Connection

Internal battery power supply: Can use 14500 lithium battery x 3pcs with our battery holder or purchase our 18650 lithium battery pack. Both need to use Special charger for lithium battery, and must do a mod with the power jack connector, please check youkits.com for details.

External Power supply: Any 9-14VDC voltage or batter pack can be connected to the transceiver. It has a built in polarity protection circuit.

Antenna: Any resonant antenna can be connected directly to the antenna (ANT) with a BNC connector. If a non-resonant antenna is used an antenna tuner will be necessary.

Headphone: A stereo headset can only be connected to the headphone port (phone), impedance 8-32ohm. Do not use a mono plug.

Key/Paddle: The HB-1B has an automatic function that determines what type of key is being used and is initiated on power up.
