Tom: Thanks! Rob: your toolchain (to borrow a phrase) produces great
results. If I read the graphics right, you might be able to obtain some
outstanding results from the HAARP Research Campaign 29 Nov - 03 Dec

I’ve been monitoring the Doppler shift of WWV/H and CHU for a while now from my
location 100 km / 60 mi NW of Seattle.
The receiver is a QS1R, using an LTC2208 16 bit ADC, and the 125 MHz clock is
provided by a Bodnar GPSDO. A Wellbrook ALA1530S+ loop antenna provides good
coverage for the

Did you update this TS-2100 with HEOL Design’s replacement GPS receiver?
Several time-nuts participants (and some scientific organizations) performed
this update/upgrade (including me), replacing the obsolete TrimbleACE III GPS
receiver.
Dana,
As described in the following HP GPS splitter the isolation is > 40dB.

I use one of these 8-channel splitters.
I had a bad experience using a passive splitter of the minicircuits in the
10MHz distribution in my lab.
Hi,
I am using Mini-Circuits ZN4PD1-50+. They are about 30dB in the GPS
frequency band. I hang 4 receivers each off three of these mixing Motorola,
Ublox, Trimble and Navspark and never had an issue.

I want to run about 4 separate GPS units of disparate
manufacture from a single antenna. My plan is to
provide power for the antenna via a bias tee (power
inserter) at the bottom end of the antenna's cable, then
use an isolating splitter on the receiver side of the bias
tee to split to the
