Hi folks, help needed I'm afraid.
I appear to have a problem with my FT980's PLL. I'm hoping its a stock fault and someone can point to the fault, but knowing my luck... Its hard to describe what its doing, but it seems to be either going out of lock every 1Khz or so, or its getting something in the loop div/N wrong in some way. It currently appears to be heat sensitive and intermittant but I hope to get further and more useful description of the symptoms later. As far as I can tell, the CPU is functioning correctly and is driving the display etc ok. Anyone care to describe how the thing works in simple terms? or know of a fairly straightforward test to determine the source of the problem. I have the users manual and the technical manual from http:\\www.mods.dk in PDF form but nothing there seems to be all that useful at present. I hope someone can help, all the best, Mike W -- |
