I use JTDX for JT65, I use 25 watts for TX with my FT 450 this runs through the Yeasu SCU-17 cat interface. I also run MultiPSK with my SDR radio this is an SDPlay Mk2 this realy works well the antenna setup for it is a homebrew QFH for weather sat from the NOAA system. A diskcone for the other vhf bands, and a Jetfon Out-2 dipole for the HF bands. I have 3 Laptops one is linked to the FT 450 the other is dedicated to running the SDR radio. the other is for logging and other work.
