Re: VK2AUJ's ?BITX project
I am going to FDIM and Dayton. ?I have read many posts about temperature of some chips. ?Does anyone have a suggestion as to a reasonably priced digital temperature gauge? ?I see the Harbor Freight has theirs on sale for $17.00 USD. I know that is cheap and probably not accurate enough to be useable. ?Any suggestions?
This is my Dayton list so far:
1) solder sucker 2) digital temperature gauge
Also, does anyone know if the "Maker Bar" in downtown Dayton is still in business. ?Two years ago it was written up in CQ and I visited it. ?It was a great place to hang out, build something, have a brew and make new friends. ?That night all the instructors were very nice ladies...... Another draw for the young "Maker" guys. ?When I talked to the manager he had hopes of franchising this idea to other large cities. ?They sold kits, had a dozen or so soldering stations with air cleaners, high intensity lights, vices and 3 different types of 3D printers, and instructors who did not charge for their assistance. ?Newbies welcome. ?They even gave away little skeleton head pin kits with eyes that would blink and change colors. ?What a hoot.

Re: BITX20 at Dayton Hamvention?
Re your dog: ?I listened to NPR yesterday on the subject of loneliness. ?It affects a persons health the same as smoking 15 cigarettes a day and is now considered a major health risk. ?Having a pet greatly reduces the risk of early death. ?Love your dog. ?I am a retired family doctor and I saw the effects of loneliness on my patients, not just the elderly ones. Our young people are the most connected of any generation but are the loneliest they have ever been.
My wife has been away for 3 weeks helping my kids in a move. ?Our 15 y/o diabetic cat has been a blessing in addition to a few ham radio friends and my church.
Again, love your dog.

Hello,?
I wonder if anybody could help me with following questions. I have ordered uBitX and would like to ready to go once I get it set up.?
1) I assume audio in and audio out jacks are 3.5 mm. Are they mono or stereo, two or three conductor?
2) Can I use audio out to connect to PC mic in? How are you doing digital modes?
3) Power jack size, 2.1 mm, 2.5 mm? Assuming center positive as usual.
I appreciate all inputs on these, thank you!

Yes the inductor is 33uh and the capacitors are 220pf. I also added them to the first driver stage to. I measured before and after the mod and the drive levels just about doubled on all bands.?

Re: Calibration - my approach
#ubitx
Thank you Arv,?
I just happened to read your post at 43 minutes past the hour and it seems to have worked well.? I ended up adjusting my radio +17 from my initial setting.? ?
Immediately after calibrating against WWV with the radio menu, something odd with the BFO calibration setting did happen though; the BFO also changed (it was up around 11999 and I think it took effect when I pressed PTT to confirm the new calibration setting).
After realizing that the radio's BFO calibration menu would take me forever to wind back to 11997, I connected uBITX_Manager as I could just type in the number and then write to the radio.? However - as soon as uBITX_Manager connected, it seems to have reset the radio and the BFO value reverted to 11997.? ?
So I additionally suggest to immediately following your WWV frequency calibration with a radio power cycle before checking the BFO Calibration setting.? If anyone else can confirm this behavior, perhaps we can flag it for Ian.?
Finally, tonight there was some Olivia or other MFSK traffic that was very audible on LSB at 7074.? So for those doing the calibration using the "by ear digital signal" technique I summarized above, be sure that you're listening for the 15 second interval FT-8 transmissions and not the arbitrary length MFSK modes.??

I bought your book. I have been promoting it when people ask questions about arduino's. You went to the trouble of printing a book that most anyone should be able to understand and even given homework for the reader to become more proficient.Barry Kauler, the author of Puppy Linux, used to be a assembly language programmer and taught University level programming in assembly. Even though it was difficult to find I purchased one of his early programming books. I am still learning assembly. My only rush in learning the race between saneness and insanity.

No one has the right to give away free copies of my book, and this outfit is no exception. Sadly, closing this site would have no impact as there are hundreds of similar sites that allow illegal downloading of my (and others') books. My solution is, I think, a fair one. If you download the book and find it useful, then buy the book. That removes the risk from your purchase, but rewards the writer, too. The real cost of pirating is probably not the revenues lost by the author and publisher, but the thwarting of future writing and publishing since there is no reward to those who expend the effort to write and publish the book.

Are they errors or warnings? There are so many people using the code that it seems unlikely that there are errors. I know there should be some warnings, especially if you have renamed most of the *.ino files to *.cpp files because of type checking. Still, the most likely cause is in the installation of the libraries. It would be helpful to see a list of the errors and the URL where you downloaded the source code files. Also, which version number and op system.
