GM Gary,
We are fully in sync this morning.
Things are always clearer in the morning than they are late at night.
Yesterday I overlooked two letters in you statement: "tu".
I said it posts when it hears stations calling CQ. (and it does)
You said it posts when it hears stations sending 599 tu (and it does...)
At the time it did not occur to me that in a contest QSO, only one station
sends "tu", the run station. The station pouncing doesn't get a chance to
respond with tu. Just a minor detail with a huge consequence.
The "tu" is the filter used to screen out the stations moving on.
The rest is all OK. We agree.
The advantage of doing it your way is, the local CW Skimmer only posts what
you can hear.
The advantages of using a remote skimmer are simplicity and cost. You don't
need any extra hardware (nothing at all) and if the feature is built-in to
your contesting logging software, it is for free.
As I said last night, the "dead" posts in my band map are far less than 50%
and usually if one cannot be heard, it is obvious. For instance, if it say
KL7xyz in the middle of the day on 40m, well that's pretty obvious that I
won't be able to hear him then.
Sounds like your system works great.

Rick,
A local CWSkimmer can only decode what the local radio hears; in my set up I
have the FLEX-1500 operating off of the OMNI-VII RX loop using the N4PY
sub-RX mod. CWSkimmer is decoding 20 kHz of received signals via Virtual
Audio Cable 4.11.
A number of things impact the CWSkimmer spots in the N1MM+ bandmap see
(http://n1mmplus.hamdocs.com/tiki-index.php?page=Bandmap+Window&structure=N1
MM+Logger+Documentation)
and in the telnet window, see
(http://n1mmplus.hamdocs.com/tiki-index.php?page=Telnet+Window&structure=N1M
M+Logger+Documentation).
These settings, including the spot timeout setting (I do NOT understand why
you would want a 30 minute spot timeout) will change how busy your bandmap
will be. Note that a CWSkimmer feature is simultaneous decoding of ALL cw
signals in the receiver passband - up to 700 signals can be decoded in
parallel on a 3-GHz P4 if a wideband receiver is used - (I'm currently
running an AMD FX-6300 - 6 cores @ up to 4.1 GHz, 8 GB RAM with two 224 GB
SSDs)
Regarding your comments on ever changing callsigns; often the callsigns
change on a given frequency change as both the RUN and S&P station's
callsign are decoded.... there are times when the spot has aged and the
station has QSY'd. I choose to move up and down the band with the VFO,
recognizing that while my I am listening to an audio bandwidth of 200 Hz
using the OMNI-VII 300 Hz Collins filter, 200 Hz DSP, plus an AOR TDF-370
set to 700 Hz CF @ 200 Hz BW and some special curves in both my SIEMENS ITE
hearing aids, I can jump 10 KHz in frequency with the mouse and NOT miss
having a station put on the bandmap by 20 kHz BW of CWSkimmer and the
FLEX-1500.
Rick, as I stated previously CWSkimmer is NOT a solution for a RUN station.
You are correct in that there may be too much data on the screen at times
and perhaps lots of it is garbage. I'll say that few Contest Operators can
listen to a 3 kHz bandwidth and copy everything.... no human can copy 700
signals simultaneously. That said, how do you know that VY1AA or VK9DLX is 9
kHz above or below your present frequency without CWSkimmer or a telenet
spot?

Gary,
Tnx for the input.
Seems strange to me that it would show every call sign.
If you think about it, unless a station is calling CQ, after he sends his
call sign and completes the QSO, he QSYs so he's no longer there anymore.
THIS IS THE VAST MAJORITY OF THE STATIONS! Such a message to the bandmap
would not only be worthless, it would also clutter the bandmap with garbage.
So if it were really showing every call sign it decodes, on any given
frequency, the call sign would be constantly changing. But it doesn't.
For that reason I find it difficult to believe you are correct.
BUT I DO NOT KNOW FOR SURE!

Rick, just a small correction on item --1--
>>> A band map does not include all call signs. It can't. It only
>>> includes the ones calling CQ.
# as I have N1MM configured with my local CWSkimmer as a telnet server
127.0.0.1:7300, the N1MM bandmap is filled by every CW station who IDs
within the 20 kHz bandpass of the FLEX-1500 / VAC / CWSkimmer combination.
Included in the bandmap information Callsign, (color indicating mult value),
time since last heard, and CW speed.
# Also, as I have DXlab Commander configured, I can use the OMNI-VII VFO or
the computer mouse clicking on Commander Control panel or bandmap, CWSkimmer
bandmap, N1MM bandmap, or the FLEX-1500 frequency display. I find using
N1MM's bandmap is easiest and fastest for S&P. As I have said many times,
CWSkimmer is NOT for the run frequency, but can really shine for SO2R, S&P,
or multiplier stations (Multi - two, etc).

--1-- But ... what if the band map does not indicate a call sign for
ALL the blips? What if there are blips that are not labeled?
>>> Indeed you will have lots of blips unlabeled. Many will be people
calling a station that you cannot hear or whose blip is buried below those
calling him. THESE GUYS are not interested in working you, anyway. They
are after that juicy multiplier down in the mud.
>>> A band map does not include all call signs. It can't. It only
>>> includes
the ones calling CQ.
>>> REMEMBER, we are talking about working a contest where the object is
>>> to
try and maximize your score by working as many multipliers as you can as
well as working as many stations as you can. You'll find many of the blips
on the high bands and most of the blips on the low bands are stations which
you cannot work anyway. But you have to sit on their frequency and listen
to them until you find out who they are.
>>> EXAMPLE: late in the contest you have worked nearly 1000 QSO. If
>>> you
see a strong blip on 40m, it's probably some guy you've already worked.
With a bandmap you would know, but not with a bandscope. If it is not
someone you have already worked, then it's probably someone in your
continent - say a Mexican station. If he's in the US, "you" can't work him
anyway. But you can work a Mexican station. If you work him, you get 1
point (because he's in the same continent) and multiplied by all of your
multipliers, you score goes up by about 300 points. OR, you are focused on
the band scope, skip over non-multis and focus only on the multipliers that
you have not yet worked (in a new country or zone or both). Work one of
these, since he's outside of your zone, he counts 3 points, and you score
will increase by something like 1500 points (depends on several factors, but
you see my point). That's because of the complex way of scoring.
>>> So the bandscope finds targets when we're shooting at anything that
moves, the bandmap helps us work smarter.
--2-- Besides, I think Larry N8LP (the panadapter guy) already provides
just an overlay for the NaP3 program - it works with a skimmer or cluster or
something -- see here:
http://www.telepostinc.com/NaP3.html
>>> WOW, NOW THAT IS NEW TO ME. YES, BARRY'S DREAM HAS COME TRUE!
THANKS FOR THE TIP, JAMES!!! All the more reason to move into the next
level of ham radio!
I'm going to research that because I know nothin' about it.
So I think the future is here already. (By the way... I bought the LP-Pan2
for one of my other radios...) ;-)
>>> I don't even know what an LP-Pan is. Maybe my XYL has one in her
kitchen. ;-)
