Re: [TenTec] Orion noise blanker

[jerome schatten <romers@shaw.ca>]

Carl:

Does the Orion's NB unblank the noise in the presence of a signal outside 
but near the passband of the rx (every NB I've had does this)?  i.e. When 
listening to a CW signal, say,  under pulse noise conditions, and there are 
no other sigs present on the band, the blanker is totally effective; but if 
another signal is present, in or close to the passband, the nearby sig 
modulates the noise when the NB is on?
Best,
