SCA.9
With the R71A in the FM mode, tuned to 67 kHz, I con-
nected the ICOM's vlf antenna input through a 0.1 ufd
capacitor2 to the earphone jack of a $16 General Elec-
tric AM/FM portable radio, and can now listen in on the
world of SCA!
In the first few minutes of tuning around, I've heard
the Physicians' Network, Muzak, commodity reports, and
several data transmissions.
I built a simple SCA interface, consisting of a capaci-
tor and resistor, into a plastic film canister.
