[Premium-Rx] Question on older premium receivers compared to “modern” technology.

[Kevin Greene Oceanos]

Help group:

Has modern DSP receiver design in part 97 ( or even milspec usage) really surpassed the high performance  designs of systems deployed in the last 1980’s up to today. 

I was thinking of the Rockwell collins HF805() or the TCI receivers such as the 8174 or even Harris receivers compared to modern Kenwood or Icom receivers.

It seems like the older units got very close to what is technically possible to what you can receive these days. With the QRM on HF, your only real advantage seems to really about more effective antenna systems for receiving. 

I really want to know. The challenge I have is if I should spend the effort to fix the older receivers I have or invest the money in more effective antenna systems. 

Thank you.
