I'm wondering what plus & minus the "Rework
Eliminators" would buy me?
The Rework Eliminator does exactly what the name implies. If you chose to
install them at the time of building then you can add K2 options at anytime
by simply removing the unmodule and plugging in the option. It eliminates
the necessity to tear the K2 apart an remove some components and install
others. With the KSB2 you have to remove the control board remove the front
panel and remove the front panel circuit board from the actual panel which
requires the removal of all knobs and then install the trnasistor a couple
of resistors and several capacitors and a diode and the 16 pin connector on
the back of the board. This means soldering in so very tight quarters to
install this connector. Also it requires the removal of two jumpers and a
.001 capacitor on the RF Board. This requires that you remove the botom
cover. The Noise Blanker requires that you remove three resistors from the
RF board and a jumper and reinstalling a resistor and a jumper. The KPA100
option requires that you install a power connector on the RF board in a area
under the Heat sink so it requires the removal and replacement of the heat
sink which is a tricky operation and can lead to a shorted final transistor.
The 60 meter option and the K160RX also require the removal of the Heat
sink. The 60 meter option requires the installation of a couple of
capacitors and a run of rg 174 coax and one end is connected under the Heat
shield. I have installed them in one K2 that I built for a fellow in
Virgina and I highly recommend the instal of them at the time of the build
if you plan to install the options at a later date. If you plan to install
them at the same time as you build the K2 then they are not needed as you
can get the parts needed from the respective options as you build the K2.
