This is one of my all time favorite QSLs. One evening while at school at BYU in Provo, I happened to tune my Realistic TRF to the upper end of the band around 1622 kHz and heard something that sounded like a meeting. After listening to it for a while, I heard mentions of Big Bear Lake. So, on a whim, I wrote a tentative reception report to radio station KBBV in Big Bear Lake. After a few days, I received this letter in the mail. I don’t think that there are any stations licensed for this type of service on this frequency because it is in the middle of the X-Band (1610-1700 kHz), which is now occupied with regular broadcast stations.
I am not sure which category this station belongs in. It is a type of utility station I guess, but it is a broadcaster of sorts also. If you know exactly how these stations work beyond the explanation by Mr. Vern Thompson, please let me know. I am curious.
