I just finished building my v3 QDX. Prior to T2, all of the continuity checks were okay (which is an improvement over my initial v2 build). On T2, however, things were different. The checks specified

Thanks Ted KG5TED

Hi there. How do you measure the output? With a wattmeter of with a scope? IF you have a scope (AND an attenuator!!) please check the shape of the output!. If it is a solid sine-wave, that already

Hello Colin The protocol is described here http://qrp-labs.com/flights/s4#protocol - there were a few minor changes but the bulk of it is the same and the information here would allow you to decode

Hello, I'm new to this forum and need help with the QDX tranceiver from QRP Labs I have just assembled one and would like to run it together with FLDIGI on a Raspberry Pi 4. Assembly was easy thanks

Hello Ted At the moment we cannot get SIM28M GPS modules and are looking for alternatives. So I cannot provide an estimate right now. 73 Hans

I missed the 13:00 session and 19:00 in the beginning no chance on 30 m and moved to 40 with PA0CMU Carel and F/G4IOR. Thanks to the Discord page I knew they were around. Later moved back to 30 m and

Colin Assuming you don't have a short between center and outer conductor, I still wonder about having connections at each T1 winding. Reflow may not cure an issue. On one of my qcx I manually scraped

Does anyone know if and when the U4B will be back in stock? I am flying one now and is doing great. Other than my design of my solar panel. I used Power film cells and they don’t work that great.

Hi all, thanks for the suggestions made to solve my issue relating to not being able to peak my BPFilter. I have watched the youtube videos and read as much as i can on the issue. It seems the 40m

Thank you John, I can find all the spots at :02 but there is a second transmission at :04. It should contain the 6 digit maidens-head locator, the altitude and the GPS status. I am not sure how to

I guess I don't understand why you think js8call isn't documented. It's fully open source. In most open source projects, you do not get much more than this:

TNT driver went to the wrong house but kit arrived a couple of days later. I checked through the inventory first and boxed it back up until I was ready. I spread the construction over a few days,

Not really. ?The JS8 encoding was changed in several ways such that an FT8 decoder can't decode it at all. ?And AFAIK currently the modifications aren't all documented sufficient to allow

No CW.? But plenty of S7-S9 FT8 sigs up areound 10.136.? Sigh.

I live in Colorado and routinely make contacts with my mini’s and QCX rigs on both coasts with a trap vertical. Unlike FT8 and such, you have to be patient and work at it. That’s ham radio. Gary

So far, same as prior on 30m.? Nothing heard, tossing a few cq's out in vain around 10.106 Mark K9TR

I enjoy FT4/8 modes, as those are the only modes I can use to make contacts.? I'd much prefer CW, but CW contacts, with low powder and what amounts to a faraday shielded antenna just don't yeild

Colin, I use WSPRWATCH for iPhone by Peter Marks, a free app. I brought up your Call and there are many spots, see the attached map. Looks like it’s working good. I can send you a station listing
