Unsuccessful QRSS Online

The other day I turned off my WSPR, Home QRSS Grabber and DigiPan receive programs, and installed my small QRSS Centre Dipole Transmitter.  The System ran for about 30 hours, But Grabber spots were not reported, not even my own remote grabber which is about 8 miles away.

I do not think the 43uw (as measure on an RF Test Set) into a dipole at 15 feet AGL is enough for DX and the ground wave can not go the distance to my grabber.


Centre Dipole Insulator QRSS Transmitter


The Transmitter is installed via clip leads into the Centre Insulator on a 30 meter Dipole.


The Transmitter's Working QTH

Planned improvements include more power (qrp QRO), maybe up to a few milli-watts. I have some 2n7002 which will work great for a PA, at the expense of battery life. Just another project to finish - Don't ya' just love it!

  1. Perhaps you could power it from a solar cell, then it would run forever as long as the sun is shining!

  2. A solar cell for power has always been my goal, but only if it looks like it will receive conformation via Grabber that it works at this low power.
