This image of #5048 shows three items which

are not part of an “Option Ready” K2: 1) Ken’s

custom brass plate; 2) the “option supplied” hex

spacer which is very easy to install; and 3) RF-J5

(Aux AF) which provides fixed level audio for

digital modes. Although adding J5 requires some

disassembly and additional soldering, it’s not part

of an “Option Ready” K2 because it doesn’t relate

to the installation of an existing Elecraft

option.

The two large white (2-pin) connectors along

the right side of the RF board are P6 (Aux RF) and

P3 (Aux 12V). They are provided with the options

that mount in the top cover. P6 is particularly diffi-

cult to install in a completed K2 as it entails remov-

ing the heatsink.

Although the Noise Blanker standoff is the only

one required by our un-module headers, all four RF

board mounted standoffs are included in an “Option

Ready” K2 since their later installation requires dis-

assembly of the enclosure, and because (for the

K60XV and K160RX standoffs) this disassembly

involves removing the heatsink.

Additionally, it's quite likely that someone

selling a used option wouldn't bother to

disassemble their radio and remove these spacers

to include them with the option. (In contrast, the

KAF2/KDSP2 provided hex spacer is very simple

to remove, although many KAF2 and KDSP2

"sellers" fail to include it when selling these

options.)

Not included in an

“Option Ready” K2.
