Old Roberts radio into internet radio++?

Going to use a Raspberry Pi Zero W, a USB basic sound card and a little mono amp… plus a couple of isolated supplies. Maybe put a little bluetooth receiver in there also, so can just use it as a dumb speaker. Also some audio inputs on the back? The Pi bit will just stream my favourite internet radio station. To change station I’d just ssh into the radio, but got plans to use the existing tuning control to switch between a few.

Just going to get the Pi zero working with the sound card and amp at first.

What will you be using for the streaming part? Logging in via ssh seems like a hassle. You might consider making a small webpage using flask or something in python and make it accessible to your phone or anything with a browser and control it from there.

The Pi Zero W will be doing the streaming with SOX. Fair comment on ssh, although I find it as easy as accessing a web page with a browser. Could use some GPIO pins on the Pi Zero to hook up to the tuning knob on top. Just want the audio to work first though.

Already use Sox in my streaming to FM radio converter, it lets me play my old radios with online stations. This project just cuts out the FM radio bit.

I’m a bit old school so I find the command line infinitely easier to use than any GUI. Look at it this way: nobody has ever produced a graphical computer language that is as expressive as a textual one. Humans are really great at handling symbols, and text is the best medium for that.

Same, I’m an old school Unix admin and command line just makes sense to me, more so than point and click.

no quicker way to do a good job :wink:

Or a more gradual non recoverable one…

You know you can use the pi as an FM radio, don’t you (by modulating the clock frequency with audio) ?

Am already doing that on my other Pi, it’s really useful for those of us with old radio gear.

I have an old robersts as an ornament in the kitchen, i a somewhat loathed to butcher it… although in reality i can’t understand why they held a premium new as they are nothing special at all…

I just like the style, the outside seems to last better than the electronics on some models. Just didn’t fancy ordering NOS stuff only to have something else fail.

Did that the other day, cobbled together a usb power pack from salvaged 18650s too.

Are you restricted to a 20kHz sampling frequency or can this be higher?

I read up about it when building it the other week, but forget… The documentation about the program is here;

The sound quality is ok.
