Advice Requested: Sound Cards for PSK-31 and RTTY?
I'm interested in getting into HF PSK-31 and RTTY. And maybe I'll try
some of the other sound card based modes too. Comes the question of how I should configure the dedicated ham station Winbox. Is there anything to be gained by spending money on say some Creative Labs or Turtle Beach sound card or another or are the usual generic motherboard "sound cards" good enough . . ? Thanks, Brian w3rv |

Kelly: The quality of your sound card beyond a SoundBlaster 16 is wasted. The effort is better spent in a better quality audio interface between the radio and the PC. The transmit and receive audio MUST be transformer isolated for best results. I also like to keep D.C. off of the transformer windings by using a .1 uf series capacitor. Your PC is ground referenced to the A.C. main electrical system and your radio is ground referenced to something else. Use a lot of ferrite beads to keep the RF out of the audio and the use of transformer coupling cleans up the rest. Tom -- Public Keys: PGP KeyID = 0x5F22FDC1 GnuPG KeyID = 0x620836CF |

Thanks, Brian w3rv If the card or on-board system is "SoundBlaster Compatible," and made within the last 5 or 6 years, it should be OK. I have used PSK with many computers and cards and have never had one that didn't work because of the sound card. Put your money toward a good interface. It's hard to beat the RigBlaster line. I have never used one, but I have heard good reports about the the MFJ interfaces. Tom KD6EVM |
