Thank you, I am glad that it was well received.
Most of it I got on eBay. Buyer Beware. Twice I ordered and they did not have the product in stock. I insisted they refund the money and one took two weeks before they did. Stay alert.
The following was from eBay
The GPSDO https://www.ebay.com/itm/165475429558
PLL-GPSDO GPS BG7TBL Tame Disciplined Clock Sine Wave GPS Receiver 10M 1PPS Green #US
The place I bought the Signal Generator is sold out but here are two links from eBay.
1Hz-8GHz Wideband Signal Generator w/ Make-Break Modulation + Power Adapter - US
The Frequency Counter was out of China and took weeks to get here.

I will most likely get a Distribution amplifier to send the signal to many systems from the same GPSDO.
10MHz Distribution amplifier OCXO frequency standard 8 port output
The person that made the riser card is on eBay as well.
Liquid Tin to coat the copper on the riser card from Amazon.
The last item that I did not discuss:
TL431 voltage reference board TL431 voltage source for calibrating multimeter. So if you would like to check your multimeter, this is a very good tool.
This is a very accuracy source voltage reference for ~2.5, 5 and 10 volts on one board and some high precision resistors and capacitors on another.
I have tested the voltages to the hundreth of a volt and they were spot on with my Fluke 8060A down to the hundredth of a volt. The resistances look to be very accurate as well.
I do not have an accurate way to test capacitance.
This is an ok attenuator to about 45db and it does the job I need. I saw a review and the test results and it was not great. It did not go to 60db as stated but I do not have a great way to test it.
I am sure it would help in a fox hunt.

One service monitor was a Wavetek CT Systems Model 2100 from 1989 and the other was a Motorola R-2200 A built in 1984.
Have a great day,
