Alan, I think this is what you are looking for. http://ubitx.net/2018/03/29/adding-a-tune-control-that-has-reduced-power-output/ Marco - KG5PRT [email protected]> wrote:

I agree. That would be an excellent fix, Pat. But it shouldn't be occurring. Alan, can you take voltage measurements of Q1? From ground to the base, and from ground to collector when transmitting? It

Hi mike, can you provide a schematic and parts list for power leveling relay fix? 73, Alan

Ambitious. Good luck with the development. I'll be watching with great interest. Thanks for sharing. Pete WK8S

Pat: That is a great idea! 73 Alan

What size beads? And where did you get them? How should they be installed?

Hi Don: When I unplug the AGC board with the audio and +5 volts still attached the feedback remains the same. When I separated the +5V and ground twisted pair and disconnected the ground feedback

I went down that same path and ended up picking off receive-only 12v from R52 and putting that through a VR circuit to get 5v for the agc. This way, you still have cw sidetone during transmit. Just

Someone made a request to order 2 of the jack break out strips I offer for sale via my website www.w0eb.com ( http://www.w0eb.com ) and my ISP (or my email client) deleted the message just as I was

These are great ideas. I saw another post where they used an old cutting board (plastic instead of wood). I'm just getting ready to do my builds (I have both r3 and r4 kits) here soon so these are all

About all we have right now is the attached feature set list. The assembly manual is probably a month away. We will be selling the PCB with all SMD's in place. Jack, W8TEE

Great minds... Jack, W8TEE

Thanks for the quick reply.? Where can can I read more about the JachAI project? Pete WK8S

Alan, when you unplug the AGC board, with the audio and +5 volts still attached, does the feedback remain the same? If so, what happens when you remove the +5 volts from the board (still unplugged)?

Well, I kinda?am an EE kind of guy, kinda, so I should probably fire myself for not thinking about it in the first place! It was easy enough to find a place for +12V on TX, namely pin 3 on U2.? I

I did almost the same with my Bitx40 except I used scrap PCB for front and back panels. Also flipped the board mount standoffs upside down, so a screw holds the standoff to the Bitx40 and the threaded

The K1 relay caused dismay here, so I replaced it with a small DPDT switch.? LEDs on the TX and RX lines provide a visual indication of transceiver mode.? I like this arrangement better than a PTT

Here's a breadboard technique that might help others.? When my uBITX transceiver kit arrived I had no ideas for a case, so I mounted the board on a piece of plywood and used 1/8-inch clear plastic as

It's brand new...never used it before, and it is part of the JackAl board software we're working on. However, almost anyone with just a modicum of programming experience and two encoders could

Just a suggestion,? but if you adjust the contrast control on the back of the display you can get rid of those dark rectangles and it will be easier to see. -- Lee - N9LO?"I Void Warranties"
