I finally succeeded in making contacts using PSK-31.
My location is on the third floor. The antenna is a 28-gage random wire just outside my window in the "Stealth mode." I'd like to use an inside antenna but the cement / rebar construction of my walls prevents any signal to escape my apartment. PSK-31. The software I use is Digipan. The rig is my faithful Yeasu FT-817 running 5 watts into Raskal GLK built from a kit. The computer is a laptop by Dell.
I use Multi-PSK software the most primarily for AMTOR FEC on Navy MARS.
