Scope Tuning Adapter
The MFJ-44 is designed to provide Mark and Space filtering for the MFJ1278B MultiMode Data Controller. The filtered output from the MFJ-44 is used to drive a regular test equipment oscilloscope or monitor scope. The result is an accurate elliptical cross-hair type tuning display for a more precise method of tuning in various amateur radio signals. Some of these signals include ASCII, RTTY and PACTOR to name just a few. By using a monitor scope as a tuning aid the user can tell whether the Mark and Space frequencies of the incoming signal are high or low. The user can also tell the frequency shift of the incoming signal.
