The code that I put on on CGRAN yesterday:Wow, sounds good, I've got a bunch of 50KW stations about 2 miles away and I cannot get any to sound good at all. What receiver code are you using? https://www.cgran.org/svn/projects/simple_fm_rcv And the supporting RDS code: https://www.cgran.org/svn/projects/radio_data_system I'm using a TVRX2 on a B100, and this was with 8-bit baseband samples at 320Ksps input rate to the FM demod. Your problem might actually be that you have a *bunch* of 50KW stations close by. Although with 70+ dB of dynamic range even at 12-bit ADC sampling, with the gain set right, you shouldn't have too many problems. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org |
