Before you flash the U3 did you check what Roger suggested. Is the U3 working fine before transmitting? Can you go through the menus etc.. Have you tried a different PSU. What PSU are you using first.

Dam it James, I think you hit it on the head. No I didn't flash the arduino. What a Dumass I am.I will do the arduino? and try it again. Some one smack me up side the head. I'll let you know. Carl

One of the first construction projects from the ARRL Handbook was a 30ft tilt over mast made from 2 X 4s! Al – K8AXW Sent: Sunday, July 15, 2018 7:26 AM To: [email protected] Subject: Re: [QRPLabs]

That's a good call Roger.

Hello Carl. Have you tried a reboot of your PC after installing the libusb.dll. Also, are you selecting the arduino from the Avrdudess drop down menu. I'm assuming that you have flashed the arduino

Are you sure that your power supply is sufficiently robust? I had a similar problem with my u3s; changing the power supply fixed the problem. You might try putting a 4700uF cap across the power and

I am looking for help installing firmware on my U3s. I am using Arduino IDE as the ISP. Also using Avrdudess. I had a hard time getting the libusb0.dll installed but now have it in the two windows

Steve, Changing QCX CW OFFSET has no effect on the filter center frequency or bandwidth. Brady, Assuming you bypassed the onboard filter (discussed above) there is no reason QRP Guys filter will not

It shows how to adjust the cw offset, so i was wondering if that also changes the filter(s) peak frequency. JS6TMW

Peter LB0K I do not know of any free DGPS code that might be available, but Black Cat Systems does have information available that could help to build something workable:

Have you watched the video? Hans does not appear in this video, nor is there anything about how to adjust the filter. ??????

John,? Thanks. That's probably more involved than I'd like to get, but I ordered one of the $15 CW filter kits from QRP Guys and am going to try it off board. If it doesn't work, I'm not out much!

I got hooked on radio about 63 years ago when i found a lovely crystal set that my father had built in a miniature cigar box. Wish i still had it, just perfect for a QCX. Steve Fabricant

I wooden expect it anytime soon! JS6TMW

So when is the ARRL or RSGB going to bring out "Practical Woodworking for Radio Amateurs" ? ;-) I'd buy a copy ! 73 de Andy

Arv This subject seems to drift off thread so I'll limit myself to just this reply. Setting up a new ref station for a DGPS service would be an interesting project. To whit, getting a new station with

Brady, Audio filtering in the QCX is fixed and way too sharp for my CW and WSPR pleasure. I built several outboard audio filters with great success. Take? a lQQk at this site

I believe if you watch Hans video it explanes the filter settings in the later part of the vid. Carl https://www.youtube.com/watch?v=_Y89tMETDsQ

Came out really nice. Wood is good! I have three radios and a laptop(Rpi) in wood cases.? Couple of things.? Michaels,? AC Moore?and others sell wood boxes hinged lids, same for Amazon.? Some are

Brady: Beautiful work! I particularly like your box joints! This gives new meaning to the term “boom box.” :) Al – K8AXW Sent: Saturday, July 14, 2018 10:27 AM To: [email protected] Subject:
