[K2] J1 and J2 on control board.

[IZ2NYY]

Hy to all! K2 6995 still on the road...i know i'm a turtle, but i like it that
way! I've just finished the control board and still not placed the jumpers
through J1 and J2 cause just today i received several options from elecraft and
also the KDSP2. I know that J1 and J2 will be the locations for male pin headers
to connect the dsp option and i also know that on page 22 of K2 manual is well
written " J1 and J2 (bottom side. These two connectors are provided for an audio
filter option (KAF2 or KDSP2). An audio filter should NOT be installed until the
K2 has been completed and tested". Well....but i also understood that when i
will be ready to install the KDSP2 i will have to desolder the jumpers on J1/J2
in order to solder the male headers. Now i was thinking: "What about installing
now the pin headears on J1 and J2 and place the jumpers on the back as usual
together with the pins of headers???" Is it insane as opportunity or not so??
And if good...i can solder all the pins of the headers for the moment or just
the ones necessary to place the jumpers???

Many thanks (hoping have been clear!!!)

  Pippo,

Put the headers in and bend up two pieces of cutoff leads to stick in
the headers rather than soldering the jumpers in.
