Ok, this strikes me as a bit strange:   I had pretty much settled on the Yaesu SP-10 but thought I would chat with Gigaparts and confirm that the SP10 External speaker would interface with the  R75.   To my amazement, the chat guy told he he was "not certain this would work as it was only designed for Yaesu tranceivers".     I thought maybe someone here could confirm this is a match before I drop $149 .
Thanks again everyone

Don

Just a guess, but most transcievers and receivers in the last 40 years or so seem to have been made with a 8 ohm external speaker connector, and expect an 8 ohm speaker to be connected to that jack. Any 8 ohm speaker will do. As I said before, do not expect hi fidelity from a HAM external speaker.

Don,

Just noticed you have a Satellit 750.  It has a fairly decent speaker.  Have you considered using the 750 line-in?

No I hadn't but a great idea - going out to get the patch cord tomorrow.   And you're right ,  the 750 is one helluva good speaker for a mid-range economic SWL radio .     Thank you, Sir !
