OK, Hans? cool...
If you need a tester :)
i have unhealthy amounts of time on my hands at the moment hi..

What nights and band/freq are you on ?Opera2? Would like to try to spot you. 73

Ernie,
Been bouncing back and forth between Opera 40m and testing this FT8 on 6m band.Looks like 6m is not too bad but have to run around 50 watts.
The big stations seem to be working 6m which helps.Seeing the same stations as I did when MSK144 was popular.My simple dipole is doing ok.
I do not have to setup the U3S for 40m,I only used that band because there are no others anywhere else :) Maybe 3-4 total each day using 40m band.
I`ll setup elsewhere if you have a band in mind?

You might try Dale, WC7S. He can be contacted at daleputnam@.... He has done kit building for our customers, many times.

To fill a band with automated beacons may be pleasing for an individual for a short period of time, but in the grand scheme of things it's QRM. Our bandplans are very flexible because we behave responsibly.
If you are interested in propagation, WSPR is the obvious choice, its a few hertz wide rather than 50Hz.

David,
Yes WSPR is the obvious choice.
It seems to me that many of the other mode "grabbers" are to alert users that a QSO with a spotted station is possible rather than just to test propagation?

I wonder if there was an automated voice recognition program available, would it be acceptable to leave a voice keyer running 24/7 using up 2kHz of bandwidth just because there are 'vastly more people receiving'?
Thanks

yes Hans, I know that need to change R according to the table from ke7xr.
thus, menu items 3.8; 4.8; 8.2 i make 500 Hz.

Jim-

Jan,

I know all about those very tiny lost tracks fiddling with T1. Glad you were able to repair!

Your earphone jack may be shorting to ground (Know issues). Try removing the electrolytic just before the socket and putting in circuit with an external socket. That should prove the fault. I also suspected IC10 but it was much simpler than that :)

Hi all!
gentlemens, I want to change the center frequency of the CW filter.
I can not understand whether I need to change menu items 3.8; 4.8; 8.2; 8.3; 8.4??because by default they are made for a frequency of 700 Hz.
if i need to change, what values do i need to set menu items??for example, the filter frequency 500 Hz.
in the manual, nothing is said about this ...

Not sure what your saying.The quote was from my post saying ,why not have FT8 beacon for U3S?
JT9 has fewer spotters as does many other modes that came and gone...so yes,FT8 in the U3S is a good idea since there are more people listening there.
I run my U3S using Opera2 on 40m...not because it is a good idea but because the mode does not require a GPS for timing and the only mode for non GPS.
But there is only a handful of spotters using it.
FT8 shows lots of stations making it a bit more usable for QRP.
I personally think there are enough QSO modes available to now they are consuming the bandwidth with a splattering free for all mess.
QRP folks do not have a chance anymore below 1 watt...sad stuff.

About 6 of us in the local club are building the 20M
version as a club project.

Mine are for 80M and 40M, so I won't have a QCX there,
but I could dial my "big rig" down to 5W. We might be
a bit close for 20M though. Of course, that's assuming
you can send slow enough for me!

Just a suggestion... I found it tricky soldering the
single pin headers in place. If I was doing it again,
I would probably install them right at the beginning
when they weren't surrounded by other parts. Sticking
the pin in some dense foam might be a way of holding
it upright while putting the PCB down over the pin to
solder it.

I put the male pin header on the LCD display instead
of the female connector (a la BITX) so I soldered the
female connector on the QCX board. The stand-offs are
a bit long. You would think I would have learned from
the first one, but if there's a third, I'll sand about
1 mm off the stand-offs before adding the LCD display.
That way, the header can just be pushed flush down
onto the LCD display for soldering. With the stand-offs
a bit long, I ended up pushing the pins a bit further
through the plastic part of the header, so the short
pins made it only just to the top of the LCD circuit.
I used the LCD circuit board to push the male pins
down into the connector and then soldered them.

Good luck with the club project!

What good is running a QRP beacon if there are no receiving stations to spot it? All I have to do is look on PSKREPORTER and run through the modes to see who is actually there.So far,looking grim except for FT8.

Precisely my point!

The more coverage you have, the more it represents the prevailing propagation.? Likewise the faster reporting.

Just program a short beacon message, like JT9, JT65, etc. So a FT8 beacon.?I'm not sure how useful that is...

It's useful because there are vastly more people receiving/reporting the FT8 signals and therefore giving a more realistic picture of the prevailing propagation on PSKR and other sites.? Fast or not, if the beacon's signal's received, it's reported.? That's all that matters.

You're learning nothing about that when only two people in North America are using some moribund mode...like JT9 has become and JT65 is very rapidly becoming.? Even WSPR use seems to be declining.

The complaints I've read elsewhere about a FT8 U3S don't make any sense...especially when coming from these disruptive idiots using 1000W on a mode intended for QRPp in the first place.?

There's no -- ZERO -- obligation for a QSO if CQ wasn't called in the first place, ever, in any mode by any means.? This is experimental use of a digital mode and there's nothing wrong with that.? If you use JT65 in beacon mode (which I do), I don't see the difference with FT8.

FT8 for a U3S beacon makes absolutely perfect sense to me.? If I'm missing something here, please explain it to me.
