[Elecraft] Connect KPA-500, TS-480 and MicroKeyer II

[Joe Subich, W4TV]

Apparently the KPA-500 includes the ability to operate in a CAT
pass through mode (like the P3) with Elecraft and Kenwood rigs
(see Menu items RS232 P, RS232 X, RADIO, and SER POLL).

*UNFORTUNATELY* the Kenwood configuration is not documented in the
KPA-500 Owners Manual (unlike the Icom "band voltage" and Yaesu BCD
control configurations).

It would greatly assist non-Elecraft owners if the KPA-500 Owners
Manual included explicit diagrams and configuration settings for
Icom, Yaesu and Kenwood (RS-232 CAT ONLY) transceivers along the
lines of Figure 4 on page 13 for the K3 using "KPAK3AUX Cable and
Separate Key Line".

Without documentation (including information showing if RTS/CTS is
passed through from the transceiver as expected by Kenwood rigs
or whether the KPA-500 provides a CTS "pull up" on the RS-232 (XCVR)
jack) from Elecraft or access to a KPA-500 for "hands on engineering"
it is not possible for third party suppliers to provide any support
for (Kenwood) configurations that include KPA-500/KAT500 .
