In fact, it absolutely amazed me when I was told that I had passed my Extra class examination. So, please, just laugh at my non-expertise, and try to help me out. Problem: I own a 7300 and wished to augment the transceiver with an external speaker. I found one I liked, and tried to hook it up, but the volume is really weak even with the radio wide open AF wise. I looked up the specs of the 7300 and found that it handles an 8 ohm speaker. Check...the one I bought is 8 ohms. The gizzy attached to the speaker looks like the pictures attached. (Note technical terminology) I wired it up using the connections shown in pic 2 as it was already soldered by the previous owner. Should I change the wires to different points to get this speaker to play with increased volume? Go ahead and laugh....I am laughing at myself! Any input is appreciated.
