Hello LF,
A small update on my LF Grabber status.
A new active probe antenna was installed today which I hope will
provide improved S/N and maybe also lower the level of the strong sporadic QRM
you've all noticed. I have added a new LF page at
http://www.qsl.net/4x1rf/lf/lfgrabber1.htm
with QRSS-3 and QRSS-10 windows centered on 137.700kHz, page refreshes every
minute. I'm not sure if this is the most used frequency for fast QRSS so
opinions wanted. I hope that this new page will be useful to those operating
faster modes.
I do have again to apologise for the QRM you all see
sometimes on my LF Grabber, it's not under my control and looks like I/we just
have to live with it for now.
Future plans are to use a dedicated
137kHZ receiver (most probably a modified for LF SoftRock) and to put the
HPSDR transceiver back in service for WSPR.
Thanks to all the
grabber visitors, I hope you've found it useful. This more than justifies the
effort on my side.
Also thanks to Stefan DK7FC and Markus DF6NM for
suggestions and assistance.
Wish you all Happy Holidays and a very
Happy New Year!
