They code what they want to.
In this case, he wanted "bells and whistles(as you call it)" and he wanted to make it that way.
If you want something different, make it yourself how you want it to be - or pay him to add in features you want.
Well aren't you an Einstein today. Simon Brown and others have made awesome SDR software. And they work with a plethora od SDR radios.
The front end for dongle, Airspy, etc radios I suspect are "canned" to implement into these applications.
Being the true scholar and philanthropist you seem to air yourself as . Should realize that I am not a programmer.
But smart enough to review the different .dll drivers and see that there is a basic standard with similarities for supported and non-supported radios. And. FYI not a single person I've directly or indirectly asked involved with trunking decoders has acted interested and enthusiastic.
It's been mentioned before. Why did Airspy remove the ability to use extio .dll drivers from their "free" software. And when a workaround was discovered to make the drivers usable again. They had a you-know-what fit. And removed the ability immediately. Plus threatened the developer for what should be open-source code with legal proceedings.
Another cockamamie and weak reason is they do not have the actual radio in their possession to work with.
As if they have never heard of RDP to access a pc with working software for a radio such as the Icom IC-R8600 and others that allow use of their own and third party SDR software.
Not a single person who put's these Lego kits together has responded positively. An "I'd like to look into what is involved", "Hey, good idea....sounds cool". I'd pay. Not thousands. Not even hundreds. Look at DSD+ Fastlane. Not a single response from them. And stupid me expecting the cash spent would let me use my radio with the subscription that I paid for a lifetime sub. Others are drooling for a digital decoder that trunks and works with their radio's. Look at good old fldigi. Easy to get it working with a pile of different radios with some setup tweaks.
Sir. I hope that satisfies your theory of general relativity for the next time you get all smarmy with Elon and burn a few doobs.
