Hi! I remember a few weeks ago i read something about some problems with the AF amp and 13.8V power sources (shame on me, i can't find it again). It's safe to use a 13.8V source? I want to mount a

Hi Paul, I wanted something fairly small and quick hence no toroid winding, and looking through my SMD inductor box, found the ones shown. 1812 footprint. Nothing special. Similar parts available

Thanks Allison! I’ve seen these amps used on EBay and thought they could be repurposed. This sounds like a cheaper and easier alternative to scratch building a 100 watt amp.

Isn’t there a pot that controls the output power? If so you could make a low power switch that is just adding a resistor in parallel or series depending on the circuit. I’m just walking and

Joe, Terrific, I will adjust the code. Thanks, Vern

Hi, Glad its working 1. The save function is for the mem channels 2. In the code there are locations where you can enter your actual bfo1 reading Around lines 183-185 3. Also there is a location

Ah, too easy, I was hoping it was done via software and able to TX a much lower power carrier for tuning, not the full 15W... Any ideas and thoughts?

Brad, BINGO! Mike N6CMY

Richie, Its not so much what they use but how they use them. I have a Silconix 100W SS (literally CB) amp. Got it cheap for modding. Base design is EB63/Granberg with shortcuts and omissions.

Take a look at this: https://youtu.be/sXJmAhpAjeI I haven't tried to set the BFO in my uBitX, so I can't really vouch to this, but it makes sense and is easy to follow. It appears that it would

Joe, I have my TFT Display working fine. PTT and all. I have a question regarding bfo calibration. I am able to align it but unable to Save the bfo caiibration. I press the V Save button on the

Just taking a guess that it’s a push button wired to the CW Jack that when pushed its transmits CW as if your holding down a straight key. At least that’s how I’m planning on doing it this

Mike, could you please share details on how you did this? Thanks.

I ordered one just to have some more "fun" with. Being a broadcast engineer I love to rework something to make it work with something else, The one I ordered says from 20 mhz to 30 mhz it will do 250

Can't comment on the audio. It s been changed for V4. However if you expecting a lot of hiss that not something it does. Hook it to an antenna and tune around to see. You should hear an increase

Many Thanks Ian. You have help me to solve the problem. Firstly I have been pressing PTT and then keying up. When you described the changes I should expect and as I had no change just keying I

For those of you who are trying to learn Arduino programming, edX is offering a course, Arduino Programming, from novice to ninja. The course covers basic Arduino programming and connecting to and

I just finished building and installing the click eliminator in my uBITX and to my utter and absolutes amazement it worked the first time! I am an experienced kit builder but other then very simple

Does this tune up process work for Align the master clock on the version 4? When I press the encoder knob it begins to transmit.

The spur get visible when the drive is up. Generally for 10M that means well under 5W. Some are better than others but I know of three that at 2W on 10M do not pass even at 40db down.
