[Yaesu] Icom SP-20 vs ?

[martyp]

Hello,

I have an Icom SP-20 that I have used with every rig I have owned ... 
practically.. When I plug in the SP-20 to my Mark 5, I have to turn the 
volume up a little bit more than usual. Perhaps there is an impedance 
difference between this speaker and the Yaesu version ? Does anyone know ? 
Also, I have to turn my Koss headphones up a little bit as well. Thanks for 
the response, 73, and g.b.


Kindest regards,
Marty, W3QK
