Although I appreciate all of your answers I specifically asked these
questions of Wayne because I was making a point to let him know of my
disapproval of the fact that the KXPA100 amp is incapable of running a
full 100 watts on a standard 12v battery. Furthermore I was trying to
get an explanation from the head designer as to why my amp that has a
30amp power supply at 15v (read on the KX3) or 15.4v at the input is
unable to transmit at a full 100 watts on all bands. Yes, I have the
supplied cable with fuses attached, it's only 3 feet long, and the
transmit vs' receive voltage is less than a volt difference. So all of
those bases have been covered. As noted I have also completed the KX3
power configuration, and the KX3 to KPA matching alignment procedure...
I was alluded to the idea that there were a second revision of boards
that came out for the KXPA100 after the early models were shipped. I
have also heard that those boards help increase the output power.
Therefore I was asking WAYNE if this were the case, and perhaps having
them would help this situation. As for the 12v not running the amp, this
IS an issue because at field day we have 150 Ah batteries that run 12
volts, and it would be nice to have my 100 watt amp run a full 100
watts. Again, this was designed as a portable amp. I would expect that
at 12v we should be able to get the full rating out of it.
On another note, what may have also gotten lost due to all those trying
to be helpful, but cluttering my original post. I have a K3 that no
longer puts out 100 watts on 17 meters but does on all other bands. I
was told this was a software issue by Tech Support. I would like
confirmation FROM WAYNE that this is the case, and when he may have time
to address it. If not, I would like to know why I was told this.
So again, as much as I appreciate all of you trying to help with these
questions, I would much prefer that Wayne address them personally.
Thank you,
