There has been some confusion (mainly on my part) about the hidden feature behind button number 5<\/strong>.<\/p>\n

Pressing and holding the number 5 will toggle the radio between 50 and 75 uS.<\/p>\n

But what, exactly, is this function?<\/p>\n

Thankfully, Eric Cottrell has the answer:<\/p>\n

“The 50\/75 uS setting is the FM De-emphasis<\/strong>. 75 uS in the US and 50 uS in Europe.”<\/p><\/blockquote>\n

Eric then pointed to a discussion about de-emphasis on DIY Audio’s website<\/a>.<\/p>\n

Many thanks, Eric, for clarifying this (and thanks to others SWLing Post readers who pointed this out in comments as well).<\/p>\n
