O.k ... the KAM DOES submit a K and the delay is ticked ...
Here is a sample of the tnc.log ...
The line below shows that it is TX'ing (at least it shows "TX->" and then the
line below next to it in the "Display Packet Data" window) after I changed the TNCEXTRADELAY
to 2000000 microseconds ...
TX->ZS6XOX-10>APX204,WIDE2-1:=2612.15S/02815.28EyPHG8130Debian zs6xox at gmail.com 0739347438
TNC->MYCALL ZS6XOX-10
TNC->UNPROTO APX204 VIA WIDE2-1
TNC->K
TNC->=2612.15S/02815.28EyPHG8130Debian zs6xox at gmail.com 0739347438
The problem is that even though it shows the "TX->" part in the "Display Packet
Data" window, the red TX L.E.D does not light up ...

It is checked ... ;)

I went up to 2000000 ... nothing ... :( ... well not really nothing ... at least
I have a "TX->" now ... ;) ...
It would be improper for me to continue to pester this mailing list if the simple
answer to my problem is that the KAM is simply just too old and I am trying to
achieve something more experienced Hams before me could'nt given that this issue
has been discussed before as you have pointed out ...
So I guess for my own piece of mind there are 3 things I need you to confirm for
me ...
could you check if the pin-outs from the TM-271A to the KAM is correct here:
https://forums.qrz.com/showthread.php?483978-Kenwood-TM-271-to-Kantronics-KAM
... and can you give me a tried and tested way to confirm that the KAM is in
KISS mode (yes ... I followed the steps in the manual ;) ) ...
... and can you confirm that the setting on my KAM is correct (below) ...
If all 3 of the above are honky-dory then I know the KAM is not up for the
task and I can sell it on eBay for at least $5000 as an antique (any takers?) ...
