haven't come across this problem, but I haven't used 220KISS for quite a while.
I think I still have a TNC220 somewhere - I'll try to dig it
out.</FONT></SPAN></DIV>

<DIV dir=ltr><FONT size=2>Hi All...</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>Does anyone have any informaton re the KISS only rom
image "220KISS" for the Pac-Com TNC-220 ?</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>I have just tried it, and though it receives well,
it often transmit's a blank signal, that is, it keys the radio, but send no
audio, that about 50% of the time. When it does transmit audio, often
it's truncated at the begining of the packet. When it works though, the
packet and data are good.</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>The hardware is fine, the TNC-220 and radio
(FT2700RH) are time prooved and work well.</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>However due to a strange issue between UiView and
the original TNC firmware 1.1.5 and 1.1.6 and it's KISS implementation, I was
getting overlong transmit preambles, like at least one second! But the
data payload was good. Hence at someone else's recomendation, I went
looking for this. Google for "220KISS" (no quotes) and you'll find
it.</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>In regular packet mode with the original
firmware, the TNC works OK, no problems at all.</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>So, looks like a bug in the 220KISS code?
Anyone know of a copy of the sources, I have Z80 cross assemblers to
hand.</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>I believe it was in part crafted by G8BPQ.
Anyone have any contact details for him?</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>It may be a "Bit Old" though.. V.32
26MAR 87 can be seen in the rom image starting at address
0003. The size of the image is 2k (2048 bytes)</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>Anyone got a newer version?</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
