- 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.
