DSP radio covering AM-SW-FM frequency

It is not up-to-date topic but several one-chip DSP radio is available on market. These chips realises very wide band receiver (generally AM-SW-FM) without any conventional inductor and resonator but single chip controlled by I2C. Indeed I made several one before I joined hackaday.com and this time I made "summary" of it. It consists of KT0915 (DSP radio chip), ATmega328 (controller) and LiPo charging circuit. More details can be found at hackaday.io/pr... and MOREOVER parts kit will be sold at www.tindie.com... Don't miss it!!

Wow this is very interesting to see a single DSP chip as the radio on the pcb. Thanks for sharing this video! 👍

[@marjla]

Very interesting.Thanks for sharing.

Epic radio, I want one! How do I get one?

[@AdamEbelgccengineering]

Great, I missed my opportunity to build this myself. Because the dude has retired and does not offer no more of these kits.

Here is the current version. Several points are improved to the original!!

Dear You did it! I wan to asking you about this receiver. I need to receive NOAA19 (137.100MHz FM frequency) satellite signal. Have you trying to receive this frequency before ? Pleas share your experiance.

Good radio

[@SerjShvediuk]

please give links to the components of the device . Want to repeat the design. Yourself could not find on the marketplace. Thanks.

[@microwavemont]

This is, indeed, mystery. The chip KT0915 is available only at Akihabara, Tokyo. I've checked its availability but could not find even in aliexpress.

POKE the battery with a skewer for EXCITEMENT! XD
J/K dont do that, neat radio though.. Do they make thses with SSB options, I am not interested in commercial shortwave but rather HF ham radio
Also is it just a China thing for FM to drop under 88 MHz? I bought some Baofeng UV-B5 handheld 2-ways from China and they have FM receivers in them that drop down to like 76 MHz or so. nothing in the US operates that low on FM..

[@microwavemont]

Good point! but unfortunately none of single chip DSP radio support SSB reception. may be direct conversion (oscillator + mixer) would be better answer...!

Display?

[@microwavemont]

It's OLED.

Hello :) What kind of DSP chip do you use for this?

[@microwavemont]

Hello, it is KT0915, which data sheet can be seen at aitendo3.sakura.ne.jp/aitendo_data/product_img/ic/radio/KT0915%20/KT0915_datasheet_V022_aitendo.pdf
