Yaesu FT-818ND HF/50/144/300MHz All Mode Transceiver
The Yaesu FT-818ND is a compact, battery-powered, all-mode radio for the HF, VHF, and UHF bands. Here are some key features:
- Power Output: 6W with an external DC power source.
- Frequency Stability: ±0.5 ppm with the built-in TCXO-9 oscillator.
- Battery Capacity: 9.6V/1900mAh with the supplied Ni-MH battery pack (SBR-32MH).
- Memory Channels: 208 memory channels across 10 memory groups.
- Band Coverage: Operates on 160-10m, HF, 6m, 2m, and 70 cm bands.
- Portability: Ultra-compact design with the ability to operate on internal batteries.
- Antenna Connectors: Two antenna connectors, a rear panel UHF female SO-239 and a front panel BNC female.
Yaesu FT-818ND designed for amateur radio operators who need a versatile radio that can be used at home, in the field, or for satellite communications.
