Re: Tracking shipment
You get tracking number when paypall notifies on shipment. You can use India Post tracker (aftership). Probably when it arrives at your country you local carrier will address new one. Could at least

Tracking shipment
Can anyone that's already received a BITX40 tell me if you get any emails that confirm when the order is shipped or even maybe a tracking number? Or is it just a surprise when it shows up? Thanks,

Low current drawn by PA of BITX40
Hai all The BITX40 board arrived intact and connected and put in a neat metallic cabinet. Rx is working excellently well. Unfortunately the Tx is yet to perform as prescribed. The PA is drawing only

My BITX40 has arrived...
Compliments of the season to you all. I have spent the last 3 days putting my rig together and playing around with it. It is temporarily mounted in a plastic food container and receives very well. It

Re: tuning step size for the SI5351 / Radunio version
Hello All, I have been watching all the posts over the last few weeks regarding the VFO/DDS question for the Bitx40, Let me say that I got one of the earlier Bitx40's and immediately converted it to

Re: tuning step size for the SI5351 / Radunio version
Sent from an iPhone, don't ask whose. When the ADC is set to 5V full scale the reference is the 5V ADC supply line so it is ratiometric, meaning the ADC reading (in this case) is independent of the

Re: tuning step size for the SI5351 / Radunio version
I'm using the 5V supply from the Nano but they sometimes are lower like 4.7, so I thought that might affect the upper end. I have not measured it yet, I will do that tomorrow. I do have .1mfd cap

Re: tuning step size for the SI5351 / Radunio version
Rotary encoder also contributed noise when touched, like AK47. Good solution... Rotary encoder has in built push button that can be used as step size, 1 Hz or 10 Mhz... Carbon film Pot don't last

Re: tuning step size for the SI5351 / Radunio version
This could be what I call a "corner bug"...a bug that hides at the extremes of a variable. I haven't check this yet, but keep in mind that the converter has 10 bit resolution, so the range is 0-1023,

Re: tuning step size for the SI5351 / Radunio version
At times, the noise contributes to this as well. Solder a 0.1uf capacitor across the pot's ground and wiper lugs. - f

Re: tuning step size for the SI5351 / Radunio version
It should work if you have derived the same power line as the Arduino's 5v line. in the function doTuning(..) there is a line that triggers the step up beyond 1010, you could reduce the 1010 to 950

Re: tuning step size for the SI5351 / Radunio version
Farhan, I breadboarded your Raduino to try it out, and I have to say I rather like it, however sometimes when I turn the pot all the way clockwise it won't go into the mode that counts up at a higher

Re: tuning step size for the SI5351 / Radunio version
I do use a rotary encoder to tune my Forty-9er (see March, 2016, QST) and will likely soon add one to the BITX40 I just bought. The increment is an issue that is often one of personal preference. For

Re: tuning step size for the SI5351 / Radunio version
Ashhan, Thanks for the reply. ?Yes, I understand the tuning element is a pot driving an ADC and the limitations of cheap rotary encoders. ? 50 hz is a pretty big tuning step, I just played around

John, the step size is 50 Hz as shipped. the tuninng is not by a rotary encoder. it is with a potentiometer. here is how it works: - The tuning pot is connected to the ground and 5v lines. The
