[Elecraft] Re: KPA 100 pA issues,,,, puzzle...

[Bill NY9H]

initial symptom was the autotuner would lock up/ & reset the 
radio  when tuning ...only on 40 , so I ordered the PA upgrade kit...

when running the k2 @ qrp .. the swr reads correct and the PA is 
basically out of the circuit,.,,,,"1.3"  ....  this is on 40. both on 
the set AND THE LP-100

now my LP100 is giving me a big clue what is going bad in my K2/100 PA.....
The problem is that I still don't understand enough of the basics../..
but when i dial up over 15 watts  the swr reads 9.98  !!!  but when i 
go back to under 15 watts .... the swr reads correctly...(LP-100)

I know something is wacky in the kpa100....  and i thought it was in 
the tuner...

I have just completed the last of the upgrades to the KPA , but it 
appears to not have helped...

oN TYHE k2/100 the swr seems to read double when on the  PA  vs the 
qrp,....on the other bands , but 40 has bigger /*issues...such as 
locking up the autotuner... .which was the original sympton...

on 20 ,,,ssb   xmit on , no modulation.... I get 9.9 swr on the 
lp-100 ...but when i modulate i get the real 1.6 swr ....

and on the dummy load everything is fine ,,,,,,& none of the other 
radios including another k2/100 split in a EC2 case have problems 
with the antennas....


AND I WAS WANTING TO START MAKING CABLES FOR THE K3....
