Excellent. Maybe add a few configurable frequency presets to the code? 10M would seem likely to be used often. Maybe some type of calibration code?

Will it be possible to make a 2 channel version using 2 AD9850s?

[@herbertsusmann986]

Considering that that DDS board is based on what looks to me to be a normal non-oven crystal oscillator the frequency accuracy is pretty good. The one I have is off just a bit but still very good. I can get mine to go well beyond 30 MHz although the wave form starts to look a bit ratty.

Well done! I wonder if making a front panel for it would be an interesting video? I'm thinking maybe aluminium with the lettering etched using ferric chloride. You may need to glue some standoffs to anchor it. Over kill?

[@IMSAIGuy]

over kill for me, but it would look nice.

[@JohnTarbox]

Looking for ideas? How about a QRP transmitter?

[@bobkozlarekwa2sqq59]

You are one very busy RUclipsr! Are you active on HF?

[@IMSAIGuy]

I turn on FT8 once in a rare while

[@PapasDino]

Lots of space inside that enclosure for a broadband (hopefully flat) amp and electronic attenuator!

[@stephaneshm3043]

Very good ideas RF Power Meter

[@qwaqwa1960]

Sweep...??

[@IMSAIGuy]

it would be very slow but good idea. I'm working on an audio sweeper and it is not working out very well.
