[Elecraft] KFL1-4 FYBO mod results

[Leo Starrenburg PA5LS]

Hello Listmembers,

just did the FYBO mod. on the KFL1-4, not so much because I will operate
near or below freezingpoint,
but to -hopefully- crank up the low output on 15m.

After the mod. the output on 15m is now more than 4.5 Watts on a small
sla battery, better then before !

The reason I keep trying to get the power up comes from the fact that on
the internal AA batteries the ATU doesn't tune on 15m, it gives low
power instead. Tomorrow I'll install the ATU again and give it a try on
both the internal batteries and a 13.8V supply.

The only thing I haven't done is to replace Q7, could be I have a "lazy"
one ?

73' Leo.
