All, I am working on a TS-2000 here (SN starts with 303). The primary issue at the moment is I am not getting the rig to communicate with a computer through a USB to serial adapter now. It did and it took the software update from 1.08 to 1.12 fine. That is where things went south. For reference also - the software updates in the revision history or downloads page on Kenwood's site said the newer software includes all previous updates. So I assumed the versions did not need to be stepped. After the 1.12 software update I did a hard reset then loaded the memory channel/menu image back in. The rig would not work properly. It powered up fine but would not take the PTT from an external mic. I tried the Send button and it locked in to transmit and would not unkey. So I turned the rig off. After that I tried to back-date the firmware to 1.08. I noticed in the dialogue boxes in the firmware writing software after the first step of connecting to the rig with the power on and the switch inside the case off it does not state to turn off the rig, just to remove power. So I pulled the cable while the rig was ON (which turned it off), then moved the internal switch to the programming/on position, then plugged the power cable back in. The rig powered up. I think this is part of the problem with the rig now - it powered up with the programming switch in the ON position and I don't think it is supposed to. Anywho, I tried to continue with the firmware flash back to 1.08 but it would not take - the com port communication would not reconnect. I put the switch back to the normal/off position (with the rig off/unplugged) and performed a couple hard resets. I also tried bumping the baud rate to 19,200 from the standard 9600. No luck. At this point I can not re-establish communication through the serial port. That, I believe, is the primary issue. The secondary issue that I was in the process of working through was why the rig was acting strange on 1.12. What I would like to do is get the rig back to 1.08 so I am back where I started - but I can't get there because I can't communicate with the rig via the com port.... So the com port issue trumps all else at the moment. For the record, I backed up everything from the memory control program as well as the service software. I have tried, likewise, to reflash the memory channels/menu items back in to the rig from both software programs as well - same issue - no com port communication with the radio. This rig does have the voice announcer option in it. When I got to 1.12 it was working. Then in the issues I've had since the voice announcing has not worked (I have not tried to find any settings for it, on/off, volume, etc yet, though). Ideas?
