From: 4X6TL@4Z4SV Hello to all the owners of the FT-411 OF YAESU, I have this Hand held, and by playing with it, I discovered a nice trick to increase it 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 arrow together, at the same time (those keys are also called A, and B. and they placed at the upper right side of the keyped) 3. Keep pressing both buttons and turn the power on. That's all. Now you can receive 130-174Mhz, and transmit 140-150Mhz CAUTON: When you do this modification the memories can be erased. 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.

From: 4X6TL@4Z4SV Hi everybody. Here is some new interesting info about the FT-411: 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. Good Luck Aviad 4X6TL@4Z4SV disclamer: I have not tested or verified the above, proceed at your own risk.
