Well I had the bright idea that I would simply rebuild my audio isolation box and add a relay to key the PTT circuit with the PI’s GPIO pins for digital modes since the IC-730 doesn’t have a traditional rig control.
OK so some functionality that I want to achieve is up and running. GREAT NEWS is the noise floor that’s plagued my station is now gone! From a S5/6 noise floor down to S1/2 let’s hope it stays that way!
Recently I purchased a PI4 to replace an ageing tower because of the noise floor it was creating on the 40m (7mhz) band. So far the PI has succeeded in reducing the noise floor from s5 to s1 here in the shack.
