![]() "nothermark" wrote in message ... If you can find an old scanner that has a true descriminator output instead of the phase detector types, then it is easy. Hook a DC scope to that point and fine a transmitter that has 1 khz steps . Go up and down one 1 khz at a time and see where the trace goes. At each point will be the 1 khz steps. Hmmm, had not thought about that as I am also looking for a deal on a signal generator. Come to think of it a 1 KHz shift between the receiver and a transmitter will look like 1 Khz of deviation.... I have done that many years ago when I could not afford very good test equipment. I did have a frequency counter that was halfway decent and an inexpensive scope and multimeter. Had to learn how to do things to get by with. Took a lot of time to do simple things, but I learned a lot in the process. Yes, if you have a true discriminator and a DC coupled scope the shift of an unmodulated carrier will look like the deviation. |
