[GPS_Standard] unlocked receiver

[Graham Haddock]

This is a test to see if I can get a legitimate email past
the [incoming email] filters for qth.net [global positioning systems] 
standard list.. 

It keeps accusing me of trying
to sell stock on a "pump and dump" scheme and bouncing this email back to
me.  I think it is picking up the three and four letter abbreviations and
company names commonly used in discussing [global positioning systems] and
thinks they are stock abbreviations.  So here is the same email
without any [three letter abbreviations] or [company names] to see if it 
will let it through
this way.

Geoff:

Here is a link for a single chip [microprocessor sold by
MicroChip] decoder for the [National Marine
Electronics Association] character stream
coming out of a [your brand of] [global positioning systems] receiver
that will light a [light emitting diode] when the
[one-second] (or ten thousand per second] tick is valid.  It seems that 
Tommy, W1AUV had the same
concerns that you do.  His web site confirms that the [one pulse per 
second] tick comes
out of the [your brand of receiver], just like the [my brand of 
receiver], whether or not it is valid.

He also makes an [liquid crystal dislay] driver.

Poke around his web site.

Hi Graham,

Thanks for your reply, yes as I said I cannot find any info on the
status of either the 1pps or the 10kHz outputs on the Jupiter when
no signal is being received. Perhaps I could fire up the [global 
positioning systems] board
and see what happens.

Alternatively, I could add a simple switch to a) cut the power on
the Jupiter board or b) gate the 1pps signal. either should have
the desired effect.
