Why is there no audio?

  • Question
  • Updated 10 months ago
This is probably a newbie problem since I have just unboxed and fired up my used (new to me) 6500.  After an hour or two playing with it I've discovered many of it's amazing features, but I'm stumped by NO AUDIO output to either speakers or headphones.  Using panadapter 1.  Slice is turned on.  Audio panel says unmuted and reasonable volume and balance.  However there is no sound on any band. 

Nothing I've read in the SmartSDR manual helps.  What dumb thing have I missed?

Are you playing on speakers connected to the radio or computer? If computer, check to see what your default speakers are. I bet they got changed when SmartSDR got installed.

Both speakers and headphones are connected direct to the 6500, not the computer.  Where is this speaker default setting?

In the upper right of the software are the master volume sloders for speaker and headphones. Makes sure they are not muted. Set them to about half way to start.

Next on the slice volume set it to 50and make sure the pan adjustment is in the middle.

If that doesn’t work I would auggest a reset of the radio to defaults. Turn off the radio and hold the ok button in while turning it on. Continue to hold ithe ok button as it does the countdown then the power led will go white. Release the button. This will reset the radio to defaults and then you can set it up the your liking.

  • Sliders top right have no effect on radio speaker or headphones.  
  • Turning "Remote" on gets hiss on computer speakers, but no intelligence.
  • Slice volume setting does adjust the computer speaker noise level.  Set around 50.  Pan in the middle.
Looks like a radio reset is next step. 
  
On travel a few days.  Engage again on Monday.
Thanks!

You can MUTE sound in several places. For example, you can mute in the same Slice or you can mute for ALL slices on the top right as David pointed out.
The radio requires POWERED speakers, like PC speakers, connected to the back. It doesn't have a built in speaker.
Remember that you can HOVER the mouse over REMOTE or other parts of SmartSDR and a contextual menu will pop up providing extra info. In the case of REMOTE it will tell you where the audio is being routed to in the PC.

Not getting audio at all in the Headphones if nothing is muted is indeed odd. Only other guess is the MODE is FM and Squelch is enabled......

Finally, a picture is worth a thousand words. Once you return on Monday see if you can take a Screen Shot of SmartSDR. Try to get everything on the screen.

You probably know how to do this, but just in case......



There is a tool in Windows called the "snipping tool" that makes taking screen shots a snap. 
You can also use the shortcut ALT+PrintScreen
If you use Snipping tool, just click on SAVE (*the floppy disk icon) and then drag and drop the image into the typing field in the reply to this thread.

This is what happens if AGC is set too low.  Set it to somewhere in middle of the range.

One last attempt to get audio before I shut down for travel still didn't work.  Some last observations:

  • The speaker system connected to the 6500 is powered and I do have a hiss that can be adjusted by the various volume settings.  However nothing provides intelligent audio.  
  • Going FM and adjusting squelch turns hiss on and off.
  • Where is squelch for other modes????
  • Screen shot follows:

Click on the SPEAKER icon in the slice to open those options.
And take another screenshot. Squelch is only available on FM

I do not see any signals in your screenshot. Make sure your antenna is plugged in the correct port in back. 

Try another band like 40. You should see activity.

Ant 1 connector is the one closest to the center of the radio on the 6500. I made the mistake early on of connecting to Ant 2.

Some success.  Now have poor audio now at near max volume settings.  Not as good as my 7300.  Perhaps all this is due to poor speaker quality from my new Amazon USB speakers. 

Two questions as I shut down until next week.
  1. Recommendations on good quality speakers?
  2. Where is Squelch hidden?  Only appears on FM.  
Thanks all!!

no squelch other than FM mode.

I have the Bose Companion 2 speakers connected to the radio. Work well and good RF shielding. I also have the Companion 3 speakers on the PC. 

If you have decent PC speakers you can click remote in the upper right and it will route receive audio to the PC. If you do use Remote until you get better speakers, just remember it will want to use the PC mic. You can change the mic input back to what you have set now.

Squelch only on FM.

My advice is the Yamaha NX50. https://www.amazon.com/Yamaha-NX-50-Premium-Computer-Speakers/dp/B00MMP7XEW/ref=sr_1_3?s=electronics...

I had the Bose Companion 2 Series II (the $250 ones, they are called Companion 20 now) and they failed and they are not serviceable.
The new Bose Companion 2 Series III are $99. I lot of guys here like the Bose speakers. They were great while they lasted.....

Both the Yamaha and Bose have something I really like, they can be powered from the Radio Shack 12v power supply, in case the wall wart is noisy; and they both accept 2 audio sources that can play at the same time. So I can have audio from the PC and audio from the Radio in the speakers at the same time.
I also like the volume knob in the front of the speakers. The Yamaha (at least in Europe) come in different colors, so it easier to match your desk color combination.

Steve,
  USB speakers can not be plugged into the radio, The 6500 only supports 1/4 TRS speaker connection... If you have them plugged into the PC, then Remote must be selected in SSDR and Windows must be configured so that they are the default playback device..

In addition to what these guys said there is no squelch in modes that Flex does not see its needed :)
