VFO and questions for builders.

 

Andy and all,

? ? ? ? ? ? ? ? ? ? ? ?I was wondering if there were plans to produce some VFO boards? If not what is everyone planning on using. I have seen an (AK2B) design with a Si5351 chip utilizing the Uno but controlling BPF's and LPF's are where I am falling short and I am not understanding how I could accomplish that.

Any insight would be greatly appreciated and most welcome. ?Ian K3HQL?
 

Hi Ian

I thought about doing another run of the VFO PCB's but decided against it.

There are many open source Arduino based options available using the Si5351 or Si570 and being open sourced means the code can be modified to incorporate user specific functions etc.

The original VFO I developed was based on a custom firmware chip supplied by SDRKits but unfortunately the code was not open source or made available to me.

I do have some code for the Si5351 which includes band switching but I need to test it and draft up a PCB which I will do once I have finished re-doing the LPF module.

Keep an eye on the group...

Regards

Andy de G6LBQ

Thanks Andy,
? ? ? ? ? ? ? ? ? ? ?The VFO looked like a real nice piece of kit. Though if you have plans for a pcb for a Si 5351 based VFO I will wait and go with that.?

Thanks again for all your efforts. They are very much appreciated. ? Ian K3HQL
