Raspberry Pi Based DDS-VFO for my 1970-era Drake 4-Line Tube Ham Radio

[@googlegok9637]

Thank you for not drilling any holes in that fine old radio.

[@CheshireNoir]

Enjoyed the video. A nifty way of approaching things.

Funciona no DRAKE TR4-C?

[@netdudeuk]

Thanks for sharing. Another great project.

Could you not have the Raspberry PI driving a MC145156 to control a VCO that goes to the filter and buffer amplifiers.

[@tubeDude48]

I would have gone with an Arduino. Also, how about offering the PCB.

[@benjaminmeadows1380]

I have three different frequency counters but on 10 meters saying 30 m but on 20 meter says 12 Meg so do I buffer to show the right frequency

EFHW antennas are great, do you have a counterpoise attached to yours? I'd suggest a 17ft piece of wire attached to the shield/ground to help with your "RF in the shack" issue. Great vid, long time fine of your channel.

just a tip when you are in post make sure to set the audio ti mono

[@lelandclayton5462]

pretty cool.

[@DAVIDGREGORYKERR]

Next project should use a UDOO RYZEN Bolt V8 Maker Board SBC and associated UDOO Hats for different projects.(sorry for shouting)

So YoU RePlAcEd oNe DiAl WiTh AnOtHeR? kidding... lol.. 😅 Excellent explanation. I am studying for my general so found this video about DDS. Thanks . Well explained. 73 KC3TDE

Your project seems a clone of the picoSynthRF. That uses the raspberry pi pico. And a similar chip for DDS and it uses python on the pico and has an OLED screen...

Interesting, I'll have to take a look at their DDS IC and buffer amplifiers. It looks like they may be getting true dual channels, which would be nice.
