OT: Solderable Preformed Breadboard Jumper Wires

kg4rul@...
 

I have been breadboarding using solderless breadboards and preformed jumper wires.  I can buy protoboards that have the same hole pattern for more permanent applications.  However, when I move the jumper wires, from the solderless breadboard to a protoboard, I find that the wires are extremely hard to solder.  Does anyone know of a brand of these wires that is readily solderable?

Yeah, I just didn't have enough space/wires/strength/whatever to also measure the supply voltage.

Perfectly happy with 40W. Never hear the difference on the air between 40 & 50. That's how people blow their amps - trying to
eke out every last watt, for bragging rights.

QLG2 Received

As I'm reluctant to pay more I opted Turkey Post, postmarked 21 May received today.

Fitted LCD, forgot R12 but (right now) it works fine without it.

USB driver in W10 usbser.sys I guess generic?

Try to compare receive noise with and without the amplifier powered up, but I imagine you are just fine. Make some qsos, 40w is plenty and its a fun ride.

Roger that - I was thinking of the QLG2-SE which I think is direct to the GPS chip.

So you might try here: https://www.st.com/en/development-tools/stsw-stm32102.html
Quoting from the site:
>  OS versions prior to Windows® 7 are compatible with the Windows® 7 installations included in the package.
>  Starting from Windows® 10, the STSW-STM32102 driver is no more adequate and the usage of the native inbox driver is recommended.

Jim,

Sometimes I use a butane cigarette lighter here in the shack.  I never smoked but it is convenient.  I also use it for heat shrink tubing on occasion when the hot air gun is overload.

Best Regards,

The QLG2 is sold. The QCX-40 is available for 70 bucks shipped. Factory built, 5.6 watts with 13.6 volts and in a Bama Tech case with Bama Tech legs. Works great.

Re: Missing CW characters for the decoder

I believe in the UK there is now more freedom to choose a callsign. For a summary of the history and the range of prefixes in use see https://www.g3lrs.org.uk/training/callsign-types.html

The licence structure in France has varied over the years. For the current position best refer to the REF-Union site https://www.r-e-f.org/ which should also link to the licensing authority (ANFR).

When I applied (in 2006), new calls for foreigners were usually in the F5V... series or sometimes F4V… I don’t know what happens if you get an F5V call but later are granted citizenship.

QCX Amp Tested

jerry@tr2.com
 

So here I am with the QCX+, the amp, the bird wattmeter, a Narda 30db attenuator for a dummy load, a temp connection to the laptop PS, and an old Fluke 77 to measure the current.

The quiescent current of the amp is 12mA. I did the trimmer adjustment as specified, then started transmitting. Am seeing 42W output at 5.5A DC current.

If I hold the key down, the current quickly drops - so does the output power. By 5 seconds,
it's down to 40W. And the current down to 5.2A. I didn't hold it down any longer than that.

I suspect junction heating of the final transistors makes their gain go down. Should be fine
for ordinary CW.

one of the best translations into French is Balladeur for Walkman but most todays youngsters would not know, what that is.


Re: QLG2 Display problem

Dean Smith
 

This goes via stm chip.
MIni vna uses simular system so drivers should be out there.


Re: QLG2 Display problem

Rob Giuliano
 

Well, that part of it is a USB driver problem (I know, obvious).
Windows 10 is quite good at finding and picking drivers, but Windows 7 expected the user to do all the work.

I don't own one of these (yet?), so cannot say what the USB virtual COMM chip is to tell you the correct.
If someone has connected their QLG2 to a computer and post what driver Windows uses, he may be able to fnd it.

Some producuts use generic drivers like: FTDI (FT232), Prolific (PL2303), CH340, or CP2102.
   I have a Ublox Neo-M8N and it uses a uBlox driver which can be downloaded from their website.
   I tried the ebyte.com, but did not find any drivers for this.

The French language class was divided into two groups, male and female, to try to work out for themselves if it is La Computer (feminine), or Le Computer.

The men's group decided that computer should definitely be the feminine gender (la computer) because: 
1. No one but their creator understands their internal logic. 
2. The native language they use to communicate with other computers is incomprehensible to everyone else 
3. Even the smallest mistakes are stored in long term memory for possible later review; and 
4. As soon as you make a commitment to one, you find yourself spending half your paycheck on accessories for it. 

The women's group, however, concluded that computers should definitely be masculine (le computer) because: 
1. In order to do anything with them, you have to turn them on. 
2. They have a lot of data but still can't think for themselves. 
3. They are supposed to help you solve problems, but half the time they ARE the problem; and 
4. As soon as you commit to one, you realize that if you had waited a little longer, you could have gotten a better model. 

The women won.

Now isn't that typical: I've tried to teach my wives that they just need to know that I'm wrong but tell me I'm right :-) not without much success. Try teaching a cat, in fact, felines and females are very similar.

In fact, it was hard enough trying to get all the wives to accept one another let alone accept me. In the end I had to let 3/4 of them go. 

And don't get me even started on "VK Land" --- I don't know if it is this bad in the "rest of the west" but in VK most male hams cannot even operate as they're not allowed to, unless the XYL is out at bingo...

But for that I find the solution very simple, put your foot down:

"Honey, would you rather I go down to the pub every day with my mates?"

Now TURNING the subect to CW - I have a question. Why is it that most females dislike the sound of CW? Though I've known at least one male radio ham to do so to. Is it because it is one single boring tone that is always either on or off and not somewhere between?

Re: QLG2 Display problem

KEN G4APB
 

Hi Hans and all, 
thanks for the info. I get the attached message in bootloader or USB connection. However, it does show up the USB flash drive. Unfortunately, I do not have Win 10 on any PC, and did not realise that was a requirement. 

My display was left over from a U3 Clock I upgraded to a 4 line display so should work.
None of the above really bothers me as I only bought the QLG2 to provide time and freq control to my QCX-mini, which it does.

I am a tinkerer, so tried the other options out of curiosity, but I don't want you to spend any time trying to fix anything. I already have two clock units so I don't need the display to work.

Re: Alignment Problems #40m #help #qcxmini #alignment

 

Yes ! When I power up the radio there is a constant oscillation even with the volume turned down.  I can adjust C1 and its in the proper place at 8 Oclock, but the alignment steps with R27,R24, and R17 do nothing.  I also verified they orked properly before installing

yes this is a rev 1 board.  I replaced the voltage regulator from the original to a 78m05   and did not install the other capacitors as in the notes  


i do have the crystals verified as working 20,000, 25,000, and the calibrator works.  


i literally have been here in the workshop ALL night. Its 5 am.  Im pooped lol. 


all the chips are working and there is half voltages on pins 1&7.   IC9 has 4 volts on pin 1. Pin 7 was 2.4. 

(im using a 9v battery right now).  When I do more testing Ill use the required 12 volts.  


i have looked for shorts. Everything is fine.  The Toroids are all good. I have checked and triple checked what I can do with a DVM.  


need to purchase a cheap scope.  

im literally stumped. 


thanks for the message i appreciate it.
