Re: Raduino

I noticed that the shipper from China on eBay listed the Delivery Estimate to be between March 31 and May 9. ?Wow, that reminds me of the wait for stuff I ordered from Battle Creek, Michigan when I was a child! ?Almost two months seems like a very long wait time, if it is indeed true. Mark, W5MCU |

Re: Raduino
¿ªÔÆÌåÓý
I have bought 5 at a time.? Maybe $15.? I have bought about 12 of
them. They are sealed individually with a part # 5401274. I now have a few dead ones, that I must of made happen.? I have yet to try to re-load the boot program? Usually they just quit connecting to the PC as a recognizable port.
I don't like using the regulator on them at higher voltages or currents (like LCD Backlight current). Ok for 9V or so with no big current loads on nano.? Otherwise feed the 5V terminal with an off nano regulator.
Mike, WA6ISP Here is eBay, that is where I bought mine.

Re: Raduino

Not really. I've had good luck with all so far, so I tend to buy the least expensive. Lately, I'm using the Arduino Mega 2560 Pro Mini and there aren't too many of them yet. (See: ebay?162264493523). However, I usually buy 10 at a time and sell what I don't need to my club members. This helps us all since they will discount the price in quantity.

Re: Bitx40 another Raduino(?) problem
I bought a BITX40 board before the Raduino was available, so had to build my own. My version is very simple, a arduino Pro Mini instead of a Nano, si5351, and a I2C OLED display. Basically the same thing I had used in converting a Chinese 40 meter cw transceiver. There was no problem with using the same I2C bus for controlling the two devices.

Re: Bitx40 another Raduino(?) problem

I'm not sure. The I2C interface can handle quite a few devices and the board does have the pullup resistors in place. However, given what the Si5351 is busy doing, I wonder how much bus traffic the interface can handle given that the interface is being controlled by a 16MHz clock. I don't have the EE background to answer that.

Re: Shooing the harmonics
As you have suggested, this 4'th harmonic is a problem when running the VFO at 5mhz. ?On the Raduino, one possible fix is to run the VFO on the high side, at 19mhz ?But with a vfo at 19mhz for operating 7mhz LSB, the crystal filter does not have so steep a skirt on the carrier side where we need maximum attenuation. ?So your fix at 4.8mhz might be the best solution. ?On the new uBitx, I'd like to think the extra crystals in the filter will allow us to not worry so much about crystal filter skirts.
