Anyone here programmed these Icom F420 radios. I cannot seem to get them to play in the 440 area. I have all the software and cables but sure am missing a step somewhere. I program a high and low freq such as 440 and 470. I try to set the pll voltage using this and can only get 7.75 volts no matter what. The freq display is flashing so I knowit is out of lock. I can go back to the original 413 mhz channel and the pll drops to 3.85 and locks right up. I have the 300 programming software but cannot find the directions for programming anywhere. I downloaded the manual for the johnson rig and followed that instructions but still not happening.
Any ideas? Got 4 nice radios I bought on here but just paper weights right now. Larry WA0VUS
