The EE-105 Field Telephone

The EE-105 Field Telephone was used primarily in forward positions as a link backward from listening posts (LP) or observation posts (OP) to a platoon or company location via a switchboard such as the SB5 or BD71. The EE-105 is unique in that it can be operated as a standard EE8-type of field telephone or switch to a higher impedance in the EE-105 mode.
