You want to drive the RTC with an external PPS to get time/date into an
Arduino?
Why not feed the PPS to the Arduino and have it compute date and time?
It is really not that hard to count seconds. You don't really need an
external chip to

I for one would insist on complete situational awareness at all times.
The alternative is being LOST. That can be bad for one's health.
That is not the same as not wanting to be FOUND.

You also get direction, so for a navigation system, you can figure out
where you are.
I'm still missing the big picture.
If I'm working off direction, why are pulsars interesting? Why radio vs
optical?

Hi,
Some Qs for someone with 5071A experience.
I have picked up a cheapo second hand 5071A and would like to know what tube I
have and what remaining life I might expect.
It locked in about 10-15 mins after I applied power for the first time this
morning.
the box s/n is 3249A00498 and the

Hi Mike,
Cs tubes with S are standard-performance; tubes with H are
high-performance. You can get that from the tube label, or from the front
panel S/N. Don't trust the black dot on the rear of the instrument: frames

If I am reading your screen shots correctly the 01:51:57 UTC shot is before the
antenna move and the 14:02:03 one after the move.
HOWEVER, both shots show the same saved position. That is certainly not going
to be optimal. You

The purpose is the flip the pulse. The MAX 232 chip flips the logic
once which works fine for the data but you need to flip the control
lines (maybe if the GPS reciever did not already do this for
