Topband: RX antenna switching

[mike l dol dormann]

as what you would expect from an operator that uses an NC183 as his main
station receiver, i have a piece of Plexiglass with five sets of ordinary
wall switches mounted on it in a row; each pair switches the hot lead and
the shield of the antenna in question. mistakes are common, but you  get
used to switching two to off and two to on when you change receiving
antennas. the switch output goes to a single 6SN7 cascade
preamp............
