Yaesu ADMS-VX8 programming kit by RT Systems (paid)
Recommended version Paid software — not hosted
Yaesu's ADMS-VX8 memory and settings programmer for the VX-8 series, sold by RT Systems with its USB-59 cable for US$49 (Mac version +US$15). Works with the VX-8, VX-8D, VX-8R, VX-8DR, VX-8E and VX-8DE; not the VX-8G.
Read before installing. Paid, licensed software: link only. Yaesu publishes no free VX-8DR software, and no user firmware update exists for the VX-8DR (Yaesu's VX-8DR page offers only the operating manual; the 2009-2010 APRS upgrade for the VX-8R was a paid service through Universal Radio). CHIRP (free) supports the VX-8DR.
