The tuner on my shop stereo fades in and out randomly,like the antenna is being moved(it's not).
Any ideas?
All the other functions are normal,for a '70s Sanyo tuner/amplifier.

vacuum out the dust and dirt , electronics cleaner on the knobs

Done.
It's slightly better, but not cured.
The variable capacitor that does the tuning bit is WIIIDE OPEN below the cooling grille.I smelled several of my old houses in the dust plume. YUK.
There's no crackle in the knobs,just the reception fade.
Maybe it's my aura,or a diet high in nuclear waste.

could be an atmospheric 'skip' if the signal is weak

put up an L shaped 30 ' bare copper wire antenna between plastic insulators, the horizontal part oriented to the xmiter
