E35
This item is also replaceable by the SG -1170. Issue SG-1144 until stock is
exhausted. No additional procurements for SG -1144's are anticipated.
E36
Replaced by SG -1144 (or SG -1170, see E54) when used in all
applications other than FM radio repair. When used to repair FM radios,
the AN/GRM-114A can replace this item at bench positions designated for
the AN/GRM-114A.
The AN/GRM -50 series has an output of +22.5 dBm (3 volts) into 50 ohms.
E82
The SG-1144 and the SG -1170 both have output voltages of +13 dBm
(1 volt) into 50 ohms; the AN/GRM -114A, 0 dBm (0.1 volts) into 50 ohms.
Where the AN/GRM-50 series is used to support AM radios with high
output power that require 3 volts RMS stimulus to drive audio circuitry
(such as the AN/GRC -106), units will retain the AN/GRM-50's. Units that
do not require output voltages above +13 dBm for testing end systems
such as the AN/VRC -12 and AN/PRC-77 radios should purge the
AN/GRM -50's with the SG-1144 or SG-1170 or AN/ GRM -114A (also see
E36, E37, and E54.)
Item does not have LIN, however, item is capable of being replaced by
P2
TEMOD item and will eventually be removed from the field by attrition. Unit
should take action to update authorization documents to include TEMOD
item.
(i.e., Objective is to get MTOE's/TDA's updated.) Following formal
authorization and requisition, the TEMOD item will be issued.
P3
Item removed from the field in certain applications; see applicable "E"
code/s.
