For you Anti-Scopes

It would be great if the P3 provided I/Q output's as well.
Perhaps some knockout plugs on the back chassis panel would allow
various output jacks and facilitate lots of user customizations.

Eliminating the duplication of the same via separate hardware connected
to the buffered IF output would be a real plus.

I actually like sending with the paddles, but using the VFO knob isn't that exciting. If I see a CQ on CW Skimmer, I can click on the text, and it tunes the K3 zero beat on that signal. Or I can turn the vfo knob then spot the signal, using up time for no purpose.  Why not use a tuning aid?

Because I think there is more pleasure in discovering a signal by tuning into it than having a computer point it out to you. And why do we do this if not for enjoyment?

Someone commenting on my blog today put it admirably. He said: "There is a fine balance between enjoying the technology and the way it enhances the hobby, to being over-taken by it and draining the hobby of joy."

[Phil Hystad]

Wouldn't it be better just to get the digital stream that is sampled from
the I/Q signals.  That way, the ADC is done just once.  Then, your computer
can take the binary stream (new interface needed I guess) from the
P3 and then do what it wants with various digital filters and other F/X.

Eric,

That's good but two questions...

1) If you purchase a P3, do you also have to purchase a KXV3A or will
one be included?

2) In addition to the buffered K3 IF feedthrough, will the inphase (I)
and quadrature (Q) audio components of the downshifted IF be provided as
an additional output (ala LP-PAN)?

Thanks!

Ted, W2ZK

Excellent slice of history on celluloid... The courthouse in Dayton Tn still stands.

[Julius Fazekas n2wn]

It was pointed out to me that, as a tool,  a P3/Panadapter/Softrock does provide a quick way of assessing activity on a given band quickly versus twirling the knob.

I can see where this would be useful, particularly if you were looking for openings on 10 and 15, in the past few years. Too, you could assess how solid the opening might be.

Hmmmm, $700... Will have to check it out further in Dayton.

Thanks Gary for the "unsolicited advice"

73,

[David Gilbert]

Why couldn't the P3 have had buffered IQ outputs so that it wouldn't be necessary to purchase extra hardware to run those other PC apps?  The IQ signals have to be there inside the P3 anyway, right?

Er, I thought that was kind of the point of it all. To find and work stations with just your radio using your basic operating skills (i.e. listening) is part of the overall enjoyment?

Try it sometime - I.e. turn on your 400 or even 200hz CW filter and start at the very bottom of the band. Start working your way up very slowly and see how many sigs you can scare up. with a really good RX like our elecrafts, you'll be amazed at what you'll actually find down there right above the noise if you scan manually and slow/carefully..... Or practice starting off with a wider filter to "spot" sigs then keep narrowing as you listen up and down. It's definitely a skill and one that can be quite enjoyable to develop.

I dunno, a scope just kind of takes the fun out of the "easter egg hunt" for me. It is kind of neat for getting a big picture of the activity on the band, but actually hunting them down I prefer to do with just the VFO and the filters like I had to do in The Old Days hi hi.

[Eric Swartz - WA6HHQ]

your K3 will need to have the KXV3 or KXV3a for IF output. Its not
included with the P3 since most K3s already have added it.

I/Q is not available as an output. That would seriously delay the P3
release and add to our cost. Its not a trivial add since its only
derived internally in the DSPPIC that drives the P3. We may be able to
add it as a future option. Stay tuned!

Back in the late 70s when I was working as a W1AW operator, Irv Hoff
W6FFC came to visit the station one evening.  Irv was rather famous at
the time for his work in RTTY (inventor of several popular demodulators)
and later became famous for his work in computers (writer of much early
CP/M software).

Irv loved to talk and we chewed the rag all night, right on through
until the next morning when he had to leave for the Hartford-Windsor
airport to report for duty in his job as a United Airlines pilot.  (I'll
never understand how he could fly a plane on no sleep!)

One of his stories was about his ham station.  Somewhere he had acquired
a surplus DEC PDP-7 (I think it was) minicomputer that he had interfaced
to his RTTY station.  He had hacked a program that would automatically
answer anyone calling W6FFC when he wasn't at home.  It would then
engage in a typical ham QSO, play the brag tape, and respond to simple
questions, all with no human intervention.  It even remembered the other
operator's name so the next time he called it could answer him my name.

He did all this back in the days before home computers.  (The Apple II
was introduced in 1977.)  He asked me to keep the story quiet since it
was technically illegal to operate a station with no control operator,
but since he passed away some years ago (1991) I think he is now beyond
the FCC's reach.  :=)

 My K144XV was shipped yesterday. I plan on using it for SSB as well as
occasional repeater use. My question is I would like to put the FM filter
(for the repeater use) in the SUB receiver. Has anyone who has installed
their K144XV using it on the SUB RX? If so, any problems with this setup?

I like CW Skimmer, but for very weak signals, your ears work better. These debates usually become "PC" vs "No PC".

Using the knob and your ears is going to work best for finding the weak ones, but using the skimmer also has it place. Personaly, I am going to use all the tools I have available, and not worry about it.

I don't see any threat from using technology. It's all fun for me.

[lstavenhagen]

Well I'm mac-only at home so I can't use a lot of the cool stuff like that hi hi. But seriously, I can definitely see how a scope or etc. can be useful for, say, contesting.
And I didn't mean to take away from visual innovations like this for amateur radio. I'm kind of a CW shellback, but that doesn't mean the rest of our hobby should be like me, hi.

I finally got around to watching the video of the P3 display and it looks really neat....

I agree Julius. Sunspot Cycle 24 may be my last chance to enjoy 10 & 15
meters. Looking through a Ha solar telescope reveals a Sun that is waking up
big time. The California QSO party is my objective time to have a P3
up-and-running and to have efficient strategies ready to employ in the
contest.

 

Although I got my Novice ticket in 1957, I've never enjoyed Ham Radio as
much as today. The reason is that a small company, Elecraft, has combined
unequaled effectiveness, reasonable cost, fast upgradability, and
unsurpassed service. The K3 has earned Elecraft a place in the Ham Radio
Hall of Fame. Their success is our success. I'm looking forward to the P3.

On Wed, Feb 17, 2010 at 06:26:26AM -0800 I heard the voice of
Julius Fazekas n2wn, and lo! it spake thus:
>

These sort of statements always make me twitch.  All of (not just part
of) the fun of radio (like of anything) is what YOU enjoy about it.
You (generic you, not necessarily Julius in particular) may get a lot
of joy out of finding a signal, while for other people finding the
signal is a miserable ritual that they just have to put up with to get
to the FUN part, which is talking to the person.

It's no different than some people LOVING building a radio / antenna /
whatever, just for its own sake (and may not even like actually _being
on the air_ much at all, comparatively), whereas for others it's slow
torture, and waste of time that could be spent buying one already
built and getting on the air with it.

    (And don't try to read that as a direct analogy either, because
    it's perfectly possible to enjoy the "lower-level" of building
    while hating the "lower-level" of searching for a signal)


It can be a fine line between communicating "I enjoy X" and "X is the
enjoyable part".  The former can lead to interesting discussions and
comparisons, but the latter pretty much always comes across
argumentative and just tends toward building up steam.  The
complication is that people often mean the former, and phrase it as
the latter.  Lose-lose  :(
