Hi Art

Variometers can be very lossy variable inductors. For proper

up that is similar to mine except I split the coilnumbers by two and
it is still to insensitive so now I have to put a blob of solder in
betwwee the coils to short them until I get the right ratio to suit
the antenna. I like to slow down the swr meter so that I constantly do
not scoot pass the right point
