Hi Symon,

No, the BNC is for test gear only - there is a 51 ohm in series with it, so connecting a speaker would load it down too much. That's quite deliberate - I don't particularly want to listen to test tones . I do have a powered speaker connected to the Y-out of my 'scope, should I really want to listen to an amp; otherwise I can connect a test speaker directly to the amp instead of the test box.

You could fit a pair of 4mm terminals to the box for connection to a speaker, but there's a risk of confusing them with the power input, and you'd have to be sure you've set the impedance switch to high-Z when using the speaker. Seems hardly worth it - you can listen to it when it's back in the radio once it's passed all the technical tests.

Cheers,

Mark
