The 90 metre band \u2013 Then and Now<\/h1>\n

by Dan Greenall<\/strong><\/p>\n

A few decades ago, the 90 metre shortwave broadcast band used to be full of interesting and challenging-to-hear DX signals. In the 1974 edition of The Complete Shortwave Listener\u2019s Handbook, author Hank Bennett reports on what you might expect to hear on these frequencies. There is a copy of this book on the Internet Archive.\u00a0 Here is a link to that specific page<\/a>.<\/p>\n

Also, this sample page from White\u2019s Radio Log in the 1972 Communications World magazine shows a number of stations that could be logged in 90 metre band.<\/p>\n

\"\"<\/a>Here are a few links to recordings from my personal collection that have survived through the many years.\u00a0 These were all made between 3200 and 3400 kHz from my listening post in southern Ontario, Canada.<\/p>\n

Today, it seems that only a handful of stations can be found broadcasting in the 90 metre band.\u00a0 These would include WWCR in Nashville, the Voice of Indonesia, KCBS Pyongyang and Radio Mosoj Chaski in Cochabamba, Bolivia.\u00a0 As well, the Canadian time signal station CHU still continues to use 3330 kHz.<\/p>\n

A recent recording of Mosoj Chaski Radio, a Christian broadcaster logged using a remote SDR in Lima, Peru, is presented here.<\/p>\nhttps:\/\/swling.com\/blog\/wp-content\/uploads\/2025\/10\/Radio-Mosoj-Chaski-Cochabamba-Bolivia-via-200.123.27.181_2025-08-28T00_01_55Z_3310.00_am.mp3<\/a><\/audio>\n

Although not in English, listen carefully and you can hear them give their frequency of 3310 kHz in the 90 metre band as well as their location of Cochabamba, Bolivia.<\/p>\n","protected":false},"excerpt":{"rendered":"
