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.

 

73,
