RBN will pick up on the "CQ DE <call>" or possibly just the "DE <call>".
For tests where you're not expecting a reply, "TEST DE <call>" (without
CQ!) should also work. RBN skimmers seem to have a limit to how often
they'll spot a single call, so sometimes you need to change frequency to
get re-spotted.

Is there a procedural write up for updating the firmware on these various kits?
My note here, https://sites.google.com/site/g4zfqradio/qrplabs_program_chip_with_USBasp with a link back to the QRP Labs site. Many examples in the Files section of this group.

Is there a procedural write up for updating the firmware on these various kits? I was looking for a section on the QRP Labs site that included the hex files listed but did not find anything. In my last order a few weeks ago, I bought the c version chip.


Re: Battery level indicator settings ??

Adrien F4IJA
 

Ron, I'm not talking about the alignement tones, but the 9.1 menu which displays the voltage of the power supply, minus the diode D3 if installed (I didn't in my case).

It's using the DVM so I guess the battery level is in accordance with that value.


Re: Battery level indicator settings ??

Ronald Taylor
 

Adrien, the alignment tones are measured at two other points (audio 1 and audio 2) and do not go through that divider.  73... Ron

Hello Ronald,

Thank you for your answer. Anyway, as I've the well measured voltage in the menu 9 (alignement), I guess that the divider is OK. For me, the battery level displayed is taking this value to make the scale so I guess it's another thing which makes this behaviour.

Maybe my settings in menus 7 are not good, and that I've not understood the calculation step or something else ?










Re: CW beacon

Alan, I'm wondering if RBN network will detect a call with no CQ in the TX line.

Vernon : yeah, why not, it's simple for sure.

Hi,
I have used "TEST TEST TEST DE MM0VPM MM0VPM  MM0VPM"  and got picked up OK, cq means you are calling for a qso, so you might get a reply...😊

Re: CW beacon

I've never heard of adding BEACON, but I think I have heard of adding TEST.  At any rate, even if someone responds to your CQ you don't have to have a qso with them.

CW beacon

Adrien F4IJA
 

Hello,

I'm quite new to CW and still learning, even though I've already assembled a QCX+.

I tested yesterday Reverse Beacon by sending my call with that message (stored as a message in the QCX+).

CQ CQ DE F4IJA F4IJA F4IJA BEACON

Is this the right way ? I don't wan't anyone to think I want to have a QSO, so that's why I've added the "BEACON" at the end.

Do you think it's the proper way to send beacons in CW or is there something better ?


Re: QCX TROUBLESHOOTING

Bob M.
 

Can you disconnect the secondary of T1 to check that 2.5V bias voltage? I don't know if the IC it feeds is passing that bias voltage to the circuitry to its right (on the schematic) but I suspect everything along that signal path is DC coupled so if you remove the chip, there won't be 2.5V present for the stuff after it. If you're going to remove that IC anyway, it's worth measuring the bias voltage with it out.

A product called Chip-Quik is amazing for removing SMT ICs. It alters the melting point of solder such that it stays molten long enough for you to grab a component and lift it right off with no damage. It's not cheap but you use so little of it, it's worth the price. They sell it in kits with some liquid flux included. You apply the flux, heat the connections, apply a tiny amount of Chip-Quik (it looks like solder) to all the joints, then lift the part off the board. In the case of an IC, flood the leads and pads with Chip-Quik, even if it's just one row at a time. Reheat it and lift the part off. Clean the board with solder wick or vacuum desoldering equipment then some isopropyl alcohol, and you've got a new clean place to install a new part.

Dear Dave,

Great to hear from you, and great that you have the equipment, and extensive knowledge of the QCX and QCX+! I did not realize you had built so many of these kits! 

I am in Vail, Arizona, about 25 miles East of Tucson. I graduated from NMSU back in 1980, so it would be fun to see Las Cruces again and make your acquaintance, if you ever want an eyeball QSO, or moral support with that problematic radio. BTW- I have a BSEE from NMSU.

I'm going to check out your SuperGrabber website- you must have quite the antenna farm!

Dear Shane,
Thanks for the offer but I have just about the same stuff in my shop to attack a defenseless 4" circuit board and a bunch of parts.  I think I will be able to handle it as soon as I figure out what is going on with it.   The chase is half the fun of fixing it.   Today I replaced the LM7805 +5VDC regulator as it was drooping and wasn't putting out +5VDC.   The new one is at 5.02 VDC.  I also changed the two 10K resistors R1 and R2 with a pair of 1% 10K resistors.   That brought the voltage up to 1.98VDC but not to the 2.5 Volts I was expecting.   Looking at the circuit the only load for that voltage divider is the Quadrature Sampling Detector IC4 a surface mounted FST3253 of which I do not have.  So, I will work on getting a few and replace that one.  This is a case of it is the only thing left in the circuit that doesn't work.   There is also still another mystery lurking around IC7 and IC8 that is also causing problems.    So, It is just a wonder how this much stuff can be bad in just one kit.    I have a 40M QCX that I built that I am using as a comparison radio to check measurements against.   So, I am not without a working model and I still have the 12 QCX's that I built for the Super Grabber that have been RETIRED by the new 12 QCX+'s  that are trudging on running 24/7 copying signals from all over the world.  
Have a nice trip to Vail .   I hope you can get there by Tuesday.   They got a lot more snow up there than we got here.  
Take care and have fun.   I will muddle along with this project and the 4 other ones I am working on.

Re: 40 meter qcx no display stopped working #40m

Shane Justice <justshane@...>
 

Outstanding! So glad to hear you found the source of your problem, and you now have a functional radio!

Nice collection of test equipment! Sounds like ]out have all the necessary tools and experience, as well.

I look forward to hearing you on the band sometime!

I have spent the last 8 days at a dear friend's house, taking care of her after she had back surgery by an interventional radiologist to repair two cracked vertibra. I am looking forward to getting my QCX+ up and running in the next day or so. 

Let me know if you want to try a QSO!

It's a bit too tight to install in the box. I've modified it and I print it again today. I'll let you know when the design will be OK.
