QRP Computer

I have changed my current set up for WSPR (other than my Multimode on 10.140073 MHz) in order to reduce power consumption, noise and to utilise Solar Power as much as possible. This will of course help considerably with Portable operation.

The Radio in use is the Yaesu FT-897. The computer the Samsung NC10 Netbook.

Running from 12 Volts DC the Computer takes under 2 Amps, this will possibly reduce when the battery is fully charged. Currently TX'ing 1 Watt on 18MHz the total current consumed is around 5 Amps. Hmm 69 Watts to comunicate at 1 Watt levels, still a terrible waste.
