It is brown wire pin 6 on the connector of Raduino and connects to Bump Switch on Encoder. -- Mike Hagen, WA6ISP 10917 Bryant Street Yucaipa, Ca. 92399 (909) 918-0058 PayPal ID

It is in Preferences top left of IDE. Mike, who actually Likes Arduino IDE, except the Word "Sketch".? Sketches are for Kids, like Trix! The only compilers I really got along with was MicroChips

I am still adding a Tune Button as I did on BitX.? It offsets the Mixer for some RF Drive and plunks in the Xmit Relay. I am running out of panel space, the Key Jack is going on the back.? I also

Hi, I've just released raduino v2.02 for BitX40, download it from https://github.com/amunters/bitx40-raduino-v2 In this release: * Fixed another bug in the calibration procedure * Slightly changed

The first blow up was (I thought) I put the I2C connector backwards on the LCD.? It is not polarized there. I hard wired with shrink that end,? and the other end is Molex polarized. Then

Did you calibrate the VFO and BFO? The BFO signal is now generated by the si5351, so if it's not calibrated precisely then the BFO frequency will be off, resulting in an unnatural (sharp or dull)

Good question. But since Mike was not specific, I'll assume it was his error and not something I need to know about. Perhaps 12 power from the uBitx got wired into some MegaPro signal pin.? Jerry,

After looking at the latest code, I think you are right Jack. It seems the red wire is assigned as the function button and its going to the encoder switch. He must have abandoned seperate function

The earlier version used a combination of pot and function button. This has been replaced by the rotary encoder with integral pushbutton - a much better solution. We have just one spare I/O (an

You'd only need one of the amplifiers in each bi-directional pair.? My take (I'm also working on an RX build) is that since everything has 50Ω in/out, we can think in 'module' terms.? Here's a look

Just finished an interface for the bitx with help from David K4DBZ. After some trial and error with the inverter for the dtr signal its a big win! FTDI with an Easydigi interface and a 4 part inverter

Ouch Mike! The error is actually on the uBITX? Bill, VK7MX

I’m not so sure about that Jack, he talked about holding the function button down while tuning to make large changes in frequency, in fact he did it on camera. Maybe the firmware has evolved beyond

In that process Jack could we have a look at the current draw of the TFT? I haven't commissioned my VFO/TFT for the BITX40 yet but the current draw on the Antenna Analyser, which I think uses the same

Hello all, While awaiting my ordered Ubitx to arrive I have been playing with the idea of using the Ubitx design to make a small, compact general coverage SSB receiver for the hambands and for

I'm pretty sure he was referring to the push button on the encoder. Jack, W8TEE To: [email protected] Sent: Tuesday, December 19, 2017 4:54 PM Subject: Re: [BITX20] uBitX up and running I

I received mine at 11AM this morning and I made my first 40 meter contact at 1 PM and that's after eating lunch and taking a short nap. Very nice indeed. Does anybody know where the Function button

there are high level harmonics and demodulates in the product detector so I hear in the speaker a sharp sound

That's good news Simon. Did it come India Post? Bill, VK7MX

Use your voltmeter on the lowest voltage setting to test each wire segment under load. Just put your leads across each one. If things were perfect, you'd get no reading. When you do, examine
