  General Information about the Yaesu FT-7100  
The Yaesu FT-7100M dual band mobile brings you the ruggedness and operating ease of our single band mobiles and the convenience of remote head mounting capability in an all new design. Extended receive coverage provides monitoring of both public safety and the VHF air band [AM]. The power output is 50 watts on 2 meters (50/20/10/5 W) and 35 watts on 440 MHz (35/20/10/5 W). Despite its compact size, the FT-7100M has a large 2.3 x 0.9 inch dual frequency display. Simultaneous dual receive on two different frequencies, in band or cross-band is supported. (Cross-band repeater function is not available). Separate volume and squelch are provided for each band. A handy mute feature prevents "competition" between the two receivers by automatically muting the sub-receivers audio when a signal is received on the main receiver.

The main memory of the FT-7100 includes 240 channels (120 channels per band). Plus you get 5 pairs of programmable band limits and a one-touch Home channel on each band. Each memory stores frequency data plus CTCSS or DCS frequency and operating status, and repeater shift is also memorized. A six-character alphanumeric label may be appended to each memory (upper display field: 5 characters). Sophisticated scanning is also supported. You get: VFO scan, Memory scan, Programmable Memory scan (PMS) with user-defined limits, and you designate can channels to be skipped during memory scan. You also get Yaesu's unique Smart Search™ automatic memory loading system, which sweeps a portion of the band, automatically loading active frequencies into a special 50-channel Smart Search™ memory bank. You also get 3 priority channel modes.

The FT-7100M features Yaesu's ARTS™ Auto-Range Transponder System, important in search-and-rescue applications. ARTS provides a "hand-shake" with other ARTS equipped transceivers and displays out of range or in range. A 6 character CW ID is also provided for your station every ten minutes during ARTS operation. The FT-7100M is ready for 1200/9600 packet operation with the addition of the optional CT-39A packet cable.

Only 5.8x1.9x7 inches. This radio comes with the MMB-36 mobile mounting bracket, MH-48A6J DTMF hand mic, double fused 12 VDC power cord,.
