Sound powered phones have been and are still in use today. on large ships, because they try not to rely on electricity to send and receive messages.
AuthorSubject: Need Help With A Pair Of Phones With Power And Sound Quality. Newb (read 1343 Times)
I bought a matching pair of rev American 333 Corp rberators are discounted for $ 10.
Looks like you’re not getting results. Any of you can point me in the right direction and I would really appreciate it.
If I understand how sound powered phones do their job even when not plugged in, they should have at least a side beep.
I have checked all the wires and switches for continuity and they are definitely ok.
Polished contacts where the microphone / speakers are, still no luck
I also tried to connect this multimeter to a microphone / speaker and discuss this in the tome and see if voltage can be generated, but no.
I used 2 new phones with new sound, basically our own transmitter, and another receiver can just be plugged in.
What station on a sound powered phone circuit acts as the monitor for all stations?
CONTROL POST The controlled person must act as a controller for all transmissions in the chain in order to apply the latest rules and regulations for true audio telephony.
A 3-thread system was up to date. an ordinary, related person who can transfer an end person and another end person. The third is talking to another leader. (it was also a clear signal block)
The most common ones, such as TA-1 (you can find a lot of information on Google TA-1 / TP), e.g. mer, here: http://radionerds.com/images/2/22/TM_11-5805-243 – 13. Merge PDF
is only 9 and 2 elements together, they should work alternately as sender and receiver.
Parallel 5 should also work, but the signal may be weaker.
PS A low voltage supply, for example on / off a 1.2 V simplified battery or … generates unnecessary clicks!

Thanks for your help, one of the phones is working.
But the transmitter and receiver inside the other handset are not working.
Do you now have information on how to fix this?
I did a little research here, but as a newbie I don’t know what I’m looking for.
Does a voice powered phone require batteries?
Sound-powered telephone systems use electromechanical transducers to exchange signals over a single set of wires without the use of resistors or external batteries. Audio telephone equipment operates at low voltage levels.
They don’t send, don’t take delivery, and don’t click when low voltage is applied like they did with this other phone.
Are moving parts blocked by dust or debris?
Maybe our electromagnet is broken, the magnet is permanent …
(Actually, this is just a lot of guesswork)
