[ICOM] Another R-7000 question

[Frank A. Ellis]

Ron,

The "default" radio had no DC connector on the radio
side, just a blank rectangular cover plate. When you
installed the optional IC-CK70 DC Kit (originally made
for the IC-R70, hence the "70" in the part number), a
new connector plate was installed on the radio, in
lieu of the blanking plate. This option gave external
access to the internal 12 vdc supply output, and 12
vdc radio input. The supplied jumper plug was wired so
that the internal 12 vdc supply looped back inside the
radio. When using the external DC cable supplied with
the IC-CK70 Kit, one could remove the jumper plug,
connect the DC cable, and power the radio with an
external DC source. This was particularly handy for
"alphabet" agencies doing surveillance from a van, OR
hams using the receiver in a "mobile environment", you
decide. The mention of "no connector" in the
operator's manual is consistent with the stock version
R-7000.

Hope this helps.
