Re: Ok, so what's available in Mode A


I was giving demos at the Fort Myers Hamfest on both Saturday and Sunday, 4
passes total.  We made a total of 45 contacts.  I was running 5 watts from an
FT50R, in semi-duplex, into an Arrow antenna.  What helps me "hear," and makes
all the difference int he world, is use of a low noise pre-amp before the
duplexer.  It really works then.  I can even off-point the antenna 15 - 20
degrees and still hear the bird.

One thing that was really odd:  At one point I accidentally pointed the
antenna at the ground, and the signals went to full quieting, and the audio
increased 50 percent!  There was a TV tower 1/8 mile away, and may well have
been an abandoned fuel tank or some other metal object beneath the "sweet
spot,"  but I've never experienced anything quite like that before.
