Fan Noise Super-imposed Upon My Receive Audio.
I am experiencing fan noise super-imposed upon my recieve audio. It is particularly annoying when you're trying to understand a transmission during weak signal conditions. Would adding a filter capacitor across the fan leads help??? If so, what value would you recommend. Barry L. Williams

Adding a filter capacitor will cause the fan to not be as loud but its not gonna stop it completely.and as you probably know the v 8000 fan does a lot of cooling because the v8000 is a potentially 75 watt radio and that is a lot of 2 meter power. Just always make sure that fan is running at all times something else u could try is using a stronger power supply. Sometimes you need a larger power supply than what the minimum is. For example I think the v 8000 calls for a 12 amp power supply if u are using it for a base station that is a minimum it will make a weak signal humming noise if its not gettng enough amps to push it it needs 15-16 constant amps to work well and that's a minimum if you're gonna spend money get one 18 or 20 amps that way the radio won't works itself to death
. Thanks Kevin
