To me, this looks very much like a "DIN Lautsprecherstecker": Positive is the small hole, negative the wide slot. Loudspeaker, if I ask google, is zvočnik in Slovenian – so the "ZV" label makes sense; you can switch between speaker pair 1 and 2.

Is there something that makes amateur radio speakers better or different than any other kind of unpowered speaker of equivalent wattage and impedance? Some may have audio filters, headphone jacks, or other such application-specific features. They could be somehow designed to be best at reproducing the frequencies important to intelligible speech, as ...

LEVI means LEFT DESNI means RIGHT ZV1 is speaker one ZV2 is speaker two S this radio has connections for two pairs of 4 ohm speakers. I guess LEFT ZV1 and RIGHT ZV1 are main speakers and ZV2 are additional (as option). Each speaker connector is DIN speaker connector with two contacts. Wide contact is speaker minus, circular contact is speaker plus pole. ...

When testing my speaker and volume knob(with music from my computer via audio cable), I the volume is too quiet. The line out on your computer is designed to drive the line in on some other equipment, not a speaker. The input impedance on a line input is typically around 10k ohms, and at maximum volume the voltage is around -10 dBV or 316 mV. This is simply ...

The FT-70DR uses the same microphones as the FT-60, including the SSM-17A that you seem to have missed. The plug looks to be a 3.5 mm TRRS. The FT-60 is a common HT that has been produced for years, and there should be lots of accessories for it. It's not clear if the FT-60 and FT-70DR use dynamic or electret (condenser) microphones, but most radios these ...

Going by the pictures (not much other information to go by), it seems the breakout cable has a standard headphone Jack and a smaller plug for the microphone. That seems a standard configuration. I would give your local (or less local) ham shop a call and just ask them. Or,honestly,i'd prefer to buy the two connectors and solder it myself. If you have no ...

Just about anything will radiate to some extent if you feed it with RF. It's actually more difficult to make devices not radiate. An antenna is just more efficient. So sure, you can get your headphones to radiate RF simply by connecting them to an RF amplifier. Unfortunately, this doesn't do anything useful. Put your head between two cell phones, WiFi radios,...

Pin 3 on the modular mic connector, which is AF OUT on some Icom models (e.g. the IC-706) is labeled as "HM-207 detection, grounds when HM-207 is connected" on the ID-5100. So it appears that the 5100 doesn't have audio out on the mic jack, and any Icom-supplied mic with a speaker in it is incompatible. Any third-party speaker mic for this radio (I don't ...

There are already two answers posted with good information but here is a little bit more information to help with your selection process. Impedance Matching the impedance of the speaker to the speaker impedance range specified for the audio amplifier (the transceiver in your case) is important in order to ensure a maximum power transfer from your radio to ...

Our choice of speakers are important. They can make the difference between either hearing the other station clearly or straining to hear and missing part of the conversation. But we don't need "special" speakers, that may be expensive and not even be very good. The sound from the small tinny-sounding speaker in the top cover of that IC-765 under the ...
