A lil swr knowledge

way too many people think this is rocket science its not....

 

more wattage means the radio draws more amps.... period

 

you can run a 98v off 8 gauge right off the batteries...it's a 225 watt radio.... now why would you need 6 gauge on a 80 watt radio that's doing 60 watts ???

 

that radio does not pull a whole lot of amps. ..barefoot that's 4/sure

 

true dat theirs a wire gauge formula for wattage and amp draw ...meaning the maximum amperage draw....

 

Yes exactly what i ment..I got ahead of myself when typeing..

 

Well i thought it was a bit much for a barefoot radio till i just looked up something..
12 ga which is what im running now is good for 20 amps
6 ga is good for 55 amps...

HHHMMMM just found a watt to amp calculator and put in 80 watts @ 14.2 volts comes out to 5.6 amp draw..A 300 watt will draw 21.1 amps...

Wire length to amp draw..

 

another add on to swr...Grounding..Specifically rf grounding..

 

my radio draws about 24 amps on am. 35/40 on side band depending
