"Clif Holland" wrote in message ... The problem is to get the 10-20w out of the radio you may have to shove 100w into the filter, and that's what hurts. You need to monitor the current drawn to determine if there is a possibility of damage. Give this man a cigar because he's today's exclusive winner on 21! The problem is that most modern hams today don't have a clue about what you're talking about because most modern hams don't understand the theory behind bandpass filtration, especially in their own Riceboxes. They actually believe the radios will go from DC to Daylight once opened. I believe this is the reason why Yaesu, Kenwood, and Icom haven't publicly released the mods to these radios (other than to MARS/CAP members) because these companies know damn well that they'll be performing a slue of warranty repairs on the lot because some jack ass will actually try to use his radio on the commercial AM broadcast band. |

So far, Ten Tec is the only one, I know of, offering specifics on getting on 60 meters. For their rigs, it's a simple software download. Bob k5qwg |

You need to monitor the current drawn to determine if there is a possibility of damage. Though I can't speak for the 746Pro I can firmly state that the BP filter for the 746 DOES cover the 60 meter segment. It is spec'd for 4.0 to 8.0 MHz. Measurements in the lab showed no difference between the current draw vs output power between 40 and 60 Meters. Assuming your antenna presents a good match, you should be confident that the 746 will perform just fine and within specs when modified for 60 meter operation. 73 Dave Give this man a cigar because he's today's exclusive winner on 21!
