überarbeitet am 27.9.2010
A receiver with a "completely different" design is the Sony AIR-7, a compact receiver covering the air band, it comes in the "look" of a walkie talkie.
AIR-7: AM 150 - 2194 kHz, VHF FM 76-108 MHz, AIR Band 108 - 136 MHz AM, VHF 144 - 174 MHz FM
AIR-8: AM 150 - 2194 kHz, VHF FM 76-108 MHz, AIR Band 108 - 137 MHz AM, VHF 144 - 174 MHz FM
The Sony portable Air Band receiver AIR-7 appeared in 1985, it covers not only the VHF Air band for ground - air / air - air communication but also the FM broadcast band, long- and mediumwaves and a small part of the shortwave spectrum up to 2194 kHz.
The shape of the receiver is similar gto the one of a walkie talkie, the dimensions of the AIR-7 / AIR-8 are 9 x 18 x 5 cm and the weight 500 g. A rubber coated flexible antenna is connected to the BNC antenna jack at the top face of the receiver.
On the upper face of the AIR-7, You find a green pushbutton, it's the main power switch of the receiver. The small volume and squelch control next to it can be depressed. With the modes switch, the modes AM (LW-SW), FM (VHF broadcast band), AIR (for the AM Air band) and PSB (for the VHF band, covering the 2 m amateur radio band).
On the upper part of the frontpanel, You find the LCD panel for the frequency display and the memory channel information and in the left lower corner a tiny red tuning LED.
The tiny speaker is located at the bottom of the front, it carries the designation AIR BAND, so an AIR-7 receiver can be recognized from poor resolution online auction imaged from the similar shaped but technically completely different PRO-70 / 80 receivers.
The Sony AIR-7 is a special receiver for Air Band coverage and will be of interest to those who like to monitor the air traffic of the nearby airport or need the airport weather informations. Because of the frequency coverage - in Germany it has been illegal even to have a radio in Your possession that offered some frequency coverage other then the standard broadcast bands - the numbers of sets sold in Germany probably has been very small, so the radio is not easy to find in Western Europe.
