[Boatanchors] Drake 2-NT & Knight V-44 VFO

[Rob Atkinson]

Not all vintage VFOs work with other rigs.  For example the HG10 has
low output compared to some.  The knight VFOs are given as 10 to 80
but in reality, they double from 160 to operate on 80--they just don't
have a bandswitch for 160 because they were supposed to be for 10 to
80 meter Knight Kit rigs.  I'd check the VFO specifications for the
V-44 or measure its RF voltage into the high Z load, usually a 6AG7
and look at what Drake requires for the 2NT.  It might be that the
V-44 doesn't have enough voltage for the 2NT input.  The WRL VFOs have
a lot of voltage.  The Hallicrafters HA-5 might be a good choice.  But
of course it would be better to get the one you have working right.
