As I mentioned in a private message to you some time ago, the concept and even the design already exist, but it is much more complicated than at first sight and it involves much more than radio waves. If your desire is to have radio signals received, then a certain conversion has to be made by the device, as it is mainly designed to retrieve –information- from the future. It has also some other inconvenient aspects, one of them is that it takes quite some time to retrieve information from further away in the future, tat is – the further you want to retrieve information from, the longer it takes. As an example, if you want to retrieve information from 1 hour in the future, you would have to wait for maybe a few years. In other words, if you want to retrieve information from 1 hour in the future, you can not do it now (October-10-2020 at 21:00 retrieving from October-10-2020 – 22:00), you will be able to do so only about 2 years later for example (on October-10-2022 at 21:00 retrieving from October-10-2022 – 22:00). During all this time, the device is not allowed to stop, otherwise it “resets” and you must star all over again.
