Vertex vx 180 manual

See page 79 for details. 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 the antenna, then screw it onto the mating connector on the trans- ceiver until it is snug.

Do not over-tighten by use of extreme force. When installing the supplied antenna, never hold the upper part of the antenna while screwing it onto the mating connector on the transceiver.

If using an external antenna for transmission, ensure that the SWR presented to the transceiver is 1. Under normal use, the FNB may be used for approximately charge cycles, after which operating time may be expected to decrease. If you have an old battery pack which is displaying capacity which has become diminished, you should replace the pack with a new one. To remove the battery, turn the radio off and. A fully-discharged pack will be charged completely in 10 hours. The NC is not designed to power the transceiver for operation reception or transmission.

Do not leave the NC connected to the transceiver for continuous periods in excess of 24 hours. Long term overcharging can degrade the Ni-MH battery pack and significantly shorten its useful life. Please be advised that the NC may contribute noise to TV and radio reception in the immediate vicinity, so we do not recommend its use adjacent to such devices.

As your battery discharges during use, the voltage will gradually become lower. When the battery voltage is becoming too low for reliable operation,. Connect the hanger to the rear of the VX, 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 Always replace all six batteries at the same time, paying attention to the polarity indicated inside the case.

The FBAA must not be used with rechargeable cells. Note that the power output and battery life will be much shorter when using Alkaline AA cells. They should be considered an emergency backup power source only, for this reason. You may also build your own cable, using a fourconductor miniature phone plug, per the diagram below. Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent voltage spikes from possibly damaging your transceiver.

See page 62 for details regarding Battery Saver setup. Be sure the Battery Pack is installed, and that the battery is fully charged. The current DC supply voltage will be indicated on the display for 2 seconds. After this 2 second interval, the display will resume its normal indication of the operating frequency.

Clockwise rotation increases. Do not use a higher setting than necessary, or sensitivity to weak incoming signals will be degraded. This feature allows you to set the squelch so that only signals exceeding a certain S-meter. This feature will keep your radio quiet until a call is received from a station sending a carrier which contains a matching subaudible CTCSS tone. Or, if your friends have radios equipped with DCS Digital Coded Squelch like your VX has, try using that mode for silent monitoring of busy channels.

Rotation of the DIAL outer knob allows tuning in the pre-programmed steps established for the current operating band. Clockwise rotation of the DIAL causes the VX to be tuned toward a higher frequency, while counter-clockwise rotation will lower the operating frequency. This feature is extremely useful for making rapid frequency excursions over the wide tuning range of the VX The desired operating frequency may be entered directly from the keypad.

Details regarding sub-band setup may be found on page If you wish to reverse the direction of the scan i. The scanning direction will be reversed.

To revert to scanning toward a higher frequency once more, rotate the DIAL one click clockwise. The scanner will stop when it receives a signal strong enough to break through the Squelch threshold. Press the PTT switch momentarily to cancel the scanning. This only stops the scan; it does not cause transmission to occur. See page 36 for details regarding Scan Operation. 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.

To return to the receive mode, release the PTT switch. During transmission, the relative power level will be. Press the [F] key, then press the [3 LOW ] key. Each side of is referred. In most cases one side has. Your cooperation in pointing.
