KN sent as “dah-di-dah-dah-dit” is an invitation for named station to transmit.
Often it is sent when several stations are calling you and you have only understood a partial call from the mix.
e.g. M?0??F KN invites MM0FMF to reply or MW0AAF or anything with letters matching. It would be wrong for GM4TOE to reply as he has no matches just as MW0HGY does not end with an F.
I write as it would seem not all CW operators understand this. Which was why it took me 5mins to work HB9DAX with the QRM & QSB on the frequency along with the other station who just ignored the KN and sent his call. I think I tried 4 or 5 calls of HB9D?X KN before I could get the call from the QRM and QSB. HB9DAX was trying his best and this other station kept calling me over the top of him. Grrr!
Even if you don’t know what KN means, when a call is directed at something which does not match letters in your call it means you should SHUT UP AND NOT SEND till a general invite is made again. I was on the point of shutting down at this point but that would only punish the good ops. So I stayed active. But angry.
Today I had to go into plain language to request a specific callsign ONLY, asking others to QRX. Thankfully the majority complied with my request so I didn’t have much of an issue.
A short while later, when I asked for the /P station I heard calling, three replied… all /P. Thanks to all concerned as I managed to work all three. One did go away for a while and returned when it was a little quieter.
Very annoying Andy I agree - you could try sending KNNNNN which sometimes works.
It could be rudeness or just a self taught operator Morse operator (like most of us are) who is trying to run before he can walk and who either cannot copy anything other than his callsign and 5NN or who hasn;t learnt the handful of prosigns one needs to get by. I hope you have dropped him/her an email via the address in QRZ.COM to point out your frustration and the wasting of time and extra lost contacts that you could have made if you hadn’t had to overcome his inept operation.
I have to assume the majority do not know what it means, to account for the many, many times I have heard a station CQ, then wind up with “KN”. Nonsensical, of course, as, in context, it means “Hello anybody, but please nobody call me”
Under such circumstances (a station coming back to me with non- matching calls) I usually slow down significantly, tell the mob to stand by (QRX or AS), twice ore even three times. Then repeat the phrase ‘M?0? ONLY’ at least twice.
My perception is that ‘M?0? KN’ will be ignored by some operators.
If they are not calling zero beat, it is also worth trying to move your Rx- frequency slightly (RiT). Sometimes it helps extracting the wanted signal.
This is - of course - working around the problem. Excellent operators only call if they are sure that it’s their turn
I don’t think it is just CW, had the same on 40m SSB where I had part of the callsign but a station where none of the letters matched kept on replying. Ended up doing a long cq and starting over again…
I agree. Those of us who learned the prosigns might bemoan the decline in their use but we are swimming against the tide. I have rarely heard ‘AS’ on air. You will save more time (if that’s what you care about) sending plain language and slowing down than repeating your prosign five times.
You could also send QRT but I guess most folks may mistake it for you going OTA/ VA or CL.
One issue appears that there is quite a different understanding & usage of some pro signs, abbreviations and Q codes amongst some hams.
