The 'char/min' is an abbreviation for 'characters/minute' or 'characters per minute'. So 93 char/min would mean 93 characters per minute...as in sending or receiving speed, depending on what you're using the decoder for.

I was a USN radioman. Good to copy Cw up at least 25 wpm. Used to love doing contests, rag chew all that. Then I ended up with essential tremor, which put me off the air on CW for decades. Piero Begali helped me get past that. Discovered that everyone had gone to computer generated CW over 40 wpm. Just now getting back on the air & got one of these to help my jaded ears copy these machine code show offs. Ain’t a bad device but I had to modify the resistors around the tone control to match what my ancient ears now tolerate. Still not a bad deal. We’ll see how it works in the next CW contest.

Excellent job on analyzing and presenting the details. Especially when you got the kit with no accompanying instructions. The device happens to be not very good at decoding, highly dependent on good signal quality and perfect keying. That is true also of many of the much more expensive decoders too. Most keyers of today send perfectly. But receiving Morse more reliably awaits advancements in AI. Thanks for the video. 73 from KD2KWH.

Same experience here with the one I got. Takes a strong signal in order to decode. When the signal fades (though still copyable) the little Chicom decoder can't handle it. I've got an ancient (and huge) Microcraft Code Star decoder which doesn't miss a character; if the ear can decode it; so can the Code Star. But, that thing cost big bucks back in the day.
@hamiltonstewart87395 жыл бұрын
Decoders are very tone sensistive. If it is set for 670Hz and the radio tuning makes the tone 700 Hz you will get garbage. As shown backing off on the signal does help but tone is important. The largest problem with decoders is simply the no spaces, all dits, bad code on the air. Decoders are a good check for your sending, especially for spacing. If you send a A N and decode a P you have work to do. Some OM are very animated that decoders and other gagets are BAD. While I will agree they may be a distraction and add time to properly learn CW anything that gets someone to listen to CW is good. Given enough time they will learn code inspite of the toys. TMI - Most decoders use a PLL to detect the CW, the loop bandwidth can be very narrow, the tone must be close.

Although it has its short comings why not do some experimenting by making different filters to improve the incoming signal. if the radio is picking up a lot of noise , ' As HF does" why not compare try it on an SDR qrp radio or similar where the back ground noise has been improved by the use of digital filters . And for the cost of few dollars what do you expect, isn't ham radio about experimenting and trying different things or has that time now come and gone overtime with our expectations. We are now spoilt with new radios and equipment as new items flood the market of choice as new improved technology moves forward . Our forefathers that used ham and those who had no choice to use what they were given or build what had to work with , what would they think now if they seen what we have to day ?. It will be the same with the next generation in another 20 years as they look back , and the next after that one and so on. I like seeing reviews and I think t is great people go out there away to show others but at the same time, there are a lot of wingers over a few dollars..... instead of taking a problem and looking in way of improving it as a project, Ah its from China its crap ill just through it i the bin , where is most of your equipment made today? back to basics is always a good refresher to see how far we have come.

If you want a decoder/reader that works look for an old ERA Microreader. They work for CW RTTY. The ERA has built in tutor for sending with a key or auto for receive practice as well. The later ones could also decode Navtex. ** Navtex needs Mk4 Firmware revision. ** All the modes work well when connected to receiver audio output. **

I had no luck getting mine to function. I plugged a stereo aux cable out of my MFJ oscillator, into the right side. Then plugged a small speaker into the left side to monitor. I could hear the tones going through... No matter how I dialed the oscillator tone, and dialed the pot on the decoder device I never got the light to light up. I tried doing the contiuous tone at various settings on the oscillator, and slowly turning the pot through its entire range, and the light never lit up.

Personally, I'd be worried to use this with a practice oscillator. I think it may discourage more than assist. I'd prefer being told that my code looked right but my timings were loose... rather than be told _'all was garbage, give up'_ HI HI Seems a decent CW decoder should track a buffer, so that it can adjust parameters and do "late correction" on previously displayed characters as the senders timing margins become clearer. I think that, and smart tone detection, are probably a software thing and not so suitable for discrete electronics. I could be wrong, but I've yet to see a robust discrete decoder.
