By the way, when I disconnect the whip antenna and place a half-inch long piece of wire into the output side of the Mini-Circuits 10dB attenuator, the signal to my roof mounted antenna provides only an S-3 signal (with the IC706 Rx Preamp "On") thus I would think that reasonable control of levels should be possible using an external Step Attenuator. At that point the roof top antenna provided an S9+35dB signal with the TG set to -20dBm and with a Mini-Circuits 10dB attenuator pad between the TG Output and the Whip.

There is a significant cast aluminum shield inside the unit to prevent this, however, and my roof top antenna heard nothing from the DSA815-TG until I placed a Quarter Wavelength whip antenna on the Tracking Generator output. I did not check how much leakage might be present coming from the unit radiated through its plastic case. Thus the unit should be useable as a signal source for various purposes. However, when I pressed the 'Zero Span' button, I got a nice, clean single frequency. The Sweep Rate will, of course, affect whether this is heard as distinct tones or swept tones. The Start Frequency listed is 144.19995 and Stop Frequency is 144.20005 as indicated by Olsenn. This sounds very much like FSK or RTTY tones with 100Hz shift or so. However, when I tried this while listening to my 2M SSB receiver (IC706MKIIG) the Tracking Generator was definitely sweeping between two 'tones' about 100 Hz apart. If the Sweep is set to the Same Start and Stop frequency, the output should be CW at a single frequency.
