Would an n-way conference over ham radio offer good enough latency (if all participants are within a couple km and the signal among everyone is good enough) to make band practice possible ?
- ShinyCyril 6y agoI'm not a ham, but wouldn't bandwidth be an issue? I was under the impression that channel widths in the amateur bands were pretty narrow (<10kHz). Though I don't know if that applies to all bands, or just HF.
- ShinyCyril 6y agoSeems this is just for voice channels — SSTV channels have a bandwidth of 6MHz for example.
- packet_nerd 6y agoThe amateur radio rules prohibit music (except a weirdly specific exception for NASA). Also, HF tends to be really noisy and low bandwidth, not sure it'd be very pleasant for music. Edit: And another problem that's probably even more important for this use case, most common ham radio equipment is simplex (only one person can transmit at a time). In the VHF/UHF range you might be able to engineer a high bandwidth duplex (or TDM) system, but then your range would be limited to a few miles.
- xuhu 6y agoBy duplex are you referring to having one frequency reserved for each participant's outgoing stream ?
- packet_nerd 6y agoYes
- mnw21cam 6y agoMost ham radio equipment is half-duplex, not simplex. Your average consumer hifi radio is simplex, because it can only receive, not send. Ham radio is half-duplex, because it can send and receive, but not at the same time.
