[1000mp] Noise Blankers and IMD

[Tom Rauch]

The real point is this....

If you work CW and listen to weak signals on crowded bands, if you 
hear someone who seems excessively wide or has spurs, or if you have 
gibberish phantom CW signals bleeping and blooping on various spots 
on crowded bands (especially during contests or near large DX 
pileups), remember to reach up and be sure you have the NB gain 
control on the MP turned down. On the 1000D, be sure you modify the 
noise blanker to remove forward bias when not using the blanker.

Without doing that the, QRM we hear at that particular moment might 
really not actually be there.

In my opinion it would be better to spend 25 cents and fix the 
problem, rather than having to quickly recognize internal IM and 
remembering to check the blanker gain knob, but at least everyone 
should be aware it can be a problem under the right conditions.73,
