Joe - check the PTT circuit and compare with the uBITX. This might fo the job nicely. Pete, N6QW, documented the tiny circuit very

Doug, I have a couple domains registered in my name already.. I can add bitxmap.com to the list if you dont get any takers. Chris N W6LXH

I created a Discord for sBITx. Great place to text chat, voice chat and share videos and pictures. Here is the link for invitation. It is a public chat. I can make private once we get people to join

Vic, It was the v5 code that transmitted a 10MHz signal.? The v4 still had the AM zero beating to calibrate it.? Regardless, Nick is using the KD8CEC firmware, which does not have the transmission

Nestor, The slides belong to QRPARCI, however, they haven a welcome policy to allow the presenters to publish their paper online. I will expedite this and publish it in a few days. I am still

On the V4 uBitX that is the way calibration works...it puts out a signal at 10mHz, as I recall, so you need to have it working into a dummy load and adjust i while listening on a separate receiver or

Good day to all Just a question as the daylight again the slides for bitx 23 are available? I really want to know the design process Thanks

Hi Yvon, The linked message from Gary Anderson pointed to a possible solution to your issue.? Here is the message content: Begin

You mentioned you tried several Pc's. Normally I would suggest re rooting and making really sure nothing is using that Com Port. Win versions tend to hang onto Com Ports. Triple check. Swap cables as

Hello, I bought a used uBitx v6 that is off frequency by 3KHz on 20m and 1.5KHz on 40m and so on. I did download and compile the latest version but was unable to upload it to the Nano. I am

Hmmm.? ?I've never tried it with Linux, so I don't have any particular insight there. The only other things I can think to check are on the tools menu of the Arduino IDE, that the Board is set to

Rolan, The code seems to be good in both places I am using Linux, not Windows, if that will cause any problems. Bill

Hi scttmtclf; The sBitx DE does not have Power / SWR detection circuitry. It is not difficult to add this circuitry to the DE, and several people have already done this successfully. Look at the

Have you installed an SWP/Power sensor?? That was not included in the sBitx DE V1 radio.? You would need to build/buy a Stockton bridge and an ATTiny85 and wire them in.? Ashhar Farhan did say

In the file tab "ubitx_v6.1_code" in the Arduino IDE, there should be a line about a quarter of the way down from the top of the file that looks like this: bool isUsbVfoA = false, isUsbVfoB =

Last chance for someone to step up.? After keeping this going for close to 6 years I have decided someone else can have a turn.? All the details are in /g/BITX20/message/102225 The

So On my sbix DE v1, i upgraded to the latest software version with a fresh sd card.? I am trying to calibrate the power output, and I am running into two issues.? The first is that with the drive
