Re: TS-790 / TS-2000 comparison



Freeman,

I used a TS790 for about 10 years and now have the TS2000. The ARRL Lab
shows both rigs have about the same sensitivity, or about -140dbm on both
432 and 144mhz using 500hz bandwidth. I guess the sensitivity comparison
would be fair when both rigs were new out of the box -- fatigue may have
taken it's toll on the older TS790 : ).

73, Tony KT2Q
