Yes I know that Don, the purpose of the test was to see how much overshoot we
got with an CESSB processed audio verses with normal audio and compare them. As
part of my experiments I needed to see how much influence the audio drive level
had and tried different audio drive levels from 0 to 5
I'm always fascinated by those which use of a 4:1 balun when 450 ohm
line is used. In most all cases, the 450 ohm line is operated at a
known high SWR. The nature of 450 ohm line {or other line such as 300
ohm or 600 ohm, etc.} is that it exhibits much lower loss when operated
at a high SWR
Is anybody using the P3 TX MON to monitor modulation waveform with AM
transmission? I'd appreciate comments on how effective a tool it is.
I've only seen one video on youtube of a cw xmsn, and it appeared that the
P3 captured a transmit waveform and displayed it (like a storage
oscilloscope).
Has anyone remotely mounted an Elecraft KAT500 in a weatherproof enclosure?
My current antenna situation is an MFJ-994BRT fed with 100 feet of 9914F and
then either a 30’ length of 9913F or 450 ohm ladder line to any variety of 60
foot dipole antennas. I would like to replace the tuner with a
Generally good info snipped:
Actually at *any* length, other than multiples of one-half wavelength, there is
always some impedance transformation in a mismatched line.

Your antenna has a very low feedpoint impedance on 40 meters. The 30
feet of open wire line plus the 3 feet of 450 ohm is close to a quarter
wavelength on 40 meters. That feedline length should transform the low
impedance of the dipole to a higher impedance, so the choice of a 4:1
There was a discussion a while back on the Flex forum about their
implementation of CESSB in the 6000 series:

OpenHPSDR also implemented CESSB, about a year ago.

That would be a very interesting development, Wayne.

I'm interested too. I will be running K3/KPA500 to a flag pole antenna,
hopefully with the KAT500 at the base. I will likely power it with a
separate cable that will have room for control lines too. In the
meantime, I am back on the air, remote to W7RN.

Hello again,
BTW don't use 9913 cable. It is susceptible to water ingression causing
higher loss. All the coax at my site is from Times Microwave. The
substitution for 9913 would be LMR400. There are several variations of this
cable depending on use.

Hi Michael.
You bet. See
Thanks Knut. The cable is actually Belden 9913F which is filled much the same
as LMR-400 but has a stranded center conductor. I will search for your
articles with earnest, It appears from the photos that you only have the PC
port connected which should be easy to accomplish.

Hello,
I am a new owner of a KX3. I have been trying to figure out how to
interface the KX3 to my computer and get HDSDR to play correctly. I see a
lot of references to Omni-Rig. Why is that needed and what is its purpose?
I would appreciate any help I could get from someone running HDSDR

Paul,
Set the K3 LINE OUT level at 10, and after that the entire solution is
in the levels for your computer soundcard.
Sorry, but I cannot predict the settings for your particular
computer/soundcard combination. All I can say is that Fldigi works FB
in most instances.
Yes, Fldigi can
I use FLDIGI with my K3S with excellent results. I can provide screen

I would second the request to look into this if it truly improved SSB
performance as noted in the articles.
