terminal. Tape the end of the wire,
¢ NEVER allow the 13.6 V DC cable end to touch any
other parts,
5) Disconnect all 4 pins on J2 as shown below.
6) Connect a red wire to a pin (J7-J22) where minimum
SWR reading is obtained.
1) Connect an SWR meter between an HF transceiver
and the AT-130E. 7) Connect pins on J2 to obtain a minimum SWR
reading.
2) Remove the top cover of the AT-130E.
8) Adjust C8 to obtain a minimum SWR reading.
3) Select 2182 kHz and AM (H3E) mode for the HF * To avoid damage to the HF transceiver, DO NOT transmit
