Greetings,
We are in the process of building a fire station addition where our truck room will now be split between a big 4 bay truck room and the smaller, original, two bay truck room. The new radio room will house our base radio and other communications equipment. Our base radio is a Kenwood Mobile TK -7360 pared with a Astron RS-35A, connected to a DB224 with hardline. We are VHF (155...) This setup has served us well for many years and with the move from the old to new radio room we will be keeping the same components but replacing the hardline with new line, new connectors, etc, and the antenna will be moved to a new mounting area on our new addition.
It used to be that in the old radio room we could connect an external speaker out of the 3.5mm mono jack on the back of the TK-7360. This was then connected to: A loudspeaker right outside the radio room in the truck room, a smaller external speaker inside the radio room, and a speaker upstairs in the meeting room. This was done without the need for an amplifier and everything worked pretty good.
Now with the move we need to feed two truck rooms, the external speaker inside the radio room, and I would still like to feed the meeting room upstairs.
Do you think that this will require an amplifier? I have no idea what the radio will feed and I am not sure about matching impedance/ohms from the receiver to the speaker. I prefer simple and the least amount of moving parts (less possible failure)
Perhaps some of you have a better idea/method/etc. We do not need a PA/Intercom system but that also would not be a bad idea - however we are limited by a budget and my guys work best with simple.
Any ideas would be appreciated.
Thanks - NoCoFire
