AX1 by Elecraft is an ultra-portable two-band antenna system for 20 and 17 meters.

This week, we've pulled together a few items that touch on practical station enhancements and field operations. There's a good look at setting up a HamClock using a Raspberry Pi, which is always useful for keeping track of propagation and time zones, something that comes up often whether you're chasing DX or just monitoring local nets. For those inclined towards building, we have details on a QRP digital transceiver project, an interesting take on low-power digital modes. Antenna builders will appreciate the discussion around practical wire Yagi designs, particularly for portable or temporary setups where mechanical simplicity is key. We also found a resource on a 144-28 MHz transverter for SDRs, which could open up some interesting VHF/UHF experimentation. Finally, a guide for a DIY USB Keyer for PowerSDR rounds out the selection, a handy addition for CW enthusiasts looking to integrate their keyer more tightly with their software-defined radio.
