Hello group, I was trying to use the bfo tuning aid on HF Signal web site. The link takes you to the new HF web site bfo page but tuning aid doesn’t start or even show up. Is there a new link to bfo tuning aid??

Thanks in advance for any help,

John,
The tuning aid does not work with all browsers. The browser must be able to receive audio from your computer microphone. The graphic display will not show until mic audio is present. The graphic display is a simple audio spectrum analyzer. Several free analyzers can be downloaded for various computer? operating systems. You may have a suitable one on your computer already. The two lines on the BFO tuning aid mark 300 and 3000 cps. Most audio analyzers will have a way of marking the displayed frequency range.

Thanks for the quick reply Dave. I have used the tuning aid before on my PC and had no problems. I will look into using another audio analyzer like you suggested.?

?Thanks, Happy Holidays

Hi John,

I tried the tuning page and also found it to be broken.? The Javascript is there; it's just not working.? HFSignals will need to fix it.

In the meantime, I have used this free Windows-based software:


Here is another online analyzer for hearing tests that should work with any browser:
