Analog pin A6 (connector P1, blue wire) is still currently free. It may be used in future arduino versions though. In the sketch, look for #define ANALOG_TUNING (A7) change that to #define

The capacitor on the tuning pot definately works as my spare Raduino, works fine. Phil - G7BZD

Have you added a 100pF cap on both sides of central wire? I did and after a while tuning was unresponsive. It turned out one cap was blown

Unfortunately the nano on a Raduino is soldered in place. Ahhh well, as My father used to say, I always do things the awkward way, set fire to the house to light a candle. Think its time i tidied the

According to the schematic, yellow isn't ground. Orange is. All three wires for the pot go right to the nano. So if there's not a blown trace, there's prolly a blown nano port. You may be able to get

Its Yellow wire GND connection for the tuning pot on connector P1 that i managed to short to +12v. So where do I find the correct bit of code to modify. Its still running v1.10 for now. Thanks Phil -

you have probably blown the analog line, move to another analog line, recompile the arduino sketch to use the new line. - f

I just managed to short my Raduino tuning connection ( yellow wire ) to 12v, display still works, but its tuning low at 6.78 or thereabouts, unresponsive to the pot. Any ideas if its a fixable issue,

hi i have ordered a dummy load with a voltage monitor point. i will see what i get with that terry

hope I am home for it

Just a reminder to note the time and frequency for Sunday, June 4.? The time has changed from the previous QSO night.

Same sound without antenna.? By tweaking the bfo you mean adding ?the 27pF cap to the board? Peter Parker mod) thanks

OK, I got 3 guys who wanted Raduino Board. It is the board and Nano, no LCD or Spacers. I did move the Regulator and add capacitors and a limiter resistor on the input. It is programmed with 1.13

Unplug the antenna and see the residual noise. If it drop dramatically then it could be local electrical. The speaker is distorting in the video. It will sound better in a box with low tones louder. I

Yup, 30v p-p into a 50 ohm antenna seen on a scope means 2.25 watts peak effective power of an SSB transmission. That 30v p-p is centered on ground, and is the maximum seen when we shout into the

With a waveform showing 30V P-P into a 50 ohm load the PEP would be = = = 2.25 watts Mike K5ESS Sent: Friday, June 02, 2017 5:17 PM To: [email protected] Subject: Re: [BITX20] power measure And he

Guys Someone made a PDF of the instructions I posted a month or so ago but I am on the road and don't have access to it or who made the PDF. I will be home Tuesday and can post it OR whoever did the

I'm in.

Me too! It is the the PCB with Nano programmed latest version. But, no LCD or standoffs includes. So I want to make sure that is understood. $20 shipped to any US buyer. So, I will give priority to

I have recived many pcbs from international sources that were packed and sent as Hans and Noel describe, sometimes taped to the largest sized thin card or heavy paper that will fit in the envelope, to
