Re: QCX+ only static on receive

G3SPL
 

If you are getting good nulls etc on calibration, and hearing "static" then it looks like the audio circuitry is all working.  Does the "static" change in level when you disconnect the antenna?  It should go much quieter when you disconnect the antenna.  If no change, there is something wrong in the connection from antenna BNC to the receiver input.
Don't forget there are a lot of short wave broadcast transmitters at the top end of the 40m band.  Certainly in the evening, you should get many strong carriers, typically around 7.2MHz.
As mentioned above, you have to set the correct reference frequency - normally 27MHz but 25MHz if using the TCXO.  If you aren't hearing any real signals on 40m it may be that the reference frequency is wrong so the synthesizer chip is producing the wrong frequencies.  Good luck!

It might be a good idea just to make the frequency a little higher, maybe 14,097,075.

Many receivers do not have good calibration and they could easily miss your signal, or report it as being a
little lower in frequency.

And because of that, wsjt (I think) will not send the spot data to WSPRNET :-(

I checked wsprnet a few minutes ago, but no data.

I assume that you have used your callsign in the CALLSIGN field and not the MESSAGE field (this sometimes
confuses people).

Fingers crossed for you.

It's easy to overlook, but have you ruled out the antenna system as a problem? 

Assuming that it's OK, the latter two calibrations inject a signal pretty much right at the BNC connector. So, a continuity check between the connector and the LPF might be in order. 

The instructions warn against having an an antenna connected during calibration, for a reason, it will radiate a signal. Let's use that to our advantage. With the antenna connected and QCX+ in calibration mode can you tune it in on an external receiver? 

I'm still on my first cuppa so I'm not clearly thinking quite yet <sheepish grin>

No matter what religion or faith you quote there will always be someone who thinks they are supposed to be offended. For the perpetually offended I would suggest looking inward rather than trying shout down that which nobody is forcing you to acknowledge. You might find an existence a bit less abrasive.

First, don't worry about those voltages
Julian,

They are taken using the built-in voltmeter function. ~13K input.
But very few actually use it.

Re: WSPR U3S parameter setting info

Thanks Hans, I hope to have some luck, the u3s transmits very well, it is modified with 3 BS170 at 10v and delivers 2w at the output, I do not increase the voltage to 12v because the transistors heat up too much, so I also put a fan for cooling.  I change the frequency to 14.097000 and hopefully someone will listen to it.  73 iu8eun Joseph

Re: QCX WARC Party

Hi Berrie,

Sadly I only copied PB4P? I could not get your last prefix letter.

I have very bad QRN on 30m with noise spikes right across the band, so this made it very difficult to copy signals when they dropped below the noise.

Im still not 100% sure my QCX hasnt gone deaf either unless it is being desensed by the QRN as it doesnt have an AGC.

Hopefully we can work on 20m on my QCX20 and the end of the month.

Sorry guys I did try. Will try again for sure.

Let's review the 3 nullify calibrations. These interact and need to each be done several times. I would check these again, and note that the indicator resales so watch the indicated number that it keeps going lower.

Thank you very much Jesus Christ. In some internet pages it carries different frequencies, up to 14.0976, so I don't know the exact frequencies.  .  Anyway, thanks for enlightening me.

Sometimes I wonder if people who reply to help message even read the help messages properly.

The OP stated what frequency he was using, the WRONG frequency.

It's bad enough users not reading the manual, it's just as bad when people relying don't
even read the request for help message properly.

yes, I'm sure, I entered my name without numbers or spaces.  I don't understand why, I don't wish I had some other setting wrong.  In the afternoon I will take pictures of all the configuration parameters and send the pictures.  I hope to understand what is the problem that prevents the reception of the spot on WSPRnet.org.
