Hi Darren. The 5v PTT signal can come from pin 11 of IC3. The 10 ohm resistor is a good idea to limit the current just in case. One wire is sufficient if there is a ground return somewhere. But the

Sounds to me like you'd wanna send every child and adult to the electric chair just for questioning, and attempting to >validate< presumed authority. Pro-Institutionalization at it's best ;) - 73 de

Anyone who doth complain too much is free to come up with about ten billion in capital to build their own fab, an international logistics system featuring same-day delivery within metro areas (more

That's my plan.? ? ? I seen where there's a post with a modification to the qcx, to add a PTT signal to the amp. I don't remember which locations off hand, but there's a 10 ohm resistor jumped off

Hello, For what it's worth, my QCX+ exhibited exactly this behavior (higher RX current draw and only ~1W TX power) after I accidentally blasted 100W into the antenna input.? On the QCX, the elevated

Every now and again there's a post querying the use of modifying the QCX for other bands. So I've started this thread in an attempt to CONSOLIDATE working mods. That means that you consider your work

Thanks, Curt, for your clarification! 73, Michael DF9TZ

This has been covered before. A small to moderate difference in wire diameter matters little. 10 percent is such a little change. Enjoy your wind and rest of build. curt wb8yyy

Because I cut the wires of the coils quite generously there is only 73cm remaining for T2. That might be too short for a trifilar winding of 20cm effective length I guess. As I have no 0.33mm wire in

Hans, Thanks for the info about the GPS chips, I had no idea there was such variation in the different modules. Did you happen to test the ATGM336H-5N31 GPS module?? This one is used in the Zachtek

Huh? Quad core motherboards without chip or graphics are running near $150. We're getting spoiled, guys. 73 Jim W4JED

Hi Hans, Seems to be my order from may was shipped.? But could not delivered as I was on Vacation.? But I didn't get an info from the postal office,? so the package was sent to Turkey again. Please

why can't you just wire one up?

Here's a chance to give your QDX a workout and try some contesting: https://ww-digi.com/ August 27 1200 UTC to Aug 28 1159 UTC There is a QRP classification. I'm sure the FT8 band segments will be lit

In the 8th grade, we were having our team basketball photos taken, and it ran longer than expected, cutting into my last class of the day. So rather than be late, I went to class in my basketball

Amazon etc don't care about the price gougers. The more they charge, the more commission they get. No different to estate agents. It really IS a licence to print money. - 73 de Andy -

Best of luck in your move.? Thanks for your input and will look for you next year. Bill-N2OII

I am told that you can colour the end of enamelled wire with a spirit based permanent ink marker pen. When I wind, if I have enough time, I tie none, one or two knots in the ends of thin wire before

A wooden paddle works but our shop teacher used a bunch of wooden dowels all taped together. They stung and the vibration of the dowels made a ringing sound when used. Also the teacher never used such
