This week, we're looking at some interesting developments in the LoRa space, particularly how it's being leveraged for amateur radio applications. We've got a few resources that touch on mesh networking, off-grid text messaging, and the integration of LoRa with APRS. For those experimenting with portable setups or considering resilient communication methods beyond traditional HF, these items offer practical insights. There's also a utility for managing virtual serial ports, something that comes up often when interfacing modern transceivers or microcontrollers with logging software or control applications. It’s a mix of hardware-adjacent firmware projects and mapping tools, all relevant for operators keen on digital modes and self-contained systems.

This week, we’re looking at some practical antenna builds and a handy reference for precise timing. For those operating on 70cm, there are a couple of interesting options: a UHF Double Bazooka Antenna Construction guide details building with RG213, something worth considering for fixed stations needing a clean pattern. Then, for the mobile crowd, especially those on two wheels, a Vertical J-Pole for motorcycle use offers a compact solution for 430-450 MHz. It’s a robust design, which is key when you’re out on the road. Finally, for anyone needing to calibrate their rigs or just curious about propagation, the HF Time Broadcasts and Time Signal Stations List is a solid resource. It’s always good to have those frequencies handy, whether for a quick check or more serious experimentation.

This week, we're looking at a few interesting builds, from compact multiband solutions to specific band optimizations. There's a solid 50-watt amplifier project for the HF bands, something that comes up often for those needing a bit more punch without breaking the bank. We also have a couple of vertical antenna designs, one covering multiple bands and another specifically for 20 meters, which is always a popular choice for portable work. For those running an Icom IC-705, there are some practical insights into maximizing its potential in the field. And for stealth operations, a window loop antenna for 20 meters offers a clever approach. These selections should provide some good food for thought for anyone considering their next antenna project or looking to refine their portable setup.
