UK-based SOTABEAMS has just released its new low pass filter kit. Low pass filters are an essential part of transmitters and also have applications in receivers.
According to http://www.southgatearc.org,
“The kit allows one of two filters to be selected and also incorporates a “bypass” mode. It has been designed to complement the WSPRlite Classic HF antenna testing system. To give users the most flexibility, the filter components are available separately to allow filters from 160 m through to 10 m to be constructed.”
“The kit has an optional aluminium case, that allows it to be finished to a high standard.”
For detailed information on the kit and how it can help with WSPR operations, please click the link at the top of this article.
