Take for instance last night. I was trying to work Steve WX2S on 40 Meters who lives about 18 miles from me. Ground wave was strong enough that he was about a 229/339. The advantage was that not only could I hear him, but I could also hear the stations that were calling him. I ended up not working him, but even so, it was a unique opportunity to observe.
Steve was working split from the beginning and he was handling the pile up deftly. But I was left shaking my head, because so many times - all through the hunt, people continued throwing out their calls while Steve was engaging another station! I sat there, kind of dumbfounded. There was Steve, sending out "559 NJ STEVE 5W" to whomever, and all the while there were stations sending out their calls, over and over and over, without so much as taking a breath!
So here's the deal......if you can't hear the quarry well enough to realize he answered someone other than yourself - then why the heck do you continue to throw your call sign out there in the first place? Obviously, if by some miracle, he actually came back to you - would you be able to hear that well enough to realize it and complete the exchange? Something tells me ........no.
Listening. That seems to be a dirty word in the minds of a lot of folks.
Look, I know we all make mistakes and I've made my fair share, too. No one is perfect, and I can understand forgetting to turn the "split" function on or some other such thing. But deliberately sending your call over and over and over in the vain hope of somehow scatter-gunning the target is really just inexcusable, and rude and inconsiderate of your fellow Hams.
As always, this is just my humble opinion. Your mileage may vary.
