Upload by Dipper

FYG-4 is a microprocessor-controlled channel data programmer for Yaesu FTL-2001 VHF and FTL-7002 UHF land mobile transceivers. It enables programming simplex or semi-duplex channel frequencies and EIA standard RS-220-A subaudible CTCSS tone codes when used with the FTS-14 tone squelch unit. The device supports manual programming or automatic programming via data transfer between the FYG-4 and preprogrammed transceivers, with EEPROM retention for indefinite reuse. It can be powered by six UM-3 dry cells or 9V DC via the NC-9 charger. The manual details controls, connections, battery/power setup, uploading, altering, displaying, channel reprogramming, error recovery, and programming examples.

The FYG-4 can be either manually programmed,or automatically pro-grammed by transfer of data from a preprogrammed transceiver.Ineither case,data in the FYG-4 can be freely modified,and then trans-ferred back to any number of transceivers to change or initially programthem with new data.Once programmed,data is retained by an EEPROMin the FYG-4 indefinitely. The FYG-4 can be operated portably by installing six UM-3 dry bat-teries,or from the AC mains by using the Yaesu NC-9 battery chargeras a source of 9V DC.A shielded cable is provided for data transferto and from transceivers. CONTROLS AND CONNECTORS # (1)IN/OUT Jack This 3-contact jack accepts data input from a transceiver to programthe FYG-4,and provides output of FYG-4 data to a transceiver.Thesupplied programming cable connects between this jack and the micro-phone jack of the transceiver. # (2)DC IN Jack This 2-contact jack accepts 9V DC for operation from the NC-9 Charger,when used as a power supply.When this jack is used the internal drycell batteries are disconnected (the NC-9 does NOT function as acharger for the batteries in the FYG-4). # (3)POWER ON/OFF Switch This switch turns the FYG-4 on and off.When operating from the internal batteries,make sure to switch the FYG-4 off when not in use. # (4)TX/RX Switch On semi-duplex channels,this switch allows confirmation of the transmitfrequency on the display. # (5)Display This 7-digit LCD shows frequency,channel number and CTCSS tonecode: # (6)Keypad These 20 keys are used to enter and check programming data in theFYG-4.Most keys have two functions,depending upon the mode ofoperation of the FYG-4(Writing Data,or Simulating Operation).Norm-ally,if the FYG-4 POWER switch is simply turned on,the keypad anddisplay simulate transceiver operation.However,if the key isheld down while the POWER switch is turned on,and "AAAA"is thenkeyed in,the keypad is activated for writing data. | KEY | Simulate mode | | Write mode | | Display | | --- | --- | --- | --- | --- | --- | | | Number 1 | | Number 1 | | 1 | | 2 | ～0 Numbers 2,3,4,..0 | | Number 2,3,4,…0 | | 2~0 | | | Step Channel Down | | Hex Number A | | R | | | Step Channel Up | | Erase or Skip Data | | | | B

FAQs

What transceivers is the FYG-4 designed to program?

The FYG-4 is designed for Yaesu FTL-2001 (VHF) and FTL-7002 (UHF) land mobile transceivers.

What can be programmed with the FYG-4?

It can program simplex and semi-duplex channel frequencies and RS-220-A subaudible CTCSS tones when the FTS-14 tone squelch unit is installed.

How does uploading and downloading work in the FYG-4 process?

Uploading transfers data from a source transceiver to the FYG-4, altering adjusts the FYG-4 data as needed, and downloading sends the altered data from the FYG-4 to target transceiver(s).
