Hi,
In an attempt to improve the performance of
Grab1 & Grab2 at http://myweb.tiscali.co.uk/wgtaylor/grabber2.html
I have replaced the RF pre-amp before the
Softrock Lite SDR which I use to receive the 500kHz signals.
The replacement is a broadband low noise
type (M0BMU design) & will hopefully provide a better SNR over the previous
tuneable one which required regular tweaking.
I have also split the band into two SpecLab
displays with Grab1 covering 499 to 504.4kHz & Grab2 covering 504.4 to
510kHz. I think this is a better approach than the original 500 to 510kHz.
The 503.7kHz beacon grabber remains the
same as before using the JRC NRD-345.
