Sorry you're having trouble, but I'm glad to know that it wasn't just me. At least you only spent several hours on it, I just finished days of messing with this and about a half-dozen back and forth emails with Gary at Elecraft.
There is a v1.6 firmware that I finally got to install, even though the downloader program never "found" the KRC2. It took about three tries to get it to take and then the configuration program would find the KRC2 and allow reconfiguration, *if* I used a computer with a real serial port. I could load the firmware with a USB->Serial adapter, but couldn't reconfigure the KRC2 with the same adapter. Go figure. It can be be made to work but it's waaaay too difficult.

I've tried setting 4800 bps, 8 bits, no parity, 1 stop, no handshaking in the COM port property panel under the device manager, as well as disabling the UART TX/RX FIFO. Nothing seems to help. I've spent several hours tinkering with this, and have not been able to figure out why the downloader can talk to the KRC2, and the config utility can report the firmware version, but then balks at any further communication (attempted configuration downloads fail, as well). I've also tried pulling all the RS-232-related jumpers except W9 and W10 (RxD and TxD) but it didn't seem to make any difference. Of course, the D/L switch is set in the proper position. Any ideas? I'm at wit's end, and any help would be appreciated. 73, -- Dave, N8SBE ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
