[Elecraft] WTB: Option Ready rev. G Headers for K2

[Don Wilhelm]

  John,

Well, it is not as "neat" as the Rework Eliminators kit, but you can 
order and install all the headers for the various K3 options that you 
wish to consider.  In place of the UNPCBs, put a 4.7 pf capacitor 
between pins 1 and 3 of J15 (the K60XV option) and a jumper between pins 
3 and 5 of J13 (again the K60XV option.

For the K160RX, install the header and put a jumper between 14 pin 1 and 
pin 7.
For the KNB2, instead of W5, put a jumper between J12 pin 1 and pin 6 - 
wait until you actually install the KNB2 to change the resistors on the 
RF board.

For the KSB2, install the headers for J9, J10 and J11 - the put a bent 
wire jumper between pins 1 and 3 of J9 and J10 (in place of W2 and W3 on 
the RF Board.  In addition, do not install C167, but stick its leads 
into pins 7 and 12 of J11.

For the KAFT2 (or KDSP2), install the headers J1 and J2 and put a jumper 
between J1 pin 1 and J2 pin 1, and another jumper between J1 pin 2 and 
J2 pin 2.

Install the AUX RF and AUX DC headers on the RF board - KAT2 and KBT2 
options or the KPA100.

With those additions, you will be ready for any of the options to be 
plugged into the K2 RF Board - the K60XV will require some additions to 
the RF board when the K60XV is installed and the KNB2 will require that 
the resistors forming the -5 dB pad be changed per the KNB2 
instructions, but it will all work.

Cost equals the headers plus a few bent up pieces of wire to stick into 
the headers and serve as the UNPCBs.

73,
