To help make this discussion clearer, there is no problem about
referencing the original article [1]. The author, SM5BSZ, has published
it on his website for everyone to see, because this topic of wideband
noise from transmitters needs to be much more widely known.

The sad part of this is that there is a standard solution to all of
this, the same one that works for Skype and BitTorrent.
BitTorrent comes from an anti-authoritarian background and does its best
to defeat network security measures. I think Skype was originally

My KX3 never ceases to amaze me with the DX I'm able to work on SSB

Thanks for the clarification, and link, Ian. I was just being a bit careful
in case I stepped on anyones copyright.
Thanks also for the clarification about what was being measured and its
effects on other people using the band. However, as a mainly VHF/UHF user,
it does worry me that we go
Similar issue here for a while.
When I first built the KX3 it calibrated out using the KX3 utility
fine. Several months later (Summer 2013) I was at the bench and re-ran
the calibrations using a power supply and dummy load. Cal failed on 10m
with High Current. I upgraded firmware and

I can’t get it to change speeds, or get PF1 to work. I have tried WM, and I

it to load into the memory.

Sounds like you have the same failure I do. Take the cover off and look for

excessive current but was told that it might smoke smell bad and be hot to the

Question.
Does 45 versus 75 baud make any difference to the K3. Or does it just
affect K3 decode? Or ... ?

I have the proper OEM serial cable for my K2.
I would like to experiment with sending frequency commands to the K2
using Windows Hyperterminal.
I'm sure that by now there are perhaps tons of user notes on the steps
one takes to do this.
Does anyone have any notes they can point me too?
Thanks!!
Hello Marcel,
Have you had a mono plug inserted into the speaker jack?
Even if you are just using one speaker, you -must- use a stereo
plug for the speaker/speakers.
The sleeve of a mono plug will short the audio IC and may
cause it to fail

I was running in the rtty TEST today, or trying too!
Only running one cluster and have that filtered so not many spots coming

I ask the same question: Has anyone found a source for Yamaha CM500
replacement pads? The thin internal part that fits against the transducer
is very fragile and comes apart after a while. I assume by now someone out
there has replaced those pads.

I have a Radio Shack P/N 274-0374 1/8 Mono Jack to 1/8 Stereo Plug Adapter

still shorts the stereo output. Suppose I should test it and find out. I

Gary,
A stereo to mono adapter will usually not work. If you follow the
diagram for most of those adapters, the result will be the same as using
a mono plug - the ring will still be connected to the sleeve of the mono
plug.
The only real answer is to change the mono plug of your ICOM SP 20
Bruce,
You can request an RSA number by contacting supp...@elecraft.com.
Be aware that SPLIT is a per band setting. If you set SPLIT on for one
band and then change bands, you will find that SPLIT is not active on
the new band.

Hello Don and thanks for the info…that’s what I expected…a short from ring to

suggestion. Somewhere I read that Elecraft had installed some bleeder
resistors (or ?) to help delay the inevitable smoke from the audio amp.
Marcel,
You have probably blown the speaker amplifier chip, U1 on the DSP
Board. Many of us have had the same problem. Elecraft has not
been able to determine the cause of the failures, so they have
not provided a solution.
The part is inexpensive, but is very difficult to replace because
