Has anyone done mods to use the 5Watt PA on the lower VHF bands 6 and 2meters? The assembly instructions hint that is may work on those bands. The suggestion of substituting the IR510 for the RD15HVF1 I have done. I am about to embark on modification to improve the O/P above 28Mhz and wondered if anyone had already done mode to the kit. I am aware that the operation will be reduced below 28Mhz as a result. Any input from someone who has tried this would be appreciated.
