It's not terminal. Just run a jumper to wherever it supposed to go next.

I think you're looking for this: http://qrp-labs.com/qcxp It's an updated form factor of the QCX.

My own trick is to add *more* solder to the joint so that it stays molten longer while I give it a whack on the bench. Works great :)

Oh yes, been there! https://miscdotgeek.com/genuine-irf510/ It was not fun! Lots of blown counterfeits for sure.

Hans sold almost 10,000 units without an audio amplifier for directly driving a speaker. If you want to add one, spend two bucks and as one. https://m.banggood.com/LM386-Audio-Amplifier-Module-200-Tim

Okay, I just got the mod completed. Wow. Wow. Wow. I am actually seeing *more* than 5W output if I crank it up. I wonder what those BS170's can handle? ;-) Thanks for posting this, Manuel (and Guido,

Great, I'll revise my build this weekend 😁

Since Hans is swamped with email already, I'll take a stab: The QCX+ is the new version of the QCX. The old version is no longer available. It's 13x10cm vs the old QCX 8x10cm foot print. That's 5cm la

AAAaaaand, just got my first contact by checking into the Noontime Net on 7283.50! Audio was reported as good. Gotta really shout into the mic to get 3-4 watts. Any suggestions on making that a little

Hi Manuel, I'm glad you liked my capacitor toboggan! I showed a coworker your comment, and he made this: Unfortunately, right after the next turn, the toboggan crashed into a solder drift: Don't worry

Spent a couple of minutes before work coming up with a solution. No 220nf capacitors were found last night, and so I decided to simply make one. I used leftovers from the kit, two 10nf and two 100nf c

My previous post got me thinking: It's in the microphone section. So I went to the schematic. R58 is now a 220nf capacitor. So I look at my capacitor. 221. Wait... 221... I think... oh my god. It's a

Hello all, I do have some progress to report! After rooting around the code, I found the "Force SSB/SDR" line and uncommented it: ssb_cap = 1; dsp_cap = 2; // force SSB and SDR capability Now I'm gett

Fair enough :) Ryan Flowers

Why make a PCB? I think the fun of it is that it's a hack! If it gets its own PCB, then it's not a hack, it's a new product. And if you're going to go to the trouble of doing a new PCB, you may as wel

Guido, thank you for the compliment and guidance. The case is from my original BITX40 build: https://miscdotgeek.com/bitx40-case-build-w7rlf/ I put a lot of work into it back then, and learned a lot.

Well, it receives what seems to be okay, but there's no sideband rejection. And, the microphone is fine. This all seems to point to a construction problem on my part, it seems. Perhaps I need to go th

I completed assembly in a temporary enclosure and fired it up. It seems to receive fine although I have not had a chance to mess with it very much. I tried transmitting in CW mode and it put out full

I haven't gotten far enough to test transmit or receive yet. I still need to wire up a speaker and a low-pass filter and then connect an antenna to it. I'm actually working on that right now :-)
