speaker issue


 

I have this speaker?

currently hooked up, and it sounds good at low volume but once i crank it up to medium the voice starts to get all distorted and im forced to turn the volume down to copy whats being said.

did i pick a crappy speaker or should i be putting a resistor or capacitor or something in line to fix this?


 

Well... the quickest way to tell would be to try another speaker and see if the problem repeats. If it does, then your audio amp might have an issue. If it sounds "clean", then the speaker you bought has the problem. Just looking at the specs of the speaker quickly, it looks as if it should handle the full output of the bitx without a problem. I have not yet done an exhaustive test of my receiver, but with a similar speaker design as yours, I get a lot of bad sounding stuff at high volumes. I wonder if the audio amp is oscillating or something? I'll have to see when I get a chance.



 

you need to remove C113 - that will help your audio. ?


 

i dont have another speaker, i wired up the headphone jack though and put a headset on it and it sounds great at higher volume.?


 

I also wired up the jack for headphones & the audio is MUCH better at high volumes. Must be junky speakers..

I just wanted to thank Tim for this. I saw this a while back but just got my BitX last week. I was working on getting a headset wired in and my audio sounded over driven as well. Removing this capacitor got rid of a lot of squeal and gave me a great volume control.
