I did something similar and fed the nano 12v on one of it's inputs which killed it. Plug a mini-USB cable into it and see if you can communicate with it via the Arduino IDE. The Serial monitor ought

I also tried all values and the birdie remained firmly on it's perch. Interestingly it seemed quietest when not setting a value, do we know what the default value is if it's not set ?

A 1uF of 16V or more will do. the +ve lead of capacitor to the circuit and -ve to external audio input. 73 Raj vu2zap

I feel bad about making everyone run out of the room before Randy K7AGE got to read an answer to his question. He's a pretty good Youtuber. His video on a 2 Meter out door ground plane antenna has

I am glad someone agrees with me about something. But Arv talked about many things that I didn't. All good points though. But here is where I want to split a hair. I was quoting someone about the

I don't know anywhere you will be able to order a uBITX so I doubt the lack of a dedicated blog will be an issue. Bill, VK7MX

Note this from DK7IH (via CO7WT). I have not checked the code, but this is the probable source of the "clicking" in the Raduino. See the CO7WT sketch for more information. "Some authors join the two

I also wired up the jack for headphones & the audio is MUCH better at high volumes. Must be junky speakers..

I heard VE6CQ with a nice signal level tonight - the band just comes & goes, it seems. I gotta get the TX side set up & going now!

Maybe you missed it:?http://www.hfsigs.com/

For what it's worth I uploaded the 1.05 sketch and it made the Birdie at 7.200 much worse. I tried all the settings and 2ma was the best results for my board. At 2ma and tidying up some of the leads

John Smith.. I will agree with you...and finally a fixed copy of software!!! YEA!!!! My unit on the breadboard, and all the extra's in a box under it (including a case, matching knobs, even an

The bands have been quiet the pass few days, I notice that on my Kenwood TS-520 there is a lot of noise and not so much on the Bitx however I still hear those far out stations just not as much noise

It should be adjusted to draw 1 amp at the final, even with 24 volts. More current draw causes a lot more heat and possibly damage to the final or other circuitry including PCB traces. Like a wire

The serial number is N3-476. john AD5YE

I have tried to hear W1AW, but no luck so far. I suspect my antenna, I'm going to try something different, maybe a vertical.

I believe I've read 1000uF electrolytic a few times in regards to using a dynamic mic. Same with line-in. 6V rated or higher is best. You want a capacitor rated higher than the voltage in the circuit.

John I sort of disagree with your assumption that there is a cultural difference between Indian and American hams. What there does seem to be are differences in technical knowledge, which manifests

Hi Craig! I did not try 24 V as I do not have a power supply that goes as high. I tried 19.6 V from Li battery pack for power tools and when transmitting I get about 1.8 A current draw and about 15

i dont have another speaker, i wired up the headphone jack though and put a headset on it and it sounds great at higher volume.
