k2 t-r external relay driver board
This
K2 T-R External Relay Driver Board is a fully kitted
version of the latest design by Tom
Hammond, N0SS (SK). Everything needed to take the
K2's internal 8R signal for an external keying line, and
bring it out to a rear panel mounted RCA jack is included
in this kit.The K2 T-R External Relay Driver Board is perfect for externally keying an amplifier or external relay circuit allowing the K2 to drive and amplifier. It uses the K2's internal 8R signal from the J13 socket (used for the now discontinued K60XV module). an IRF630 QFET is used as an open drain output and is pulled to ground during transmit.
I
am offering this board as a full kit or as a built
unit ready for installation in the K2. See pricing
options below or on the order
page. If you would like me to build and install
this board in your K2, please contact me at info
-at- w8fgu.com for a quote.
For information on the circuit and operational instructions, please read through version 2.4 of the document published Tom in 2011.
Note: there is a wealth of information available of Don's website as well as Tom's
website presently preserved by the Mid-MO
Amateur Radio Club. If you are a K2 owner, these
are valuable resources relating to building, servicing
and great add-ons for the K2.
