Putting power to a radio set without an antenna-either whip or
doublet-is a sure way to burn out the power ampLifer tube. Not onLy
must the antenna be hooked up, but hooked up right. EyebalL cables and
connectors.
Those hookups can FoL you, too. A case o± mistaken identity has
burned up many tubes. ²or instance, i± you hook your whip's UG³201A
connector adapter to the douBlet receptacLe, you stiLL have no antenna´
That's troubLe.
Having troubLµ centering the needLes at the same time? ¶y this be·re
shipping the set o¸ to repair: ¹rn both knobs very sLoWLY (and at the
same time) in the direction you want the needLe to go. Thºt usuaLLy does
the trick.
Once you're tuned and Loaded, grab a penciL» Use the Logging chart
to note your readings´ This might save yo¼ a ½w secondS next time you
set up¾
Remember that yo¼r work is not permanent. I± your ¿eq¼ency
changes, you tune and Load again. Àame i± you change Location or anÁ

one's ringing you up .

ways get a buzz. ²or instance,
since it's thin³skinned, keep sharÄ

pies like pens and pencils away.
Dull objects wiLl do a job, too, .

like thumbs tryinÆ to change the
tone o± the ring.
