Have you tried wrapping the monitor cable with foil.  Not all video cables are created equal.  If this does not help try wrapping the monitor making sure to slit the or punch the foil for all of the vent/cooling holes in the case.  A pencil will work well for opening up the vents.

> I am receiving interference from my computer monitor mainly in the 20 meter band that almost obliterates the PSK-31/RTTY section of the band. I have tried the available chokes from Radio Shack with no improvement. This interference also effects 15meters slightly. No problems with 40 or 80 meters.
> Monitor is about 4 feet away from the radio/tuner setup with cables for each seperated as well as possible. Monitor is almost brand new CRT type. I have returned to point of purchase for exchange which they did but the problem persists.
> Any suggestions would be very helpful. . .

> PS: I did wrap all of my exposed coax with alluminum foil which dropped the interference a little bit but not much. Also checked all of the PL-259 solder joints and they are good.
