Jack: Do you have a preferred supplier for the Nano modules? James

I2C has several speed modes.? I think as slow as 240Khz or thereabouts. 400 is the popular fast speed? Here is a good starting place for looking at I2c. Sparkfun and AdaFruit sure have so good

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

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

You're right! I didn't look at the schematic to see if the Si5351 was using the I2C interface, which it is. My bad... Jack, W8TEE To: [email protected] Sent: Wednesday, March 15, 2017 1:08 PM

Raj: ?Thanks for the clarification. ?And yes, this might apply to digital VFOs as well. ?The mixer is having trouble with images from the fourth harmonic on both analog and digital vfo's. ?A

Jack, I believe the A4 and A5 lines are already being used for the I2C to the SI5351. Am I missing something? Mike K5ESS Sent: Wednesday, March 15, 2017 11:32 AM To: [email protected] Subject:

Hi, I get a birdie/oscillation at almost exactly 7200 when tuning the receiver. ?Not sure if this is a common problem or what the solution might be, if any. A relatively minor problem.

Comes in handy right now. ?The Si5351 uses the I2C interface, so the etherkit Si5351 library silently grabs A4,A5. ? This might make it difficult to have other I2C devices on that bus, even if they

That IndiaPost RN*** ?tracking number can be found on the web, where you might see that it got put into a bag at MumbaiAir, and then silence. ?But the USPS has their own tracking system, no web

M3 fine thread, I believe. About 1.25 sixteenths of an inch, if that makes any sense.

Also note that Farhan wisely left A4 and A5 open as these are often used for the clock (SCL) and data (SDA) lines of the I2C interface. That foresight could come in handy later on... Jack, W8TEE To:

This is how to connect. * Though, this can be assigned anyway, for this application of the Arduino, we will make the following * assignment * A2 will connect to the PTT line, which is the usually a

Hello, tnx for ansver. I dont have board yet. Working only for testting. I burn program in arduino and conncet display. Working. On drawing for dds have 3 conectors, P2 for display, P1 for control and

Good morning Alan. Happy to see you join the BitX ranks. Wayne, Eldon, Jeff, and a bunch of us from the Tacoma club are having a ball playing with these things. To your question; Typical delivery

When you are in the Arduino IDE and uploading the sketch, can you see the TX/RX LED's flashing during the upload? What message(s) do you see issued by the IDE. If the Nano is powered by the USB cable,

Minor but rather important detail, my kit arrived with the two ep connectors, but one of them was missing the knurled nut. What would you call those connectors, besides EP connectors, in order to buy

My Bitxv4 came in on 3/7 C107 is in there. My Bitx40 hasn't workered yet. Just audio noise. Display all 16 character positions are black. I also recv'd the mystery SMD cap. Did get the 0.1 for the
