My wife ordered the 6600M on 5/22/2017 and she received the shipping notice today. So it looks like FRS has shipped out all the Hamvention orders. I can't wait to use the radio. Thanks to all at FRS for putting in all the extra work to ship out the radios quickly.
I second Tom's motion! My 6600M shipped today via UPS overnight so I'll have it tomorrow for ARRL DX CW this weekend, thanks to Mike and Katie expediting my 6500 trade-in which arrived this week. I ordered my 6600M on 5/23/2017 and the May 18-20th 2017 Dayton Hamvention orders went out first. First class customer service!!!!
