[digitalradio] Re: Considerate Operation: CW and JT65A
Hi Andy et al., I agree with your statement. On 80m I observe some stupid fellow trying to QRM with carrier howling and cw-dots on 3576 kHz when there is JT65 ,mainly between 18z and 21z. I have suffered absolutely no broken QSO even if that QRM was in the middle of the signal or spot on the guide tone, but I can imagine that a less experienced CW-op could get confused by jt65 or similar mode overlaying his QSO. vy73 Fred DL6XAZ --- In digitalradio@yahoogroups.com, Andy obrien wrote: > > I often "look" at the CW signal on the waterfall when I hear one close to > me.

I agree with that, and I see modern day rigs have a tremendous amount of filtering capability. I'm talking about the likes of the 756 pros / FT1000 s / ts2000's etc etc and other such radios that would take a small mortgage for me. I notice that these have variable band pass filters and the like that could probably narrow the pass band to a few 10's of hertz enough for a single cw or bpsk31 signal. I suspect that these work on TX also ? Like me and many many others who run older equipment without all the bells and whistles though, as you say. I was always taught to listen first and then listen again. Although just remember that we don't all have the super dsp and notch filters on our radio's. Out of interest, do common filters work on TX or just rx, and if not why?? ---Original Message--- From: Andy obrien Date: 22/02/2010 11:32:36 To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] Re: Considerate Operation: CW and JT65A I often "look" at the CW signal on the waterfall when I hear one close to me My view is...if his signal is not exactly on the same part of the waterfall as mine, we are "OK".

Are there any radios that have only very narrow CW filters, or are the 'on/off' buttons difficult to operate? ;-) Taking tongue out of cheek, as I do enjoy CW as well, saying that people with digital modes can, and should, listen 1st and look at the frequencies around them, the same should be true for CW operators.

I guess it's a case of not being a legal requirement, but a nice record to have. OK on 2M, it can be the same down here at times. 2M SSB only seems to get going in the summer and those of us that prefer CW tend to have to wait for Aurora and Meteor Scatter to really kick in. Anyway, I think were getting off topic for this thread now. Dave (G0DJA)
Re: [digitalradio] Re: Considerate Operation: CW and JT65A
Dave, I knew about the logbook but not the cwid or /m /p etc hmm. I am getting out of touch. The only time I can see not using a log book though is when /m but that's just me. I love looking back over the past 6 years at old qso's and seeing if I have a (new one hi hi ) When I was first licensed March the 5th 2004 everything was a new one and I think for the new breed of M6 / M3's etc it would be a shame for them to not keep a log. Ok I don't log every single net on 160m or VHF for example, but pretty much every contact still goes in the log, I bet you are the same. VHF is such a shame up here in the outer Hebrides, took the puppy for a walk yesterday and up the hill I can see most of the isle of Lewis for 2m, not a single reply even through GB3IG which I though was quite sad for a Sunday afternoon. There must be at least 25 operators on the island and the repeater can work some distance out to the NW Scotland. I don't have a 2m antenna up at the MO and this was quite sad to not make a single contact. Oh well.

Yes, I had an IC706MKIIG for a long while. Maybe it was the poor location of the filter button that made me get rid of it? HI. Here in the UK the requirement for CW ID was removed several years ago and the latest UK licence is a much simpler and very cut down document. There's not even a legal requirement to keep a logbook anymore and the /M or /A or /P suffixes are 'recommendations' that people 'may' use. These are mentioned in the notes to the licence, not even in the main body...

Re: [digitalradio] Re: Considerate Operation: CW and JT65A
I often "look" at the CW signal on the waterfall when I hear one close to me. My view is...if his signal is not exactly on the same part of the waterfall as mine, we are "OK". I can notch him out and he can do the same to me. A couple of hundred Hz separation should be all we need.

[digitalradio] Re: Considerate Operation: CW and JT65A
Andy I am both frequent another forum that is CW based. The subject came up over the weekend about a two tone mode in the vicinity of 14077 kHz. Andy pointed out it was probably JT65A. The other commenter found it annoying with two other CW signals in the bandpass. I almost jumped into the discussion, but held back. I think the commenter was inferring the digital signal was interfering with the CW signals. It all depends on who was there first. Also it wasn't certain that the two CW ops and the digital ops could hear each other, although the commenter could hear all three. I think sound card mode ops can easily look for nearby signals, on the waterfall, for the period of a few minutes to get an idea of the activity. The same is not true for CW ops if they have narrow filters. Some rigs have dual peak filters for RTTY. There could be a signal in between the filter peaks and the op could never hear a signal in between. A couple years ago, I answered a local buddy calling CQ on 40 meter PSK31. After the QSO, one op made a scathing comment about his qso in progress being qrm'ed. I didn't reply. From my perspective, I had heard a CQ and answered it. My local buddy should have heard the other qso as well. I did email the guy and apologized. It is much easier for the CW op to hear other signals when they are running full or semi breakin. Digital ops don't have that luxury, as we transmit a few minutes on and few minutes, depending on the speed. Perhaps TOR mode ops could hear other signal between the bursts, if they are not automated. CW ops usually call QRL? to see if the frequency is in use. How do digi ops do that? How does the digi op reply to a CW QRL? query? There will always be QRM, even with the best of intentions. We should try to minimize as much as possible. I operate both digital and CW and don't see an easy answer. 73, Steve N6VL
