Ooops one other comment. You really can't see anything since its a random and spread signal. It all looks like noise. I ran into this when I was home brewing a 2201 converter for the missing antenna that seems to always be the case. After the prn comes off you can see a signal that lets you adjust things or tell how good or bad a signal is. Most of the modern rcvrs will not allow you to get to that point. Its all in a chip. Examples of units that do alloew you to dig in the austron 2201 and Odetics. Regards Paul WB8TSL
