Hi, I just got a disturbing mail from Yahoo. If I understand correctly all content of our group will be deleted and the group will become something not open to public. Exchanges only be e-mail and

Hi Tim, LightAPRS-W does not go sleep as much LightAPRS. It's because WSPR preparations and TX. WSPR TX takes 2 minutes and preparations starts 1 minute before. So no sleep nor APRS TX during this

George, OK, although they should be easy to source. But I am thinking that further faults may be found if the voltages are checked. Maybe look at again sometime, you learn more about how something

one last thing... soldering iron. The average one I see in use by people is a reasonable quality temperature controlled unit turned too far up with a cruddy tip with rough edges. Replace the tip

Mustafa: I just received my tracker and am very impressed. Looks great. Very easy to get running. Doing power measurements, the unit never draws more then about 320-350mA with Vbat at 7.4v or

What did you use? I do not advise using any of the no-lead solders. They do not rework well and generally need more heat. More pain that gain. The standard here in my lab is the same for the last

Allison, I built my last QCX with poor quality solder and had excessive sputtering and was not satisfied with it. Please recommend a solder that you have had good performance with. Preferably

I use LM2596 DC to DC converters all the time. Their performance is dependent upon load… so beware! Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner -

Us old farts that have been in the industry for 30 or 50 years have seen it. Its common to hand soldered items. You have to be looking for it.... Solder with internal flux can often spatter. It

They are real. Likely your asking them to do something they are not happy with as supplied. I have a bunch of them loose (spares) and more in service. However I took the time to do two things

Sverre, I tested one of mine and found: 78 mv ripple at 68 KHZ. I guess that mine is a fake LM2596 too. Probably most of those $1.00 Buck converters are fake. Thanks for the link!

Hi Geoff The stray resistor leg was one still floating around after clean-up - I have been building electronics things on and off for about 45 years :) I had enjoyed the kit for about 24 hrs - and,

Hans Unfortunately it is impossible to perform quality control on assembled kits at the purchaser's location. Also probably impossible to perform knowledge tests on those assembling the kits. Even

Hi Hans All understood and appreciated. I was obviously unlucky and hope that I am the only one :) Just thought it could help someone else - as, although I was disheartened (still excited like a young

Got mine many years ago. But I checked.....you can get small spools on Amazon, for a fair price. Yellow, green, red on this page,

Great news. I have several spools of 'Phelps Dodge' copper products. All HAPTZ (the good stuff). Where did you buy this colored wire? THANKS for the info.

Yellow, green, red...I have different colors in various gauges. ....Dave

It is a kit builder's requirement to do incoming quality control not the suppliers or kit manufacturer. It is a very tough business, and considering the state of the bands QCX is an amazing

Never seen magnet wire available by color... Perhaps a task for a 'sharpie' marker?

Hi Geoff , Nick You are far far out of date OM... current quantity is 8,885... Thanks Nick... You should play the lottery OM. But avoid thunderstorms, they say lightening doesn't strike twice but...
