| Tuning: | Three ganged capacitors in RF circuits, three ganged capacitors in 1st variable IF-circuits. Continuos tuning by a knob (transmission 10:1 pushed and 160:1 pulled) via 1st oscillator. Alternatively above 1.5 MHz exact setting of 1st oscillator in steps of 100 kHz with calibrator for RF conversion to variable 1st IF (1180 to 1080 kHz), fine tuning via 2nd oscillator (1280 to 1180 kHz) for further conversion to 2nd IF (100 kHz). |
| Crystal: | 1x 100 kHz for calibration. |
| Dials: | Very big colorful coarse dial, first segment is fine tuning dial 100 kHz. |
| Comments |
| This model was designed for the marine market replacing the E 61, E 66a (LF, HF, 1948), E 303, E 305 and E 306 (all HF, 1952 - 1954) receivers. The E 566 was licensed as a class one receiver by the "Deutsche Bundespost". A standard receiver like competitor Hagenuk UE 12 on German ships. The twelve bands are selected by push-buttons on the left. Called "parrot cage" by the operators, referring to its colorful dial. Quite suitable for SSB reception using the product detector at 1.8 kHz bandwidth in CW mode. |
| Variants |
| The Debeg E 566 has been produced by Siemens. It is very similar to the Siemens E 310. The E 566 first had a dark green cabinet and front panel, later it often was light gray. The headphone jack can be positioned underneath the main tuning knob or on the far left. |
