[Fists] When Zero Beat Is "Wrong"

O K Y'all humor me
Here is one for the guy who admitted he is a little new. I'm still a little
new myself but here is a trick I found in a book somewhere (probably an old
version of the ARRL Operating Manual but I'm not sure, I am sure this is in
print in more than one place) and have found it to work in actual use. Again if
this is old hat to you forgive and ignore me here.
Aside from working "split", when a station is running a pile and obviously
listening a ways up or down the band (or even on another band) sometimes one
hears an ongoing qso where the two stations are not zero beat and wants to
work one or the other of them when the qso ends. In this case, one would zero
the station he does NOT want to work. Especially if your own setup is not the
big gun variety, you want your sig right where the station you want to work is
listening and that is where the station you don't want (the one he is
finishing up with) is transmitting. Even 50 cps off on your transmit frq, can make
the difference in getting him or not. If the station you want is a long way
off, use RIT or even split as needed to hear after you get your xmit frq where
you want it. One way is to put vfo a on one of them and vfo b on the other,
then you can flip which vfo you transmit with depending on which station calls
qrz when they are done. If you must call way off to get him and it looks
like it's going to be a ragchew, ask him to zero up on you to minimize the qso's
occupied bandwidth. If it's just a basic qso like the extreme case of Field
Day, there's no need to worry about it; just swap info and move on.
Like N1EA said earlier about the very narrow filters, you can use them to
pinpoint the place you want to transmit when needed. You keep narrowing the
filter and tweaking the knob and pretty soon, if you're off at all, you lose the
guy so it's very precise.
Also, some guys will be listening off their xmit frq when cq'ing. Maybe they
left the RIT on. You'll have to move around some to make them here you if
you really want them.
Of course, you want to be courteous and call the station that is "running"
if one of them is but if it's a normal qso and they are both signing off, you
call the one you want. I'm sure someone will think you should qrl? first but I
have found this to work and if you time it right, you don't interfere with
anyone. If you don't care which one, then you just wait to see if one cq's or
calls qrz and answer him. If they both clear off, then you call qrl? and cq
between their transmit frequencies. About half the time, one of them answers
you but this is slow and they don't know you were even listening to them. I
always answer when someone calls me but I pass up a lot of cq's.
On the split thing, in the case of trying to bust a DX pileup, well, that's
an art. The DX will be moving his listening point around a bit and you have to
listen to the stations he is working and figure out where to put your sig in
the pile so he will hear it.
And that's my partly coherent ramble for the next little while :)
