This may be more germane for CW - think weekend after next - but it's worth remembering that the cluster network only resolves frequencies to the nearest 0.1 KHz.  Seems to me that given calibration differences among cluster nodes, that operating on frequencies ending in .25 or .75 almost guarantees that half of them will spot you on .2, while the other half spot you on .3

Seriously Stan?

I just made 4,682 qso's (after dupes) last weekend in CQWWSSB and I can guaranty that almost none of them were on frequencies ending in .00, .25, .50. .75, on ANY band.  And, while I was running most of the time, the stations were not calling me on .00, .25, .50, .75, either.

Even when I was S & Ping, the stations were not CQ'ing on .00, .25, .50, .75.  They were using what relatively clearer spot they could find.  I don't even know of anyone that operates the way that you suggest.

"Fractional frequencies?".  There is no such thing.  A frequency is a frequency regardless of what number it happens to be.

Doug,

Although I agree that it is permissible to use fractional frequencies, if you will observe what is actually being done, not just by new ops but also by old-timers, is that most operators choose a SSB frequency ending in .00, .25, .50 or .75. Therefore, if you are doing S&P, you are *most likely* to
be on frequency with the CQer if you set your dial to one of those
settings. If the signal is not right, then tune off. But, *most likely*,
you will end up .25 away.

I have done a lot of S&P while I was a little pistol and it is rare to find
someone not on a multiple of .25 with SSB. It's not a rule, but it is a
fact.

This is especially easy to observe if you use a large screen panadapter
(such as Flex SSDR) where you can *see *where a signal is.

So, when running, you may park wherever you wish, but when doing S&P, you will tune onto a calling station faster and more accurately if you use the
.25 technique.

and here's another spin on the subject...

A lot of newer operators seem to think that we are supposed to operate on "channels" on SSB - another words, exact kHz frequencies like 14275.0, and will only call on those frequencies, even if the actual frequency in use by
the station they are calling is 14274.67.

I am not making this up. I have seen posts in various places observing that someone heard a station on 14274.67 and thought it was wrong ("Shouldn;t he
be on either 14274.0 or 14275.0?")

As a result, these callers are off the CQer's frequency, necessitating the
use of RIT.

Few if any of those guys are reading this email list, so please take the opportunity whenever you are speaking about contesting to your local club,
Elmering on FD, or wherever, that it is OK to be on a fractional kHz
frequency!

Somebody's gotta teach them!
