i compare the FT DX with a IC7700, Flex 5000, Elecraft K3 and the HPSDR.
Belive me i think it is the best of all the above Trancievers. I tested all for more then a year. Im 100% satisveid wit the Yaesu. The reciever petformance is realy outstanding. I use it mostly in SSB with the both black boxes from W2IHY with a Rhode NT1A Mikro. With the bandwith of around 4 Khz and the flexibility to switch it from 2.4 to 4 Khz i love the rig. It is a real ESSB rig with all what is needed in a shack. I will give it 6 points from five points. hi hi ...
It is the best trx i use until now. I sold my K3 and the Flex and Icom.
I use the LP Pan to see the spectrum. Works great!
