HPR4382: Understanding Antenna Gain and the Decibel scale

לפני 16 hours

—

This show has been flagged as Clean by the host. Power Measurement and Antenna Gain HPR show by Paulj, May 2025. 1.0 Power expressed in dB (also written as dBW) Power P dB = 10 . log 10 P Where P is the power expressed in Watts. 2.0 Power expressed in dBm Power P dB = 10 . log 10 P Where P is the power expressed in milliwatts. 1W = 1000mW Power P dBm = 10 . log 10 1000mW Power P dBm = 30 dBm so: 0 dB = 30 dBm 3.0 Power expressed relative to an isotropic antenna - dBi An Isotropic antenna is an theoretical ideal antenna which radiates equally in all directions. Imagine the antenna is at the centre of a sphere, the signal strength at the surface of the sphere is equal at all points. The gain of an isotropic antenna is defined as 1, meaning: 10 dB = 10 dBi 4.0 Power expressed relative to a half wave dipole antenna - dBd The simplest practical antenna is a half wave dipole antenna, where each of the two legs is a quarter wave length long. The feed is at the centre, and the two legs are generally horizontal, and aligned away from the feed point 180 degrees apart. The dipole antenna exhibits gain perpendicular to the legs. The maximum gain is 1.64 times the isotropic antenna - a gain of approximately 2.15dBi. The gain off the ends of the dipole is much lower - the total power radiated by the antenna can not exceed the power being input, so if there is more radiation (gain) in one direction, there must be a corresponding reduction in a different direction. So: 2.15 dBi = 0 dBd 5.0 Effective Radiated Power - ERP and EIRP ERP and EIRP are both used to indicate the power achieved using an antenna.ERP compares the antenna performance with a dipole, and EIRP compares the performance with an isotropic antenna. So, the ERP is the power which would need to be fed into a dipole antenna, to get the same effect in the direction your antenna is pointing. EIRP is the power required for an isotropic antenna to gain equivalence. Practical example: My KX3 can transmit 15W. using the formula above, this is 11.77 dB. If I attach a Yagi-Uda antenna with a gain of 10dB, the ERP is 21.77 dB. Using the formula above, from this number you can calculate that this is the equivalent of 150.3142 Watts ERP. To understand the EIRP, we need to add 2.15 to the 21.77 dB value, giving 23.92 dB EIRP . Again, converting to actual power gives 246.515 Watts EIRP. If you are comparing antennas, make sure the same units are being used in all cases (either EIRP or ERP) - some sellers will use EIRP, because the values are higher! Check your licence conditions. Power output limits are often at the antenna, and don't include antenna gain. You can set your transmitter to output sufficient power to overcome any feed line losses, and present up to the power permitted to the antenna. A good antenna can then be used to get the transmitted power out and across the world. For feedline loses, the value is given in dB per 10 metres. For example, RG58 is 2dB / 10 metres (at 100MHz - choose the right feeder coax for your target frequency!). If you have 15 metres, then you will have 3 dB feeder loss, so half of your transmitter power will be lost in the feed line. If you know this and your transmitter can output more, then you can increase the transmitter power accordingly. So for 25W at the transmitter, with 3dB loss in the feeder, you can set the output to 50W. Some transmit power limits are set in ERP or EIRP, so you will need to calculate back from the antenna to see the maximum allowable transmitter power, to stay within the rules. 6.0 Combining values One result of the use of dB is that you can add the values together to understand the whole system gain. So, with our example above, if we have 11.77 dB of output power, then -1 dB insertion loss for a bandpass filter, -3 dB loss for the feeder, and 5dB gain on the antenna, the overall ERP is 12.77 dB. You can convert this back to Watts, to get 18.92W ERP. 7.0 Links Dipole information Yagi-Uda information Wikipedia information on Decibels Wikipedia information on ERP and EIRP Wikipedia information on Antenna Gain ERP & EIRP calculator from M0UKD Provide feedback on this episode .…

HPR4379: Mapping Municipalities' Digital Dependencies

לפני 6 ימים

—

This show has been flagged as Clean by the host. In this episode, I discuss my ongoing project aimed at mapping the dependencies municipalities have on major third-party digital services, particularly focusing on Microsoft and Google , given their dominance in the market. The aim of this research isn't about debating the quality of these products—it's assumed that with thousands of employees, these services meet most quality expectations. Instead, the focus is on the critical implications of widespread dependency and potential risks related to service interruptions or supply chain attacks. Why is this important? Supply Chain Attacks : High dependency means higher vulnerability to targeted disruptions. Business Continuity : Significant risks were illustrated by incidents such as the CrowdStrike outage in July 2024 , which forced Brussels Airport back to pencil-and-paper operations temporarily. My Research Approach: Primarily, I analyze the DNS MX records of municipalities: MX records typically reveal if mail services are hosted on Microsoft (Office 365/Exchange Online) or Google (Workspace). A high probability that using these providers for email also means municipalities likely depend on the respective cloud office suite (e.g., Word/Excel/SharePoint or Docs/Sheets/Drive). Preliminary Observations: Belgium, Finland, Netherlands : Over 70% of municipalities rely heavily on Microsoft mail services, a significant warning sign of dependency. Germany, Hungary : Fewer than 5% of municipalities use Microsoft or Google explicitly via MX records, though caution is necessary. Here’s why: Challenges Identified: Local MS Exchange Servers : Municipally hosted local installations aren't externally identifiable via MX records. Mail Proxies : Some municipalities use mail proxy services (spam/phishing filters) obscuring the actual mail service used behind proxy domains. Techniques Tested: SPF Records : Often reveal the underlying email service, though they may contain outdated information, lowering reliability. Telnet EHLO Commands : Municipalities commonly obscure their SMTP headers, limiting usefulness. Cloud Provider IP-Ranges : Investigating if mail servers run on Google, Amazon, or Azure infrastructure. Even if identified, this alone doesn't clarify if proprietary or replaceable services are used. TXT Records : Occasionally contain subscription keys or mail-related settings (e.g., MS subscriptions, Mailjet), but again, could be historical remnants. Unfortunately, none of these get to show me all of the third party services. Community Call: I'm reaching out to listeners and the broader community for ideas or techniques on reliably fingerprinting the actual digital service providers behind mail servers. Specifically: How to accurately determine if servers run Microsoft or Google services ? Any ideas to detect deployments of Nextcloud or similar open-source alternatives? Resources: Project Webpage : jurgen.gaeremyn.be/map.html Source Code : gitlab.com/jurgeng/mxcheck I'm looking forward to all your suggestions in the comments! Provide feedback on this episode .…

HPR4377: Password store and the pass command

לפני 8 ימים

—

This show has been flagged as Clean by the host. Standard UNIX password manager Password management is one of those computing problems you probably don't think about often, because modern computing usually has an obvious default solution built-in. A website prompts you for a password, and your browser auto-fills it in for you. Problem solved. However, not all browsers make it very easy to get to your passwords store, which makes it complex to migrate passwords to a new system without also migrating the rest of your user profile, or to share certain passwords between different users. There are several good open source options that offer alternatives to the obvious defaults, but as a user of Linux and UNIX, I love a minimal and stable solution when one is available. The pass command is a password manager that uses GPG encryption to keep your passwords safe, and it features several system integrations so you can use it seamlessly with your web browser of choice. Install pass The pass command is provided by the PasswordStore project. You can install it from your software repository or ports collection. For example, on Fedora: $ sudo dnf install pass On Debian and similar: $ sudo apt install pass Because the word pass is common, the name of the package may vary, depending on your distribution and operating system. For example, pass is available on Slackware and FreeBSD as password-store . The pass command is open source, so the source code is available at git.zx2c4.com/password-store . Create a GPG key First, you must have a GPG key to use for encryption. You can use a key you already have, or create a new one just for your password store. To create a GPG key, use the gpg command along with the --gen-key option (if you already have a key you want to use for your password store, you can skip this step): $ gpg --gen-key Answer the prompts to generate a key. When prompted to provide values for Real name , Email , and Comment , you must provide a response for each one, even though GPG allows you to leave them empty. In my experience, pass fails to initialize when one of those values is empty. For example, here are my responses for purposes of this article: Real name: Tux Emai l: tux@example. com Commen t: My first key This information is combined, in a different order, to create a unique GPG ID. You can see your GPG key ID at any time: $ gpg -- list -secret- keys | grep uid uid: Tux (My first key) tux@example. com Other than that, it's safe to accept the default and recommended options for each prompt. In the end, you have a GPG key to serve as the master key for your password store. You must keep this key safe. Back it up, keep a copy of your GPG keyring on a secure device. Should you lose this key, you lose access to your password store. Initialize a password store Next, you must initialize a password store on your system. When you do, you create a hidden directory where your passwords are stored, and you define which GPG key to use to encrypt passwords. To initialize a password store, use the pass init command along with your unique GPG key ID. Using my example key: $ pass init "Tux (My first key) " You can define more than one GPG key to use with your password store, should you intend to share passwords with another user or on another system using a different GPG key. Add and edit passwords To add a password to your password store, use the pass insert command followed by the URL (or any string) you want pass to keep. $ pass insert example .org Enter the password at the prompt, and then again to confirm. Most websites require more than just a password, and so pass can manage additional data, like username, email, and any other field. To add extra data to a password file, use pass edit followed by the URL or string you saved the password as: $ pass edit example .org The first line of a password file must be the password itself. After that first line, however, you can add any additional data you want, in the format of the field name followed by a colon and then the value. For example, to save tux as the value of the username field on a website: myFakePassword123 username: tux Some websites use an email address instead of a username: myFakePassword123 email : tux @ example . com A password file can contain any data you want, so you can also add important notes or one-time recovery codes, and anything else you might find useful: myFake;_;Password123 email: tux @example .com recovery email: tux @example .org recovery code: 03 a5 -1992 -ee12 -238 c note: This is your personal account, use company SSO at work List passwords To see all passwords in your password store: $ pass list Password Store ├── example .com ├── example .org You can also search your password store: $ pass find bandcamp Search Terms: bandcamp └── www .bandcamp .com Integrating your password store Your password store is perfectly usable from a terminal, but that's not the only way to use it. Using extensions, you can use pass as your web browser's password manager. There are several different applications that provide a bridge between pass and your browser. Most are listed in the CompatibleClients section of passwordstore.org . I use PassFF , which provides a Firefox extension . For browsers based on Chromium, you can use Browserpass with the Browserpass extension . In both cases, the browser extension requires a "host application", or a background bridge service to allow your browser to access the encrypted data in your password store. For PassFF, download the install script: $ wget https: // codeberg.org /PassFF/ passff-host /releases/ download /latest/i nstall_host_app.sh Review the script to confirm that it's just installing the host application, and then run it: $ bash ./install_host_app. sh firefox Python 3 executable located at /usr/bin/ python3 Pass executable located at /usr/bin/pass Installing Firefox host config Native messaging host for Firefox has been installed to /home/tux/.mozilla/native-messaging-hosts. Install the browser extension, and then restart your browser. When you navigate to a URL with an file in your password store, a pass icon appears in the relevant fields. Click the icon to complete the form. Alternately, a pass icon appears in your browser's extension tray, providing a menu for direct interaction with many pass functions (such as copying data directly to your system clipboard, or auto-filling only a specific field, and so on.) Password management like UNIX The pass command is extensible, and there are some great add-ons for it. Here are some of my favourites: pass-otp : Add one-time password (OTP) functionality. pass-update : Add an easy workflow for updating passwords that you frequently change. pass-import : Import passwords from chrome, 1password, bitwarden, apple-keychain, gnome-keyring, keepass, lastpass, and many more (including pass itself, in the event you want to migrate a password store). The pass command and the password store system is a comfortably UNIX-like password management solution. It stores your passwords as text files in a format that doesn't even require you to have pass installed for access. As long as you have your GPG key, you can access and use the data in your password store. You own your data not only in the sense that it's local, but you have ownership of how you interact with it. You can sync your password stores between different machines using rsync or syncthing, or even backup the store to cloud storage. It's encrypted, and only you have the key.

Use a central microphone for audience questions to avoid delays and maintain a smooth flow. Listen carefully to questions and rephrase them if necessary to ensure clarity for the panelists. Know when to politely wrap up discussions to keep the conversation moving.…
