"only two still exist" of the manufacturers? Not so. If you're going on "still exist, in the exact same form, making radios", the only brand around is Roberts. If you go for "still exist, at all", Bush is there - it went bankrupt in the 80s and is now an imprint of Alba. However, Cossor is owned by Raytheon, General Electric and Ferranti by Ericsson, Decca Records still operate, owned by Universal, and so on. --85.134.141.187 16:48, 21 April 2007 (UTC)[reply]

Technical aspects

The people of the receiver model VE301W was equipped with three tubes: triode audion as REN904 with feedback , output tube RES164 and the mains rectifier RGN354 . By the feedback in the stage Audion the necessary sensitivity was achieved. The speaker was a highly resistive cantilever with high efficiency , but excessive sound. The People receiver are considered typical representatives of Einkreisempfänger of the family of straight receiver .

The VE 301 Dyn already contained, besides a more sensitive RF tube also an electrodynamic loudspeaker . A little earlier - namely 1937 - the original model ( VE301 ) was slightly revised and then under the name VE301 Wn ( Wn for " new AC " ) offered . In contrast to the original model of this device had no cage coil , but a fully adjustable tuning . In addition, better audio stage was ( with the pentode AF7 ) , which improved the sensitivity installed. Externally, the unit did not change . Only the antenna connections (3 x Antenna, 1 x earth ) were now no longer side of the case , but on the rear panel.

The people broke the receiver still very widespread simple crystal receiver from the individual headphone channels. It was not until some years after the Second World War, the most popular receivers were replaced first by the powerful superheterodyne receiver and the emerging interference poorer FM radio and later by new transistor devices . More Products / Manufacturers Labor Front receiver DAF1011

Later on other devices

the German small receivers DKE38, and in 1938 an updated version of the actual people came to the family of the recipient nation receiver - the VE 301 Dyn added . Whether you wear the device , except for the SU 301, to the right people Recipient name is disputed ; fellowship recipient is likely to be the correct name .

The Labor Front receiver and two Olympic DAF1011 case ( DOK36 and DOK37 ) are also so-called People's Receiver . These devices have been designed as a straight receiver , but technically more complex than so-called multi-loop receiver . For the recipient , there were people as accessories various traps and other devices and antenna matching selectors. In general, just a long wire as so-called long wire antenna or T antennas were used for the people's receiver .

With a splitter , as the DWt 52 and the switch DDa 38, 301 G , it was also possible with the People's receivers, such as VE to receive the radio wire.

Lack of longwave

The Utility Set had limited reception on medium wave and lacked a longwave band to frustrate attempts at receiving foreign broadcasts The crude tuning scale listed only BBC stations.

The lack of LW was to reduce component count (the whole point of the design being to economise on scarce materials) The necessary coils for LW would have required many turns of (scarce) copper wire. LW domestic broadcasting had been suspended during WW2 in UK and most enemy propaganda was on MW and/or SW anyway.

In complete contrast to the situation in Nazi Germany and occupied Europe Listening to foreign propaganda broadcasts (while officially discouraged) was not actually illegal in wartime Britain. Nor was there any attempt to jam such broadcasts (an exception being the "Aspidistra" transmissions intended to intrude on domestic German stations late in the war).

Its hardly surprising that tuning dials only listing BBC stations but the set designers while not actively setting out to prevent listening to other broadcasters were hardly going to facilitate it. 176.24.162.131 (talk) 22:28, 25 December 2014 (UTC)[reply]
