Probably needs to breath putting out near 100 watts pep.
with the coax disconnected from the base of the antenna check for continuity from the antenna mount to the frame of the vehicle, no continuity not...
well you either believe me or not, your choice but typical fm radios used by emergency services and private two way users are 50 watts and have...
you are full of ####
all you need then is this and is biased in case you have the notion to start up with ssb, biasing is a small electrical charge applied to the base...
do the antenna check
disconnect the antenna from the back of the radio and see if the noise stops, if it does nothing you do to the alternator will make any difference...
if you look at the stage to the left you'll notice the difference in the size of the output transformer and there are a few other give aways so...
that is a 2x4 and should only require 1 watt or less carrier with no more than 25 watts pep drive
what I'm telling you is the antenna has no counterpoise or less than is optimal which makes the radio think the antenna is more narrow banded than...
it's called a circuit
my point is if his swr is 2 on either end of the band that no amount of tuning is going to change that, the radio does not see a happy...
the if and the power section of radios are separate so if the radio is properly grounded when the fuse blows the radio will be dead since the if...
what if the noise is coming through the antenna? grounding nor filters will "rectify" this issue. the rectifier in the alternator is most likely...
if it the same on both ends of the band which way is he gonna go, lengthen or shorten?
depends on how picky he is and my instructions should improve the swr readings and stop any tx lobes or stop rejections or reflection that the...
most likely a grounding/bonding issue, you can do a continuity test between the antenna mount and the frame of the vehicle and the radio mount and...
what about Nickybots?
