Hi all,
It turns out that pin 17 on U2 has an undefined voltage.
When NOT selected that band (40/30M) it must be 12V. I measure 7V.
The input for this switch is pin 2 at U2 Here I measure 0V (=good) and
goes HI (5V) when selected
So U1 is working well
Will heading tomorrow for a new U2
Hi
After a few years of good service,I have a problem with the K2 output.
I have the K2 with K2/100.
The barefoot K2 put full power out on all bands via the bnc connector
When I connect the K2/100 with PA off with the menu there will be low
power on the ant connector on the higher bands
Peter,
The fastest way to determine if you have a problem with the Low Pass
Filter in the KPA100 is to check it with an antenna analyzer.
Disconnect the small coax to the K2 RF board and terminate it with a 50
ohm (51 is OK) resistor. Power only the base K2 (the ribbon cable must
be
3 matches
