WALT...
Some text went missing. It is most important that you *CALIBRATE the unit
for the frequency range you are interested in. * ( Say: 14.000 to 14.350 or
just a little bit wider than that.) DO NOT MISS OUT ON THIS STEP. See the
countless YouTube videos showing how to do this.
Ideally.. measure as close to the antenna feed point as you can... assuming
you do not have a huge amount of cable between that feed point and the
transmitter (991A) If not possible just measure at the end of the coax
that will connect to the transmitter. Usually the differences are very
small, if the coax is decent.
