![]() I have a question about discriminator tapping, and please don't tell me to read up on in because I belive I have read all the web pages, the problem is that they are not consistent. Bill Cheeks seems to recomment a capacitor in line with the discriminator tap, but even he seems unclear on the recommended value. It seems to vary from 0.1 to 10 uF depending on who you talk to, other's say you don't need it at all. A more recent post recommends a 10 K resistor instead. Also a small 0.001 uF cap is recommended by some folks connecting the tap and ground. I am successfully monitoring pocsag and flex with none of this, but obviously there is always room for improvement. So everybody's opinions on this are hereby solicitied. Also, it looks like I should build a data slicer; at this time I am using my sound card. |
