Spectrum Lab User's Manual Spectrum Lab User's Manual This „document“ is just a collection of all HTML files from Spectrum Lab's built-in help system. They were simply combined in a master document in OpenOffice (later LibreOffice), by means of 'including' the html pages as sub-documents. Unfortunately, the links between these sub-documents (which were once HTML pages heavily linking to each other, and to the 'index.htm' page) get broken in the OO document. This is the reason why all those helpful links don't work in the PDF you are currently reading. If you have a solution (i.e. how to convince OpenOffice / LibreOffice to get the hyperlinks working again, without having to edit zillions of links manually), please let me know.

  • PSK31: a New Radio-Teletype Mode

Coverage Policies are intended to provide guidance in interpreting certain standard Cigna benefit plans. Please note, the terms of a customer’s particular benefit plan document [Group Service Agreement, Evidence of Coverage, Certificate of Coverage, Summary Plan Description (SPD) or similar plan document] may differ significantly from the standard benefit plans upon which these Coverage Policies are based. For example, a customer’s benefit plan document may contain a specific exclusion related to a topic addressed in a Coverage Policy. In the event of a conflict, a customer’s benefit plan document always supersedes the information in the Coverage Policies. In the absence of a controlling federal or state coverage mandate, benefits are ultimately determined by the terms of the applicable benefit plan document. Coverage determinations in each specific instance require consideration of 1) the terms of the applicable benefit plan document in effect on the date of service; 2) any applicable laws/regulations; 3) any relevant collateral source materials including Coverage Policies and; 4) the specific facts of the particular situation. Coverage Policies relate exclusively to the administration of health benefit plans.

  • The Exam Corner #8
    THE EXAM CORNER #8 By Steve Weeks, AA8SW This is the last of three articles on the topic of emissions. This section deals with the rapidly-evolving subject of digital modes, and unfortunately that means that some of the questions (which were prepared in 2015) are a little outdated. In the 2019 revision, I’m sure that the examiners will update this material. In the meantime, we have to deal with the current question pool as we find it. Again, I will briefly discuss what you need to know about an aspect of that subject, then show you the only exam questions that could appear on that aspect, and follow with hints as to how you can remember the right answer. The correct answer is in bold. ● The digital modes represent a merger of computer and radio functions. Accordingly, computer terms such as “bits” are involved. A bit is a single binary digit that can have the value of 0 or 1, and when transmitted by radio using Frequency Shift Keying, where one frequency represents a 0 and another frequency represents a 1, they are called “mark” and “space”. G8C11 How are the two separate frequencies of a Frequency Shift Keyed (FSK) signal identified? A. Dot and Dash B. On and Off C. High and Low D. Mark and Space ● Like in a computer, where a character is typically represented by a byte (8 bits), digital characters are sent by radio as a series of bits – which may be a specific number of bits for each character, or a varying number, depending on the protocol.
