Hi Steve,

 

I actually have a 746 Pro and also noticed the noise blanker's
ineffectiveness.

 

I used my K-3 for a month without getting around to trying the noise
blanker.  Then one day on 75 meters in the morning, I was in a group and had
S8 noise; the kind of noise that sounds like ignition noise, except I was in
the shack and no cars were running.  I turned on the noise blanker, tweaked
the settings, and was able to drop the noise down ~ 2 S units, so that I
could hear the group.  Since then I've been very impressed with the noise
blanker, but, I notice that it doesn't remove all noise.  I also have a Mark
V FT1000 MP and it's noise blanker also doesn't do much.  In my opinion, the
K-3 noise blanker is definitely a plus in the radio.

 

I also have recently played with the receive equalizer, reduced the higher
frequencies ~ 6 dB, and hear less audio noise.  I've gotten used to doing
this using EZ_K3 which allows me to save the equalizer settings for each
mike, and my speakers / headphone.

 

Good Luck and 73

All -

 

One of the reasons for purchasing a K3 over, say, an Icom IC-756ProIII was

that the ProII I used to have had a noise blanker button, but it never

seemed to actually do much.

 

Sadly, I'm in the midst of several severe power line noise sources (the

power company is getting to them as they can), but I'm finding that my K3 NB

is having no effect, in ANY of the zillion settings available.  This isn't

strange, bizarro noise - just arching from a power line.   Is anyone else

experiencing less than satisfactory NB performance with their K3?  I'm

running the latest Production firmware.

 

Comments appreciated - you can make them private, if you like, and I'll post

a summary.

 

Thanks,

NOTHING removes ALL noise.  The K3 can pretty much nail key clicks.  It also
completely kills whatever my neighbor beyond my neighbor does in cold
weather that I can see all the way up to VHF analog TV.  I'll take those two
and smile about anything else only moderately reduced.

I note at one point some had complained they couldn't eliminate some of the
(Chinese?) jamming signals.  I would note that those signals were
specifically DESIGNED to resist elimination.

73, Guy.
