(AM-6675/URT ONLY) See Note 1 below
4.4 KVA at rated full power output (AM-6675/URT only)
3400 Watts at rated full power output
100 milliwatts nominal
1 kilowatt PEP for USB, LSB, ISB and compatible AM (350 watts of carrier) Emissions: 1 kilowatt of average power for CW, FSK and FAX emissions
Front panel control allows power reduction to l00W PEP
2.0 to 30.0 MHz in 19 bands
-40 dB nominal
10 seconds
0 to 50 degrees C
Five input lines carrying coded signals
+28 volt input from external source places RF amplifier in standby condition
+20 volt input from external source places RF amplifier in operate condition
Grounded input places RF amplifier in keyed condition
Grounded input alters APC and PPC for compatibility with CW/FSK mode of operation
Grounded input provides key interrupt when antenna or multicoupler not in operating or tune status
Grounded input causes reduced power to antenna coupler during couplers tune cycle
140 cubic feet per minute CFM
14.7 PSI maximum at 140 CFM

Note 1:
The AM-6675/URT(SA) requires a external PP-3916/UR Power Supply, and appears almost identical to the U.S. Military model AM-3924B(P)/URT RF Amplifier found in the AN/URT-23B(V) Radio Transmitting Set.
The main difference is in the color of the exterior which is a very light green instead of the usual light gray.
The AM-6675/URT(SA) was made for Saudi Arabia as part of an air defense system supplied by Litton in the late 1980's. Our units came from Litton when their contract was completed and are unused.
