exactly fill that blank page with
*exactly* 32,767 characters and spaces; just so long as you get your
message across to the boss.
The phrase "I quit !" has only 7 bytes, and it get's your message across to
the boss ! :)
Same thing with UIDIGI code, which I think is some 32,356 bytes; the "page"
is not full, but the message gets across (the program runs, in our case).
The rest of the bytes are like that blank paper, or FF hex (all bits high)
and ignored by both your irate boss and the CPU, in the case of running
code.
I hope this anolgoy helps, and that you can rest assured, that any program
does not have to fill the whole chip, to the last byte.

I just received a message on another mailing list that Pete Loveall AE5PL
suffered a fatal fall from his home tower. Can anybody verify?
If true, this is a tragic loss, not only for his family but for the APRS
community as well.

I understand that, but when the image is smaller than the ROM, the question
is where does it go. Chips like the 6502 and 6800 series require the reset
vectors to be at fffe-ffff, which means you usually have your ROM code
aligned at the top. Apparently the Z-80 starts at 0000, so it doesn't
matter.

Hi Scott,
Yes, that is correct ... in fact someone told me that "There is digital
logic and then there's Intel logic." :)
We're totally "upside down" when it comes to processing - the Motorola and
I think the Rockwell (Alcatel) chip set are the other way aroung. Intel &
Zilog start at or near the bottom and work "up"; where Motorola and Alcatel
start at the top and work "down".
Where this get really messy, is when you code at machine level; if you're
used to Intel/Zilog you have to do the logic one way; If you're coding for
Motorola/Alcatel chipsets, you have to "invert" your thoughts, the other
way around.
But not to worry, only a very few of us "code" at the machine level. (At
work, I'm no longer allowed to "code"); This is for your generation, not
mine. I'm told by senior management, that "my place" is no longer at this
level ... My place, apparently, is to pass in review the new systems and
technologies, and to then tell senior managemet (not how it works) but how
it fits in with our over-all business plan !
On a happier note, I'm 53 and have 30 years of service in the telephone
industry. Retirement, will be a few *months* away, I hope !
As always, vy 73 de John VE3NEC

, Could this be the truth? From the ARRL Letter * ARRLWeb
http://www.arrl.org/arrlletter
==>WELL-KNOWN CONTESTER, DXer DIES IN FALL FROM TOWER
Well-known contester and DXer Steve Miller, N8SM (ex-WD8IXE), of Prosper,
Texas, died June 15 as a result of a fall while working on his Amateur
Radio tower. He was 38. An ARRL member, Miller had extensive experience in
tower work and antenna installation. With the assistance of several other
hams, Miller had erected a 136-foot tower on his property and installed
several antennas as part of his overall effort to build a competitive
contesting station.
Details of the mishap that claimed Miller's life are not available.
According to unofficial accounts, Miller had been working on his tower the
morning of June 15, and, after a lunch break, told his wife, Radhicar,
that he had another hour's work left. Later, she heard a noise from the
yard and found her husband lying on the ground. Miller's wife called 911,
but the rescue squad was unable to revive him.
ARRL antenna guru Dean Straw, N6BV--who had corresponded with Miller on
several topics--was among those expressing shock and sadness at his death.
"Steve was always most responsive, and he always had the most intelligent
comments and questions concerning whatever technical topic we were
discussing," said Straw. "I will miss his innate, contagious enthusiasm."
First licensed as WD8IXE in 1977 at the age of 12, Miller--an Ohio
native--enjoyed contesting and DXing. He was routinely active during the
CW weekends of the CQ World Wide, ARRL International DX and ARRL November
Sweepstakes events. He also operated as J68AG from St Lucia in the
Caribbean and participated in a few DXpeditions, including several stints
as a member of the J6DX team in the 1980s and 1990s. He was an ARRL DXCC
Honor Roll member, with 332 entities confirmed (mixed).
In addition to ARRL, Miller belonged to the North Texas Contest Club
<http://www.qsl.net/ntcc/> and 10-10 International
<http://www.ten-ten.org/. Besides ham radio, he enjoyed playing jazz
saxophone.
An Ohio State graduate, Miller worked for Texas Instruments as part of its
broadband wireless access group in Dallas. Survivors include his wife and
their young daughter. A memorial service was held June 19.
