Hurricane Helene: AAR Upstate SC pt2

After the storm, getting the generator going early and setting up the hand pump for the well made all the difference. A quick project with leftover well pump wire turned into a solid clothesline—an unexpected but handy addition that Carla LOVED. Through it all, AT&T held strong, and Starlink was exceptional. If you're interested, see below for a link featuring a free month for both you and me. It felt like living a real-life episode of "Prep Comms." The ZBM2 Industries antennas are outta sight—thanks, Deric! While the local 2m repeater was down, it didn’t hold us back; we had the gear ready, so radio wasn't top of my mind. That's one big lesson: when you’ve prepared well, the need for comms isn't a distraction, freeing you to focus on other tasks. The WLN KDC1 handheld radios continue to be incredibly reliable and cost-effective, with GMRS as our go-to system for family comms. It's a perfect service that doesn’t require any testing, making it ideal for family use. Though I used my ham radios sparingly, they came in handy for checking in on 40m HF (JS8Call) and daily Winlink check-ins over VHF Packet. Just North of us the Mt. Mitchell Ham Repeater was a true lifeline, saving lives daily. Be sure to watch KM4ACK Jason’s video, linked below, about the welfare nets on this repeater. Locally, our phones worked well, so ham radio took a backseat for us, though just 45 minutes away, it was a crucial lifesaver. Brother-to-brother comms on CB were also reliable, showing that there’s a role for every communication method. And while I stayed busy with work, the family stepped up; we learned countless lessons that we’ll carry forward. Although some coax-internet is still down, Verizon failed most while ham radio absolutely shined across North Carolina. The BTech 6x2Pro proved essential for both farm and fire department communications. This experience underscored the value of preparedness and inspired us to add an ECOFLOW 2700W solar generator to back up our primary generator. No matter where you’re starting from, take that first step toward readiness. Don’t be discouraged—I’m here to help! That Simple Pump from Scott Hunt (Practical Preppers) was a true lifesaver, keeping water flowing through it all. Men, husbands, dads—let’s get you started! Plan C Solutions and The Family Radio Guy are coming soon to help you and your family prepare for the upcoming unknown.

Hurricane Helene: AAR Upstate SC pt1

Here's a timeline rundown from our Helene Prepping and Recovery After preparing gas and propane midweek, we ensured all equipment was charged and ready. At 0400 on the 27th, my mini comm hub was active. By 0630, local repeaters went offline, and at 0730, we lost power. With severe winds raging, we canceled work, activated our generator at 0800, and monitored fire and ham bands on the BTech 6X2Pro. Once the rain subsided, we utilized the Simple Pump, though filling the tub beforehand had slipped my mind. We assessed farm damage, surveyed nearby areas, then focused on family, using GMRS almost exclusively. Around day 2, the local club activated the backup 2m repeater. We quickly learned the importance of organizing supplies, checking on neighbors, and securing water for extended family. Thankfully, AT&T held steady, and Starlink was invaluable. Our generator was essential, though a wiring fix was needed post-storm. By Sunday, life resumed as near-normal, with only brief setbacks. Reports of coax internet still remain down. Fiber proved resilient yet delicate, and Verizon was unreliable. Ultimately, radio communication, though modest in our setup, was a lifeline for many in WNC, showcasing its critical role during a crisis. KM4ACK Helene Net Video! (Must Watch!)

CB Radios for Preppers: pt 3

Continuing the CB Radio for Preppers and Caleb looks back to his teens and how CB Radio was what lead him to Radio Shack, FM Radio and Ham Radio and eventually Podcasting. CB isn't what it was, but it's a Very Practical Comms Tool you should consider for your preps! Hub City Mercantile is the Offical Show Sponsor of the Prep Comms Podcast! Radiodity Micro CB Radio Antennas and Cables The 11-meter band sits within the **high-frequency (HF)** spectrum, and its properties significantly affect the performance of CB radios. Frequencies within this range can travel through the ionosphere, especially during favorable atmospheric conditions, making **skip propagation** possible. Skip propagation allows signals to bounce off the ionosphere, potentially reaching hundreds of miles beyond their typical range. However, not all conditions favor such long-distance communication. Atmospheric disturbances, solar cycles, and interference from other devices can limit the effective range of CB radios operating in the 11-meter band. For most users, this range averages between **1 to 15 miles**, depending on the terrain and other factors. AM vs. SSB Modes: Performance and Usage CB radios typically operate using one of two communication modes: **Amplitude Modulation (AM)** and **Single Sideband (SSB)**. Both have their advantages and trade-offs, impacting how CB users experience clarity, range, and performance. AM (Amplitude Modulation) The AM mode is the default communication method for most CB radios. It works by modulating the amplitude of the radio wave to carry the audio signal. AM is relatively simple in terms of technology and is favored by truckers and casual users for local communication. However, it has limitations, particularly in clarity and range. AM transmissions are more susceptible to **noise interference** from electrical devices, power lines, and atmospheric conditions. The sound quality tends to degrade over longer distances, and the range can be limited, typically extending no further than **5 to 10 miles** in most conditions. While convenient for general communication, AM may not offer the performance needed for long-distance or emergency communication. SSB (Single Sideband) SSB mode offers a significant upgrade in performance, allowing CB users to achieve greater range and clarity. Unlike AM, which transmits a full signal that includes a carrier and both upper and lower sidebands, SSB transmits only one sideband (upper or lower), removing the carrier. This makes SSB more **efficient** in terms of power and bandwidth usage. In practical terms, SSB can extend communication range by **50 to 100%** compared to AM, making it ideal for those who need to cover larger areas. It also provides clearer audio, especially in noisy or interference-prone environments. The trade-off, however, is that not all CB radios support SSB, and it requires more precise tuning for optimal performance.

Scanners for Aviation Listening

Editors Note: Attention. This program was recorded less than 24 hours before President Joe Biden announced he was giving up his re-election bid. This significant development suggests further changes are on the horizon. You are encouraged to Prepare your communications accordingly. The past ten days have been nothing short of tumultuous. Honestly, I foresee even more chaos before we see any real calm. With that said, thank you for tuning in to this episode. Today, I jump into current events (against my wishes), including the Trump Rally Shooting and the CrowdStrike outage. Then we also explore the use of aviation scanners and a faithful listener (Craig) reminded me of that end of the spectrum ('scuse the pun). Additionally, I discuss how your $20 walkie-talkie isn't truly a scanner but might suffice in a pinch. The $35 pawn shop scanner is still a better choice!
