At this point I have no intention of using my ?BITX for CW.? I understand I still need the pull up resistor between pins 2 and 3 on the Raduino.? I am trying to eliminate as many unnecessary wires

So far I have to say the Han's QCX concept is really neat. It uses 6 passive components and provides an on-board DC, AC/RF meter, RF power meter, frequency meter and signal generator. Brilliant. That

Check the wiring at the potentiometer. I indeed reversed two of them, so as switched on the volume was highest. Maybe that was one cause of the failing TDA without the WX mark. Volume is plenty as

I agree with you. I have one on order. If you already have a good IF system (i.e. the ubitx) why spend money duplicating it? tim ab0wr "K9HZ" <bill@...> wrote:

For me the easiest thing to do would be to have a socketed Nano (I know - cost!). You could then plug in a second Nano with diagnostic software to chase outboard problems. Inboard problems with the

I'm having problems uploading to my Nano since I did upload a hex file successfully. I cannot get even the blink example to load now. NADA. But the hex (avrdude) loader still will upload hex files. It

Arv, I have a spectrum analyzer. I use a two-tone generator. There is no issue with spurious microphone response. While the two-tone gen is just a standard kit, I can't see any distortion on my

Seconded, Dave! I'm just a little younger (67, 51 a Ham) and am continually enthused, even if constrained. My Bitx-40 is stalled, and probably won't be finished - I've hopes of being able to afford a

Yes, Jerry - a case of PEBCAK at the webage's creation. Lack of consultation with a competent Tech, and lack of knowledge of keyboard and capability of software commonly at hand. Any word-processor

Why do you need the hex files when the source code is available? Jack, W8TEE

For the life of me I can't find the compiled hex files. Help! Bo W4GHV

For those Radiuno suppliers that do not know; ?Macintosh users have significant trouble with the CH340/CH341 Arduino clones. ? ? The Chinese vendor that makes that chip has done a very poor job

Yes, a slight tweek on the pot made a great improvement in my displays read ability.

I ordered new chips and sockets from Amazon and slow-shipping because its not an amazon fulfilled product and shipping was going to be multiples of the cost of the parts.... so no fun for a few

I took apart a Sun Microsystems mainframe while I was studying Digital Electronics in tech school 1 block from 42nd street in Manhattan in the late 80’s. I was too young for the mainframe era but I

Exactly. I have one for 6M and another for 4M. Very small and easily fitted in a case with the μbits. If you want higher power that's another issue. With just the barefoot transverter and a simple

I will never again build a kit that doesn’t have the diagnostic tools built in. I’ve seen the light. Take the uBITx for example. The Arduino needs to be working in order for the radio to work.

Thanks for the replies. I have written some ino code for other projects using arduino ide.??For something like this I am out of my league probably. Always run the compile test feature before I
