AI Thread Summary
Finding the frequency of a radio without using its tuner is challenging, especially if the radio does not display the frequency. The discussion raises the possibility that the unknown frequency might be outside the range of standard tuners, making it difficult to identify with other devices. Users speculate that the radio's tuning mechanism could be unique or specialized, contributing to the difficulty in determining the frequency. The lack of display further complicates the process, leaving users unsure of how to proceed. Overall, identifying an unknown frequency without direct access to the radio's tuning capabilities remains a complex issue.

If you have a radio and it is tuned to a specific freq, is it possible to find out what that freq is without touching the radio? I have this radio that has a button that tunes to an unknown freq when press. I can't seem to tune to the unknow freq. with other radio. is it special or something? Maybe it is beyond the range of traditional radio tuner range.

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
