[time-nuts] Couple of questions for Racal 1992 owners

[John Green]

Just acquired a used 1992 off eBay. Excellent, almost like new with manual
and even spare fuses. I noticed that the internal reference's waveform is
more like a nasty sawtooth than a nice sine wave. Is that normal? Also, when
I hook my GPSDO through a two way splitter and two different length cables
and measure phase, I get a +\- 3 LSD ambiguity. Is that about right?
