My tivoli pal radio is about 4 years old. It has started making awful loud unbearable noises randomly. Sometimes it seems to settle and play fine, others it is intolerably loud. It especially happens on turning on. Can anyone help?

I emailed help@tivoliaudio.com about the problem. Their suggested remedy:
It is pretty common over time for dust to collect in and around analogue tuners. Dust can cause drifting, scratchy noises while tuning, and difficulty finding stations. Regularly exercising your tuner will help to keep it dust free.
To exercise your tuner you will want to turn the radio on and turn the volume all the way down. Turn the tuning knob to the far left and then to the far right. Continue to vigorously turn this knob back and forth for two to three minutes. This will loosen any dirt or dust that may be lodged in your tuner and will recoat it in grease.
Success! After several minutes of vigorous turning, our radio’s tuning problems went away. Fingers crossed it stays that way.

Tivoli uses a non standard tuner so do not use any sprays or cleaners on it as these can damage the part beyond repair. As Paul suggests, excercising the tuner is the best first step. Basically with the radio on or off and at no volume turn the knob/dial fully clockwise then counter clockwise a number of times. This will help scrap off oxidation which seems to be the issue with noisy tuning.
If you get noise/crackles when turning the volume knob then this part only can be sprayed with a cleaner such as Deoxit.
If noise problems only exist when you turn the selector switch then yes that could be a problem and may need to be repaired (cleaned) or replaced.

This sounds like the same problem we have. I don't think it is the tuner. I think the contacts in the connector switch are loose. We had the selector switch replaced once already and the second switch is also failing. When I took the radio for repair, someone else had a similar problem. So, I think the selector switch is poorly manufactured.

We were having interference issues with our Model One with strong stations on the lower end of the FM dial. I tried an external antenna and that made it worse. I read on another forum that someone with the exact same issue mistakenly fixed it by putting a simple 3-way antenna connector on the antenna connector and leaving it in internal antenna mode. This worked perfectly, and the radio has never worked better. I can’t explain it, but it’s a great $5 fix.

@zbartrout, Is a 3-way antenna connector the same as a 3-way splitter? I want to try the solution you posted.

Late to the party on this one, but I find this a real troubling problem, considering the MSRP of at Tivoli PAL. I have a PAL BT, picked up used several months ago, and it often has this 'crunchy' tuning problem.
Is this really the only fix, to swab the tuning dial back and forth several times, every few months?
And I'm quite suspect of the 'dust & dirt' getting into the tuning capacitor. Let's just note that that is inside a box, fairly well made, and probably inside a metal shield soldered to the PCB.
I've spent most of my working life doing electronics of one sort or another, mostly 2-way radio, but some factory work, and I was tearing apart radios from the 1940's while I was in 6th grade. I just don't buy it about the 'dust' issue for a Tivoli PAL.
My apologies for being overly blunt and harsh sounding.
