ICF - PRO70 Scanner Receiver
überarbeitet am 30.10.2010
In the same shaped cabinet as the Air band receiver AIR-7, Sony presented another scanner receiver in the year 1987: the ICF-PRO70 was sold in Germany in a version compatible with the regulations / frequency band restrictions of the German Post, the very similar set with a plug in VHF converter never got admitted to be sold in Germany by the FTZ. There have been the possibilities to order such sets in Switzerland or Holland (for export only) or to bring one back from a trip to the far east.
ICF-PRO70 Type 1: 150 kHz - 108 MHz
ICF-PRO70 Type 2: 150 kHz - 29995 kHz as well as 87,6 - 108 MHz
ICF-PRO70 Typ 3: 150 kHz - 26100 kHz as well as 87,6 - 108 MHz (for Germany)
ICF-PRO80 : 150 kHz - 108 MHz as well as 115,15 - 223 MHz with the attached frequency converter.
The Sony ICF-PRO70 is a handheld scanner receiver with a walkie talkie design similar to that found with the AIR-7; it has been sold in different versions with frequency restrictions te get approval by the post in Germany and Italy.
The receiver has a similar shape as a walkie talkie, it has the same dimensions as the AIR-7 with 9 x 18 x 5 cm and has a weight of 650 g. Instead of the flexible rubber covered antenna, it comes with a much longer telescopic antenna, the base element of which is covered with yellow plastic. The antenna is plugged into a BNC antenna socket at the top face of the radio.
At the radio's top face, You find the green coloured pushbutton acting as main switch in the left corner, next to it the volume and squelch control. When the volume control is depressed, it acts as tone limiter, the squelch is in automatic mode, when the squelch button is depressed. With the outside ring of the rotary control at the right, You can selecrt one of the four memory pages with 10 memories each, the inner part acts as fine tuning for the AM andspecially CW / SSB modes. In a back row, You find the antenna BNC connector and the jacks for earphones and tape recorder.
In the upper part of the front panel, You find the liquid crystal display for the frequency display, mode / scanning display and management of the memory channels, in the lower left corner a small red tuning LED.
Use the FUNCTION key followed by a corresponding numbered key 4, 5, 7, 8 , 9 to select the reception mode: the receiver has two AM bandwidths and FM-wide (FM broadcast stations) and FM-narrow (utility communications), but only the variant 3 of the ICF-PRO70 is equipped with the NBFM mode. When in SSB/CW mode, the FINE control can be used to adjust the CW beat note or to fine tune the SSB signal for optimal readibility. In the modes AM-W and AM-N, these fine tuning option has to be activated by pressing FUNCTION + 6. In the mediumwave range, the channel selector in the battery compartment should be in the correct position 9 / 10 kHz, 9 kHz is used for the European channel grid and 10 kHz in the Americas.
The little speaker is located at the bottom section of the frontpanel, there is a writing HI SCAN, so You can make the difference to a AIR-7 in an online auction even from a poor image.
The Sony PRO-70 is a scanning receiver capable of shortwave reception, but I think, it won't have been sold too often with the frequency restrictions for Germany. A small travel radio as the ICF-7600D will do the job as well, as long as not all scanning options are needed.
