Narrative:

I was transporting government officials from lake havasu, az to yuma, az. Approximately 45 mi from yuma, I called yuma approach control and was given a transponder code. Approach notified me that I was in radar contact and to immediately turn to 270 degrees as I was inside the R-2306 complex. I complied with ATC and began xchking my navigation radios. I had preset the blythe VORTAC 150 degrees radial on my #2 obs, and the bard VORTAC 345 degrees radial on my #1 obs (HSI). My purpose in presenting these radials was to assist me in remaining clear of the R-2306 complex to the west. I was also referring to the circuit breaker-18 WAC chart. Yuma then told me I was clear and to resume my own navigation. After landing in yuma and conferring with my passenger, I learned that at least 1 and maybe 2 cellular phones were being used by my passenger. Both VOR receivers in the aircraft were signed off as being checked by the pxr-vot in feb 94 with zero error. I can only assume that the cellular phones could have affected my navigation radios. I recently read in the aviation safety journal about the problems with could arise from using portable electronic devices while in flight. I plan to distribute that article to all employees on my operation in order to alert them about the hazards of using portable computers and telephones in aircraft.
