Thank you for your reply..
What is difference between dynamic mic and electret condenser mic? Do they look a like in shape? The one I bought is look like this ..

Re: Mic doesn't work in bitx40
#bitx40
Thank you for your reply,?
I build my own bitx and bought all the component by myself.. The mic element was an electret condenser mic. I wired it up according to the datasheet..
Maybe there was something wrong with the wiring. But all the connections are good and the schematic are exactly the same with the schematic in bitx40..

Re: share your BITX success stories
I've given my report before, but I'll throw it in here for giggles.
My uBITX is my first HF rig.? I ordered to close the deal on getting my Extra.? I got my Extra 2 weeks later and got my CW up to 13wpm (5 char, random) as penance for not getting my ticket 30 years ago.
While waiting for my uBITX to arrived I read every...single...post, looked up part numbers, googled what it did when I didn't understand it, ordered some extras, practiced my soldering and read some more.? I ordered the SMD practice boards, a new soldering iron and some spare IRF510's and RD16's as well as some SMD kits.
uBITX arrived, I soldered it up and started the "Junkyard Dogs" thread here for my complete lack of regard for aesthetics.? I fired it up and couldn't get any SSB QSO's with my EFHW, so I found the CW key memory and sent "TEST AG5OV TEST" a few times and checked the RBNs....IT LIVED, I was getting out!
Next I updated the firmware to Ian's fantastic work and soldered up a home grown EasyDigi interface and plugged it into a RPi.? I've been running FT8 and WSPR almost continuously since I turned it on a couple months ago.? I'm over 700 digital QSOs, 0 SSB (it'll come, no rush) and 0 CW (printed up a key, just need to wire it up).? It's been, simply, fantastic.? I'm so very glad I went with the uBITX as my first HF rig, the experience with both the product and the support here has been more than I could have imagined.? It's what I got into ham for, to explore, to learn, to discover to get that spark in the mind of "ah ha!".
I wouldn't change a thing, even my dreaded WX2822...where I got to down convert to 12.1v instead of running at full 13.8.? If I had wanted to make eleventy-seven DX SSB QSO's in the first week then I wouldn't have picked the uBITX.? I don't need that, I yearn for discovery and and exploration.
I'll add that I have a 2nd uBITX still in box that I need to wire up and put across town.? I'm super interested in not just digital modes, but data modes and having my own testbed with rigs across town and network access to each end will be great fun.

Roxi,
I totally agree with u. some members spout a plethora of knowledge but won't respond to any ham asking for help. but shame on any of us who love to build mention the bickering about who's software is the best what standards etc. Thats why some clubs shut the doors because of internal bickering and everyone has to do it their way.im a builder and a qrper. i bought this rig for the economics of an all band rig and possibly modify it MY way later with the help of other great knowledgeble hams on this forum. I mean really, price of other rigs, and they are outrageous.
Farhan has an incredible rig. unfortunately some hams aren't happy with anything.ive been a ham since early 80s, and i love cw. some do not. some refuse to be my friend anymore because i love cw. oh well, its a great hobby. and a lot of hams forget that. i don't get impressed by the bickering and arguing. its boring and stifles amateur radio as a whole.i was lucky to have mentors who really enjoyed ham radio and was OPEN i repeat OPEN to others suggestions without arguing.i love the forum and the knowledge others bring to share or help ,but i erase any posts that have a bickering title to it.they forget there are thousands of hams who have gone it alone because of bickering ,only to discover a new technology.there are also thousands of hams who are programmers and they don't get on here to argue about code. life is too short to bicker about petty things. Well roxi i probably made some mad but, they will get over it. if not they don't need to be in this hobby. remember we love this hobby to promote technology , self learning and spread goodwill across the world without any biases or politician agendas¡?
thats why i mostly work cw. try arguing in cw .:)
73s David? ka9koj.
p.s.?
remember to have fun.

Indeed
I have always said folks need to be more appreciative of what they are
getting here and less ready to bicker/moan about stuff.
Its an awesome little radio and provides freedom for those who want it
and simple function for those who just want it to work.
This group of folks is awesome and will help with any issues so is
pretty much the best of both worlds.
Thank you again Mr Fahran

Re: share your BITX success stories
The uBITx has been a blast!? 330 FT8 QSOs in 6 weeks including 46 states and 12 countries on 4 watts or less.? Using end-fed 59 ft antenna to tree.? Having too much fun to see the negative......:) Looking forward to "souping up" the 2nd uBITx!

Re: share your BITX success stories
I haven't had a chance transmit other than CW mode into a dummy load. I want to finish my antenna analyzer before I start pumping rf into my Carolina Windom. Reception was very good but noisy with all the weather here in Florida at this time. Lightning is a major concern as my antenna is almost as high as my natural lightning rods, pine trees 60 - 90 feet tall. As a QCWA member I enjoy CW as my primary mode but really have enjoyed WSPR with my U3S. I see alot of digital in my future. 73 Bill WA8VIH/4

Re: Newbie instructions for loading software in Raduino
#firmware
The Raduino is a combination of two things.? The chip and circuit that generates the frequencies, and a Arduino Nano.? You can unpower the uBITX and plug the mini USB plug into the Arduino nano unit on the Raduino board to power it up and program it.? In other words, forget about it being a Raduino board and just think of it as the Arduino.? Look around on Youtube for lots of info on programming the Arduino nano.
I actually blew the nano board on my ubitx and replaced the nano board with one of them off ebay that sells for about $ 3.? You can get one of those and play with the software so you will not mess up the one in the ubitx.? I have just gotten into playing with the Arduino in the last 6 months or so.??
The kd8cec program and his memory manager is very nice.? ?I modified mine to use the 6 push buttons to make it more convenient to operate.?

Just a couple of days left in our "Name the Board" contest.
About three dozen entries in hand.
Entries due by 2359 UTC on May 20 2018
Only entries sent to "jrg.qrv (at) gmail (dot) com" will be considered.
Information about the new board and the contest can be found at <>
Prototypes are due in three or four days. But here's an attached image with just a "teensy" peek at the feline hiding in the sack....
Our working name was "RadI2Ceensy" [ RAD eee too SEEN see] but that's a bit like branding your jams and jellies "Smuckers" and hoping folks will like them LOL
Good Luck...

I want to make a substitute Raduino using a "Blue Pill" STM32F103 board. Does anyone know where I can get a quick start on the CAD by finding an Eagle or KiCAD file set that already has the critical connector dimensions on it?

Are you using an electret condenser mic ?
If you connect a dynamic mic then what you describe is correct. The design is for electrets.
