Post the schematic of your audio amp from the detector diode to the speaker and we will show you where the noise comes from.
Why bother, he won't listen anyway

But this circuit is new.Why bother, he won't listen anyway![]()
My wife asked why am I listening to beeps and whistles?I played with the audio file.
I don't recall ever taking shots at you. I do feel however, that telling others that I do this, is a shot at me.but watch out, they will take shots at you in the process.
I've got a list of parts to buy that I will send to Futurlec.
Want to see it and make suggestions?

I do not recall making disparaging remarks to others about you. I do remember suggesting to you, that you should be more willing to open yourself to other thoughts and ideas when it comes to improving your radio. I am sorry to hear you think I take shots. Ok, I do take a shot of whiskey from time to time.
Actually I said you were one of the guys that knew their stuff.
Man, had a good time last night. Got me 3 CW QSOs. Haven't done that in a while.![]()
That does sound like fun. All I got last night was laid.
Ok, maybe that was a shot...
Ah hell, even that gets old after a while. Then you got to get back to the real ****....radio my man! That's the ticket![]()
Umm, well either I don't know how to listen to radio, or you don't know how to... well, this is a family show![]()
Oh, here come the shots.
Dude, I'm sorry it bothers you that I can sit hear listen to a couple of french dudes talking down around 7.100 MHz with no problem on the home brew.
It's just that way. Too late to do anything about it.

You speak French? Impressive...
7 Meg band. I figured a little higher would be much quieter for noise.
Your 80m recording sounds awful like ducks quacking beside a loud waterfall. The BFO sounds like its frequency changes with the incoming signal level.
My audio spectrum analyser is not calibrated but it shows the voices have no low frequencies and no high frequencies. The noise is wideband and continuous so I think it comes from your audio amplifier circuit.

It's one of the parts I'm ordering from Futurlec.
I used it in the receiver I made 30 years ago.
I was lucky to have a Collins 2.7khz mechanical filter at the time.
Audio was quite clear. Used a LM380 to drive a speaker but often listened with headphones.
