Update:? it works now.? The problem was a cold solder joint on the batt(-) pin of the barrel connector.? ?I should have looked more closely before posting!

No I was merely be philosophical and maybe slightly trivial. In spite of my call Dayton is about 10 hours away by car, but I should consider making the trip. Nice there are wares to consider,? perhaps a bunch of Jackals were sold. I honestly need bench time more than a trip.

Bruce may solve whatever it is rather soon. Sounds like a real nice instrument Farhan and his friends have provided. Safe travels everyone.

Re: wsprnet results, wsjt-x, and calibration success --> world domination V4 #calibration #firmware

#68958

This is right where I'm at now. Sooooo many configuration tips and absolutely none of them are the same. I especially loved the one about setting BFO by tuning to static till it sounded "good". ?

Also took me a while to finally realize that even though the config menu options are the same using CEC firmware, they work NOTHING like the factory setup. Finding a partially written manual for CEC clued me in. Using WWV is a great idea, except I live a stones throw from it and WWV is very much NOT NVIS. Gave me an excuse to finally order a proper signal generator.

Re: wsprnet results, wsjt-x, and calibration success --> world domination V4 #calibration #firmware

#68957

There was so much trial, error, fumble, confusion and general stupidity in my process that it is a model of what not to do.?

I distill till the process:
1) express the 10mhz ?freq error as a percent delta
2) apply that percent delta to the weird calibration number in memory manager, reboot
3) remeasure the error (a) if close enough to step 4, (b) if still to far off go to step 1
4) run WSJT-X freq calibration process and apply proposed adjustments
5) if your WSPRnet spots still work at all, consider yourself lucky, if you get lots more spots consider yourself very lucky.

This process took me hours and hours to develop and implement. ?I recall reading about this exact process in one of my late night uBITX reading deep dives. ?But I didn't just implement it. No, I had to invent it on my own at great expense. ?

So as usual, I have discovered what others have known all along.?

Re: treble only SSB modulation

#68954

Hi, just to add my 2p worth. I had this problem and like above, used a dummy load and transmitted an LSB signal. This was received by another rig and showed the BFO was way off.?

I replace the SMD capacitor with a number of others in a number of values and parallels, but could not get the sound I was after. They were all too low or too high in pitch and often just unable to understand at all. Eventually I looked for another set of capacitors and found one from Rapid Electronics. variable 7pF to 50pF SMD. Fitted this and then adjusted it, a bit at a time. until I got the sound I wanted.

Thanks to all here for the help and discussions explaining the fix.

Farhan sold some last night at FDIM (and yes, I have one ;) ). The sign he had implied that there is a ‘normal’ price of $100, and he sold them at a discount, so I would assume that you will eventually be able to order them.?

Hello Adrian,

a good avdice, I'll try this this week-end, as I need to bypass first my AGC board from kit-project (soldered on the slow agc position), who changes a littke the overall audio response...

I'll let you know here.

I have used the SDRPlay as a SA, and had some challenges.

1 - First of all, the frequency span was not big enough to measure the
harmonics on 40 meters in one test.? You need to change the center frequency
to do the test in two separate measurements.? I was not sure that the gain
stayed the same, so I my experience, the harmonics test was inconclusive.
2 - It was not clear how the gain controls operated in the SA software.? I
still am not sure, so maybe someone can be specific on how to defeat the AGC
and adjust the gain for a good capture.
3 - I built the following 50 ohm "tap":

I still needed a step antenuator feeding the SDRPlay from the tap.

uBitx = TAP = Watt meter = Dummy Load
|
L= Step Antenuator = SDRPlay

It has been awhile, but I believe I had to adjust the step antenuator and
gain to insure that when I added or removed 10 db, the SA software reported
the same amount of change (this was how I overcame the AGC issues)

4 - The SDRPlay SA software will warn when you are getting close to
overload.? Even if you stay below the warning message, there is signal
compression even without the AGC engaged (reason for the set testing)

My experience was it was good for close in purity testing, not so good for
the harmonics

Above is my experience, things may have changed, or there may be better ways
to accomplish the task.? Yours may vary.

Re: Low power output on ubitx

#68945

I have check all again, and the rv1 at 2/3 was best modulation but the output doesn't get higher than 4-5W on 80m an 3W on 40M.. the other Bands still get 1-2 on 15M or 10M

THIS CAN NOT BE THE UBITX OUTPUT THAT SHOULD BE THE RIGHT ONE , WHAT CAN I CHECK IF Q90 IS NOT SHORTET I REALLY GONE CRAZY..

sorry this makes real bad vibrations everytime i get outdoor for testing on lagre antenna in the nature and everytime there is no way, or even when have luck it really strong to get qso with this.. and this issue should be able to find but i'm doesn't find till now?

Hope for any idea

Nice

Hmmm - could I buy enough stuff that the discounts could greatly supplement the travel cost?? LOL with that but nice of those merchants to make the gesture.?

selling kits at FDIM implies that the hardware design is complete!? adding a larger display and updating firmware code can be down-loadable.? one can imagine more will come for sale at HFSignals to help fund his long trip to Dayton!? (ditto with QSX for another VIP who was at FDIM).

It takes some time to supply and kit things - nice that some folk at FDIM have first fruit.? They owe use reports after building and using them!?
