Mike,
DE-9 is the proper designation for what most call the DB-9 connector.
The proper "DB" designation is for the wide 25 pin size housing that was
used for printers on the PC and on commercial modems.
When the IBM PC first came out, they used 9 pin connectors for the
serial ports and many

I just acquired a P3, but was surprised to learn that I need a cable (CBLP3Y)
to enable the K3 VFO frequency to be displayed on the P3. I located in my
toy box a couple cables of same description as the CBLP3Y, that being they
are terminated on one end by a RJ45 connector and a DB9 Male on the

Mike,
Now that Bill and Don have filled you in on the DB9 versus a DE9 issue, I'll
try to address your question about the CBLP3Y.
One of your cables alone will not do the job.
The CBLP3Y has two DE9s, one female the other male, and a RJ45 connector.
The male DE9 plugs into the connector on the P3
Hi all,
First post after couple of years. Recently I’ve put my K3 back to my bench but
I noticed that speaker is mute. It wasn’t before and after search for the
issue, I found something regarding the protection of mono plugs connected at
back of the radio, is that the case?
I connected only a
I do not have the K2 top cover for either kit. It remains on my K2. If

When I switch to DATA mode, the receive bandwidth is only about 600 Hz even
though when I check with Data MD it shows the USB mode. I have the 2.8
filter selected and it shows on the display and using the K3 Utility
program. The audio also shows that there is only 600 Hz bandwidth. When I

Jim,
Yes, the filter width in DATA A mode defaults to a narrow bandwidth -
even though you have the 2.8kHz filter, it still defaults to a narrow
bandwidth like 400 or 600 Hz (I can't recall which).
That is an aid to those who choose to use the VFO dial to tune in a
single data mode station.
Why did you turn the mic bias off? Have you tried turning it on to see if
it gives you the sound you need?

Hello,
I recently decided to upgrade my K2 to 60m and ordered the K60XV.
After building and installing the module and all the mods, I could hear
signals on 60m, but very very weak. Using the XG3 showed a difference of
8 S-points compared to all other bands. I tried to isolate the problem.
I
Electret mics, and capacitor and carbon mics, neither of which are real
common in hamdom these days, require a bias voltage in the 5-8 V range.
A K3 will provide that bias if it's turned on in the MIC menus. Dynamic
mics do not require nor like bias. Without bias, an electret mic will
The Shire SM58 mic is a Dynamic mic and does not require bias (required only
for electret mics).

Thanks for the help--Bandwidth was showing full on the screen on the K3s,
but when I hit the XFIL a couple of times it cleared up even though I did
not change any filters. It stayed ok for a couple of hours of making
contacts, so I hope it is cured... 73 Jim W6US

Jim,
Why use XFIL at all? The filter selection will follow the DSP filter
bandwidth, switching in your filters as needed for the bandwidth
selected by the DSP Width filter.
I never have found a use for the XFIL button on my K3, I do it all with
the width control.

Mic bias is used only with electret microphones. Dynamic (moving coil)
microphones like the SM58 can be damaged by DC on the coil! The bias
will certainly *further reduce* the output from the already low output
of the dynamic mic.

The SM58 microphone does not need bias.

Gernot,
You either have a malfunctioning U1 or you have a bad relay at K1.
Since you were able to get K1 to operate and select 60 meters, I suspect
U1 is the problem. Request a replacement from Elecraft support.
