Doubtful it is a problem. His NS-40 of 10 years ago used the same PC inductors. I still have mine. In fact, I used it to learn about Class E amps. Super simple, very innovative little rig.

All the kits I've bought from them have performed well.

LCD Bezel

m0bmn
 

Hi Guys

Sometime ago we had a discussion about bezels for the LCD display used on many mepts, well I needed a bezel for another kit I sell myself so in the end I came up with this simple one, its made from black finished PCB Board and custom made for me to the size I wanted, black on both sides but could be sprayed any colour you wish (but you would have to do that), I am ordering a decent qty of them for my projects but would like to make them available to all that want one, the cost, its expensive! 50p plus postage at cost, I would expect 3 or 4 boards would be about £1.06 (UK Postage rate) happy to send DX but postage at cost , I guess less than £5 so put a order together for you and your friends if dx, makes sense

If any interest let me know so I can order more than I need, it takes about 4 weeks for the boards to come and Christmas will not help that., no one send any payment just let me know if your interested and I will post again when the boards come.

Thanks

That was when you were simply using it? Not updating?
Someone else has seen this.

Had similar problem. One chip programmed to T1.03 correctly. 3 others all said 'Use original chip!' Or simply displayed a single line of blocks after trying to upgrade firmware. 


BTW, ALL the chips were 'original' QRP-Labs QCX chips that had fully functioning T1.00e/f/or g firmware on them before.  Two of them had been upgraded to T1.00g before and all had worked fine. 


Any ideas on how to recover or at least not 'brick' my single remaining working chip when I try to upgrade that to T1.03?

One other thing, the single chip that worked was a 328P chip while the others were 328 plain chips.

A clue.
" Let it be" is a good song.
"Watching the Wheels" is another league.

 Perhaps my imagination got boosted when I ran the QCX with a 20 volt battery.
But I am glad I did.

Make sure you have the proper board selected (i.e., Tools --> Boards from the Arduino IDE menu).

I’m assuming it’s a QCX you’re describing.

Was it “use original ic” or as you’ve described it?

Have you tried to upgrade the ic version?
And that’s when you’ve seen the text or is it a completely random event? 

James. 

Re: Scanning feature for QCX

Everything I've written since I retired is Open Source and, for me at least, doing so is a true dilemma. That is: Two choices, both bad. I'll bet Hans has waded through the same decision-making process.

If you make your code Open Source, you lose control of it and it does end up being stolen, sometimes for profit. Even worse, some people will attempt to modify your code and, when it doesn't work, they actually have the audacity to ask you to fix it...for free! Not good...not fair.

On the other hand, if you don't make it Open Source, some people think you're a Grinch because they can't make your code do exactly whatever it is they want it to do.  They, too, want you to add such-and-such a feature, but fail to realize there are not a lot of deaf, blind, people who only speak Latin. (The Grinch Factor, to me, is a myth. It's my code...you don't like it, write your own.)

So, what's the answer? First of all, given what Hans has managed to stuff into a Nano, there can't be more than a few bytes left. So, my guess is that putting something in means taking something else out. For most of us, that means "Leave it alone." However...

The QSX is going to be another beast altogether, since it will be using the STM32F4 series of microcontroller. Hans has some headroom there because of the memory resource depth and a faster clock. Yet, from Hans' perspective, how does he address the dilemma of lost control versus the Grinch factor? I think the best solution is an API--Application Programmer Interface. An API provides entry points to methods that allow you to extend the functionality of the program in much the same way that libraries allow you to extend the Arduino core. The downside is that it takes a lot more effort on Hans part to provide an API for us.

So...what's the correct answer from everyones' standpoint? I don't have a clue.

Hi,
As pointed out in another post I doubt there is sufficient memory left. The radio has a remarkable set of facilities and Hans has done a brilliant job on it.

Someone suggested that the software should be open source... that would enable others to produce cloned versions of Hans' work - in effect he does the work and someone else steals it and profits from it.

Tuning up and own the band is good exercise - I remember when we had to get out of our chair and walk across the room to change T.V. channels and there were only 2 or 3 of them.

The facilities available from these little radios is amazing but there is not the infinite capacity to keep adding stuff from "wish lists".

My opinion:
Frequency scanning and numerous memory channels are the most useless transceiver features.
Especially if it is for single band and mode.
vfo A/B enough.

Re: Scanning feature for QCX

Don, ND6T
 

George, I should imagine that it could be accomplished by some additional hardware. Perhaps that would simply plug in. All you would need to do would be to parallel the "up" switch connection on the rotary encoder. A simple '555 timer in astable mode could do it. Add a switch to power (or de-power) the circuit and maybe a speed control if you wanted to get fancy.

Re: QCX Displayed Frequency vs CW Offset #qcx #manual

How I calibrated my qcx 40 was to listen to 7.0475 and compare both sidebands I adjusted the frequency calibration until I got the tone the same by ear on both upper and lower sides.

Although not true laboratory grade I figured that the ARRL transmitter was as reliably close. as anyone.

You could use the I and Q signals. Port them to your computer's sound card. Then with SDR software you got a waterfall display.
