[Elecraft] Hmmmm Help .... Micro KEYER II & K3S

[Joe Subich, W4TV]

microKEYER II interfaces to both the K3 and the K3S the same way.

With the K3S one uses the Elecraft supplied E98027 cable between the
RS232/P3 (RJ-45) jack and the XCVR jack of the P3 *as shown on page*
*19 of the K3S Owners Manual*.  The RS-232 plug from the DB37-EL-K3R
or DB37-EL-K23 cable connects to the PC jack of the P3.  If you do
not have the P3, connect the RS-232 plug from the microHAM cable to
the DE9 connector of the Elecraft supplied E98027 cable.

*DO NOT USE* the Elecraft CBLP3Y cable and USB connection on the K3S.

The +13.8V (power) plug connects to the "switched 12V" output of the
K3/K3S (and the DB37PWR jumper in MK II is set to power from the cable
instead of the +13V jack - per the microHAM Users Manual).  Line
In/Line Out, ACC, PTT, Mic and Key plugs attach to the matching jacks
on the K3/K3S.  Note: the K3S should be configured for RS-232 and
*not* USB as documented in the Elecraft K3S Owners Manual.
