Re: [softrock40] SoftRock SDR and LF
Jim Moritz M0BMU has published a LF lite in the RSGB book LF Today.
He uses a 4 MHz crystal for 500kHz and 1 MHz crystal for 136 kHz some
component in the osc. circuit have been changed for LF. M0BMU has
modified the input filter which is different to Tony's version as used
for IF applications.
I'm planning to modify an old 14 MHz lite using a SI570 instead of a
crystal see http://www.sdr-kits.net/.
If only I had time to get on with it now!!!
