FTM-400DR Cross-bandrules:· First off, the digital mode is disabled whencross-band is enabled. So forget this idea. I have not been able to figure outa way to make this work.· When you enable cross-band and the FTM-400DR is intransmit the microphone is hot. Unplug the microphonewhen you enable the cross-band mode.· With any cross-band situation, don’t try tocross-band two repeaters unless one or both have no repeat tail. If they bothhave repeat tails, it will cause the radio to see-saw.So, as a general ruledon’t try to cross band repeat 2 repeaters.· Prior to setting the FTM-400DR to cross-bandenable, first set the Frequencies, repeat shift, power, PL/DPL, TOT.· Turn off APRS Modem (In APRS menu)· When cross-banding is enabled, control head isessentially locked, no changes can be made to the radio except to turn off andor disable the cross band function.· If you cross-band onto a NBFM repeater and you areusing simplex as your other band make it also NBFM.· Make sure the power is set to either Medium orLow. Do not use high power. Remember to setpower on both A and B sides. · For new hams: You can notcross-band both A and B side in the same band, in other words, you must use twodifferent bands during this mode. Suggestions:· I strongly recommend that you invest in the YaesuSMB-201 cooling system for the FTM-400DR. It also fits the FT-8800 and theFT-8900.· If you leave the transceiver unattended in thecross-band mode, set the TOT (Time-out-Timer) . I would suggest 1-2 minutes. EnablingCross-band Mode
Set a 70 cm frequency in either the upper or lower display, using either theVFO or memory.
Set a 2 meter frequency in the other display, using either the VFO or memory.
Turn the FTM-400 off.
Press and hold the lower 3 buttons to the right of the display then press thepower button. “X-BAND Repeater” will be displayed between the upper and lowerfrequency displays, if the FTM-400 transferred into cross-band repeater mode.Now, you can enter a 222 mhzfrequency in the bottom display and you would have a one way repeat mode.Example, 223.5000 CSQ simplex on the bottom display and on the top (My repeater) 444.8250 DPL 172 , so myrepeater would work normal but it would also repeat everything it would hear on222.5000 also but, because the FTM-400DR lacks the ability to transmit on the1.25 meter band full cross-band repeat would be impossible.During an emergency (and withauthorization from the county EC) you could Cross-band a fire frequency onto a70cm simplex frequency. To have full cross-band capabilities you would need todo the MARS-CAP modification.Example: Top modeFire /Search and Rescue 155.1600 NBFM PL127.3And bottom mode(ham side) 446.0050 NBFM CSQ DisablingCross-band mode
Press and hold the lower 3 buttons to the right of the display then press thepower button. “X-BAND Repeater” will not be displayed between the upper and lowerfrequency displays, if the FTM-400 transferred out of cross-band repeater mode.
Returnthe frequencies to your preferences.
Turn the APRS modem on, if you run APRS. Mark A. Lacy –W5TXR
