Hi Justin Negative. Doesn't feel comfortable, to me... 73 Hans G0UPL http://qrp-labs.com >

I just wanted to mention that I regularly work DX with QRP, such as this past Sunday morning, when I worked VK7CW, but there isn't so much as an inch of coaxial cable involved in either of my antenna

I have an older QCX 40 with T1.00a firmware that worked well. After many unsuccessful attempts to upgrade the firmware with AVRdudess and both a programmer and an arduino, I gave up and ordered a new

Don’t forget one of the most important parts of your antenna system, coax. Buy the best you can afford, because there can be a lot of line loss in your coax. So when your running 5 or less watts

Hi Curt It would be possible to download from WSPRnet, all the data. Then do an analysis of how many spots occur at each slot past the hour. If you did see spikes at 00, 10, 20, 30, 40, 50 minutes

So for now I’m set for 0 and getting lots of spots. I guess I should just leave it there unless people aren’t picking me up? ?If you want to check my spots my call is KC3HJP. ?I think I’m

i recognized a kind of jitter when using a TMP36 Sensor. The displayed value changes up to 1,5 degrees ! I tried blocking C's in the power supply and directly? soldered C's from the output pin of the

Hi Mike, it does ! The Kit uses the standard NMEA sentences, Hans described in the firmware manual. Without the PPS you just won't get a blinking heartbeat symbol. But if you use an other GPS source,

Based on my experience, and I am no expert, it depends on what part of the circuit you are using your toroid. For example, if you are using one in an oscillator, you may have to add or remove a turn

Hallo, one question: Does the clock accepts the serial information from the GPS when I do not connect the 1pps signal? 73 de Mike, DJ9BX

Thanks Tom, I'm addicted too! All - I have updated the manual now to fix the typos which several people had pointed out, so far. 73 Hans G0UPL http://qrp-labs.com >

Curt The ordering is Frame Start (as the menu name says). Both must be even, since WSPR takes 2 minutes to transmit and the protocol specifies transmissions start on the 2nd second of even minutes.

Hi Curt. I am not in front of my u3s at the moment. One of the parameters is the start minute and the other is the length of the frame. So if for example you want to start your frame at 4 minutes past

Now that my QCX40 has been expertly repaired, I'm in a hurry to make an enclosure from materials i have on hand. Wondering if i should bond the aluminum parts to the circuit ground. Any advantage?

Hi guys, I got my Deluxe 6 online last night. I mainly work WSPR and I’m getting a lot of spots on 40 meters.? I understand the first part of Frame Start, I have it set or 10. The second set of

The other day I worked Belgium on 20 meters with my uBitx and a home built end fed wire that’s 44’ long and only 10’ off the ground. He was giving most people a 5-9 report but gave me a 5-5

Hans, I'm addicted to your kits:), ordered two. Will be ordering two qsx RECEIVERS when the time comes. TNX Hans for keeping the hobby bubbling.
