K3 Northwest Workshop!!!

[David Pratt-2]

I'm afraid that Lyle's K3 workshop on November 22 will be just a tad too
far for me to travel from North-East England, UK ;-(

I do hope it goes well.

Is there are possibility of streaming video of the proceedings being
sent to the internet so that those of us too far away may benefit from
Lyle's experience?

Sorry, no.

It's going to be tricky enough accommodating the physical attendees!

Guys,

I'm experiencing a strange behavior on AM receive of strong
medium-wave broadcast stations. My K3 is equipped with the FM roofing
filter in the FL1 position. It uses this filter for AM receive.

Before the problem occurred, I had set VFO A to 1.008 kHz by direct
frequency entry. There's a strong (S-9+40 dB) broadcast station
there. At that moment the sound quality was  good. Then I moved the
VFO A dial a couple of kHz and then moved back. This led to the audio
becoming very distorted. I could only undo the distortion by
re-loading firmware. (I've noticed this problem with the 2.63
firmware, but I see it also with the 2.58 amd 2.45 versions...)

Some further investigation learned me that the amount that I can move
VFO A before the problem starts occurring depends on the settings of
the DSP filter:

(1) With LO=0.00, HI=3.00, FC=1.50 and BW=6.00, the problem occurs as
soon as move VFO A more then 2.0 kHz from the start frequency of 1.008 kHz.
(2) With LO=0.00, HI=2.95, FC=0.45 and BW=10.00, the problem occurs
as soon as move VFO A more then 0.90 kHz from the start frequency of 1.008 kHz.

Has anyone else experienced this? Any ideas as to the cause of it?

73,

Frank PA4N

P.S. Another strange thing, that may or may not be related and which
I don't understand: why isn't the DSP BW value displayed equal to HI
- LO ? Can anyone enlighten me?

Here is an update for those interested.

Please, if you wish to attend, it is important that you RSVP.  If you
just show up on the day, you may be disappointed :-(

We have a total of 18 people who have RSVPed for the presentations, plus
2 non-technical attendees, making 20.  There are also 3 maybes.

I can fit in 3 more people before I have to request the "maybes" to
commit or free up their tentative space.

The event will *not* be video-recorded, or streamed on the 'net.  There
is a possibility that the *presentations* may be audio-recorded.  This
is not yet decided.

Attendees are welcome to bring cameras to take still photos.  Some
attendees may object to having their photo taken, so if you attend and
want to take a photo that may include a recognizable image of someone,
please request that person's permission.  Similarly, if you do not want
your photo taken, it is up to you to make your objection known.

Looking forward to seeing you on the 22nd,

Lyle KK7P
