Just like I said in my previous post several days ago. Amen Alan.

Most meters of this type are useless, especially at low capacitances. Even a dedicated capacitance meter should be viewed with suspicion unless you have checked the calibration. (Unless it is of

Don't have a QCX, haven't tried it. But I'd consider feeding 12v into Q6 (and thus the BS170's) straight from the battery, leave everything else to run from the protection diode.

I understand. I choose to bypass it if I'm going hiking...

For me the protection the diode offers far outweighs the slight received signal improvement ( not measured power out) you get from bypassing it.

Like others have mentioned, you may want to check capacitance at RF... if you can't do that, I'm sure there are several hams in the Knoxville area that would love to help you out. I followed

I tried to be pretty meticulous when building it. I definitely had one spare cap in addition to the others for different bands and the kit was actually short two of the 10uF electrolytic caps that are

Isn't the OSX an Apple product? The QSX does not use either an Arduino or a bare ATMega. It uses an ARM microcontroller. The ATMega would be far too slow for the DSP computations done in the QSX.

Hi Al QSX will use commands that are compatible with the Kenwood TS-480 protocol. So it will work immediately in all software that uses CAT control, without delays. 73 Hans G0UPL http://qrp-labs.com

After fiddling with a different radio / computer combination , it dawned on me that I've not heard nor read anything about ( or at least don't recall ) computer rig control. Here's what I am wondering

Gerry: Not sure you're addressing me and my Morse Code Trainer (MCT), but I'll assume you are. The microcontroller used for the project is an STM32F103. It has 128K of flash memory, 20K of SRAM (the

Looking forward to it. I hope to have the pipeline cleared by then - unless Hans releases the OSX. Is it running on an Arduino or a bare Atmel micro? / Gerry

Seems a tad expensive... Jack, W8TEE

I believe there were not supposed to be 'spares', but parts for other bands. Was the loose one you tested actually marked as a 390 pF cap? What did you measure it with? I presume what you stuck in c25

Way to go, Dave!? Your many studies, experiments, engineering, and skill have generated quite an achievement!? I missed it this time around because I was fussing around with the next version of my

This looks a bit like the Morserino, which I'm also excited about: http://www.morserino.info/morserino-32.html 73 de AC3K

Just to be on the safe side, I ordered new silver mica's for C25 thru 28 to go in my QCX 20 if it ever gets here.? 73 Jack KZ5A

Did you check the markings on the caps fitted. Component quality is very good these days. Did you check your tester against a known good capacitor. What are you using to test capacitors, is it a DVM

Hi, I am happy to bring my equipment back to FDIM again this year and set up in case folks want help with surface mount component soldering or other soldering tasks. If so please let me know. There is
