Calibrating one 1 ppm TCXO against another 1 ppm TCXO calibrator (for
those with the optional extra K3 KTCXO3-1) would not be a good idea. In
any event the calibrator is going to drift with time and need
calibrating itself every year or so.
G4JNT published a 60 KHz off air frequency standard
K3 S/N 60 arrived here on Dec 29, 2007.
It is K3/10+KAT3+200Hz Xtal filter (assembled)
I suppose it is one of first K3s in JA ordered by EDC, agency in JA.
I have already ordered KRX3, KPA3 and 400Hz Xtal filter.
K3 works GREAT as expected for CW and digital mode. (I do not work
SSB at all !)
My
GB3RAL at 50.05MHz should be a good signal in Warfield. I do not know how
accurate it is, it is well beyond my ability to measure it here at home. The
reference it is driven from is locked to GPS with a long time constant and
should be close to one part in 10^10. However, the frequency is DDS
Thanks Trevor, but of course, I wanted something now, and not when I've
built it :(
And I have the 1ppm TCXO, so when firmware permits me to enter the offsets
from its calibration sheet, I'll be all set.
And Elecraft make the XG1 and XG2 kits too.

I was working a contest this weekend and at one point the audio in my

At full volume I could hear a slight trace of noise on the speaker. I
reset power, and the audio came back.
I guess I should have checked the external speaker
Hi Chris,
I have learned not to trust the K1's power indication during antenna tuning
with an external tuner. The reflected power seems to throw off the value
displayed on the K1. Try this... after you have tuned for best SWR go into
the power out menu and bump it up a 10th of a watt and
Hi Frank,
I solved the problem by using one spacer at both sides, put 4 short leads
from used glass diodes in the spacer, with the diffuser diode leads at the
other end. Press the spacer to the diffuser and solder with as little tin as
possible. Now you have 4 long leads. Mount the assembly, not

I need some advice on wiring my K2 to two transverters. I've got a newly

How are you measuring those voltages? In any case, it looks like the driver
is not working. You will have installed a nylon standoff on it, I would look
for a short around that area.

The link to the Prolific web site for updated drivers for the KUSB is in the

that describes the solutions that have been discovered.
If any one wants a look , i took a load of photos while building my K3 and

Let me ask this again.
Are you saying, that since the mixer signal is a multiple of the TCXO
freq that any errors in the TCXO will be magnified as the ref signal
goes higher in frequency. This will then magnify the difference in
audio note of (say) 10 MHz vs 20 MHz for the same TCXO setting. A
I have seen folks indicate it is necessary to set OP1 as FL1 when calibrating
the RTTY filters. Is this true or can you set it to any width as long as
the filter is calibrated so the signal is in the center of the bandpass?

Multiple isn't quite the right word, but every synthesized signal in

You do not have to enter the menu at all - just press the WPM+ and WPM-

Charlie,
When the RTTY filter set is selected, the transmission path is through
the KSB2 (OP1) filter, so yes, you will have to set RTTY FL1 to OP1 (or
OP2 -- OP4, all the same filter).
You are placing the filter passband for transmission, and not for
receive. FL2 through FL4 can be set to

I do believe you could do as you suggest and connect one transverter to

I cannot really give you a quick positive answer - the real answer is
