Tech 833,

My Imax 2000 has always been noisy, even tried different radios on it, same result.
Since the weather has changed here in PA, static
has got really bad. Is there anything i can do to
tame this static??????

RW,
Your not the only one with that noise.
Here in Louisiana everyone has it in there radio's. The noise started Saturday 11/27/04 and was in and out (mostly in)until when in got home
12/2/04. I thought it was my new Imax 2000 picking up a transformer but it went away.

I'm still going to raise the imax another 8 feet
to get the feed point to 36 feet and higher than the transformer.

It's not the Imax, it is just noise. Using a lower performance antenna will lower your noise, and also your performance!

Just for grins, use a portable receiver and see if the noise is local to you or your home. I once had an increased noise level that I did not know was coming from my own home. After utter frustration at losing so much SW capability, I decided to see if it was me. Sure enough... A UPS internal battery charger went noise city on me. I replaced the UPS and my noise is gone.

I had the same type of thing happen to me. It was a Friday night, time to go talk on the radio with the guys, and I had static 20-over in my receive. I thought maybe someone threw me an Easter egg. The next day I traced the noise down to the neighbors house where they had a tv antenna amplifier that the coax wasn't screwed in tight. Tightened it and the noise dissapeared.

wow viking, that was a lucky break to actually find the source of your noise. when i get a strange buzz in my rx, i turn the radio up and walk around the house unplugging things till the noise is gone. usually its some stupid wall wart mussing things up.

Dimmer switches can be bad. Fluorescent light fixtures can also make noise. Computer monitors, too.

10-4 on the computer monitor noise! while recording the latest demo with my band, the sound engineer was trying to trace down a source of noise that was present on the recording. since we were paying for the time, i went into the control room to try and help. first thing i did was shut off his brand new monitor and voila!
he was thankful but also had a few sour grapes in his mouth. this hobby rules!

In retrospect, it was kind of fun finding the source. I took a pro 520e and a straight piece of coat hanger (about 12" long) and stuck it in the antenna 'hole'. For power, I wired a 9-volt battery (the kind you test with your tounge) and taped it to the cover. In the mic socket I put in a mic plug and shorted the rec and gnd pins.

From here, I just walked around pointing the radio and adjusting the RF gain dial.

...hey, whatever works! :-)

The static i'm getting in my Imax 2000, must be coming from our dry winter weather./ It rained
for 3 days & all was quieter./ Tonight it was dry again, static is back bad again./All i can figure./

I unplugged everything in the house i could
think of, still had static./ I do have a factory
close by that causes buzzing on certain channels./
But, the static i'm getting seems to be coming
from the dry winter weather./

Ahha! When it gets dry you get static but when it is moist, the static goes away. Something has a bad ground! If it is not your house, it could be the power transformer on your nearest power pole or even your neighbors. A portable receiver will be your best friend on this one.
