Those that missed out on the previous posts of this epic thread might look over this one:? ??/g/BITX20/message/55641 My conclusion (opinions vary): With careful design and perhaps

I had exactly the same issue on a raduino signal generator project...using a cheap encoder with detents.

It works fine in Linux for me. -- 72 and God bless KD4EPG

The stock encoder doesn’t have detents. Try one without the detents.? -- 72 and God bless KD4EPG

Thanks Gordon Exactly what I was looking for, and validates my circuit and calculations.

Made some progress on this. The board is now alive. The LCD and encoder sections are functioning. Testing the Si5351 is next, then see if I can convert uBitX20 firmware to run on it. www.w3jdr.com (

These days what changes is the number of qsos you can do with a qrp and an ordinary 100watts trx. With a better propagation this 'spread' would be much reduced.

I didn't realize that the band is good enough these days to go that low.

I'm expecting to be able to make real baseline measurements tonight.? ?My receiver (Icom 718) cannot really go past 30 Mhz so I'm restricted to measuring harmonics' strengths below that

Since several asked if the Raduino "Clone" board kit available through the "Triumvirate Skonk Worx" (www.w0eb.com) would work with the BITX40, I did a little research and the answer is YES it will.?

99% CW on my uBITX.? I have the click and AGC boards installed along with a Hi-Per-Mite outboard filter. Works great. 73, Bill NZ0T

I put in a pull request to fix this 4 days ago.? Linux uses a case-sensitive filesystem so you need to change the case.? The case is already correct in ubitx.h.? It is incorrect

Tom, A L network L first is a low pass.? However most are run at such low loaded Q they are not very useful for harmonic control.? Typical Q is under 10 and 2 is not uncommon. Allison

Brent, Yes, QST September 1988, bandpass filters. For 15, 12 and 10. Allison

Yes, the tune able preselector idea is what I was thinking. I believe I have all the parts in my junk box. Also, has anyone here built a tap to sample signals from a dummy load? I don't have a

hi works perfectly in windows but linux is proving a bit difficult terry gm4dso

Referring to the parallel resonant transformer (especially the excellent description by Chuck N1KGY), if I wanted to put the capacitor on the low impedance side instead of the high side, let's say at
