The Swiss Air Force did buy four French double-seater jets Dassault Mirage III to be
used aus trainer aircraft in 1964, 18 more Mirage IIIRs reconnaissance jets
and 37 Mirage IIIS interceptors have been built by Federal Aircraft Works F+W Emmen
under French licence in 1965/1966.
The "Mirage III" came already with the French VHF aircraft radio Omera TR-AP 28,
after the shift of military aircraft communications in the UHF frequency band
from 225 - 400 MHz (with 25 kHz channel spacing), the UHF aircraft radio
Omera TR-AP 22 / SE-051 was used.
220 - 400 MHz, xx channels
telephony, pout ca. 5 W
Control unit for channel selection, rotary transformer power supply
powered from aircraft power system 28V DC.
When Switzerland acquired the Dassault Mirage IIIRS reconnaissance jet and the Mirage IIIS
interceptors, the French made Omera VHF aircraft radios became part of the Swiss
Air Force technical equipment.
The Omera TR-AP 22, Swiss designation SE-051, is a UHF air band radio covering
the 220 - 400 MHz range, the output power is around five Watts.
||The operation frequencies are stored in the frequency memory "Tambour"
by ground personnnel, the "Tambour" is inserted in the front panel of the
control unit after the frequencies have been stored.|
The control unit is very simple to operate, it comes only with the channel
selector, an operation and a volume knob (and even a tiny pushbutton for emergency
morse code transmissions).
I would be very thankful for further information and images.
Information from the Swiss Air Force Museum Dubendorf, where the equipment is displayed.
