Mod for listening to satellites with doppler effect #33

Closed kaushleshchandel closed 9 months ago

kaushleshchandel commented 9 months ago

Hi, I like the project and want to create a mod. I am programmer and Ill start working on it.

To listen to satellites, you need to keep switching frequencies every minute, due to doppler effect. I am hoping to create a mod that lets you select a satellite, and its frequency. Then the radio automatically changes frequency every minute.

Is there anything like or similar to that? or a starting point that I can use to start programming something for this?

Thanks for the good work you are doing on the mods!!!

I am not sure if its possible, but can we change frequencies over serial port?

certainly possible but you will have to find someone else who is willing to put in the time to develop that

Thanks Matt.

I am a programmer. I have built a product for ham radio, called Boondock Echo. Check it out when you get time. It’s a ham radio recording, playback and transmit device. We are active with hackaday and we won 4th prize last year. We have built it as a product and about to run a crowd supply campaign.

I want to work on the feature. If you can point me in the right direction to get started, that would be great.

Thanks,

KC

In that case, just check out the various OEFW (open edition firmware) repos for the uv-k5. They contain a full C reimplementation of the original firmware and it is relatively easy to add arbitrary new features. I would suggest looking at the serial code and implementing the frequency set feature as an additional command. I believe there are also unused serial commands that can have this functionality added. https://github.com/DualTachyon/uv-k5-firmware
