[R-390] HP 3586 Problem

[Bob Camp]

Hi

Haven't had the problem on the 3586, but I have had it on similar HP gear. Typically it's the VCO that no longer will pull to the end of it's range that matches up with "low end".  Depending on weather they did high side injection or low, that's either the high or the low end of the VCO range.
