• HPR4527: Overly Complicated Media Ripping setup

  This show has been flagged as Clean by the host. Hello, this is your host Archer72 for Hacker Public Radio. In this episode, I share my overly complicated media ripping setup, and hope it helps someone. First of all, I have revised my media ripping setup since HPR3294 - Update to MakeMKV to back up media I’ve changed my mind about only using a terminal for ripping media, and it was time to make a change. Now, I start both MakeMKV and Handbrake from a remote GUI, either on my laptop or phone.

• HPR4526: Baofeng and SDR++

  This show has been flagged as Clean by the host. Goal: send a voice signal on VHF or UHF, receive and record with SDR via RTL dongle Core Problem and Resolution An issue may have been a hardware I/Q Imbalance in the RTL-SDR, which suppressed the desired signal, resulting in very low output volume that required excessive manual amplification. Initial Problem: Very quiet, barely audible recorded audio, initially on UHF 433 MHz Key Discovery: An I/Q imbalance caused a repeating signal "image" in the spectrum, Frequency Change: Switched to the VHF 145.500 Mhz band, Gain Override: To overcome the defect and the failing AGC, gain stages were manually adjusted: Squelch: Squelch (SQL) was set to OFF (0) to prevent the software from muting the quiet, legitimate signal. Adjusted the final Sound Output/Recording Gain on the host OS to match the maximized digital output, achieving audible voice. Summary of Key Radio and Software Settings Transmitting Radio (Baofeng UV-5R): Operation: Simplex (direct radio-to-SDR). Mode: Narrowband FM (NFM). Receiving Software (SDR++): AGC: Disabled (Crucial override). RF/Tuner Gain: Adjust (Inject best signal power). AF Gain: Adjust (Produce loudest digital audio). Squelch (SQL): OFF (0) (Prevent muting of quiet signal). Filter Bandwidth: 12.5 kHz(Correct setting for NFM). The ultimate resolution was forcing input and output gain in SDR++ and volume adjustment in Audacity Provide feedback on this episode.

• HPR4525: Using mail merge in thunderbird

  This show has been flagged as Clean by the host. As the new year show is upon us, Ken needs a way to send out some mail messages to fellow Free Culture Podcasters . Rather than just putting every one on the bcc, a more personal mail list can be done using the Thunderbird Mail Merge add on. Install Download it, and then open Thunderbird, select "Tools", "Add-ons and Themes". Then press the Cog icon ⚙, and select "Install Add-on From File...", Finally select the downloaded file and confirm. Creating the CSV To use it create a list of emails with a heading, "PrimaryEmail" in our example. $ cat maillist2025.csv PrimaryEmail [email protected] [email protected] [email protected] Using Mail Merge Just add each column field to the address boxes, or the body of your message, surrounded by double curly brackets . In our case we add "{{PrimaryEmail}}", in the to field. Then press the new "Mail Merge" button in the top right. Select "CSV" and select the file you prepared before. If you are sending now, then you can put in a random delay, so that when you press send there will be a delay between each of the mails been sent. If you select the default send later, then after pressing send the mails will be placed in the outbox so you can send them later.
