Portable Field Radio, Portable Antenna, Interface, Software & More

摘要

This month we take a look at two items for portable operations-a three-band portable field radio and a very portable vertical antenna. We also cover a new online ham radio "second-hand shop" and a USB CW and PTT keyer. Next up is a Linux logging software program with a twist. Finally, we visit the Amateur Radio Website of the Month. Hendricks QRP Kits recently introduced a three-band portable field radio, the PFR3 XCVR (photos A, B, and C), designed by Steve Weber, KD1JV. This CW-only transceiver provides full band coverage on 40, 30, and 20 meters. Receiver specifications include an MDS (minimum discernible signal) of 0.2 μV and a selectivity of 300 Hz. Receive current required on receive is only 47 ma and drops to 34 ma when idle.
