For me, it is more than a perception. To demonstrate this to myself, I used

Just seeing if there might be any interest here in my K3/100, serial number
4076 purchased in late February, 2010. Has the following options:
P3 Panadapter
K144XV internal 2m
KXV3A IF module
KTCXO3-1 TCXO
KBPF3 General Coverage Module
Filters:
2.8k 8 pole
6K 8 pole
400 hz 8 pole
13k FM filter
Surfing the elecraft web site I chanced upon a new software load for the
K144XV
So I just upgraded my K144XV software to v1.2.
Well worth the effort, it does reduce the receive spurs as advertised

Olli,
The Key Out and the ACC connector Keyout-LP are developed from the same
internal signal, but the driving transistors are different for each.
The Key Out jack is driven by Q5 and Q3 on the RF Board, and you will
find your problem associated with one of those transistors. See the

Yes, mics and mic cables are wired in a variety of ways. Some have four

Ed,
I would suggest following the instructions in the K2 manual. There is a
page near the end of construction which indicates a very good time to
install the headers for the options.
For the list of options that you have, it would be beneficial to install

Found the answer on page 14 of the K2 reflector sight so I have got the
answer to my question.

Hi Don,
many thanks for your advice. Just opened up the K3, located Q3 and Q5 and
measured there directly. Everything as it should be, 13 V bias to the gates

measurements at the RCA jack from the PCB and everything fine.

I use a THP2.5. I bought the interface cable for the radio from a resource

your own, then reference both manuals and construct. I didn't need to work
on baud rates which really are unnecessary. The signal

Hi James,
you don't need to connect an outside pull-up (only if you want to measure

I suspect that the BFO for LSB is not correctly for your KSB2 OP1 filter.
First check to be certain the SSB FL1 is set to OP1. The BFO frequency
for LSB using the OP1 filter will be between 4913.48 and 4913.65
depending on your particular filter center, and the USB BFO will be in

The P3 uses the RS232 connector.

If you happen to have the PR6 ... or other ... six meter
preamp, be aware that it's power is supplied via the
ACC jack, and a control cable for the THP amp will
need to provide an additional wire for this.

How do you have the RTTY FL1 BFOs set? It sounds like you are
attempting to use the default settings for the RTTY filter set, and that
will not work well.
Enter CAL FIL (with the internal probe placed in TP2), and first set
RTTY FL1 to the OP1 filter.
Then go to SSB and observe the

Sometimes Tip/Ring/Sleeve plugs give a false detent and the plug was
not all the way in. Also if a conductor in a cord has broken inside
its insulation, you can get this behavior, including everything

John,
For the OP1 filter, drop the high frequency marker to 2600 Hz and center
between the 2 markers.
Remember that what is important is for the low frequency corner (-3 dB
point) of the passband be placed quite near 300 Hz. That is also
important for the more narrow SSB filters as well.
