What's the difference between this method of tuning and that of the Raduino? It appears to be the same only with a voltage readout. Joel KB6QVI

Folks have been having trouble Finding Don's Video.?? So I put it on YouTube to make it more accessible: Click on this link: Don ND6T Video of AD9850 Shuttle Tuner for BITX 40 | | | | | | | | | | |

Hi OM Where can I purchase the Radiono board. Will they be available on the Hfsigs site? Thanks Ross Bell K7RSB

Don Has the shuttle sketch been posted? If not I would like a copy Art. N2AJO Sent from my iPhone

Ok, there also are good arguments for separating the VFO from main board. For me this also wasn't the mayor point. Compared to this, later use of easy pluggable BPF and LPF filters would be of higher

Yes there is a link, and if you scroll down you will see the video referenced. Typical for a blogspot is that there will be new articles posted. http://bitxhacks.blogspot.com Verzonden: 14 January,

Bill, sorry but there is no link there for a video! I click on the photo in the blog post and it's just a photo, no video! Roy WA0YMH [email protected]> wrote:

I am not so sure that this is a good idea. If one reads the comments about the various DDS units, a common problem area is controlling the noise. Putting the DDS on the same board as the rest of the

If you "remote" the 510 by adding even a small amount of wire you run the risk of turning that amplifier into a big ugly oscillator (been there, done that!). One of the reasons the BITX 40 amp is so

Thanks, Bill. On another note, thanks for Soldersmoke and your QRP book, which I read 3-4 years old. Will take a look at your information. 73 - w4usf
