Ron, I've had my 590 for a year and a half and I'm still learning the various uses of all those buttons. I have some of the same questions as you, but I don't use a number of the buttons, because they seem to relate to modes and functions that don't interest me. With all that, I love the rig, and it will probably be the last rig I ever buy. 73, Gale [log in to unmask] ----- Original Message ----- From: "Dr. Ronald E.

I would love to have a TS-590, but I've read the manual, and it sounds soooooooo complicated. If you press a button it does one thing; press it again, and it does the opposite, and if you press and hold it for 2 seconds, it does something entirely differently. Then, what is this USB data and LSB data stuff? I've been inactive for a few years, and I feel like I'm in a totally different world of ham radio. Do you people really fully understand and use all of the buttons, features and functions on rigs like the TS-590 and the TM-V71A? Ron, K8HSY 73, Gale [log in to unmask]
