[ICOM] IC-7410 With ARB-704 And AL-80B

[Thomas F. Giella W4HM]

I purchased an Ameritron AL-80B and the Ameritron ARB-704 buffer interface 
for my Icom IC-7410.

The question is can I use a regular RCA male RCA male cable between the
ARB 704 "Radio" jack and the RCA (#8 in the manual) SEND CONTROL JACK {SEND}
jack of the IC-7410 for keying?

Or do I have to use the 13 pin DIN jack and the AME-PNP-13D cable?

I'm thinking that I can just use a simple RCA male RCA male cable between
the interface and rig but it's been so long since I used and Ameritron
amplifier with and Icom rig that I can't remember for sure!

Any comments would be much appreciated.
