Low audio on new sbitx v3


 

Hello.

Got my new sbitx board hooked up and powered this week.

I am wondering about the audio. I have tried both hooking up a speaker and also a set of earphones but the audio is not that loud, actually can barely hear anything either way with the audio turned up all the way.

Using a regular speaker and a set of regular stereo earbuds.

Have looked at the drop down menu for the speaker output and that's at max.

Any ideas? Have looked in the online docs but can't find anything about what should be the norm for speaker.

James,

Increase IF gain if it is low.

Do you have the IF Gain turned up?

If you want to know more, check the . The speaker is 8 Ohm, the maximum output power can be 2.5W. Pay attention to the supply voltage, because there will be no sound from the speaker below 10V.
Volume depends on a good antenna and IF and Audio settings.

My board has a bad and resistor going to the AF Amp. I am not at home to check the details but see

You can check the voltage at the lm380 to see if this is it. Do you have lots of volume via the sbitx wen page?
