Hi: Today had nothing on my plate and wanted to do a firmware update to MCU 5.50. I am using the latest utility dated back in early summer and it can't find anything on the site. However if I go to the FTP site manually I see the files MCU 5.50 and DSP 2.87, but would rather the utility do the work. 73 De Mike VE3YF http://www.ve3yf.com [http://www.ve3yf.com/]
