Andrew,
While those ranges will work, I usually like to see the lowest voltage a
bit higher than 1.6 volts.
Set the frequency that produces the highest voltage (4000 kHz) and
spread the turns of T5 a bit to increase the voltage at R30. I would
suggest that you try setting it to about 6.5 volts. Then go back and
see how much the voltage at 7000 Hz has increased.
73.

K2 #7303 is slowly coming together and I thought I would check with the list
the results of the VCO Alignment (Page 64).
With the core of inductor L30 wound right to the top, the lowest voltage
achieved is 6.1v and the ranges are as follows:
80m = 2.29 - 6.10
40m = 1.594 - 3.115
30m = 3.253 - 3.84
20m = 3.01 - 4.97
17m = 3.71 - 3.94
15m = 2.456 - 3.638
12m = 4.92 - 5.37
10m = 3.91 - 4.88
Is it okay to continue with these results? I've rechecked the component
placement and T5 winding.
