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

Upgrading Displays to I2C
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

Re: Faulty Mini 360 Buck voltage regulator in the nano-DDS kit
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
While Farrukh is working on a modification to the Beta PCB, I'm continuing to work on the software. Something most AA's won't let you do is store a scan for use later. The attached photo shows a

Re: 49er transceiver build by W0MNA
Jack, What you were demonstrating to me on your new AA device really looked interesting and definitely worth building. While you were showing me the device I was also thinking of how I could possibly

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

Re: In need of some vfo help
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

Re: 49er transceiver build by W0MNA
Interesting on the two calls. Never thought to look them up. I was lucky and ended up with a call ending in MNA when I started but have over the years modified it a bit with WN0, AB0, WB0 and now

Re: 49er transceiver build by W0MNA

Jack, Thanks for the nice comments on the transceiver and for creating the design to start with. Some pretty tough competition at this build session. Really looking forward to building your next

Re: 49er transceiver build by W0MNA
Norbert, I found the case at a hamfest for $3.00. It had something else in it at one time but was empty when I bought it. I was able to use the former front panel as the back panel since it has an LED
