“Real hams don’t read manuals!”
Ok, but at least read this one section before you transmit:
Safety Warning: Never operate your AT-1000 with the cover removed; lethal RF voltages may be present
during operation. Never exceed specifications.
1. Connect your AT-1000 to a source of 11 – 15-volt DC power capable of supplying at least 1 Amp, red
lead positive; the pilot will flash once. Press the Power button to turn on the tuner.
2. Connect your amplifier output to the AT-1000 input socket labeled “Transmitter” using 50-ohm
coaxial cables. Connect the coax lead to your antenna to the AT-1000 output socket labeled
“Antenna”.
3. Set your amplifier to “Standby” mode so it will NOT operate when you transmit.
4. Transmit a carrier from your exciter of 20 watts CW, FM or AM.
5. Momentarily press the “Tune” button on your AT-1000. An automatic tuning cycle will begin, then
stop. Check the meter to ensure an SWR of 2 or less before using your amplifier.
6. Tune your amplifier if needed; you’re ready to transmit.
