The K3QEP Operating Position: At left is the Johnson Desk Kilowatt, excited by the Johnson Ranger above it. The Collins 75A4 is the primary receiver while the Collins R-388 serves as an all-band auxiliary. The Johnson Kilowatt Matchbox at right interfaces to a loop antenna fed with balanced line. The setup is completed with a Heath SB-614 station monitor and a decidedly retro-looking D-104 microphone. Behind the D-104 is a Hammarlund SP-600 receiver. (Click here for larger photo |

The
Heavy Metal Dept. at K3QEP: Large grey box at right
is a Gates
BC-1G ex-broadcast rig used on 160 meters. Racks
contain
other Home-Brew Transmitters and Amplifiers as well as a National
NC-303 receiver, mod monitor and scope. Audio chain is a
Gates
'Producer' Console driving a Gates Limiting
Amplifier. |

The
Balanced-Line Tuner at K3QEP: Each coil is wound with 50 feet
of
quarter-inch copper tubing and the variable capacitor has a
1-inch plate spacing. Bob reports the inductors show no sign
of
heating and the capacitor does not arc-over when he drives his
full-size loop antenna on 160 meters with full legal-limit power
through this impedance-matching network. |
