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??

I can notch him out and he can do the same to me. A couple of hundred Hz separation should be all we need.

Lol just messing with you now. No offence. On a serious note though, even with my limited cw surely it is possible to answer a QRL back in cw, providing you at least have 2 wires and a paper clip to slap together if no key hi hi. (I do have some keys now, but I used a paper clip on the desk for my 1st cw qso ) Also isn't there something about sending your ID in SSB /CW anyway. I also read this and thought, hey most digi mode software will send an cw id and or you could use computer generated cw to check if the frequency is in use. I am so desperate to get my cw receiving up to scratch so I can use it freely, I wish we had still had to take the test back in 2004 to be honest. Maybe we could sked a qrs contact some afternoon / evening.

On all the rigs I've owned the filters are selectable. 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. In my opinion. Dave (G0DJA)
