RCA OFFERS YOU A COMPLETE LINE OF AVIATION RADIO EQUIPMENT
QUALITY RUGGEDNESS SIMPLICITY
LOW INITIAL COST
LOW OPERATING COST
WHATEVER your aviation radio requirements, RCA can meet them-with standard equipment backed by years of experience in every radio communications field. Several new pieces of equipment, conforming to RCA’s high standard of quality, make the line complete. This is the type of equipment you want, because it is based on recommendations from you or others whose requirements are similar to yours.
Typical of RCA aircraft equipment are the two new light-weight receivers, AVR-7 and AVR-7 A. Unquestionably the smallest, lightest, least expensive aircraft receivers of proven merit, the AVR-7 and AVR-7A are nevertheless little giants for performance. They’ll give you a thrill. The new RCA Aircraft Transmitter, weighing only 38 pounds, the AVR-2 Radiobeacon Receiver and the AVR-3 Communication Receiver offer similar advantages.
You can’t go wrong when you buy an RCA.
Two New Light-Weight, Low-Cost Aircraft Receivers -A New Transmitter Weighing Only 38 Pounds!
Aircraft Beacon-Entertainment Receiver. A 4-tube superheterodyne receiver with remote control requiring no other source of power than your aircraft battery (6 or 12 volts). Brand new, low in cost, giving exceptional service on both beacon and entertainment bands.
MODEL AVR7 A
Aircraft Beacon – Communication Receiver. The same as AVR-7 except that the communication band is substituted for the entertainment band. As with the AVR-7, band changing is simply and quickly accomplished by means of a push-pull knob. Ideal for standard or auxiliary service.
Aircraft Transmitter. CW and MCW telegraph, 100% modulated telephony. 20 watts output. Operates on any three pre-specified frequencies (selective in flight) between 2,000 and 6,500 K.C. Entire equipment, including dynamotor power supply. contained in a single package. Low cost.
AVR-2 AND AVR-3 STANDARD AIRCRAFT RECEIVERS
Aircraft Radiobeacon Receiver. A 6-tube superheterodyne, dynamotor-operated receiver with local or remote control. Requires no other power supply than your aircraft battery (6 or 12 volts). The AVR-2 Radiobeacon Receiver is satisfactorily serving over 200 users today!
Aircraft Communication Receiver. Companion to, and including the same outstanding features as, the AVR-2. Six-tube super-heterodyne, dynamotor-operated, with local or remote control. Requires no other power supply than your aircraft battery (6 or 12 volts).
RCA AIRPORT EQUIPMENT UNEXCELLED FOR VALUE
JUST as RCA aircraft equipment is built to please the pilot, so is the RCA ground station equipment built to please the airline or airport management. Combining technical excellence with smart appearance, ruggedness, operating simplicity and low cost, the RCA ground transmitters and receivers are all that the up-to-date airport or airline office could wish. The non-obsolescence feature of the transmitters, whereby they may be adapted to speech amplification systems and radiobeacon service, or their power increased to any allowable limits-all at low cost is an advantage the importance of which will be universally recognized. All RCA airport equipment is housed in handsome matching 2-tone gray cabinets.
