Ok, so maybe I'm the only one missing something here, but..I don't see any photos. And I always love seeing creative "casing" ideas.

I would expect you to, definitely. Are you using the QLG-1 gps board with the U3S? As I was building mine, modifying, and testing, with a single BS170 into a 50 ohm resistor as a quick and easy dummy

Without the lpf relay board plugged in, and even with the relay/diode now installed on the U3S board, I think you'll need the 2 jumpers in place to essentially bypass anything related to the relay swi

I had one fail in a similar way, clusters of extraneous pixels, just one day it started, no trauma to the display, etc. After checking for anything obvious, decided it wasn't worth any further effort

This thread definitely confirms why, I'm guessing, so many people just buy the pre-programmed chip from Hans and call it a day. I'm not a qcx owner, just a U3S and clock owner. I'm reasonably skilled

I use an arduino board as as programming socket, and a USBTiny from Adafruit to do exactly what you are suggesting. No reason the mkll wouldn't work the same way.

I echo the vote for Hakko. I have the analog predecessor to the 888D, and swear by it. I've used some of the cheaper import units, and while I see them as adequate, the Hakko's performance more than j

I got an alert about it when I happened to be logged into the usps site a few days ago. Packages from Hans are one of few where my delivery person has to have a signature, so sounds like I need to pla

Take a look at the U3S 3.12 operating manual, and you'll see that you can configure multiple bands (along with modes, etc), and run automatically. For a multi-band WSPR config, you'll just need the U3

1/4 watt 10 ohm resistor I had on hand, and about 5 turns of scrap wire from another QRP-Labs build, wrapped around a T37 core. Did not even measure the choke to see how close I got to 27 nH, to be ho

An Arduino board and AVRdudess is my go-to for updating 328s; I can relate to your bad wire issue...I spent a couple hours a few weeks ago chasing an issue that turned out to be a certain someone havi

Happy Birthday! Great to hear you got it. I will tell you while I was able to sort out the multiple band configuration fairly easily, I spent a ton of hours chasing a low power output issue until i re

In the midst of digging into this I did find a newer library on github than was linked to; didn't spend much time comparing differences. I ended up using that one once I found it. I stll need to take

Hopefully you didn't mind me jumping in and helping out, it was a fun little diversion for the day. Apologies for blatantly hijacking your thread. The "software serial parsing" example is the framewor

Page 4 of the manual lays it out for you. There is an "index" which tracks each of your entries, then just match LPF board relay number to correct freq and you're good to go. You can then enable or di

Its now working. Not totally clear on why it is, but I know what it is. The parse statements and method he used to read the data sream doesn't seem to work with the two gps boards I have. After insert

Jim..did you post this in the wrong thread?

@Don Degregori I now see what you mean re the use of "fix" and how it affects the data being printed, but that is not the core issue. The gentleman's code is basically a clone/copy of one of the adafr

The issue is *not* the adafruit libraries, its the supporting code itself. I went back and tried a few of the examples provided within the Adafruit library package, and they worked fine, including one

Hans...I think my fragmented message created some confusion. I did try the adafruit library with both modules. Here are the steps I took that suggests to me the Adafruit library is, in some way, where
