Re: Modifying Frequency Range of DDS VFO
Hi, Thanks for posting the code for a wider range VFO. I can't get the file to compile. The compiler wants an LCD.h file which is not part of the original VFO folder. I have tried several LCD.h files

Re: Faulty Mini 360 Buck voltage regulator in the nano-DDS kit
The horse may be bloody but isn't dead yet. Certainly most of the circuits we amateurs build are very tolerant of values. In most cases close enough is good enough. One place where I break into my

Re: Faulty Mini 360 Buck voltage regulator in the nano-DDS kit
Hi Hank: Believe me, I understand the economics of this situation. (Most people probably don't know it, but my Ph.D. is in economics, not EE.) Still, placing QA on the buyer is not how it should work.

Re: Faulty Mini 360 Buck voltage regulator in the nano-DDS kit
I get it that we shouldn't have to resort to doing our own QA. However the problem is so widespread that it is impossible to control. To a lessor extent I give the vendor a pass. He just gets a

Re: Faulty Mini 360 Buck voltage regulator in the nano-DDS kit
Anytime someone finds a vendor, domestic or foreign, who sells product that is out of spec, they need to post that vendor's name on this forum. There's no need for this kind of crap and if enough of

In my junk box I have a supply of 2x16 LCD displays. These all have the analog interface where it takes several wires from the microprocessor to the display to make it work. This project introduced me

It has been my observation that parts sourced from China obtained through eBay can sometimes have sketchy quality control. Recently I obtained 200 .1uf 50v ceramic caps from one of the more respected

Faulty Mini 360 Buck voltage regulator in the nano-DDS kit
Well I finally got to building the nano-DDS kit, Nice, very nice. But I had difficulty with the mini360 regulator board. I could not get it to adjust below 8.7v, I had a few in my stock box so no

Re: 49er transceiver build by W0MNA
Gary: Yes, the new AA will be completely portable, but will allow you to save scans to an SD card, which can then be sent to a PC via a USB connection. Since it's stored as a CSV file, it can be input

Peter, Besides making sure you are using the correct I2C library for the DDS/49-er radio, you need to make sure that you are calling the display in the code but its proper address. If you head over to
