Don Mimlitch,
Your email is most interesting. My GPS76 receiver shows PRN#35, which was
moved West from its position over the Atlantic, but no PRN#38 or #51. What
are the positions of these two WAAS satellites. How are you monitoring if
your 17HVS refuses acquisition?
The reason I am
TAPR is pleased to announce that the TADD-3 PPS distribution amplifier
kit is now available.
The TADD-3's primary use is to distribute 1 pulse-per-second signals
such as those obtained from GPS timing receivers, but it can work with
pulse signals up to at least 10MHz.
The TADD-3 provides six

You can drive the LED from the DCD line, but along with a series
resistor you need to be sure to include an extra steering diode in
series with the LED. LED's have absolutely no sense of humor about being
reverse biased above a volt or two. This might also affect your 1PPS
pulse accuracy.
Hal,
Certainly true. The UT+ is programmable so that you can disable the 1PPS
altogether, disable it if TRAIM fails, or disable it if the receiver is
not tracking at least one satellite. The default condition is for the
1PPS to be on all the time. Many systems require that the 1PPS stay on

Hi:
Awhile ago there was some discussion about the ICS525 and I finally got
a quote on their demo board it was $57 and 10 weeks. Well it's been
less than 10 weeks and I've made my own, with more features than the
stock version. There's been some delay getting all the stuff to do fine
