INSTALLATION OF ACCESSORIES ANTENNA INSTALLATION The supplied antenna provides good results over the entire frequency range of the transceiver. However, for enhanced reception on certain non-Amateur frequencies, you may wish to connect an antenna designed specifically for that frequency range, as the supplied antenna is necessarily a compromise outside the Amateur band, and cannot be expected to provide high performance at all frequencies. To install the supplied antenna, hold the bottom end of

INSTALLATION OF ACCESSORIES BATTERY CHARGING If the battery has never been used, or its charge is depleted, it may be charged by connect- ing the NC-88 Overnight Battery Charger, as shown in the illustration, to the EXT DC jack. If only 12 ~ 16 Volt DC power is available, the optional E-DC-5B DC Cable (with its cigarette lighter plug) or E-DC-6 DC Cable (plug and wire only) may also be used for charging the battery. A fully-discharged pack will be charged completely in 10 hours. Disconnect the N

INSTALLATION OF ACCESSORIES BELT CLIP INSTALLATION Connect the hanger to the rear of the VX-177, with the notch pointing directly up, using the supplied screw (Figure 1). Use only the screw included with the clip to mount the clip to the back of the VX-177. Clip the Quick-Draw Belt Clip onto your belt (Figure 2). To install the VX-177 into the Quick-Draw Belt Clip, align the hanger with the Quick- Draw Belt Clip, and slide the VX-177 into its slot until a click is heard (Figure 3). To re

INTERFACE OF PACKET TNCS The VX-177 may be used for Packet operation, using the optional CT-91 Microphone Adapter (available from your Yaesu dealer) for easy interconnection to commonly-avail- able connectors wired to your TNC. You may also build your own cable, using a four- conductor miniature phone plug, per the diagram below. The audio level from the receiver to the TNC may be adjusted by using the VOL knob, as with voice operation. The input level to the VX-177 from the TNC should be adjust

OPERATION SQUELCH ADJUSTMENT [ ] To set the squelch, press the F key, followed by the MONI switch just below the PTT switch on the left side of the transceiver. Now rotate the DIAL (outer knob) to find the lowest setting (“LVL 1” through “LVL 15”) that will just si- lence the background noise. Do not use a higher setting than necessary, or sensitivity to weak incoming signals will be degraded. Press the PTT switch momentarily when you’ve made the new setting; this will return you to normal

OPERATION TRANSMISSION Once you have set up an appropriate frequency inside the 430 MHz Amateur band on which the VX-177 can transmit, you’re ready to go on the air! These are the most basic steps; more advanced aspects of transmitter operation will be discussed later. To transmit, press the PTT switch, and speak into the front panel microphone (located in the lower left-hand corner of the speaker grille) in a normal voice level. The TX/BUSY indicator will glow red during trans- mission. To
