K3 Birdies

John N1JM
I know this has been discussed quite a bit before but I'm a little disappointed in the amount of birdies within the ham bands. Seems like lately I have found more than earlier. I have 3 on 40 meters that are a least S5 that I don't think were there before and am sure they are generated within the radio. I know the firmware can be set to get around some of these. Maybe I need to go in and tighten down screws again. I suppose this is a characteristic of down conversion ham band only type radios to some degree. The off-shore manufactured upconverted style radios don't seem to have this problem. I've never had a birdie within the ham bands on a higher end general coverage upconversion style radio that I have ever owned and I have owned a few from I-K-Y.

Sorry for the comments but I just had to vent :-).

73,

John N1JM

Have you tried the K3 birdie elimination menu item? See the K3 f/w
release notes for info on using this. It works very well on stable
internal K3 birdies.

Also, please note that if you have the sub RX, the coax cable that
drives the first LO of the sub RX needs to be routed exactly as noted in
the manual along the RF PCB. If it is up in the air it will cause
additional birdies.

The cable mentioned below is the longest coax cable supplied with the
sub RX kit.
