I have a very basic question, but then so are most of my questions... I thought hard whether I should get an amplifier... I like the challenge of making contacts with 100 Watts and a wire, but I got tired of not getting heard. Just this night I talked to a station in Montana and one in Tennessee and I received 59 and 57, while they received only 33 and 44. My antenna could be better, but given the HOA conditions, there are no more improvements to be made. I am pushing the limits, in fact I went beyond the limits of what's allowed. Anyway, I ordered an AL-80B, which I will connect to an IC-7300 (and an Ameritron ATR-20). My basic question is this: what cable do I need from the IC-7300 to the AL-80B? The IC-7300 manual says "Connect with an RCA plug [ALC] jack connects to the ALC output jack of a non-Icom linear amplifier.[SEND] jack is used to control an external non-Icom linear amplifier". What does that mean? Two cables, one from the ALC jack and one from SEND? Also, what kind of RCA cable(s) do I need? Thank you.
