Re: Mystery of R-0 ZERO
Jack, you've gone thru a lot with me and others about the TWO errors on your excellent article! I'm thoroughly enjoying the tinkering time, using my scope, etc. No rush to make a QSO, but I'm getting

Re: Mystery of R-0 ZERO
Email the designer and he will help. Forgot his call. The one who sells the vfos. See March QST for info.

Re: DDS VFO TXOffset Function
Well I did implement the mod. But when I went to reflash it did not work without a few minor changes. I have attached the file that worked for me. To see the changes I made just look for the lines

Mystery of R-0 ZERO
I completed my 1st 49er DDS VFO several weeks ago and its working great. (see photo) I am in the process of putting together a 2nd one so ordered another 49er kit from EBAY. This one is slightly

Value of CP9 on the Forty-9er
I am building the Forty-9er (VFO is completed) and hit a snag. The PCB shows CP9 as an electrolytic and the schematic shows it as a 0.1uF disc. To make things more confusing, I seem to recall mention

Re: Questions/errors in Arduino sketch
Yep that's the one I mentioned in my original post. I was excited to find out about this group to find someone else that tried this project. When I found code with a later date i jumped at it,

Re: Questions/errors in Arduino sketch
Ok I see the problem(s). First of all I did not post the frequency expansion code. I posted the RXOFFSET code which uses the correct D4 for the rotator switch pin. The frequency expansion code does

Re: Questions/errors in Arduino sketch
I think another apology is in order after you look at the code/sketch that is posted here. The one that expanded the frequency range. It clearly says 7 no matter how you read the schematic! 73, W4GHV

Hello whoever you are (a name or call would be nice). I assume you are referring to the code I posted with RX offset added. I assure you the code does work correctly as does the the original sketch

Re: Questions/errors in Arduino sketch
Jack I know we discussed it earlier, but when I saw a new/updated program here I figured things were different. The program here, in the downloads, will not work since it still has the original error

I thought I would add the freq coverage mod, and the original problems/questions popped back up. The ROTARYSWITCHPIN is connected to D4 not D7 it is connected to pin 21 on J1 (nothing) The RIT pin is

Re: Another 49er DDS VFO is alive
Jack had provisions for RIT but it is not implemented. I had to eliminate the delay loop associated with it to get things going.
