 Next to the antenna connectors, some fuses and a socket for crystal controlled fixed frequency operation, is a round signal stregth meter switchable to display the plate / B+ voltage. A round knob allows to dim the dial lights. Next to the antenna connectors, some fuses and a socket for crystal controlled fixed frequency operation, is a round signal stregth meter switchable to display the plate / B+ voltage.

-Below You find the dial of the turret tuning assembly. Due to the construction of the set, the analog dial is not linear, so on higher frequencies,​ the 100 kHz lines are much nearer then in the low band segments - thus dial accuracy is better low frequencies. Dial calibration has been made at the manunfacturer:​ using a crystal controlled calibrator providing a spectrum of known frequencies,​ the frequency marks have been engraved individually on each set's dial.+Below you find the dial of the turret tuning assembly.

 The big rotary control at the left acts as bandswitch and operates the turret tuner, the right knob is the main tuning control, that can be locked mechanically on a tuned frequency. The shortwave band segments are 1,5-2,5 MHz, 2,5-4,1 MHz, 4,1-7 MHz, 7-11,5 MHz, 11,5-19,2 MHz and 19,2-32 MHz. The big rotary control at the left acts as bandswitch and operates the turret tuner, the right knob is the main tuning control, that can be locked mechanically on a tuned frequency.

 The military sets have been equipped with a seven day movement Revue mechanical station clock. Quite often, only three little holes below the speaker grille witness that the clock has found a new owner. Caution: the clock fingers are painted with Radium containing flourescent colour, this can cause trouble when a set is sent abroad and the clock indicates radiation on a Geiger counter. The military sets have been equipped with a seven day movement Revue mechanical station clock.

-I love the performance of my E-627 on shortwaves: the 14 valve single conversion set offers above average reception on shortwaves. Tuning on the high frequency bands is difficult, on the lower bands with the original dials ok, an external frequency counter can give You relief from guessing the reception frequency, there are some counters that can be set to automatically subtract the receivers IF of 455 kHz.+I love the performance of my E-627 on shortwaves: the 14 valve single conversion set offers above average reception on shortwaves.

 This fifty year old set from the internationally not very well known manufacturer [[Autophon]] offers very pleasent shortwave reception - and usually this sets work very reliably, what You would expect from "Swiss Made" quality. Not to mention that Swiss Army gear is usually heavy, rock-solid and is designed and built to last centuries... This fifty year old set from the internationally not very well known manufacturer [[Autophon]] offers very pleasent shortwave reception - and usually this sets work very reliably, what You would expect from "Swiss Made" quality.
