Hans! I logged on just to write the list to ask if there might be available a darker print-out of the schematic! Hah, and I find that its the topic of the day...talk about riding the community

Just a small note of caution... Ground and ESD protection are two different beasts. Grounding your body and then accidentally touching high voltage can be fatal. Providing a reasonably high

So..everything was working fine.. Decided to reflash the processor..went from the original up to 1.05 then down to 2 then up to 3 .. that went fine.. but i am having some issues with the rotary

I purchased one of these folding stands on ebay and I think it work very well. Jim

One thing that would have helped me is a complete schematic of the display board. Especially, it would have saved time to have a diagram relating display board JP3 physical pinout to main board JP5

Hi John It's normal. It doesn't matter much what the ref or sys oscillators calibrate too. The size of the error, doesn't matter a lot. The firmware compensates for it. 5.613kHz of error, is what it

Thanks for the prompt reply, One additional question. I have a TCXO, and the Reference oscillator calibrates at exactly 25 000 000; however, my System oscillator calibrates at 20 005 613. Does this

Nice. Thanks Hans. Can you also post the complete schematic of the QCU PCB somewhere? It isn't in the group's Files already is it? Each of the products that use it, seem to have important parts of

Agreed, Greg. I also am in a basement shack with 3 floor/ceiling above me plus an asphalt shingle roof. The walls are insulated with double Al foil sided foam panels. It's like being at the bottom of

A__ is perhaps a giveaway and sounds like the known parsing feature that exists in the U3S as well? Probably the GPS firmware has changed, and they not told Hans...... The LEDs

Hi John This is a known issue, that can occur in the various QRP Labs kits. I actually found the cause and solution to it yesterday! So in the next firmware releases of the various kits, whenever they

Did you enable GPS in menu ( section 8)

Received and built a QLG1 yesterday. When I connect it to my QCX, I don't get the full display as shown in the manual for Function 8.13. I get the following: A__ f__ t12 s40 The Red light is ON,

Just take sensible precautions, it's not necessary to make it a new religion. As a field tech you don't have the luxury of ESD benches & seating, shoes and clothing that should

Also remember that the Heath Cantenna had an air vent in the top lid. The mineral oil and air would expand slightly when it got real hot, and the pressure in the can had to go somewhere. You don't

Thank you so much for sharing with us your wealth of knowledge and experience. While I do appreciate that you probably know the very best ways to handle ESD, I've also found that some professionals

John, I'm in the "basement" of a split level house. One floor and a metal roof over that and I still routinely have 8-11 satellites. Do like Curt said, just try it out. You may need to find a good

If you are going to do much building and tinkering with radios get a color printer or go to one of the office supply places and have them print out the directions. When I retired my gift to myself

Hans, Awesome! Thank you so much! Michael KN6IZE
