    It all depends on the Microphone you use and what you have your Mic Gain and other levels set at. I can tell you that a ASTATIC D104 or SADELTA microphone will be quite a bit more touchy than others so if the recieve folks are not hearing it on your transmit thats great you cant ask for anything more. As far as the noise you hear you will get used to itsome fans are louder than others and some just plain annoying. Where did you get that kit you are running?? I am having a RCI2990 redone and might as well do that to as an option if need be.

    Older thread put maybe someone else can use this info

    I recently got a pretty good deal on a 2995DX and am now using it as my main base.

    Oh I definitely thought the internal power supply fan was too loud. Friggin' hurricane strength. Unbelievable - ridiculous - crazy ass too loud. Like somebody is operating some KW tube amp with a giant cooling fan right next to the mic. Totally unacceptable.

    So I went inside. Not much trouble to get the top off the power supply. Confirmed the fan is a 12 volt type. Tied into the + lead (you can pick either) and added a panel mount 100 ohm potentiometer which I installed on the left rear corner of the rig. This slows the fan down to any setting I choose, slowed the fan down to a tolerable noise level (with the cover back on) and fan still moves plenty enough air to do the cooling job. Now no one can hear the fan through the mic which is a sensitive D104.

    Do with any 12VDC fan for any device cooling job you have. Add a 100 ohm pot

    For AC fans, go to hardware store ect... and get a Ceiling Fan Speed Controller and install per instructions on package. AC pots like this are also called rheostats.

    Good luck ! - Loving the 2995DX Also replaced the yellowish incandescent meter lights with while LEDS. Really brightened the meters up.
