Scanner Birdies

[Dreamflight767]

Hello:

I found some birdies in my 436HP. What/how do you deal with those so they don't interfere while scanning?

Thanks.

Look up IFX (intermediate frequency exchange) in the scanner manual. If that doesn't make the signal go away, it's not a birdie, but an actual signal.

Func+7 is IF exchange and will switch one of the oscillators to another frequency.

Birdie is an interference from the oscillilators in the scanner, could also be from a switching power device for the display or something similar. If it affects your scanning and IFX doesn't help you just give that frequency a permanent lockout when you encounter it.

Birdies will be present at the same signal strength when you disconnect the antenna, which is another way to determine if it's actually a birdie or an external signal.

All very helpful. I actually guess I don't have any as I thought.
