Re: Ideas for AM, NB FM Demod and CW filter board
Hi,? Yes I think this would be a great improvement to implement also AM/FM to the uBITX.? Does anyone have some ideas ? Thanks !

Re: Raduino replacement #bitx20
According to the website, the only difference in the Raduino¡¯s is the firmware. Are you saying this is not the case?

I have a little more than 0.6v across base and emitter on all of them. 7.7v across collector and earth on Q10 and Q30 and 11.9v on the rest. Seems ok. I have only unsoldered and ckecked one trifilar

Re: RF power chain mods and improvements..
Ok. To attenuate spurs at an acceptable level we might add a high pass filter for the 10m band. However for the 15 and 12m band I don't see an easy solution

Re: micro bitx: strong signals from broadcasting stations
That can be removed with a high pass filter especially if you don't mind for the 160meters band. It can be done with three small toroids and high voltage ceramic capacitors. Just put externally. You

Re: Github's future?
Fortunately, the way git (the software used by github) is structured, it doesn't really need a server! git is a distributed source control system. that said, it does have server mode that can quickly

Re: The new uBITX boards are here
Jamie, Check on ebay for old GE and Motorola communication speakers. I found several of $6. You can either use them as an external speaker or pull the speaker out and mount it inside your case. The

Re: RF power chain mods and improvements..
Arv, This is how I've always operated my linear amplifiers. Tune for max in CW and then mark that level on the oscilloscope. When in SSB never go above that level with your modulation. It's a pretty

Corporations are not evil, they're indifferent. That makes them quite dangerous indeed. Microsoft hasn't changed all that much from their adopted philosophy of "embrace, extend and extinguish" since

Re: #ubitx-help #ubitx-help
You have to have 12V in the RX biDi amps Hakan. Q10,11,12 and 30,31,32 must have 12v on rx, if not I suspect the relay K1, please check! Raj

Re: Bitx 40 source file
Hex files scare me. Nope just unpacked fhe zip file and tried to open the .ino file like I did before.

Re: Bitx 40 source file
Did you upload a hex file or actually compile the source code? There's a big difference. Jack, W8TEE

You mean the Arduino application? its in the Applications folder of MacOS 10.13.5 I can upload basic sketch into the Nano. Further I used this same Application to upload the kd8cec into an other Nano

Re: Github's future?
I certainly would not change from Git. It is a standard that is not tied to GitHub. I also have an account on BitBucket?https://bitbucket.org/product?BitBucket and GitHub both have free accounts.

Where is your IDE installed? I see a libraries directory right above the sketch directory, but I don't see all of the other files that should be in the compiler directory. I think your installation of

Not really. Read the popup carefully.? It names the INO file raduino_diag_v3.ino and also names the directory holding that file raduino_diag_v3. As I said before, the directory and the INO file MUST
