I'm building a kit for the LNR precision mountaintopper 3 band qrp radio. I'm having problems wiring a panel mounted volume knob and speaker to hear the cw output. I'm new to home brew electronics and wanted some advice. My questions are as follows:
When testing my speaker and volume knob(with music from my computer via audio cable), I the volume is too quiet. The potentiometer seems to only give me audio at the far end of its range, and still it's very quiet. What could be causing this? Wrong pot? Wrong speaker? How do I match a speaker and pot so they work well together and give good volume control?
The radio has a spec that says "headphone output 16ohm min". How do I know what speaker and pot combination would get the best result with this specification for good volume control?
I've got 3 ring audio cable that I'm wiring to my small speaker. Do the left and right rings of the cable get wired to the 2 prongs on the speaker?
Please excuse my ignorance, I'm just trying to figure things out. Thanks for any help you can provide!
