Lets see, started with FT221, then FT 225 RD, then FT757 GX2, FT 847 with Collins filters, FT 100, FT2000-D, Ft 991A, no problems.
Every brand had their lemons, service here is good Yaesy repair shop 40 miles from me.
Perfect sevice so I'm good with them.
3 year warranty on the FT991A.
Though no other of my transceivers ever neded that in fact im running the fT847 that is 23 years old now at this moment.
