Lady Heather calendar functions


Yes,  Lady Heather has some rather extensive calendar functions built in,  including a list of common
(and not so common) holidays.  If the file heather.cal is found,  it uses that file for the holidays...
you can add your own or delete some.   Otherwise it uses the built in list.   I don't think John's latest
distribution has the .CAL file...  

The calendar file can handle fixed days,  days like the first/last Thursday of a given month,  and some
computable religious holidays (mostly Christian, Jewish, Muslim).  Also start of the  seasons,
 Chinese New Year, etc.  Even calculates the moon phase and shows it in the watch display.

It can also display dates in several different calendars (including Aztec, Mayan, Druid, Indian,
 Persian,  Islamic,  Jewish,  and a bunch of others).  Also can display sidereal time.

Also has alarm clock,  egg timer,  chiming clock,  singing clock functions.  A lot of documentation
is in the comments at the start of the file heather.cpp

Yep, it's there.

Parenthetically, the TCP test-mule Thunderbolt will be down for a few days,
in case anyone tries to access it.   Should be back up by Thursday night.

Re: Lady Heather calendar functions

Hi John:

Are you the one to ask about an optional plot?
The GPS satellite orbits are based on sidereal time so that they have 
repeating ground tracks.
If the satellite in view plot was in sidereal time then for a fixed 
antenna position the plots would not change.
This might allow a better way of selecting which satellites the receiver 
uses.

Have Fun,

That'd be Mark's department.  I just use it to impress visitors with the
nifty graphics!

HP3336B available

I have an HP 3336B Synthesizer/Level Generator that I no longer need.  It is
very clean, panel is good, all functions work as designed.  NIST-traceable
calibration is good through October 25, 2011.  Photos on request.

I cannot offer a warranty on a piece of gear of this age but it has never
given me any trouble.

Best offer over $500, plus shipping from Orlando, FL.

Contact me at omniryx@... if interested.

Not quite. The pattern does not perfectly meat up on orbit-for-orbit if 
you plot it on earth.

It will shift slightly for every orbit. It takes a year to match up.

Symmetricom board - please help with information

I've been given a very interesting board made by Symmetricom. For photos
and details, see:

http://www.qsl.net/z/zl1bpu/PROJ/Symm.htm

The board clearly has all the ingredients of a GPSDO - nice OCXO, GPS
receiver, 10MHz and 1pps outputs, TCXOs and other outputs. The OCXO has
SPI controlled VCO input.

However, the power connections and communications aspects are far from
normal, and I would like to hear from anyone who can tell me more - I'd
like to make use of the unit if I can. I would particularly like to
know:

	* What it does
	* What the connector pinouts are
	* How I can power it up
	* How I can talk to it

All the details I have and some really clear photos are on the web page
referred to above.

I found that for some reason the links to the high res photos don't work
this morning. If they don't work for you, - try:

Lady Heather Question

I've been running Lady Heather for some months now.  I've always been 
puzzled by one characteristic of the graphs.  If I use a view setting of 
anything other than 1 sec. per division, the oscillator graph in 
particular, 'runs wild'.  Spikes appear and disappear.  From second to 
second the sdv value can swing up and down by 10 or 20 ppt or more.  The 
ADEV values reported by Lady Heather are stable at 1.x e-8  <at>  1 sec. and 
1.x e-12  <at>  10K sec. through this.  My ability to measure ADEV at low Tau 
values is not great, but I'm getting numbers in the e-12 range for Tau = 
1-10 seconds which suggests that the Osc isn't all that bad.

Lady Heather Version 3.0; Jan. 15 - 2011.
Autoscaling of the graphs is disabled.
Time Constant, Damping, & Gain are at default
Satellite constellation is stable.  Right now it happens to be 5 satellites.

What's going on?

Thanks,
Ed
