Re: Distorted audio signal on shortwave (rx!)

@Spence: well great Idea!
I will record a video and upload it to youtube. Then I share the link here...

It takes a couple of days since I am in vacation now.

@Andy, I speak about low frequencies (ca. 300 ... 800 Hz) and not low volume.
The effect can be shown by putting a sound generator at the input of the TDA and wobble the frequency then...

I'll be back after my holidays...

73, Tom

Can I please inject a suggestion.....?

Make a short video and post it on YouTube as private for those with a link so we can all see the issue.

? Failing that I will create a guest account on my FTP server and upload it there!

De Spence M0STO?

Sent while portable! please excuse typos.

When you say "at low audio frequencies", do you mean low frequencies, or low AF Gain on front panel?

I think there may be a translation problem.
