The frequency is divided down by 26 from a crystal oscillator Stefan. I am
only expecting local reports at present though.

Hi Roger,<br>
<br>
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! :-)<br>
<br>
Best 73, Stefan/DK7FC<br>
<br>
PS: 8 uW is a litte less for our distance but maybe 8 mW in 600 :-)<br>

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