Re: increase frequency coverage

 

Hi John,

I see here that you are suggesting what is right for a normal designs but this one is opposite
12Mhz - VFO, so you need to make the VFO go lower for the range to go higher.

Confused the hell out of me in the beginning. Then I programmed my Racal Dana to do math
and subtract VFO - 11.9985 -> giving me a -7.xxxxx display. The reverse is not available
in the 1992 model. Now with the negative frequency I might have a QSO with aliens eh?

Cheers
Raj, vu2zap

If your C93 is set to minimum capacitance, and the high end of the frequency range is still not enough, then remove a turn or two from the inductor, L4.
If your capacitor C93 is set somewhere above the minimum, then decrease it to raise frequency high end, and increase it to lower it.
