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

Email the designer and he will help. Forgot his call. The one who sells the vfos. See March QST for info.

A 0.1uF disc is correct for C9. Download the latest manual revision,although it doesn't appear on Farruk's site any more?! ... Another Jim - AB1BR

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

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

Hi Lou am game to test this. Let me know if you are still looking for a volunteer... AB6UI

CP9 is a disk (104, 0.01uF) and not an electrolytic. Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Friday, June 3, 2016 7:52 PM Subject: [SoftwareControlledHamRadio] Value of CP9 on

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

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,

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

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

Bo, I see you did provide a name and call in one of your posts. I apologize for missing that, but the rest of my comments stand. Lou W2ROW

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

The BCI filter is pictured in the 5th and 6th photos. I'll take a look at the other issues this weekend. Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Thursday, June 2, 2016 5:29 PM

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

Jack had provisions for RIT but it is not implemented. I had to eliminate the delay loop associated with it to get things going.
