I have two Advance Research Pre-amps on order. Both a MSP144VDG-160 & MSP432VDG-160 which are going to be installed local in the shack. The reason being is that I have 2 switchable array's. One is my M2 2M/70cm satellite array and the other is my 2M/70cm LFA array. I generally only use one array or the other.
My coax runs are short and I want to keep the pre-amp inside out of the weather.
Here is my question. I can either feed 12V to each preamp and have a on-off switch to manually select the one I want, or I can feed power to them via coax that the 9100 supplies by turning on the 144 and 432 pre-amp On-Off selections in the 9100 menu. I would rather go with the 9100 supplying the pre-amp relay power instead manually supplying separate power.
Here is what I need to know, in single band operation I know that each pre-amp relay would activate when on a particular band either 144 or 432. But what happens in satellite mode? Are they both active at the same time? I'm concerned about relay activations. I keep hearing about sequencers, is this required?
Let me know.
