External speakers are better, but a simple reflector makes a big difference:
I use a small cardboard box sitting just to the rear of the loudspeaker
aperture as a reflective surface.

Mike,
That is creative and very nice, but a pair of high efficiency
(unamplified) speakers
I'd be interested in an efficient forward facing speaker in a matching
cabinet, say, P3 size. Or just a matching cabinet; I guess many of us could
do the rest !

Agreed. It would have to be a selectable option because there are many reasons
not to use it. DXers would find it most useful.

The new AOR AR-7070, which should go into production this year, will
probably arouse interest among serious SWLs.
From the results of tests made on prototype #2, I understand that this
receiver covers the frequency range 10 kHz - 30 MHz without any gaps, and
good sensitivity across this range.
The proposed feature would not be too helpful for DXers (at least THIS DXer)
either! Lots

I'm replacing the PC monitor in my shack and it appears today's current

This has been recently discussed, but I would like to see the ability
to run external SDR sw with the K3. At present only the K3 firmware
can be run and, as far as I know, that sw is under Elecraft
proprietary control (and that may be a good thing right now).
The true promise of SDR is the
LED monitors are still LCDs. they just use LEDs for the backlight, instead
of fluorescent lamp. In general the LCD monitors are quieter than the CRT

are RFi-quieter that CCFLs. (cold cathode fluorescent) as a breed.

The simple SBL-1 mixer can already do that. I'm not sure how low in
freq. it would work, but 20-KHz seems reasonable. Just tune the K3
at F to F-480 with an LO = F-500 KHz
Using an LO = 3-MHz the 80m band could be translated (mixed) down to
0-500 KHz (with some limitations near the bottom
The K3 is actually a K3/100.

Hello Wise and Powerful Reflector;
I am experiencing a confounding problem with Ham Radio Deluxe, Digital Master
780 and my K3. I've determined that HRD polling the K3 is introducing a
croaking pulse-like noise into my signal chain. I know it is HRD because if I
quit out of HRD, no noise.

I strongly suspect that HRD is NOT causing this
There are also two pin 1 mods that solved my problems. Search the

Hi Jim;
Thanks for the reply. HRD must be the source of the signal. It disappears
mid croak when I quit HRD. That's not to say HRD is to *blame*.

Hi Joe;
Thank you for the reply. As I mentioned to Jim , the noise completely
disappears on RX when the antenna is disconnected. This leads me to suspect
that the RFI is coming in on the antenna cable. Does that sound right? If it
was coming in on the USB to serial I would expect to still
Eric,
Joe is correct.
The fact that the noise disappears when the antenna is disconnected AND
when you shut down HRD indicates that your serial cable and/or the USB
to serial adapter is radiating trash and that trash is being picked up
by your antenna.
Jim's suggestions are valid for that

It's NOT. The digital circuitry producing RFI is the SOURCE of the problem.

You've got plenty of answers about proper cables and application of ferrite
noise suppression, but one thing hasn't been mentioned: Are you using the

That's another symptom of Pin One problems in the equipment where both
cables are connected.
