Hi Alan :),
After I start JS8CALL, I monitor ALL.TXT.
A simple graphing tool could monitor propogation by plotting 'snr' of the individual stations.
Another tool could present live conversations.
Both would add a lot to the JS8 presentation.
I just turned JS8 on. No response to my @allcall query call transmission.
I guess most folks don't leave their RPi JS8 boxes on.

Dear Peter,
good idea to simplify.
To state it even clearer, does that mean:
QCX to non-QCX 1 Point
non-QCX to QCX 1 Point
QCX to QCX 3 Points
Right?

I'm new to Wspr. I plan to buy a QRP Labs kit for Wspr. Is there a tutorial on how to set it up and use it? And which one should I purchase? Gary, The U3S is for WSPR, among many other modes. Can be setup for all bands, just one or many sequentially. The manuals are comprehensive, help from this group very good. Assuming you also want to receive the RX module should be added or use your shack RX with WSJT-X. I think some use the CQX but that is more of a compromise. 73 Alan G4ZFQ

Hi Samuli
Did you connect a wire from the DVM pin to the power supply? Forgetting this is the most common reason for empty icon...

Was this ever solved for you? I have the same problem with my unit. Battery indicator always shows empty. Although the radio is working fine.

Re: 50+ Watts amp for QCX...
Hello Allison?
Three things that kill MOSFETS fast, as in BANG!
Excessive gate drive, Excessive drain voltage, Excessive drain current.
Pick any one!
With the MOSFETs I was using I didn't think any of those should apply. I think sloppy layout and the enormous gate capacitance may have contributed to cause oscillation instability that caused one of the three!
My PP HF amp using 2 irf510s as linear with 28V on 40M will do easily 55W (at 2W drive)
and during initial build blast testing with 4W I got to 85W (at 32V)into the load, pushing
further I fried the devices but at 38V and 4W it did do 110W, for about 10 seconds.? Clearly
that was class C Saturated power.? Replaced the pair and since then (2006) dialed the PS back
to 28V with 4A current limit I've not fried any?despite opens, shorts and other oops errors.
I nominally run at 40-45W using it.? Gain is about 14DB without attenuator and the
attenuator is about 2.5db (matches my radios) and max drive is under 2W.? ?Look at
the WA2EBY/K5oor design.
Yes my results closely match yours. I estimated a 15dB gain (Class C bias) and my attenuator is ~4dB so 4W deom the QCX comes in a bit under 2W. All very close...
I wasn't trying for Linear operation only CW. Otherwise there's a few components I wouldn't have omitted, and I would of course increase the bias to get some decent idle current. And more attention on layout.
I have studied the OZ1PIF 6m amp too. These IRF510s are great devices indeed, when treated right.
Was great fun!

Re: 50+ Watts am for QCX...
Hi Hans
?
I applaud your ingenuity and QRO does have its place alongside QRP ¨C a lot
of us do both.
?
In regard to exploding mosfets, about 15 years ago a good friend, with my
dubious assistance, built a couple of versions of Dave Pick G3YXM¡¯s Throbbatron
amplifier ¨C see ?
?
In the original version, after eating a couple of
FETs, my mate got the amplifier working nicely and stably on 160m CW by using
quite a lot of bias, but I foolishly and insistently kept pressing him to get it
working on SSB as well.
?
He then rebuilt the amp with lots of safety
features, removed the bias and, hey presto, it ate IXFH58N20s
in a fairly spectacular and absolutely continuous manner.? The amp
now sits in a corner of my shed looking sad.
?
There is a lot of black magic and luck when it
comes to making FET amps. What we learnt is if you get one working, don¡¯t change
the design!!!

Re: 50+ Watts am for QCX...
Three things that kill MOSFETS fast, as in BANG!
Excessive gate drive, Excessive drain voltage, Excessive drain current.
Pick any one!
FYI 25V to 28V is the ceiling for 100V fets under most high SWR or reactive switching
conditions.? At 30V and higher I've gotten more power but at the expense of higher
probability for failure under adverse conditions like high SWR.
My PP HF amp using 2 irf510s as linear with 28V on 40M will do easily 55W (at 2W drive)
and during initial build blast testing with 4W I got to 85W (at 32V)into the load, pushing

If you want serious power out, OZ1PIF 4x4 of IRF510 and it does a nice 200+W at 6M
at 28V for one module.? He runs two with combiners!
Oh, 5W into 50 ohms is more than a IRF510 can take without it immolation.? Keep the?
applied gate voltages under 12V (DC plus RF peak) or else.

Thanks Graham,
I think my Google fu must of being on vacation
Not sure how the NT7S work passed me by, unless I assumed it was matching hits for the WSPR code..
I'll have a look, libraries are generally several magnitudes out of my depth.
At best I can cobble two bits of well commented existing code together. Maybe blink & something to sound a speaker in sympathy.
Opening up the search description gave plenty of hits for other platforms,
some blue pill's & and blue pills to maintain excitement not necessarily WSJX related......
FYI, if it's of any use.
running on ARM platform, but employing a 5351 and chose to use a Hans reference frequency of choice 27Mhz as well!

John,
it's super hard to understand a word of what you're writing,
but,
if you're transmitting FT8 in DSB modulation, you're definitely polluting the band with the unwanted sideband which cannot be decoded (it's a spectral image), and causes interference with other signals at the same frequency.

Oh Poo. I forgot to change my address and contact info with the FCC. I need to do this right away. I'm overdue. I got my license while I was living in Cal City but I live in Kingman Arizona now.
As for Learning code, I need to hear the sounds and have my brain recognize the sounds as a letter or whatever as a gestalt. I have the same problem with the word/letter thing. For instance, my call sign is KK6LOP but for me to hear Kilo Kilo 6 Lima Oscar Poppa I still need to stop and think which letter it is for each word. This when I already have a hard time remembering call signs long enough to write them down as I hear them. I have to hear something a LOT of times to remember it more than a few seconds. It sucks because I know I'm not stupid but it sure makes me feel stupid when I can't remember stuff. It's bad enough that I asked the doctor to check me out and see why I can't remember things. I had an MRI done on my head today.
When I took my license test 4 years ago I was amazed at how much theory I remembered from my one and only electronics course during tech school for the Air Force in 1970.
So I am sure I need a tutor program to say the words and have me select a letter. As I explained to one of the other members of the Mohave Amateur Radio Club I'm a touch typist and I don't spell the words when I'm typing. I just think the word and my fingers decide which keys to hit.
I'm sure I need to hear the individual letter's code and learn not to hear the dots and dashes and simply hear the letters and punctuation.
Email I'm using for this group is chrisbuyer@...

Just a thought, I'm 68 but a new ham, Haven't made a
contact on HF yet although I have talked a lot locally on
VHF. I bought the QCX kit on 20 M and I don't know code but
I intend to give it a try. I was just going to build it
because it looks like a fun build project. I'm currently
waiting for a magnifying glass I need to see the small
markings that I would have had no trouble with 20 years ago.
Or maybe I would have, components have gotten smaller as my
eyes have gotten older. Can you guys give me a good site to
learn code? Maybe several to try and see if one works better
than the other?
Thanks

K1JTs WSJT-X? v2.01 does all the bit shifting? :>)
Both CW (audio) filter (caveat 3) and DSB (caveat 2) discussed above
Reino om3ma solved my biggest concern? (caveat one above and post above)
This is/was proof of concept / a decision maker for me / to finish my next QCX build :>)
