Hi Guys, When sending cw in the straight key mode with my bug, the very first dit or dah is delayed. Is there a simple fix for this? I have searched the messages but have not found a clear, simple fix

Seems I have often read about people longing for a bit more RAM for the Arduino. I ran across this and thought it might help some folks out. Probably a lot of people have a bunch of old SIMMS in a box

21 MHz is now open almost all the time. Here is what turned up on the sbitx this evening, just before dinner. Please note the decodes are within the sbitx screen.

Pete and others who requested the circuit, here it is: 1. The circuit is still to evolve into a CW/SSB transceiver, at present it is only SSB. 2. The relay used to switch the crystal and low-pass filt

Hello everyone! Today I played a little with my Ubitx, I made a lot of contacts all over Europe. After a while I decided to listen myself on a SDR located somewhere in Norway because I wanted to play

anyone used or thought of using a raspberry pi pico in the raduino? I still think that the teensy line is a great option, but they are a little pricey. Nanos are only cheap if you get them from China

Hi all, Sorry the off-topic. You all probably already know ADX, but just in case: https://antrak.org.tr/blog/adx-arduino-digital-transceiver/ It is very simple, but seems cool for digital modes using

Last weekend, the IARU R1 50 MHz contest took place and I thought it was a nice moment to show the performance of my 6 mtr transceiver as well as the activity. I made a small video about this: https:/

I have a new, assembled uBitx V6 available. I received it new in January and out of box, I could not get it to work well in CW mode, which was my intended use, and the mic was inop, replaced by HF Sig

Sorry for being out of touch. So I apologize if my questions are somewhere else on the forum. I currently have a version 4 and am having some issues with it beyond harmonics and spurs. So I am thinkin

I recently finished up my version 5 and lo and behold to my surprise, I have no display. I have checked all the wiring over twice and cannot find any errors. Has anyone run into this problem. All othe

hello group, Is ND6T's version of the AGC/S meter considered the most viable for V4 ubit x And how would I hook up a sig-gen and scope to test it KM4TRT

I want to experiment with FT8 on my µBITX, so have built the simple interface using a USB sound card from my Mac + WSJT-X from G4ILO's website (schematic attached below). I could do with some pointers

I've had and enjoyed a somewhat modified v4 uBitx for years. Last week we had some area thunderstorms...nothing nearby, but I suspect static buildup on the antenna has zapped my rig. It still receives

My Mobile Ubitx use thoughts: Suggest adding a tuner-spinner lock out switch. Add a separate tuner-spinner activation push button. You may want to change the Ubitx default tuner-spinner to a detent-sp

I just renewed bitxmap.com for another year. The map has been up for about 4-1/2 years and with its own domain name for 4. We have 784 points mapped and close to 62k views. While this is not about mon
