P3 and SSTV

Sometimes when I have idle time on my hands the mind tends to wander off, so
with this in mind please be kind ok?..:-)

Could the P3 become a SSTV decoder and display a digital image?..The is a
program proving quite successful called EasyPal and it got me to thinking
that if future expansion of the P3 features will include a PC keyboard I got
to thinking what else could be added.

Given the room available my thought was that this could be achieved.

To load an image perhaps a USB port or USB/Serial connection to store SSTV
images.

Certainly there are ways to use the K3 with a simple connection to a PC but
when you are operating in a remote are or DXpedition environment the ability
to TX/RX SSTV would be an added bonus.

Anyone got any comments?

How many expeditions do you know of doing SSTV? :-) You're asking for a very narrow and specialized application to be done with the P3's dedicated (and relatively small processor). If Alan attempted to put the processing power, memory and flexibility of a PC inside the P3 you probably wouldn't like the price.

Buy a laptop for $2-300...and don't hold your breath waiting for Alan to put one inside the P3.

Re: P3 and SSTV

Even more basic, why would a DXpedition want to bring a P3 along? Extra
box, weight, cables and no benefit.

Re: P3 and SSTV

Why would a Dxpedition take an extra keyboard along to plug into the P3?

Why did Elecraft add QRQ to the K3?

I guess it's fair to say many of the available features in products today
are ignored by many and I am sure there are other 'features' that are not
used by many.

It was just a thought after all.

Nuff said, end of thread.

Re: P3 and SSTV

In reply to this post by Gary Gregory

Actually this was an idea Wayne had some time ago. The P3 is just a
software-defined radio so adding an SSB demodulator and SSTV decoder is
certainly possible. The color display would be very nice for displaying
the images at full resolution.

One issue is, which SSTV format(s) should be supported? There's the
traditional analog black-and-white format from long ago. A number of
color analog formats have appeared over the years, including various of
AEA's AVT modes, a number of Robot SSTV modes, and several flavors of
"Martin" and "Scottie". Should the P3 support decoding VIS mode tags?
And how about digital modes?

Another issue is what to do about transmitting? I believe the K3DVR
option in the K3 can record up to 90 seconds of audio, which is not
quite enough for a frame in the most popular Martin M1 and Scottie S1
formats.

If we want to do this I think it would have to be receive only, probably
supporting only Martin M1 and Scottie S1. It would still be a cool
feature.

Re: P3 on DXpeditions (was P3 and SSTV)

In reply to this post by alsopb

I was all set to take my P3 to CY0 with N0TG and crew because I had
convinced myself that it would be the perfect tool for pile-up management as
the DX station. I even went so far as having (very nice) matching K3/P3
cases made up by Rose. The P3 case has sufficient remaining room for
cables, keyers, paddles, spare batteries, small tools, and cans, and is a
convenient complement to the K3. Unfortunately the trip fell through
because of weather and everything below is still theory.

I figured that I could use the P3 to look around any given band
before I started creating a pile-up to see how much damage I might be doing,
and once I found the best (i.e., least offensive) portion of the band, I was
going to use the Span adjustment in Tracking Mode to set the upper boundary
of the pile-up so as to be able to contain the mess without worrying about
undue growth.

Then I was going to use the QSY knob regularly to drive the K3, when
required, to quiet areas of the pile-up and/or also to search through the
pile-up for my next target after I had finished with the one that was
already in the queue. Both were intended to assist in keeping the rate up.
I was also curious to know if one could become as proficient with the P3
using the QSY knob in the Tracking Mode as one could by the conventional
method of tuning around with the K3 and listening only. One certainly can
use that technique successfully in S&P contesting and I predict that one can
learn that skill in DXpeditions such that one was not always stuck with a
single method when running pile-ups.

As a contribution to the overall operation, I had a multi-band wire
dedicated to my K3 and I intended for all operators to use that with the P3
as a decision-making tool when moving around the bands at their stations.
Maybe catch an odd opening that way at a time when such occasional openings
were starting to show up in the current cycle.

Finally, I was guessing that the P3 would be the perfect tool for
keeping QRM off my transmit frequency since interference would be so
obvious, and I could then use a little TX frequency agility to dance around
them.

This was before the introduction of the P3 Fixed-tune Mode which
probably would have made things even better again for a P3 nut.

I heard a DXpedition recently in which it was clear that the
operator was monitoring his TX QRG in something close to real time, so
perhaps someone has now already used a P3 on a DXpedition and can report on
its utility for that purpose.

73,
Gary, VE1RGB

Brian,

I will be QRV at Undara Volcano National Park (VKV-01) with a complete
K-Line so will let you know. May 18th-May 24th, 10/15M openings to the US
expected to be good.

That's a very responsible attitude (although the same result can be

Fixed-tune mode is excellent for pileups, except that all the
information is crowded into the right-hand half of the screen because
the DX operator is normally listening UP.

A very useful option would be a 'SPLIT UP' mode, like fixed-tune but
with VFO A fixed at one division from the left. That would allow us to
view the pile-up at the highest available resolution, spread across 9
divisions rather than 5.

No problem. I use ONLY fixed tune mode. I have the Fixed Tune toggle
programmed to a soft button. When I'm working a pileup or a contest, I
tune the radio to the middle of the range I want, set the width I want,
then hit that toggle twice, once to switch it back to centered tunable
mode at the dial frequency, the second time to put it back in fixed tune
mode. Works great.

If I'm setting up for a contest, I do that for every band before the
contest and the P3 remembers the settings. For DX chasing, I set the
vertical scale for 24 dB; for contests, I use 42 dB. The only thing I
need to change after the contest has started is the bottom of the scale
(the reference) as band conditions change and the band noise rises and
falls.

You can Hold CENTER and move the DX station's freq to the left edge of
the display and set SPAN so the pileup is spread across the whole
display. The two controls interact some but it is easy to do while you
are listening to figure out the operator's pattern.

Re: P3 on DXpeditions (was P3 and SSTV)

You're going to do this while running a pileup 1000 callers deep?

DXpeditions exist to make QSO's, not watch TV.

If a DXpedition is having trouble making QSO's, a P3 isn't the answer.
Improving their antenna(s) and being aware of propagation most likely is.

Thanks, Fred, that works for me. (Jim's method also works, of course,
but yours is closer to my normal habits.)

I already have four different SPAN settings pre-programmed into the
function keys, and one of those is always close enough.

Re: P3 on DXpeditions (was P3 and SSTV)

In reply to this post by alsopb

Brian,

Most of the comment so far appears to be focused on the hunter, not the
DXpedition.

On the next effort we intend to use the P3 on a receiving station monitoring
bands we are not using at a particular time. Many Dxpeditions do not have a
huge number of operators. If you mean a Dxpedition to a rare and much sought
after entity then that is a different situation entirely. Some of these are
able to operate many if not all the bands and modes they are set up for,
others have to rationalise the number of bands and stations and with this
scenario a P3 would be of assistance.

SSTV for example is a mode just like digital, cw, phone and rtty and granted
it is not as common as the other more popular modes but it is a mode
nonetheless operated by many.

Advancing the P3 technology to encompass as many operational modes as
possible is a plus and should not be seen as a restriction right?

I have a request to send SSTV from our next effort and the computers are set
up for logging and it would be nice in the future to not have to take a
PC/Laptop for this.

But we will transmit SSTV images during this operation and we are making
arrangements to do this. Will it be popular, well I guess we will wait and
see how it goes and have a look at after the event.

It will be fun to do it though so I am looking forward to trying it out.

All the input so far has been positive and some good ideas have come up
already. It's all good eh?

73's to all,

Gary

SSTV is not recognized as a separate mode in the DXCC program - or as
far as I know in any major DX award program. It "counts" as phone for
DXCC. Why would any significant DXpedition waste time on a "slow rate"
mode?

Will it be "popular?" I would expect it to be *extremely unpopular*
- particularly if the location of the DXpedition is to any place on
the "top 200" needed list. Spending as much as 3 minutes per QSO
on SSTV when good operators can make ten times as many QSOs in the
same period on SSB/CW/RTTY makes any SSTV operation extremely unwise.

Re: P3 on DXpeditions (was P3 and SSTV)

In reply to this post by alsopb

My motivation in taking a P3 to CY0 was not to overcome difficulty in making
QSOs. Based on two previous DXpeditions to CY0, I was more interested in
making my life a little easier in the face of unlimited and sustained
pile-ups which start to get to be a bit much after three or 4 days. I
think the P3 would have done that for me, not to mention provided the other
features I mentioned earlier like, say, the ability to watch my own TX
frequency. I always wanted to be my own frequency cop. Or to defeat those
who think that tail-gating is the only way to make a Q in a pile-up.

There is another reason to use a P3 if, like me, one is used to operating at
home with a limited station and always being the weak signal. When on a
trip I like to pick some of the small signal DX who one can guess are
equally deprived, and the P3 allows one to see those kinds of stations quite
easily in the pile-up.

No matter --- our friends from the opposite side of the planet are going to
provide us a report after their experiment. Maybe we will discover that
ears are the only answer.

Re: P3 on DXpeditions (was P3 and SSTV)/DXpedition version of P3

I would prefer the room for other things in the travel bag instead of
the P3. All of the things you would like to do can be done with the
radio alone. In split mode you can monitor your own transmit
frequency. There is not much you can do about what goes on there and
the UP UP UP ers will probably beat you to the punch.

What I see that causes the most problems in pileups is the DX not IDing
enough and not announcing their split enough. Even then it does not
matter as there a growing number of ops that can't copy cw and just see
a spot and send away as they don't understand what up is. On RTTY T31A
was sending UP every contact and still people continued to call on his
xmit frequency.

Trying to work the weak guy is admirable but I don't see how the P3 is
going to make that any easier. All you need to do is set a split range
and then let the masses who blindly call do that in that range and then
pick out stations on the edges or above the split range. You can tune
around in your split range for lighter stations if you want. If you can
easily see the weak station in a pileup the pileup can't be that big.

Don't get me wrong I love my P3 as it has put a bunch of contacts in my
log by being able to see the last station worked.

Maybe we need a DX-pedition version of the P3. There is no reason the
case needs to be as bit as it is. If the case was shrunk down to a
third of the size I might consider taking one.

Re: P3 on DXpeditions (was P3 and SSTV)/DXpedition version of P3

To me it was all about easily providing the operator with alternatives to
nothing but the receiver alone that might ease the pressure of the
DXpedition workload. That would have lead directly to increased throughput,
in which case everyone would win. An experiment based on selfishness but
with fringe benefits, in other words.

Like I said, I never got a chance to try it, but I do enough contesting and
DX work with the P3 that I was confident that I would gain something out of
it. The P3 would have been the source of real-time, real-world, quickly
obtained, multi-band local propagation conditions to the other operators if
nothing else and a P3 on a DXpedition might be worth the weight for that
purpose alone, especially during QSB conditions when the waterfall is so
useful. Band change decisions should have been easier.

That was my answer to the original question about why would one want to take
a P3 on a DXpedition. Chacun à son gout. There is no right or wrong answer
and I am in no position to provide hard evidence to support my own argument
:) Anyone want to organize another CY0?
