Flex Reinvents Half of the National Select-O-Ject

Jim Bryce W5HFS

Kudos to FlexRadio for reinventing half of the Select-O-Ject that National delivered in the 1950's as a standalone box and as an integrated feature of my NC-125 from 1952. The "new" Flex Audio Peaking Filter (APF) now appears over 60 years later in SmartSDR 1.1 providing the "Select" function by peaking a narrow audio band. Of course Flex previously reinvented the "Ject"  function in PowerSDR with tunable narrow audio notches. Have I missed that feature in SmartSDR? I anxiously await Flex's "new" quenched spark gap download for the FPGA.  :-)

I like the ANF on the 6500, but I really miss the TNF on PowerSDR.  It was very effective and didn't color the receive audio at all.  ANF did, even though it was an effective notch.

I hope TNF is on the back burner, or middle burner at FRS.  It is a great feature.

It is on the Roadmap for SmartSDR v1.3

Wonderful!  I thought I may have seen it, but my downloaded copy of the roadmap is on my other computer.  Thanks!
