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: part swap anyone?
Debco has a 10 pack of 5.1V 1W zener diodes for $1.25 and a 2 pack of 22uH chokes for $2. I buy a lot of stuff from them...husband and wife team, both hams, and great people. Debco Electronics |

Re: Looking to gather the parts
Well, my update is that I made it back from FDIM and have been checking out some new toys. I ordered the remaining parts/modules for the DDS VFO and should have all that in a few weeks. In the

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: In need of some vfo help
The listing is no longer viewable. If you can, write the vendor and ask which libraries the display uses. Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Tuesday, May 24, 2016 9:15 PM

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
Gary: You did a good job, as I said. BTW, I wondered if anyone had the call W0MAN, and it turns out a lady has it, but a guy has W0MEN. Interesting!? I'll keep you posted on the AA project. I have

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

Re: 49er transceiver build by W0MNA
I saw Gary's Forty-9er at the Four Days In May (FDIM) conference in Fairborn, OH (suburb of Dayton) that takes place just before the Dayton hamfest. The rig looks even better than the photos. I know

Re: 49er transceiver build by W0MNA
Hi! Excellent build, looks very Pro. Where did you get the case ? I see that it has a volume knob and the filter capability sounds like a pretty cool feature. Thanks for sharing the pics. 73s Norbert

Re: In need of some vfo help
I had this exact problem with my display when I booted the Nano for the first time only for the purpose of checking the code with the I2C display. The 49-er hadn't been built yet. If I remember

Re: In need of some vfo help
I'm not sure where you got the LCD display, but it does look like some of the characters are being displayed correctly. If you bought the display from Yourduino.com, I would suggest loading a sample
