Kuntur is a 690 GHz receiver offered for the first time to the JCMT community in collaboration with the Large Latin American Millimeter Array (LLAMA). Kuntur is a sideband-separating (2SB), dual-polarization receiver, with an observable sky frequency of range approximately 609 \u2014 715 GHz (default IF 5.5 GHz). When installed, the instrument replaces the \u0100weoweo cartridge in the N\u0101makanui receiver. \u02bb\u0100weoweo will be re-installed in this position in mid-May 2026, in place of Kuntur.<\/p>\n<p dir=\"ltr\">\u02bbAla\u02bbihi is a dual-polarization, single-sideband (SSB) receiver, operating in upper sideband (USB) only, with a LO frequency range 80.0 to 88.5 GHz. This corresponds to a sky frequency of approximately 86.0 to 94.5 GHz given an IF of 6 GHz. The instrument&#8217;s performance for different IF values (e.g., 7 GHz) is under ongoing characterization. The Ala\u02bbihi receiver is being offered to the JCMT PI community for the first time.<\/p>\n<p dir=\"ltr\">For further information, please visit the JCMT instruments web page:<\/p>\n<p dir=\"ltr\"><a href=\"https:\/\/www.eaobservatory.org\/jcmt\/instrumentation\/heterodyne\/\" target=\"_blank\" rel=\"noopener\" data-saferedirecturl=\"https:\/\/www.google.com\/url?q=https:\/\/www.eaobservatory.org\/jcmt\/instrumentation\/heterodyne\/&amp;source=gmail&amp;ust=1762898801495000&amp;usg=AOvVaw352MxRQGxBtSnJPmvWapzC\">https:\/\/www.eaobservatory.org\/<wbr \/>jcmt\/instrumentation\/<wbr \/>heterodyne\/<\/a><\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">For information about PI eligibility and the Expanding Partner Program, please see:<\/p>\n<p dir=\"ltr\"><a href=\"https:\/\/www.eaobservatory.org\/jcmt\/proposals\/eao_eligibility\/\" target=\"_blank\" rel=\"noopener\" data-saferedirecturl=\"https:\/\/www.google.com\/url?q=https:\/\/www.eaobservatory.org\/jcmt\/proposals\/eao_eligibility\/&amp;source=gmail&amp;ust=1762898801495000&amp;usg=AOvVaw3Xe8q9U_t-rolpdnWo_P3v\">https:\/\/www.eaobservatory.org\/<wbr \/>jcmt\/proposals\/eao_<wbr \/>eligibility\/<\/a><\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">If this is your first time using Hedwig, you should use the \u2018Log in\u2019 button to generate an account.
