Hi Roger,

How stable is your frequency? How is it generated? For QRSS-3 it can be generated by a home made LC oscillator. If you have a stable TX (frequency and drift), we could do some tests in some weeks. I plan a QRSS-600 window for 137 kHz. But first i have to find my noise generator that currently decreases the performance of the grabber :-( In QRSS-600 it will be interesting what can be done in combination with QRPP. What we have is time! :-)

Best 73, Stefan/DK7FC

PS: 8 uW is a litte less for our distance but maybe 8 mW in 600 :-)

This evening= my QRPp beacon on 137.675kHz is running about 8uW ERP in QRSS3 from JO02dg (East Cambs). Any reports or screenshots from stations in the area would be much appreciated.

All being well, I should have my "in the air" TX loop erected in= the next week or so and more power, so I hope that soon someone else will hear me!
