Zenith B&W with digital tuner

[wa2ise]

It defaults to channel 2 when power is turned off...you have to tune it every time the power is turned on

It seems like RCA has a memory retention circuit as the 1970's/early 80's RCA's with the manual power switch and the keypad do remember the last channel tuned, as long as the set is plugged in.

Some RCAs from the late 70's and early 80's use a diode matrix to "program" the default channel. So one should be able to reconfigure the diodes to make the set come up on say channel 3. Thus someone could slave the set to a remove controlled cable box, and have the set's power cord plugged into a controlled outlet in the back of the cable box. Hit the remote, and have the set not come up on channel 2, but 3. Most cable boxes could output channels 3 or 4 but I've never seen one output to channel 2.
