Quote from: unbeldi on April 15, 2017, 09:39:19 PMOne method I have been wanting to try, but haven't yet, is to seal the transmitter into a small plastic bag, and then place it into an ultrasonic cleaner for a long treatment. The metal encapsulation may be too much of a mechanical shield, but perhaps the sound waves are still strong enough.

This small vial of supposedly transmitter carbon granules has been on eBay for 20 days now as a BIN, hasn't sold. But the price gives you an idea of those little particles are worth, in general...There is at least one topic somewhere on the forum about removing the caps, "fixing" the carbon and resealing it. Must be at least 5 years ago it was posted.

Quote from: TelePlay on April 15, 2017, 10:14:12 PMDon't think so. Ultrasonic cleaners work by sending sound waves through the liquid and when them come into contact with a surface, that is where the micro bubbles are created from the energy and their collapse is what jars the debris/dirt loose. If the bubbles are cavitating on the surface of the bag, no energy or vibration would make it to the capsule much less into the carbon. Actually, putting the transmitter directly in the liquid would clean the metal surface but do little for what's inside.
Quote from: unbeldi on April 15, 2017, 11:13:13 PMWell, what you are describing is the action of ultra-sonic cleaning.We don't want to clean, but simply provide vibration. Clearly the ultrasound penetrates for some distance, you can hear it at several feet distance. There is no reason the sound should not penetrate the sample. The question is whether it is sufficient or even effective in principle.

I can (barely) grab the small silver center contact cap with a pliers, and discovered that it won't unscrew, but it can turn (see teeth marks on it in the photo below). However, I can also hear what I assume to be carbon granules scraping along the inside of the crimped area when I do this. It sounds just like sand or grit grinding and scraping between two surfaces, and the only thing in there would be the granules.
