Repeaters / Linked Systems I Frequent

HF Radio

In October, 2021, I bought my first HF radio, a Yaesu FT-891, an LDG Z-11 Pro II tuner and a Chameleon EMCOMM II antenna.  Since that time, I’ve acquired and built several more antennas and one more HF Radio, the Yaesu FT-100D.  My favorite antennas are the Chameleon MPAS Lite and the Chameleon Tactical Delta Loop both of which are outstanding for portable use.  I’ve used HF in the car, in parks, on summits and even while traveling across the United States!  On the digital side of things, I’ve figured out how to use Winlink over VARA HF.  Something I would like to do in HF eventually is digital voice over HF.
