JULY 25, 2006 Equipment Authorization Division Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 FCC ID: H4JVT-4E150 Product Name: VT-4E150 VHF TRANSMITTER Compliance with 47 CFR Part 90.203 (g), (j)(3) Pursuant to 47 CFR Sections 90.203(g) and (j)(3) of the commission’s rules we hereby certify that the above listed transmitter is fully compliant with these guidelines for the following listed reasons. The VT-4E150 transmit frequency is capable of being programmed within the range of 136 to 174 MHz via an external USB connection and Radio Services Software (RSS) package, which is made available only to service and/or maintenance personnel. The narrowband setting of this equipment operates from 0.5 to 8 Watts and meets a spectrum efficiency standard of one voice channel per 12.5 kHz of channel bandwidth in analog transmit mode. In the digital transmit mode, the equipment supports the minimum data rate of 9600 bits per second per 12.5 kHz of channel bandwidth.

5. Tune-up Procedure Transmitter programming is performed with the PC-based Radio Service Software (RSS).. The RSS runs under Microsoft Windows 95/98, 2000, ME, XP, or NT and allows the Transmitter to be programmed for operating frequencies, CTCSS and DCS signaling, and modulation type. Analog test modes may be selected by the Radio Service Software, as well as test modes specific to P25 digital operation. Transmitter settings are divided into two categories, Transmitter Wide options, which apply to all channels, and Channel Wide options, which can be programmed differently for each channel. When the Transmitter menu is selected from the main screen, both the Transmitter Wide and Channel Wide options for the current channel are displayed. The RSS may be used to save a Transmitter configuration to disk. This function allows the user to save a “standard” configuration, and use it as a starting configuration for all Transmitters. An archive of configurations from each radio system in operation may also be kept so that replacement radios can be programmed easily. 5.1. Transmitter Wide Settings Several options may be set which affect the operation of the Transmitter on a global basis. 5.1.1. Frequency Band There are four Frequency Bands available for Transmitters: VHF 136-174 MHz (0.5-8.Watt) UHF Low Band 380-406 MHz (0.5-8.Watt) UHF Mid Band 406-470 MHz (0.5-8.Watt) UHF High Band 470-512 MHz (0.5-8.Watt) When the Frequency Band is changed, the Frequency field in every Transmitter channel will be changed to the lowest frequency in the band. 5.1.2. Unit ID This field contains the unique Transmitter unit ID in Hexadecimal. (There is no need to enter an initial ‘$’character.) The default value is $1. The spin button to the right of this field allows you to incrementally change the ID. This unit ID will be transmitted in the source ID field along with every P25 voice frame if the transmitter is keyed using the Microphone PTT and each Transmitter should have a different number. 5.1.3. Secure Hardware Equipped This setting is not used for Repeater Transmitters, but is used for Daniels P25 Base Transmitters. Correct repeater operation does not require that an encrypted signal be decrypted. 5.1.4. Holdoff Delay This feature is to allow the use of a Tone Panel in analog mode. When enabled, it prevents the tone panel signal from interfering with the audio signal. The transmitter is activated 250ms after the rear connector PTTs (or the microphone PTT) are keyed. When disabled, the transmitter is activated immediately after the rear connector PTTs (or the microphone PTT) are keyed. This is the default configuration. 5.1.5. Hang Time Hang time is a selectable time delay, which can be enabled to keep the transmitter keyed after its PTT input is released. It can be used to keep an RF channel open in low signal conditions when the receiver might by squelching intermittently. It is also commonly used at the end of the transmission to keep the transmitter keyed long enough to provide confirmation that the repeater has been activated by mobile radios. The duration of the hang timer is selectable in 250ms increments from 0 (disabled) to 3.75 sec. Note that the Hang Time is applied only when the radio is keyed by the ANALOG_COR* or DIGITAL_COR* inputs, not from the front panel Mic connector or the PTT signal from the M-3 subrack. 5.1.6. Squelch Tail It is possible to add a burst of noise (a “squelch tail”) to the end of each transmission. This will occur for the duration of the hang time. When the transmitter is used in a repeater configuration in digital repeat mode, it may be difficult for mobile radio users to hear that they have successfully “hit” the repeater, since P25 radios usually operate in a “silent squelch” mode. The squelch tail noise is an audible indicator that the repeater was indeed keyed. Note that the squelch tail noise is applied only when the radio is keyed by the ANALOG_COR* or DIGITAL_COR* inputs. It is not applied when the transmitter is keyed by the PTT signal from the MT-3 subrack nor from the front panel Mic connector. In addition, if the radio is keyed again before the hang time has expired, the squelch tail noise will not be sent until the hang timer is set again by removal of the keying source. 5.1.7. Timeout Options The transmitter provides a selectable timeout timer for each channel, which causes the transmitter to be de- keyed after the selected interval of continuous transmission has been completed. Two transmitter timeout values are provided, and one of the timeout values may be used in each of the 32 programmable channels. The range of values is from 15 to 465 seconds in increments of 15 seconds, or Infinite Time may be chosen. These selected Timeouts can then be used in the Timeout Value field in each Transmitter Channel Setting. These fields are used to program the parameters for a single Transmitter channel only. There are 32 different available channels labeled A1 - A16 and B1 - B16. The parameters for each channel are independent of parameters in other channels. 5.2. Channel Wide Settings The transmitter may be programmed with up to 32 channels, each with a different frequency, channel bandwidth and modulation type. The channels are arranged in two banks of 16 channels each, referred to as Bank A and Bank B. In this manual, a specific channel is referred to by its bank and channel i.e. B12 would refer to channel 12 in bank B. The following are all the settings that may be programmed on a per- channel basis. 5.2.1. Channel Name Each channel may be assigned a text name of up to 11 characters. The name is stored in the radio, but is never broadcast. It is provided as a means of identifying the channel during configuration. The channel name will default to the bank and channel number (i.e. “A1” for bank A, channel 1). 5.2.2. Channel Type Each MT-4D Transmitter can be programmed in analog only, P25 digital only, or mixed mode. P25 signaling is a purely digital mode, compatible …
