The COMM 2 radio is mislabeled in the ME as well as in the Comm menu as an ARC-222. The Blk 50 F-16 Circa 2007 as flown by the United States Air Force contains an ARC-210 UHF/VHF radio just like the two that the F/A-18C Hornet has. The ARC-222 is VHF capable only. This makes this particular portion of the module unrealistic as it hinders virtual pilots from utilizing multiple UHF frequencies. Also, I am aware that the throttle grip says UHF and VHF. This is due to the fact that the C" models used to contain an ARC-186 VHF radio. This was replaced by the ARC-210.
My source comes from my near decade long experience on this airframe as an Avionics Technician. I have included snip-its of my findings. If you need some documentation to back up my claims, I will happily upload my credentials and certifications.
