Hi Ed, IIRC it's normal for the circuit check meter readings to behave "squirrelly" as you've described for the 3 output checks. I think this function is pretty much only to "crudely" show that you have (or don't have) each output.
As for your 100kHz & 1MHz dropping-out when you load your 5MHz output into 25 ohms, this might be a sign of a marginal condition of your output section - e.g., 5MHz signal dropping too low when loaded with 25 ohms? However in practical use I think various destination instrument's timebase inputs might require a bit more voltage than you'd have at best into 25 ohms anyway. So I'd probably not load the 105B into such a low impedance.
