I ordered your book and should get it in just a few days. I look forward to reading it. As for the filter schematic, I have not been able to find it. I am brand new to Yahoo Groups so I am sure I will

There are some thoughts on this in Chapter 16 of the Arduino Projects for Amateur Radio book. Since the basic design of the VFO was from the book, with a few mods by Farrukh, it should be able to work

Hi Lou: This is great...and the exact reason we created this Forum in the first place! I'm up to my butt in alligators right now or I'd volunteer, but I'm sure someone out there will take you up on

Probably not. However, an earlier post of mine has an inexpensive Broadcast Interference (BCI) filter that I built and works great. I have an AM station a few miles from my house and that was all I

If anyone else wants a general HF VFO, see Chapter 16 in the Arduino Projects for Amateur Radio book. The basic design for the VFO was based on that hardware/software with some modifications by

I have the VFO section working properly and I'd like to add it to a more substantial QRP kit than the Forty-9er. Perhaps the OHR 100A, or a MFJ kit. I wonder if anyone has information about a

My first build with the VFO and Forty-9er failed. The VFO worked fine, but the Forty-9er was subject to very (VERY) strong AM broadcast interference from a local station. I have to ask...would

Hi Lee, I have modified my DDS VFO for 1 to 30 MHz with a very basic display. The modification and display I am sure could be improved (I am not a SW engineer) but the frequency output now meets my

I have RX offset working. Unfortunately it requires a hardware mod. Currently you can sense the T/R state of the 49er by reading the RXTXPIN (set pinmode to input (no pullup!)) it will read high for

Has anyone looked into modifying the frequency range of the DDS VFO Kit (QST March 2016)? I have now completed two of the DDS VFO kits and would like to try re-purposing one or both of them for other

Hi, My apologies for extended absence from the discussion forum. The blue/white pot on the "Forty-9er" board in the picture being referenced in this thread is indeed NOT to be installed. I had

Jack, Yes, adjusting the regulator for output of 5VDC was not a problem. I checked the voltage again while observing the problem and it was spot on 5V. Thanks, Lee KG5VU

Has anyone else experienced power problems with the DDS VFO kit (QST Mar16) ?? When I first powered up the board, the VFO worked but when I monitored the signal on a hf receiver the signal sounded
