What is the wire gauge on the Flex 6500 power cord?

not sure if this helps any but my new 6400M is very heavy i think #12 it is a monster but I could use it a little longer and not to hijack this post but it would be nice to have fuses in line the cable instead of inside the radio cabinet

Are there actual fuses inside the cabinet? I never heard of them before.

Of are you being facetious (ie - the pcb traces fusing)?

I agree that inline fusing is great and really easy to do. Fuse holder with pigtails and auto type fuses are readily available. Just split the cable, unless for some reason Flex does not suggest this.

I just hooked my 6600M up to my power supply today using #10/12 ring terminals and it was rather difficult to get all of the stranded wires into the crimp hole.   So, it may even be #10.

I think you suffer some voltage drop with inline fuses, it used to beacontinual discussion back when we wanted longer cords for our 5000s. Those who did this, did indeed suffer lower power output.

It really doesn't matter what wire gauge you use within reason (10-12-14), the wire length, or whether in-line fuses are added.  What matters is that at key-down full power output, your radio sees AT LEAST 13.8 volts at its power input.  For me, that means delivering about 14.1 volts when in receive, which is well within spec.  Many voltage supplies have enough adjustment that sufficient voltage can be delivered irrespective of wire gauge.  Making sure that sufficient voltage delivered at max xmt ensures efficient, full power output but, more importantly for me since I only use 45-50 watts output to drive an amp, keeping the right voltage maximizes linearity and conversely results in the best (lowest level) transmit IMD.

Thanks that is what I felt I picked up a 6300 which was never used with a flex knob and the power cord was missing. Radio is NEW as is the Flex knob so I need to make a power cord did not was to pull my 6500 out. When I check it out I will listvto sell.
