Hello HAMS,
It is quite some time that I have been enjoying QSOs using Sound blaster card on the PC. It is just great. The best part is when we make a Phone contact we occupy about 3Khz bandwidth,  on CW we use up 2Khz , while on modes like PSK31 etc, within 2khz at least 8 to 10 stations can have a QSO without causing QRM. Bandwidth occupied is around 31Hz. Very Little power is required. No more yelling into the microphone or pumping Gallons !!

Listed please find links to various sound card operated S/w few of them I have tried out. In case you come accross any other S/W which is more interesting please let me know the site address and your comments on the same.
Hope to meet you on digital soon !!
 

1.Digipan: I have tried this out and is very good,  quite popular  http://www.members.home.com/hteller/digipan/

2. Hamscope: have tried this out, This is also very good. One thing I found missing is a window to store the QTH info of the other station.http://users.mesatop.com/~ghansen/  Supports YPLOG      Has both waterfall and spectrum displays that cover 2800 Hz      Monitors two channels   Supports PSK31 (BPSK & QPSK); MFSK16; RTTY; CW      Written by KD5HIO

3. Helleschreiber: Not tried out as yet    http://iz8bly.sysonline.it/  Internal log.    Supports PSK31 (BPSK & QPSK), Hellschreiber      Written by IZ8BLY

4. MMSSTV :  Very good I have used this. http://www.geocities.com/mmhamsoft/    Internal log,   Supports SSTV   Written by JE3HHT, who also wrote MMTTY
 

5. MMTTY :  Very good I have used this. http://www.geocities.com/mmhamsoft/   Internal log, supports name and qth pop on subsequent qso, has contest mode   Supports RTTY   Considered the best sound  card implementation of RTTY available as freeware,   both Hamscope and Zakanaka use the MMTTY engine for their RTTY modes   Written by JE3HHT


6. MixW : This is the best of all the S/w I have come accross so far. One needs to register. Demo version are down loadable.
