[time-nuts] Dual-bandwidth loop for VCO phase lock

[paul swed]

Crazy as this is I suspect I have the same article and though it may be
very useful on the costas loop I did not want to get tangled in a second
loop if I could avoid it.
Like you Perry the math gets touchy. But the circuit actually really get
tricky.
Regards
Paul.
