Do you mean that you have low transmitter output? ?If so, could be that you need to bump up the gain at R136. ?See post?/g/BITX20/message/22112? But do not turn R136 up so high that you get distortion. ? ?Also maybe check out this post ?/g/BITX20/message/22252? Then ask John Smith if you have any questions. ?

Of course, there are many potential faults in the Bitx40 that could reduce transmitter output.?

Use a small plastic box that feels like a comfortable mic, and put the mic poking out of the face of it, and the button on the side. That one from Banggood has 8 pins. You would only need 4, two for the mic wires, and two for the button wires. And it's just wasteful to buy a mic only to rip it's guts out for a downgrade. ?Look for a small picture hanging parts box in a gift type tool box. Or ask a woman you know for something like that used for cosmetics. Or look for a small project enclosure box that looks like a small radio microphone. Here is an example of someone's photo in the emailed photos folder on this site. Otherwise get the cheapest Baofeng hand mic and hack it. It also has a speaker in it.

?I considered doing that. The biggest thing is that I want one of those mic cables because they coil up, and currently mine does not. Perhaps I just need to find a better cable for the one I have. The coiled cords are $10 everywhere I've looked, and this whole mic is $10. And it's not wasteful if it serves my purpose. I know I'll have to source an 8 pin connector for it- ?else buy a mating 4 pin connector set and replace them, which I could easily do. My concern isn't whether this is a good idea. My concern is- is there any reason it won't work?

Once again Jerry, that was exactly it. I replaced all but the last "}" and it compiled. When I tried to highlight "{" on #617 it wouldn't let me. It would go to ")" instead. Does that mean there wasn't a pair? It was much lower in the sketch than the replaced section at #541. When I dropped the cursor on other "{" markings it put a small box around it's mate.

I'll check it out tomorrow afternoon.?

Looks like you ripped out two bottom right curly braces. ?You should only rip out one of them. ?Compare what you ripped out with what I ripped out. ?And think hard about which left curly brace matches up with which right curly brace. ?Use the Arduino development environment (where it shows you a listing of the code and allows you to edit it). ?If you select one of the curly braces with the mouse as if you were going to cut-and-paste it, the matching curly brace will highlight. ?Play around with the working version of your code and see what matches up with what.

Not disappointed yet. ?That happens when I blow out the Raduino.

And yes, it is uphill both ways. ?At least part of it.

Hey everyone, I'm looking at options for a "real" microphone and ran across this one:

It's got an 3 wire electret mic, not sure about the circuit it has. Will I need to bypass most of that to use it with the BITX40? Or should I gut it and put in the mic that came with the BITX40? Thanks a lot for any recommendations.?

And we never heard from him again.

I think Jerry deserves a gold crown for his patience, and generosity for helping others and going to the post office 90 miles in the snow and ice uphill both ways.

Undoubtedly he will be disappointed with it at this point after nearly two months of anticipation. Or, he will have retreated into his shack to explore the darker elements of experimentation with the two BITX 40 boards, Raduino's, and Frankenstein's journals. ? ?

Ok, I copied the whole section and replaced the whole section in the sketch. And got the same error. Here is more detail- after turning line numbers it highlights in pink line #617. Here is the line- "void loop(){". This is part of the original code, and it doesn't cause an error in it's original form.

And the latest error message is the same as posted before. Stand by for more details.

This is the whole section I replaced-

? // the tuning knob is at neither extremities, tune the signals as usual

? else if (knob != old_knob){

? ? ?frequency = baseTune + (50l * knob);

? ? ?old_knob = knob;

? ? ?setFrequency(frequency);

? ? ?updateDisplay();

? }

}

So am I still too thick?

I just completed my Bit-X 40 kit and when powering up I have a blinking red light on the Raduino board. I also get a clinking noise in the audio whenever the light flashes. ?I also have no numbers on the freq. readout but it does light up. ?I have not yet set up the radio and this may be part of the problem. ?Any help would be appreciated as I am a newbie on this radio.

John Smith,

Did you see this note in my follow-up email the next morning:

> ?Remove the extraneous final 3 lines about the tone and replace them with a closing "}".?

Sounds like you might be missing the final "}".

You said: ? ?"And I was just inserting the new lines between original lines of code."

You are not "just inserting" . ?You are removing some old code and replacing it with new code. Replace the lines of code I have included in the mail history here with the following lines (this time I managed to include that final "}" in my copy-and-paste). ?If you still get errors, make sure that for every "{" there is a matching "}" further down in the code. ?If you put the cursor on one of those within the Arduino development environment, it will probably highlight the matching other curly brace for you.

  // the tuning knob is at neither extremities, tune the signals as usual
  else if (knob != old_knob){
    static char dir_knob;
    if ( (knob>old_knob) && ((dir_knob==1) || ((knob-old_knob) >5)) ||
         (knob<old_knob) && ((dir_knob==0) || ((old_knob-knob) >5)) )   {
       if (knob>old_knob) {
            dir_knob=1;
            frequency = baseTune + (50l * (knob-5));
       } else {
            dir_knob=0;
            frequency = baseTune + (50l * knob);
       }
       old_knob = knob;
       setFrequency(frequency);
       updateDisplay();
    }
  }

Got a note in the mailbox Saturday saying?RN187017248IN?(ordered Dec 23)?was at the PO, but registered mail so had to sign for it. ?They close early on Saturday, Monday was a holiday here (Washington's birthday) and Tuesday we had yet another nasty winter storm storm. ?So drove the 90 miles round-trip to our post office today, half of that over ice and snow, some with chains on the rears. ?Found that?RN18702575IN (ordered Jan 30?as a backup since the first wasn't showing up) had also arrived on Feb 21. ? Both appear to be in good shape.

The clerks at the local post office have been most helpful.? Though they cannot give me an electronic copy of what their tracking system shows, they could read off a list of places and dates that the two packages have been.?

RN187017248IN , ordered on Dec 23, 2016 ? (What a long strange trip it's been)
Was packaged in a plastic box and a fabric cover, a corner of the plastic box was crushed but no damage done to the contents.
Barcode looks low-res and a bit too light on ink, perhaps smudged a bit from the journey.? The notation "Address Encoding" in the tracking information suggests to our postal clerk that there was trouble routing this package to its destination, likely due to the faulty barcode.? When signing for the package, she first scanned it with a hand wand, it took a couple attempts but the barcode was readable.? The printed address is perfectly legible and correct, 30 seconds of human intervention should have sent this package on its way to me if a sorting machine had trouble with it.? Instead it went back to IndiaPost (but not to hfsigs), IndiaPost promptly sent it to the US again. ?Labels on the package look original, I don't think IndiaPost found need to adjust anything.

> ?John Backo?Feb 4???#21514: ? I noticed the address label from India was an inkjet printout of the order.

I think that was it. The barcode label on the first one was marginal, probably got kicked to the side by some sorting machine. We had some really nasty weather here in January, and USPS was likely understaffed with some employees not able to get in due to winter weather. That may explain some of the extra stops that first package made, and the lack of human attention to read a perfectly legible address. I'm sending this info to hfsigs, along with a photo of the barcode.

I gotta show ya how much of a noob I am. I started with copy and pasting Jerry's code into mine with the tune input pin change because I fried it in the beginning, and got errors. Then went with Jack's slightly different code and got the same errors. Both times, the errors were with the original code elements. And I was just inserting the new lines between original lines of code. Well here's what I got.

Arduino: 1.8.1 (Windows 7), Board: "Arduino Nano, ATmega328"

C:\Users\John\Documents\Arduino\Raduino_code_pin_a7_to_a6_number_2\Raduino_code_pin_a7_to_a6_number_2.ino: In function 'void doTuning()':

Raduino_code_pin_a7_to_a6_number_2:572: error: a function-definition is not allowed here before '{' token

?{

?^

Raduino_code_pin_a7_to_a6_number_2:621: error: a function-definition is not allowed here before '{' token

?void loop(){

? ? ? ? ? ? ^

Raduino_code_pin_a7_to_a6_number_2:643: error: expected '}' at end of input

?}

?^

exit status 1

a function-definition is not allowed here before '{' token

These did not cause errors before the addition.

Perhaps downloading a compiled sketch would be easier.
