I ordered far too many of the 1K/3W resistors for this project.? I've enough of the passive components plus D1(BAV21) for four additional builds.? ?I've made up four kits consisting of 20 1K/3W, 1

Moving the BFO to the other side of the 12mhz crystal filter can make a difference, as the skirts of the filter are shaped differently. Also, moving the VFO to the high side (on the Bitx40) or clk1 to

Ty, make sure semiQSK is ON in the SETTINGS menu. If the radio is in LSB mode, it will switch to CW automatically as soon as you push the CW key. (if it's in USB it will switch to CWU). Press PTT to

Ty CW always uses the USB mode. Until I recently upgraded my uBitx software I had never seen a LSB CW mode. Why that was implemented I don't know. Don't bother about it no-one should ever use it.

Hi all, I've had my bitx40 working for a few weeks and now have implemented the??amunters / bitx40? goodies. Thank you developers and testers! I was surprised that nothing happened with I pushed

Hi Dave, Obviously unattended operation is allowed where you live and are licensed. Some of that is allowed where I live too but the problem you have outlined is the main reason I don't do unattended

Get a smart outlet (something that you can control with Echo for example) and shut the outlet off if you have a problem Kevin K5KDT wrote:

Hi, I use an old laptop for FT8 with my uBitx and works perfect (CAT via USB). But sometimes my computer hangs (BSOD) and, when the uBitx is in Tx, the radio keep transmitting. I use this computer via

Labtec makes a good computer mic that does a good job on the ubitx. I have 2 of them. Also, I had a avalier mic that I bought sometime back from China for $1.99. It works good though not quite the

This is the same method used in the Ten Tec Rebel. The Rebel circuit also uses voltage controlled coupling at the ends of the ladder filter.? It provides 3 distinct and surprisingly effective

I clamp a short length of angle iron along the line of the opening, and file to that. Gives nice straight line. Rectangular chassis punches are available but are verra costly, and the larger ones
