I have built one and can say it is very nice, I would like to see ozqrp release the code so it can be modified for special needs, but for now I will use it for a new BitX60.

Thanks Peter

I can think of several applications for a VFO of that size and versatility. It would ideal for in a BITX transceiver since the fixed output can be used for the BFO and the tunable output used as the VFO. This could turn a 20m BITX xcvr into a rig for any desired HF band; possibly even a 6m xcvr.
Another use might be found as an antenna sweep analyser provided one can modify the code within the microcontoller.
When I get my hands on one of these I'd like to install it within a PSK31 transceiver that I built for 80m. The plan is to get it functioning well on 80m before tackling the other bands.

Do yoy know some 0,96: oled display cb band dds vfo with 25/27mhz si5351 board selection simply by grounding arduino's pin?

[@shroomskunk]

Would this be suitable to convert an fm cb type radio by removing the Crystal of the radio and replacing it with this unit?

[@vk3ye]

Possibly but you really need to know what you're doing and preferably have a circuit for the CB. Achieving the frequency modulating may be difficult.

[@RobMacKendrick]

So I could swap this into a rockbound rig and get bandspread on rx and tx, is that accurate?

[@vk3ye]

Yes, if it's connected to the right part of the circuit you will get frequency agility.

@@vk3ye TNX OM!

[@Gw0wvl]

That looks a Very tidy piece of Kit .. Thanks Peter ... de Marc Gw0wvl.

[@Guns_N_Gears]

Link is broken

[@vk3ye]

Oz QRP has retired so kits are no longer available.

[@bazzaar1869]

This project, like hundreds of others on the web and UA-cam, this is incorrectly labelled "DDS". It isnt. Thank you.

You really need to get rid of your potato camera

[@smallenginedude71]

not everybody has the money for a nice camera. besides it still does 720p which is perfectly fine

[@electrocity2000]

It may show as being in 720p, but I can assure you the quality of the video is definitely not 720p HD.
