Ah, yes. I ordered a kite string winder that took 3 months to arrive. I ate a lot of lousy cereal to get it, even at 7 yrs old I wondered if it was coming "slow boat from China"

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

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

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).

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

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:
