The P3 Effect

Has anyone else noticed just how many people are now able to pounce on the last frequency TX5K used? Back in the day you swapped VFOs and listened for the calling station. After I got my P3 it seemed to be a real advantage because you could instantly find the calling station (if you could hear him). Now so many people do this it seems to almost be a requirement to have a P3 or panadapter of some sort. Of course, I could be wrong.

Re: The P3 Effect

Perhaps this is why DXpeditions seem to play "spin the dial" more; having many stations converge on the last rx frequency probably tends to slow their rate. I experienced this effect at PZ5RO. It would be interesting to get feedback from DXpedition ops.

Eric,
This seldom works for me as so many are constantly calling a DX station
that determining who is supposed to be there is difficult. I have to tune
and listen with the K3 and sometimes this is not so easy when so many
stations call continuously. I tend to use the P3 to find a relatively free
frequency to make my call from. Maybe this is a problem in Europe only but
I doubt it.

The P3 remains a powerful tool which I would not like to be without!

It's called "progress". It doesn't have to be a P3. Look at the ire
the use of SKIMMER has generated.

Now guys have to figure out how to intelligently use the new gadgetry.
Working DX will still be an developing skill. Those without the
technology will moan and complain about it being unfair of course.

Which brings up another technology. Remote operating. The advantage
there could be huge. But in the future, many will have no choice. So
how do we judge remotes?

This has also been my experience. In a pileup where the DX is listening up, I can see on the P3 that many strong stations just keep on sending while the DX is making an exchange. What is with these operators? Is it because they do not have QSK amps and cannot hear the DX while they keep sending?

I think the concentration of the pile-up on the last worked station
is due as much to CW Skimmer which highlights "5NN" as it is to the
P3 and other panadapters. Given the skimmer behavior, the panadapter
seems to be an even greater advantage as it allows one to identify a
"hole" near the last worked station ...

I certainly feel "blind" when using a rig on the workbench without
the P3!

Re: The P3 Effect

In reply to this post by WD6DBM

I can not say I find the P3 is at all useful in chasing DX, NOT the fault
of the P3 of course, it's the abysmal operating procedures of those
continuously calling or replying to the DX when it's clear he is calling or
working another station. All the P3 sees is a mass of simultaneously
calling stations and it's impossible to see and pick out (most times ) who
is actually working the DX.
The 2nd Rx is indispensible in my opinion and I'd rather have that than my
P3 any day.
Of course the P3 has other uses but for finding the Dx listening QRG?

Re: The P3 Effect

I use both the P3 and the KRX3. P3 gives me a look at where the alligators
are so I can quickly disregard them and the few remaining pips I can
quickly check for real QSO activity. Sight and sound.

Alligators are very annoying, they also seem to be largely those with huge
signals (either they're all my neighbors or they have full gallons) and
huge skirts/clicks. Seems to be a pattern there...

Re: The P3 Effect

In reply to this post by ai2n

I prefer to operate CW with the receiver bandwidth very wide, AGC off and ride the RF gain manually. With the receiver set up like this I can hear many stations spread out and pick them off up and down the passband without having to do much tuning. On Swains Island this technique worked quite well at NH8S.

Having been " out there a few times" I know I spin the dial usually after
1-2 Q's as dual receivers and other tools brings the pileups to who I just
worked . I will usually jump the edges, then jump the center and repeat that
in odd combinations. Today one cannot listen for the gang on one frequency
very long...so it's always " keep moving"

Re: The P3 Effect

Yes, that was my experience on Conway Reef last year. I could only work a
given RX frequency for a couple of Qs before having to hunt for a clearer
call and start again. I began to notice that the weaker signals that I
could copy tended to be on clearer frequencies, so they would be my guide to
where to start again. It seemed to work pretty well as I did a fellow who
said he was running 1W on 20M SSB. I think he was from the level of
excitement in his voice.

I've had really good luck working DX by calling at the upper edge of the
pileup. As the DX op I would often just go 'up' to the upper edge to find
a clear call, and I think a lot of other DX ops do the same when the pileups
become a roaring wall of noise.

Re: The P3 Effect

I agree with working the edge of the pileups.
I have been to St.Croix, not exactly a dxpedition, over a 4 year period.
I bring the K3 with me.
It still amazes me that I work 1,000 plus stations each year, get requests
for QSL's with GS's and a bunch through the bureau.
For some people, KP2 (Virgin Islands) must be a new one.

I do work split most of the time, especially on CW and RTTY.
And if the pileup gets rough, I work the edges.
I'm not a big phone guy. On SSB, I operate simplex.

Funny story:
In 2011, on my first day in St.Croix, I was working a pileup and getting
great reports from Europe and the U.S.
Later in the day, I found that I was only running 30 watts. Apparently the
K3 thought I was still hooked up to the KPA500.
I increased the power to 100 watts and the K3 shut down. I found out that I
had a bad power supply (PS was in rental shack) and could not exceed 30
watts.
With 30 watts and an A3S, I still worked over 1,000 stations. Of course the
rental (NP2N) is high on a hill and clear signals to EU and US.
Yes, there's an amp in the shack, but decided not to power it.

Fwd: The P3 Effect

Good story Bob.

I'm always very interested to hear how the heroes at the sharp end of
DXpeds handle the pileups, strategies etc.
What does it take to get 'in the log' ?
We have the best of equipment, and great software aids, and I've had
reasonable success but there is always, always, something to learn.

50 years in Amateur radio this year and still magic !

Thanks to Elecraft for rekindling that magic spark... but T9 of course !

Re: The P3 Effect

In reply to this post by WD6DBM

I use the P3 to find an open spot. My best use was during the
NAQP RTTY contest when I discovered that a station from the my
last-uncontacted state (N1NK) was always beating me to the top
of the pileups. He Was tuning up, so I found a spot with the P3
just above where we were working and started calling CQ. He
called me and I have LotW and a card confirmations. Thanks N1NK.

I would like to hear what digital DXpedition operators think
about how to work pileups and how to behave in pileups. Some CW
operators have just said they use a wide bandwidth, and it seems
from looking at my P3 that CW callers tend to spread out, so an
operator can use the pitch of the CW to separate stations in his
or her head. Frequently you can hear several SSB signals on top
of each other, and hopefully tease out at least a part of a call
sign and ask for it.

With digital, if several stations are transmitting on top of
each other nobody's transmissions will decode. Is there anything
we as callers can do to raise the QSO rate of the DX, which is
to everyone's advantage? TX5K's digital QSO numbers for are a
lot lower than for CW and SSB, and I don't think it is only that
they spent more hours on the air in CW and SSB than in digital.
It seemed when I was monitoring them their QSO rate was lower in
digital. Would PSK31 do better with it's narrower bandwidth than
and more room to spread out than RTTY? There is no end to the questions.

Cheers - Bill, AE6JV

Re: The P3 Effect

In reply to this post by ai2n

It's still as tough as it's always been, just like a hailstorm of callers
for which you need a good rx and even better ears to sort out. As the
population of P3s and other panadapters expands, more random listening might
help, rather than ploughing a furrow.

I could not agree more the days of twist and shout are over for the shack,
but for portable with my KX3 it's fine.

For better or for worse, most Hams have moved beyond the days of sitting
quietly in front of the receiver and tuning very slowly across a seemingly
"dead" band listening for the whisper of a signal.

For me it was at once a frustrating and a magical experience far removed
from today's shacks filled with huge flat panels displaying the activity
across the band at a glance, the computer screens showing the latest
activity reported on the internet, and rigs that QSY anywhere in the
spectrum at the touch of a single button.

As an old pilot, for me it's the difference between floating through the sky
in my J3 "Cub" with little more than an altimeter and a big windshield in
from of me and visiting a modern airliner cockpit filled with glass panel
displays and computers actually doing the flying while the pilot sips a cup
of coffee.
