[Elecraft] K3 noise-blanker

[Bruce McLaughlin]

it is strange how different people can have different results from the same
radio.  I suspect it is in part due to different environmental conditions.
For what it may be worth, I found that my K-3 noise reduction system is more
effective on phone then my Orion II.  The Orion introduces very considerable
audio distortion when used on phone.  It is more usable on CW but still not
ideal.  I understand that was supposed to be corrected in a future firmware
update but, as you know, TenTec has not issued an update for the Orion for
approximately 1 year.  In contrast, I find that the K-3 noise reduction
system is very effective on phone and it introduces no discernible audio
distortion when in use.  I find that to be amazing.  For that matter,
neither does the K-3 noise blanker cause distortion but, its effectiveness
appears to be somewhat limited.  I wish it did a better job on wideband
noise.  It is quite effective on short burst noises such as ignition, etc.,
in other words the more traditional noise problems.  It may just be me, but
my Orion II noise blanker does not appear to do much of anything.  Once
again, I suspect that could be improved with a firmware update or two if
only TenTec would do it.

I have both and they are about the same. Sometimes one beats the other or
the reverse.  Orion is mostly better in NR for phone and K3 is mostly better
for CW.  If one listens only to the Elecrafters Lovers Club, one will get a
skewed view of rigs.... similar to the old debate from VW car owners who
loved their little bugs well beyond rationality and the facts.  I loved my
old Drakes like that, but now do not love any brand.  gl 73,
