content: Hi everyoneI’m currently learning about electronic communication and would love to get your quick input.What type of electronic communication do you use most often (e.g., email, messaging apps, video calls, forums)?And why do you think it's the most effective for you whether for work, study, or staying in touch with people?Just a quick sentence or two would really help. Thanks in advance! 😊

content: Morse and Telex are pretty much dead but were serious improvements back in the timeCommunication between what and what? human to human? human to machine? machine to machine? Human to mass people?The good old phone call is effective as you have an immediate response (or you know the other person is not available).Chat like apps for information transmission of information not much bigger than a sentence.Email for formal and longer stuff and documents (yeah, still not using on-line storage to share things)I don't like video call's. My hair is not always in the right mood. I'm not always in a visually acceptable place to answer (virtual backgrounds have solved some of that).

content: Quote from: User280719 on July 21, 2025, 08:47:36 amWhen I read "Effective" and "Electronic Communication" I immediately get furious because we have recently been forced to replace our effective method of electronic communication with an extremely ineffective one.Our method (we use since 90s): If 100 people per day will present their card to the RFID reader it generates 200 frames (100 with card info and 100 acknowledges).New, forced method: Reader can only answer if asked by controller. So to avoid noticeable delays controller asks 10 times per second and gets answer "No card was read". This gives 2x10x60x60x24=1728000 frames a day. It is 8640 times less effective = consumes 8640 times more energy and it is forced in times when we all should think about using the planet's resources.Such a change is absolutely contrary to my nature, but since it was recently included in the standard, ordering parties include it as a requirement and it breaks our hearts, but we have no choice.

content: Quote from: Swake on July 21, 2025, 10:39:36 amActually, you're wrong. Morse telegraph is far from dead - it's still the simplest, most robust, and most effective communication method for long distances, especially under poor conditions. Why?1)Simplicity:Morse needs just a single on/off carrier - no complex modulation, no audio circuits. Any basic oscillator and key will work.2)Efficiency:CW Morse signals can be received at extremely low signal-to-noise ratios where voice or modern digital modes fail. It's literally one of the most power- and spectrum-efficient methods.3)Reliability:Morse cuts through noise, QRM, QRN, and weak propagation like nothing else. Skilled operators decode by ear what computers can't.4)Popularity:In the amateur radio world, CW remains one of the most widely used modes globally, precisely because no other mode offers comparable long-distance reliability with minimal equipment.However, there are drawbacks - you need to develop listening skills to decode Morse code by ear, as well as learn how to transmit it manually. This requires dedicated training time, making this method of communication not accessible to everyone. But, once you have mastered it, you will be able to exchange information even under conditions where computers can no longer reliably decode signals from the air.Additionally, CW signals are much easier and more cost-effective to amplify at higher power levels because they do not require highly linear amplification.

content: Heck, you can even use Morse code to communicate by banging on pipes in prison (if such pipes are accessible).Not sure how they tell their dits from their dahs, but the do somehow.

content: Quote from: Swake on July 21, 2025, 02:53:32 pmI have simplified my example to show the essence of the problem without going into details.We of course check if connection is valid, but not 10 times per second, and all our communication is encrypted (but it was done later - not since 90s).Access control standard EN60839-11-1 for system being build in grade 4 (highest - government, military,...) requires alerting when you lost contact for 2 minutes.It is logical (this is just additional security) - you need not to detect it very quickly because:- tamper should detect disassembling or tearing off the wall,- signals from tampers have to be send before attacker can violate communication.Our controller can work with up to 32 readers. Standard requires reader to answer no later than in 200ms (suggests answering faster but allows for 200ms).Now answer the question: Which system (with many readers) better meets the requirement to immediately send a tamper violation signal:- the one in which reader have to wait till controller asks it if have something to send,- our in which reader send such information waiting only to see bus idle - typical frame is 1ms - so 99% times waiting 0ms and 1% waiting up to 1ms (there is very small risk of frame collision in which case after not receiving acknowledge in say 50ms reader repeat its message).In my opinion, we are forced to replace something good with something of questionable quality.
