This my build of YouTube user jmhrvy1947 Antenna Analyzer • DIY No Frills AD9850/Arduino Antenna ... It has been a rather lengthy project, but has been worth it because it is very useful. The author of this project has changed the sketch since the first video, so make sure to check out his github account.

Hey Joel, nice project! I will definitely follow up on this.

Hi Mark, the bezel I used unfortunately came from a discarded replacement face plate for a Chinese X1M multi band QRP transceiver. They had misspelled the word "Transceiver", so they sent us a new one, so I peeled the plastic bezel off before discarding the face plate thinking it might come in handy someday. I have looked for them since then, but haven't found a source yet. Sorry, Joel KB6QVI.

Quite interesting project . Hi Joel, Is it possible to upload a hex file of the firmware in Github. Further, can this be modified till 56mhz

Hi Joel, could you say where you got the surround for the OLED? I notice in Jmhrvy1947 comments you mentioned building a buffer amp and I wondered if you did and if that improved the results at higher frequencies? Many thanks Mark

What should I change so that the frequency covering 435Mhz? For me it would be very useful from 433MHz to 435Mhz .

Nice job 👍🏻

I built a very similar(same dds using the nano) and I'm having hell trying to learn the code aspect. I have gotten u8glib file for the oled and the code for the rest from another website but it's getting errors when checking it. I'm lost as to what to do.

Thanks John, I'm still testing it for accuracy, sometimes it's right on the button and other times way off in its test results. I can't figure why. Joel KB6QVI

Hi Carlos, you must use a Arduino micro controller to control the frequency of the AD9850.
@Disodium85 8 years ago

I really like that enclosure. Where did you get that? Also, any pictures of the inside and how you mounted everything?
@PU2PUJ 8 years ago

Hello I ask if you could send Antenna Analyzer schematic (controler conections).
@caulktel 8 years ago

Yes, I built it.
@caulktel 8 years ago

Hi PU2PUJ, here is link to all files. github.com/jmharvey1/DDS_AD9850_AntennaAnalyzer look inside the Eagle files folder.
