Chris,
Look in the K1 manual (download if you do not have a printed version)
for VFO calibration.
This requires you to spread or shrink the turns on L1. Check the number
of turns on L1 to be certain they are correct.

Measuring the inductance is not a good approach unless you have a way of
measuring it at a specific frequency. The toroid material’s effect on the
inductance of the finished coil varies with frequency, and most LC meters use a
frequency below the HF range.

Paul,
As far as measuring the inductances, the listed values are only average.
Count the toroid turns correctly and there will be no problem.

Paul,
Yes, correct the turns count on T1 and T2 if necessary.
The impedance matching is important for full power output.
You are not the first to miscount the turns on a toroid (adding an extra
turn). Remember that a single wire through the core is one turn and a
full wrap around the core is
Thanks all for the feedback.
T1 correction is now made and now off to make a cup of tea (there’s a Brit in
me somewhere).

Fair question as to why not.
I guess it boils down to tolerance in the design. As T1 and T2 are impedance
matches maybe my error isn’t going to push things out of tolerance.
That written, the consensus feed back is I have counted the turns wrong on T1
and it’s easy enough to reduce a tur
You count "passages through the hole" as turns in all cases with toroid
cores. A straight wire thru the donut is one turn. I can't answer your
question ["does it make a difference?"] because I don't have a K1, but I
did build a K2, and based on that, I think the answer is "Yes, it will

Why would you choose not correct a known error?
Correct it and rule it out as a possible culprit in the event you have a
problem with the radio. If you don't correct it, and end up having a
problem, you'll wonder

I have completed the RF board RX build portion and about to test it with the
filter board and front panel.
I realize I may have a discrepancy on turns for T1. I count a turn by tracing
the wire around the toroid and get 4 turns of green but the manual page 14
states I should count a turn each

Dave,
Refer to the K1FL4 instructions and re-tune the trimmers on the filter
board. They MUST be done in the proper band sequence - 30 meters before
40m, 15m before 20m. The PreMixer portion is usually the most critical
for power output.
