The TS590 is quite an upgrade from the ICOM 735. Noise rejection and filter options allow many signals impossible to hear on the IC-735 come up out of the noise.
With the Buddipole dipole up just 12 to 15 feet, directionality is not great, but on very weak stations an "ARM" rotator helps get my signal out.
I doubt I could have completed the ARRL Diamond DXCC Challenge without the station upgrade.
