Seems you radios are probably -9's (400-430Mhz). They can be retuned up to around 450Mhz. There's a procedure discussed on the mods.dk website. You'll have to program several channels throughout the amateur band then use the service mode of the software to access the soft tuning tools. Not too difficult once you learn the procedure. When you're done it should function fine from about 420 to 450Mhz. Gary

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.
