If it comes to DSP or SDR one line of code wont get you too far ?
SDR is a amazing field and you can do a lot of things which is why the technology has been found its way into both military and commercial applications , but there is still plenty of old fashioned RF stuff in front of the ADC even though the antenna moves closer and closer to the ADC !

Absolutely agree with Dave - how any of the buiders canwrite a line of code, that might just replace a piece of hardware or make it easier to use ??
Quoting Lothar baier <Lothar@...>:
They might be building stuff but nothing that has to do with RF ,
maybe microcontrollers robots and drones ....
As far as HAM RADIO goes ( and I am a HAM btw ) 'giving them out "
is about correct ...... if I compare the questions I had to answer
back in 85 when I got my first license in germany and the questions
now ....... well I am not going there but the german DARC pushed more
and more to make things easier to bring more people to the hobby and
it shows

Dave with all due respect , I been selling microwave parts at local

license statistics mean nothing , there might be more hams than 10

No, the kids aren't buying microwave parts at hamfests. This is
what I was meant when I said "it is DIFFERENT now". They are buying
parts from Adafruit, SparkFun, and Amazon, and hundreds of other
places. And they are building stuff like crazy.
And yes, ham radio has changed too. I was first licensed in the
early 1980s; I've watched it changed quite a lot over the years. A
lot of the inventiveness has moved to software, where even people with
no money or no mobility can be creative. Have you seen any of these
new-fangled digital modes? Some of them are downright amazing.
License statistics mean quite a bit; they're not giving them out to
people who haven't asked for them.
It is not so bleak as you say. Actually it's not bleak at all.
It is wholly unreasonable to assume that nothing in as forward-looking
a field as this one will never change, and then complain when it does.
...And I can analyze those signals with my 89441A!
