Programmed via software and keypad. Had some difficulty with inability to Read from radio so just input and did a Write. Worked first try on one and had to reboot laptop to Write to 2nd HT. Seemed like all was good. Programmed other items via keypad. Took both out in the field for testing using Wouxun 805G, Kenwood 3170. One of the 76 worked fine, the other will TX but would not RX against any of the other radios. Set SQ to 1, made sure CTCSS were identical and made several attempts with no RX. If you have a suggestion I’m wide open. I’ll play with it at home today but if I can't make it work will have to see about returning. Fortunately, I bought them here so am confident I'll get taken care of. Honestly, these being my first dual-band HT, I’m not a fan and prefer the simplicity of the 805G/3170 using GMRS only. For me, it's a must to Lock the keypad whenever in the field.
