10MHz WWV Receiver Part 2

In this segment, I complete the 10 MHZ TRF and test it. I provides 40dB of gain but not at 10MHz!. I did not use the specified crystals. So I have ordered the specified units (10 and 5 MHZ) and will show the results in Part 3. Part 1 - I do not have any standards in the shop that are directly traceable to the NIST. One standard IS available to anyone that is able to receive one of the frequency signals broadcast by the NIST. I elected to build a 10 MHz receiver, with a very narrow bandwidth filter, NO heterodyning or detector. The output should be a repetitive signal at 10 MHz. I also have the parts for a 5 MHz receiver. These two receivers and post-amplifiers were designed by WD8DSB. These were described in a Feb 2018 QST article. Files: https://www.gswagner.com/WWVRecievers/
