Portable Satellite Radio Setup

The ability to operate off-the-grid is a huge advantage when hunting satellites. Coupled with a portable antenna, this battery-operated radio setup can be easily carried to any remote DX location while requiring only very minimal prep time (5 minutes). Simply connect a satellite antenna, turn the radio on,  select the pre-programmed uplink and downlink frequencies, and you are ready to make contact!

The portable satellite radio setup consists of the following:

1. Kenwood TMV71A full-duplex VHF-UHF radio with microphone
2. 12V 8AH lead-acid battery pack with volt meter
3. Sony recorder
4. Headset
5. Other accessories (not shown) such as SWR meter, patch cable, compass, flashlight, notebook, pencil, etc.

Everything fits in a small waterproof camera bag, with room to spare for some accessories.

This setup has been used recently in a satellite demo at a local hamfest. Since only 5 watts of power is needed to access the FM satellites, this setup lasts for one week of use (about 50 satellite contacts) in a single charge, perfect for DX-peditions!
