If someone is into making boards, I'd buy one.? Not real crazy about the AGC board offered by InKits.? Etching a board is beyond my capabilities now a days. David, K6DMA

Jerry Sounds like a good reason to save the pre-processor output and name it *filename*.ino This way you only need the libraries once and can dispense with the #include <*library*.h> stuff for future

Thanks for the tip Howard. I have some spare IRF530s no 520s but I will keep that in mind. The kit has not arrived yet so I will finish the Bitx first. But for that price I could not resist buying one

One problem with libraries is that they change. Sometimes stuff simply disappears off web.? Good luck building the original Bitx40 code of Dec 2016 (the etherkit si5351 library has changed). A good

Reason at Microsoft has always been focused on how to make more money. Nothing else. That's how they got so big. There probably are plenty of people at Microsoft who like github and want to see it

Thanks to all of you that responded, it's good to know that I should be able to work on the SMD components if required.

So how do we beginners determine which libraries are missing and where to find them? I would start by urging programmers to follow the convention I mentioned earlier, which is to provide the download

Thanks Skip. I'll certainly try that before I think about removing R70... Do you think it's worth building the rest of the audio path as per Version 4?

If the mixers are getting hit hard enough to go into compression,? then we don't really need 12dB of gain in that transmit side 45mhz amp. May as well back it off to 8 or 6 dB, 0 dB is fine, whatever

Hi Dennis, It looks like what you are trying to compile is, the code you would see if you clicked on "view source code" in your browser while looking at the code on GitHub. Of course, it is possible

I went ahead and made the mod as suggested by Allard to improve the CW Carrier Waveform shape on the BITX40.?? The 2.2uF capacitor value to ground wasn't correct (I think Allard based this value on

Too bad the Arduino IDE doesn't have a GUI interface to 'upload' a .hex (or .elf) file. ? ? This would make it easy to share a single 'compiled file'/ machine code and you could just upload to the

How about sweeping a 2-3 xtal filter using 40- or 48MHz xtals... In all possibility they will be 3rd OT. Rahul VU3WJM

Exactly. I have both the bit40 and uBitX and as far as I can tell the difference is firmware and means of connecting to the main board. In the uBitX the firmware uses an encoder to change the vfo and

You may check www.rf-microwave . com. They sell to universities, labs and hams. I bought quite nice stuff from them. Maybe they are not the cheapest but they have them... The owner I was told is or

I use 2 soldering irons to remove double ended SMD components (kind of like tweezers). I often use this method over a hot air reflow station, which I also have, but prefer the low(er) heat approach.

So how do we beginners determine which libraries are missing and where to find them? I'm going to try this exercise on a win10 machine later today. Perhaps it will work better than the mac. I don't

It may.? I've considered a compressor with peak clipper for the audio to hold the level below the distortion point.? Then I looked at why we get distortion (spurs). I'd still do the audio processing

To Robbie and all that are when I installed the pop fix I connected it to M1 side of C51 which works. At this connection point it will not short out the audio to U1 and your side tone will work. The

Thanks Doug! And thank you for notifying me of the bad link. I still haven't figured out what went wrong so I deleted the link. Must be something stupid simple (my downfall!). Don
