Interesting Question...

>From Tower Talk Reflector:
    Martin Pelt <n4uu73 at gmail.com>    To   towertalk at contesting.com       Today at 8:01 AM   I am putting a 80 meter 2 element inverted vee beam up. It will be at 120
feet with 39 foot boom.

I have 2 questions dealing with switching from phone to cw without lowering
elements and using jumpers.

I plan to use ladder line on driven element coming down to tuner to switch
from cw/ssb. Will this work or is there a better way ?

On the reflector I thought maybe cutting it for ssb the having inductor
with relay at the center to switch to CW. Is this the best way ? If so how
can I easily measure resonate frequency with inductor inserted at the
center ?
