FT-411 Modification FT 411 OUT OF BAND MODIFICATIONS. --------------------------------- 1) Open the front cover 2) Locate the C.P.U. unit (it is located on the front cover ). 3) Locate Jumpers 1,2,3 and 4 , These are the band setting Jumpers 4) Jumpers No 1, 2 and 4 should be disconnected ,and Jumper No 3 should be connected. 5) Close the radio . 6) Apply power to the radio and turn it on. The display will initialize with memory No 1 flashing and the frequency display will show 1.000 7) Now , adjust the display to the desired lowest receive frequency. When done ,press VFO. The memory CH will now show 2 flashing. 8) Adjust the display to the desired highest receive frequency. When done press VFO. The memory CH will now show 3 flashing. 9) Adjust the display to the desired lowest transmit frequency. When done ,press VFO. The memory CH will now show 4 flashing 10) Now , adjust the display to the desired highest transmit frequency. When done ,press VFO. The rig is now set for your programed band on transmit and receive. COMMENTS ------- 1) After the rig was programmed to the band and you want to change it to other ranges you will have to open the rig again and disconnect Jumper No 3 then to apply power to the radio, turn it on again open it again ,connect Jumper No 3 back and repeat from steps 5. Any comment and other information would be appreciated. disclamer: I have not tested or verified the above, proceed at your own risk. WA2ISE FT-411 MODIFICATION =================== I have this hand held, and by playing with it, I discovered a nice trick to increase its frequency coverage. It is so simple that you don't even have to open your hand held. All you have to do is: 1. Make sure that the power switch is off. 2. press the UP arrow and DOWN arrows together, at the same time. (those keys are also called A, and B.) They are located at the upper right side of the keypad) 3. Keep both buttons pressed while turning the power on. Now you can receive 130-174Mhz, and transmit 140-150Mhz CAUTION: When you do this modification the memories can be erased. 73 AVIAD, 4X6TL @ 4Z4SV MODS @ GBR. Subject: FT411 MODIFICATION VIA COMPUTER I was unhappy with the FT-411's "3" mode because the frequency had to be entered starting with the 100 MHz digit, and the ARS function would not work. I now use it in the "2" (normal) mode with the following mod. I used the "clone" mode to dump the FT-411's ram to a computer. It's 9600 baud, 1 start bit, 1 stop bit, CMOS logic. 544 bytes are dumped when the up arrow is pressed. Starting with byte $211 are the upper and lower transmit and receive frequencies, stored in BCD. I changed these to the limits I wanted. My FT-411's upper PLL limit is 195.4MHz, so I used 195 MHz. The lower limit MUST remain set to 130 MHz (magic number) or the keyboard entry of frequencies will start with the 1 MHz digit .VS. the 10 MHz digit. To put the data back into ram, just press the down arrow and send the new 544 bytes to the FT-411. You could also just clone an H.T. that has the limits you want. You cannot clone a mode "3" H.T. to a mode "2" H.T., however. The mode is contained in the first byte, which must match.

Ayhow I think it is not the end, and there are some more options.If you do have some more information about this Hand held, Please leave me a msg with it.
