Guys,?

This is a hobby. ?Whatever brings satisfaction to your head and a warm glow to your heart (and lowers your blood pressure and helps you tolerate all the rest of the world) when you walk out of your shack is fine and OK in my book. ?Maybe for me it¡¯s just breathing in rosin core solder smoke that does it.

its something i wouldnt install in my ubitx v6 but to each their own.probably has a decoder for those who like to send way faster than they can copy cw.HI HI.
Im a purist. decoders for cw are an insult to the cw community as a whole if you operate cw.this is from their website:K3NG¡¯s arduino code, such as LCD display, USB keyboard, rotary encoder and CW decoder etc.

looks nice for shortwave listeners who like to tune in those secret signals, but just my opinion,? my decoder is my ears. you always know someone is using a decoder when there is a little bit of adjacent noise and the decoder cant tune it in. even though your signals and theirs are 599.

decoders for those who try to appear to copy way way faster than they are able to.sometimes they use the programmable keyrs to make canned contacts too.Sometimes "SOME" those who use decoders? are the ones who apply for fast code decoding awards from the ARRL w1aw bulletins.

Your friend is happy with his ability to make thousands of contacts mechanically. I think that trying to improve him and his ability would be a waste of time. If a hobby is doing what a hobby is supposed to do for a person just leave them alone. ?I have a few friends that use their CW decoders all the time and they are happy collecting countries and wall paper¡­.. they just do it differently than I do. ?I found the same with RC airplanes¡­.. some buy their planes already built and others build and repair their planes themselves¡­. They both were happy with their hobby.

Reminds me of RTTY. ?Let the machines do it all. ?To each his own. ?I left FT8 because it just made contacts, not true conversations.?

David, this is really, really sad.

Subject:Re: [BITX20] Funtronics uBitx digi interface installation in V6

last point of my opinion, and i apologize if i come across as a hater,but im not.

Friend of mine is a no code ham. he learned the basics of the code and uses a decoder to decode the cw. he sends about 20 wpm with his paddle ,which doesnt make sense because he cant copy past 6 wpm with his ears. i proved this with on air copy. doing about 8 to 10 wpm. he said he couldnt copy it even though he sends really fast. he doesnt try to decode the cw in his head since the decoder is doing it for him. I told him if you can send 20wpm you should be able to receive faster than 8. no way. i had 3 other hams verify this. WEIRD,BUT TRUE.He stated"why learn to copy faster when i have my decoder. he uses software to do this on his not knocking him,but i did explain the reasonings of not using one.happy he is trying cw and using it,but the decoder gives him a false sense of accomplishment. he has been using this setup for several years and still cant copy faster than about 6 wpm. WEIRD ISNT IT. My friend is an engineer for 30 years, very very smart, but has been ruined by his decoder. HI HI.3 of us have been working with him with various,various methods, and we even paid for his classes,etc just to be friendly. he went,but the instructor stated "ive never seen anyone who can send 20wpm and not copy by ear at least over 6 wpm. He refuses to try to fill his head with the decode but can send 20 wpm with his paddle. foud out some of his secret. he uses precanned groups of statements. qth,radio,rst,etc. He goes thro the motions and then after his decoder decodes the other hams info he clicks the statements he wants sent next,it also includes the 73,etc. .very canned,very brief, using decoder and software on computer.? is he running cw? yes,but with an analog radio and no goodies attached to it,like a decoder,he is dead in the water without it.Ive praised him over and over for trying CW,but He stated "i can make 1000s of cw contacts and basically not even know CW"The computer and decoder will do it all for me.His words,not so his paddle is basically for looks. he uses computer control to do the sending 99% of the time.

please inform the other end u are using one if you cant decode the signals when adjacent qrn,qrm,qsb affects it or you are in a is leads to abrupt endings of qsos. or qsos that really seem robot operated.I ran into this when doing ft8. Someone calling cq forever and not responding to others who respond to their CQ.

just my own opinion of it.

Shielding is not the issue. Losses are. Lower Q leads to higher losses. The Q is determined by the material inside the toroid. Air/Vacuum is the best material with least losses for an inductor, whether a solenoid or a toroid.

I've enabled SSH so that I can remotely log into my radio from a laptop and do things from the command line, while sitting on my sofa in another room watching the news.

The sBitx should really appeal to those who are comfortable with computers, and like to experiment with software vs solder and wire. This radio has really been a blast - and is also a great way to learn more about DSP algorithms and linux in general.

Re: apt update/upgrade #sBitx

 

Mark,
Go ahead and do it. You have two safety nets.
First, the original sd cd image is on the gdrive link on (it is too large to be on github.
Second, you can make an SD card backup from the menu (I dont remember where exactly it is). Or you can use the venerable dd command (look up the usage on rpi forums).
Except for the config.txt, I don't see why apt update should change anything. Try both.
