Notes

Final and last Trans-Oceanic model, not to be confused with the Royal 7000, which is completely different!

Built-in BFO for SSB reception, squelch for PSB and AIR bands, variable RF gain.

Frequency Coverage:

LW: 170 – 450 KHz, MW: 540 – 1610 KHz, SW 1: 1.8 – 4 MHz, SW 2: 4.0 – 7.5 MHz, SW 3: 7.5 – 10.0 MHz, SW 4: 11.0 – 15.5 MHz, SW 5: 15.5 – 22 MHz, SW 6: 22 – 30 MHz, SW 7: 26.9 – 27.5 MHz ( CB ! ), FM: 88 – 108 MHz, VHF AIR: 107.8 – 136.5 MHz, VHF HI (PSB) 143.5 – 174.5 MHz

The R-7000 employed an innovative approach using the FM’s 10.7 MHz IF for all bands, effectively eliminating the problem of “images” in SW reception ( which fall at multiples of the IF frequency ) without the added complexity of going to a dual conversion design.

Only one IF string was needed rather than two.

Made in Taiwan by Zenith Taiwan Corp., a subsidiary of Zenith Radio Corp. Chicago, IL

Hi all....The on/off switch shuts down dial lights, but not the radio. Anyone have any repair ideas? Also I am in need of dial lamps, the bulbs read GE18.Anyone know of source to get them?  Thanks  AL

I repaired radio by removing chassis, and cleaning the switch, and all contacts using 'Gold' spray cleaner. I used Sylvania #74 bulbs for dial lights ( 14 volt...perfect match)   Thanks   AL

 I buy my dial lamps at antique electronic supply.  Use contact cleaner on switch and check circuit with a schematic for circuit modification.
