[Hammarlund] HQ-180_RF_GAIN

[George]

Thanks to everyone that offered suggestions for obtaining a 10K + 15K +
on-off switch pot combination for the RF gain control for the 180. I tried
all the suggestions, Mouser, Toco, Radio Shack Tubesandmore and others. None
of the places could help me soo:

I installed a 10K pot and isolated the RF tube cathode and IF's cathodes
with a diode in the RF tube's line. The single 10K pot controls both cathode
lines with the RF and IF being isolated with the diode in the RF tubes line.
I measured the voltage on the RF tube cathode voltage with this arrangement
and it is almost the same voltage set up this way.

Any further suggestions, or a usable scrap RF + IF + on-off switch would be
helpful but for now the 180 isn't stock!

Thanks to everyone for their efforts.
