***********************************************
Some Notes:
* At ATH, 38MHz riometer was installed for 120925-161025, though the sensitivity
was not sufficient to see CNA.
* At ATH, the riometer antenna cable and preamplifier was broken after June 21, 2023, due to animal attack. We will repair it as soon as possible (230915).
