Contemplating 1mW WSPR Transmitter


I am wondering if it is worth the extra effort to put up a 1mW WSPR transmitter. Ideally I would put the transmitter at the antenna. The antenna would be a single band, one piece (no sections), quarter wave with at least 30 radials, mounted in the center of the garage roof. I am not familiar with the stand alone transmitters available so any suggestions would be appreciated. The transmitter would have to operate off of 12V.

Does anyone have experience with the results that may be obtained with such a setup? Is it reasonable to expect spots from 1000 km or more? I seem to be doing better than expected with 10 mW and a hap-hazard setup.

Any suggestions or comments would be appreciated.
