BSF is a time and frequency station in Taiwan, operates on 77.5 kHz, 5 MHz, and 15 MHz. Their signal happened to make it Germany late one evening in 1988, and I reached out to them with a reception report. They replied with this QSL card.

BPM, like its sister stations WWV, WWVH, etc. can be heard throughout the world if conditions are good. I heard their 10 MHz signal in Maryland and sent off a report. This QSL card was their response.

YVTO was a time signal station transmitting the legal time for Venezuela on 6,100 kHz right in the middle of the 49 Meter Band. It was operated by the Venezuelan Ministry of Defense Naval Observatory “Juan Manuel Cagigal.” They replied with this very official looking QSL card for my 1985 reception report.

YS3 in Nauen was a time and frequency station in East Germany (before 1989). I heard them in 1986 when we lived in Maryland and they replied with the QSL folder below. Although they did not explicitly state I heard them, I have to believe their intent. So I am counting this.

The National Research Council (NRC) or Conseil national de recherches Canada (CNRC) operates radio station CHU on three frequencies (3330 kHz, 7850 kHz, and 14670 kHz) to maintain official time for Canada. They can be heard on at least one of the frequencies 24 hours per day depending on propagation. They issued the QSL cards seen below for my reception reports. CHU’s English language website is at https://www.nrc-cnrc.gc.ca/eng/services/time/short_wave.html

This is a QSL for WWVB 60kHz for a 2008 reception. If you own an “atomic clock” or a “radio-controlled clock” and live in North America, you picked up this station when your clock reset to the current time. Yes, this is the station which is received by these clocks when they reset their time It is done by a simple code. I would assume that they would not send a QSL verification for a clock resetting. I received the station on my SDR-IQ (Software Defined Radio) on its waterfall display mode. The display came out nice and clearly showed that I was picking them up.

WWVH is the time and frequency sister station to WWV in Fort Collins, Colorado. The 5 MHz transmission can be heard here on the East Coast of North America through WWV just before sunrise. Prior to July 1972, WWVH had been broadcasting from the Island of Maui and since then on the Island of Kauai. So there are technically two different WWVH’s. I heard they had a new QSL card so I sent a report and this is what they sent.

WWVH broadcast from Maui, Hawaii from 22 November 1941 to July 1971, when it moved to its current location near Kekaha on the Island of Kauai, Hawaii. WWVH did not broadcast voice announcements like its sister station WWV in Fort Collins until July 1964.

The station sent the QSL card below for my 1970 reception report.

OMA was the time and frequency station for Czechoslovakia. It was possible to hear them in Maryland in the 1980’s on 3170 kHz (OLB5) when conditions were good. It was operated by the Czechoslovak Academy of Sciences’ Astronomical Institute in Prague.

They send this QSL card for my reception report.

HLA is (or was) a standard time and frequency radio station operated by the Korea Standards Research Institute’s Time and Frequency Laboratory in Daedeok (Taedŏk) Science Town (대덕연구단지) near the city of Daejeon (대전 or Taejŏn). HLA first came on the air on 5 MHz in 1984. I heard a rumor that they were no longer on the air. However, there is a reported logging of them in 2018. I have not been able to verify it either way. Listening to remote SDR receivers in the East Asia area, including Korea have so far proven negative.

They responded to my 1991 reception report with the QSL card displayed below. Additionally, I took a day trip and drove down to the station and was treated to a fine tour of their facilities.
