I to all, I'm Valerio, iu5hkj. For a mistake, I've connected one of the orange wire that came from the Arduino Nano to the power supply, so Arduino dont't never works.

guys... According to DHL, my bitx40 won't be here for a week or so. So, I'm playing the ardunio IDE. downloaded the file BDOSoftwareRe10106. Have the right files in the libraries. Although I don't ha

Going like a herd of turtles, but made a little progress during lunch today, and this afternoon. Building up the chassis, measuring for the raduino, and punching a few holes has been the order of the

Hi all I have made up and installed version5, now all I hear is the relay clicks. Photo of board attached. Ted ZL1BQA

For those who are tired of the pop and noise when starting to transmit, I would like to recommend the simple circuit described here: https://groups.io/g/BITX20/message/21876 It eliminates the hearing

I have a Hendrix kit built Bit-x 20 (assembled myself) and after about a year of playing with it, finally started making contacts. It has the 10K pot mod instead of a tuning cap. and tunes from 3.152

None BiTX, but hope it is of interest to others if it hasn’t been mentioned elsewhere. QRP Labs are in the process of kitting up a new Mono Band 5W CW Kit for the HAM Bands. A great feature for those

Hi all, I have not been around on this board for a few months (got distracted by a 3D printer build and printing stuff). I have searchd the board but have not found the answers to the questions I have

Dear In my bitx40 during testing upto three qso power output about 7 watt .Then suddenly no output ,when i measure drain current of IRF 510 on mic disconnect conditions it was 90ma and with speaking

just received the VFO board from Jack W8TEE. All I can say is very nice board and can't wait for the parts to arrive. They say patience is a virtue.....I am not a very patient person.  Now I feel a li

Can someone please tell me how to install a "MENU button" on my bitx40. Does it need the latest sketch to work? Thanks in advance Larry

Hi All, I think most people can see Jack's and others email addresses OK on here ? It's not ' THE LIST ' obscuring the email address, it's peoples OWN browse

The program can't find MorseCode.h..... I set it up exactly as you have it in the manual..All the other non-standard libraries load fine. Does the file need to be under the Arduino directory ??? I've

When I went to pay for a BitX40 the shipping to the US ended up being more than the product. Is there any plans to find a distributor or at the least send a dozen of so boards to a customer that lives

I had to replace the LCD that came with the radio.  The new LCD has its contrast set too high.  Does anyone know how to change this?  Is it the blue and white pot next to the arduino?

I put together a VK3YE AGC, and it works. It seems to mellow out the audio a bit. However, loud signals are still getting through. I think that they are attenuated, but could use a bit more attenua

Hi, Just a few weeks ago I had my BITX40 set. First I wired it as basic trx. After some test I first added AGC it is a necessary option. It also takes away a lot of local QRM. After som more testing I
