The ST-G7, a black quartz synthesizer digital FM/AM tuner, was the last great tuner made by Technics. (The silver version in our photo, taken from k-nisi's website, was sold only in Japan.) It has the electronic equivalent of 5 gangs and 4 ceramic filters. Most prominent on the front panel are a nice yellow-on-blue LCD display, AM and FM band selection buttons and 8 buttons for 16 preset stations. Behind a fold-down glass door are some useful features, including pushbuttons for Normal or Super Narrow IF bandwidth, signal strength readout in dB, and a recording calibration tone, plus the typical muting, stereo/mono, scan level, tuning up/down, etc. The tuner's computer automatically selects the optimal reception mode, including the proper bandwidth setting and whether the station is strong enough to be in stereo, but these choices can be manually overridden. On the back panel are the usual antenna jacks (both screw terminal and loop antenna jack for AM), a jack for a wired remote control, and a jack labeled "Computer I/O Terminal." We haven't tested this feature, but the following text appears in the lower middle of the front panel: "Computer System - This equipment includes the I/O terminals on the rear panel to connect with a computer system."
With a Terk "AM Advantage" antenna connected to its loop antenna jack, the ST-G7 showed off a sensitive and terrific-sounding AM section. Our sample was an international model with a Euro power plug. If you hold down the FM or AM bandwidth selection button, the tuning increments change from .2 to .05 MHz for FM and from 10 kHz to the European 9 kHz spacing for AM, but hold the buttons again and the tuning changes back. The .05 MHz tuning increments might be useful in off-tuning away from a strong local station in order to hear a weaker adjacent. The ST-G7 got a rave review from Don Scott in Stereophile, primarily for its excellent stock selectivity on FM, and it might be excellent with a couple of narrower filters.
