K3 Report

[Julius Fazekas n2wn]

Thanks for the thoughtful and interesting report Rob.
I understand the NB is not available yet either (as of
a couple days ago).

Still, if the radio performs that well without the
"bells and whistles", what more could one ask??? ;o)

I look forward to working it hard in the contests this
Fall... *fingers crossed* But wouldn't be heart broken
if I still had to use either of my K2s. They're still
primo performers IMHO.

Cheers,
Julius

There are two noise blankers in the K3, hardware and DSP.  A few field
testers are using the hardware NB, but all of us have been testing the DSP
NB.  The latter has been dramatically improved with a series of recent
firmware releases by Wayne and Lyle.  By itself, the DSP NB is currently
VERY effective on a range of different man-made noises.

Yes!

Hi Ed,

It was the hardware version that I read about on the
contest reflector. Guess not all of the BT's have
them.

I'll be interested in how well the combo works in Oak
Ridge, seems like there are more and more RF
generators in town every day. The contest QTH is
relatively quiet, although there was a pesky street
lamp that wiped out 160/80 (has been fixed!) The
electric fences in the area haven't presented any
issues so far...

The K2 NB has been effective for most of my noise
issues.

Cheers,
Julius

The noise blanker will be in full production at the same time as the
rest of the rig. The field testers haven't gotten theirs yet, but Eric
and I have been testing it for some time.

My gaff not Ed's Wayne...

Just icing on the cake!

Thanks for the update.

Wayne, of course, is talking about the analog (hardware) noise blanker.
  There is also a DSP noise blanker which we *do* have, and by itself it
has been as useful to me as the noise blanker in my K2 and better than
the one in my TS850s. It is also much less affected by other in-band
signals.

Add to this some special AGC functionality (an AGC loop within a loop
with a very short time constant called AGC2) for dealing with noise
spikes that might trigger AGC, and you are really looking at *three*
lines of defense against noise.

One more thing, which I am finding useful in my noisy location, is the
"transverter interface" accessory, which might really be called
"low-level receive/transmit RF interface". This provides a convenient
insertion point for an MFJ or other RF noise canceller, without the need
to worry about t/r switching.

Of all of the features of the K3, I think that the anti-noise
functionality will make the most difference in improving my DXing here
in my noisy location.

My HS0ZCW station noise also included BCI in a very bad way, altho no BC
xmtr is in sight.

The ICE BCI filter cleaned it ALL up.... wonderful.

Coming up on my 50th year as a continuously licensed ham (and my 64
birthday), I still did not i.d. that kind of noise and wasted lots of time
running around looking at electric poles, etc.  Locals tipped me off.  The
way to i.d. it is to turn the rf gain way down and listen for short blasts
of what I call over-modulation... tiny pieces of words spoken over the BC
radios.

The VRF in my Mark 5 helped a lot and lost only abt one S unit of
sensitivity.  73

Check out the youtube video of the K3 in Tokyo.
I don't speak Japanese but you don't have to to see the interest Tokyo
hams have in the Elecraft products.
