Using the latest version 1.2 build 01 and the AR-DV1 has the latest V1812A firmware installed.įirst thing I noticed was the USB driver that Butel includes (located in the program directory after installation) are WRONG ! They include the “ftdi” ones here and of course as all AR-DV1 owners know, it uses the Silicon Labs one. Only desired software to program the radio (not for any CAT operation). Purchased the full version of the ARC DV1 software “Basic Version”. We attempted to communicate directly with Gommert on this, but he gave no reply so will try here for answers and input.
