Here is another old rig interfaced to Ham Radio Deluxe. It may not get better than this because I have read that this radio from 1976 is the oldest ham rig with a computer interface on the accessory jack.
This video shows the settings for transmit in BPSK31 with ICOM IC-7400, the interface CG Antenna SB-2000, the software Ham Radio Deluxe 5 and Digital Master 780. I’ve realized this video for my friend DF3JR.
Nice job…
