FROM INTERNET GOOGLE SEARCH Re: hidden menu I'm preparing a complete file on it... Just working on it now. So it is far from being complete, as you can see... Just read hereunder the introduction of this chapter. Regards. Eric, ON6CV --------------------------------------------------------------- Some interesting things about modifications for the FT-2000. The goal is not to recreate the mods.dk website here… But there are some parameters that are maybe interesting to change or tweak… As some of them are in the service menu, this is a hidden menu accessible for maintenance by an qualified technician, it's a good thing to write down ALL the settings in this menu. If something goes wrong with a parameter, then you can go back thanks to your paper ! So any modification made to this menu could be dangerous if you don't know what you're doing ! Just be careful exactly like the Windows XP / Vista registry file. WARNING & DISCLAIMER ! NEVER execute the full reset procedure on this service menu ! As long as you don't have another radio or the complete list of your settings… It's like killing the radio ! Do all the modifications at your own risks, I could not be responsible if you're doing something wrong, keep away from any mods if you're not sure ! HOW TO ACCESS THE HIDDEN / SERVICE MENU ? Switch the radio OFF Push the 1 + 2 + 3 frequency buttons on the front panel while POWER ON This will bring the service menu on the screen You can still hear some stations if you were on 7056 khz for example, but as you turn the main VFO A knob, you'll hear different things, mode is changing, antenna, filter selection, … That's a normal behavior, don't enter the panic mode J. Every changes made to this menu will be saved exactly the same way as the normal MENU accessible with a button from the front panel. Just push this MENU button for 2 seconds to save and exit the hidden service menu. A) Changing the fan speed You can reduce a bit the speed of the blowing fan inside the radio. Mine was very noisy and exhibit a high pitch noise that was annoying to my ears. Simply reduce the value from 160 to 120 in the menu item #B07. Be careful not to slow down too much the fan or you'll have troubles with the inner temperature. Never reduce this value too far, the blower will not be very effective if the speed is too slow and it could be dangerous for your radio. B) Reducing the IF stage gain to lower the noise floor This is a very easy modification to do, no need to have laboratory test equipment. In the FT-1000MP MARK V series, you have the same thing into the service menu too but it was a general setting for all bands. In the FT-2000 you can adapt the IF gain for each band from 160 to 6m. If you're happy with the noise floor of your rig, don't modify this… If you're curious, then you can play with these values… And always keep the original values on a sheet of paper if you're not happy with your settings. In the service menu go to search for these values and note every number before doing some experiments. B11 = IF Gain for the 160m band B12 = IF Gain for the 80m band B13 = IF Gain for the 40m band B14 = IF Gain for the 30m band B15 = IF Gain for the 20m band B16 = IF Gain for the 17m band B17 = IF Gain for the 15m band B18 = IF Gain for the 12m band B19 = IF Gain for the 10m band B20 = IF Gain for the 6m band If you have a number of 97 for example at B11, if you turn the VFO B knob clockwise (to the right) you will increase the value 1 by 1. A higher number will lower the IF Gain on that band only 1dB at a time. Some hams found that the receiver is 10dB too hot on each bands… So, increase each number by a value of 10 as a good starting point. Personally I increased all the values with a number of 15. Don't forget to save your new settings pushing the MENU button for 2 seconds. If you want to spend some time on each band to do the adjustment… Put the rig in the first 160m band While listening to the weakest signal that you can find on that segment POWER OFF the FT-2000 POWER ON while pushing the 1 + 2 + 3 buttons Access the hidden service menu Go to B11 IF Gain for the 160m band When you are there, observe the screen, you will see that AMP1 is ON Press IPO button until it shows ON (bypass of the 2 preamps) Adjust the VFO B knob till signal to noise ratio is what you want Save the new values (Push MENU for 2 secs) The new settings have no effect on the S Meter calibration, but signal seems to be a bit lower as the noise floor. Reducing the noise floor didn't increase the signal / noise ratio but less noise is preferred for long hours of operations or for SWLing. Again, try this by yourself… If you think it's not useful… re- introduce your backed up settings and be happy. C) The Complete Hidden / Service Menu Remark : the default values are only valid for MY rig ! Depending on the components and final factory adjustments, your values may be different. Do not take MY default values as the default values for all FT-2000 coming on the market. After accessing the hidden service menu you'll browse a huge list of parameters. Change one parameter at a time and write down any changes on a paper… If anything goes wrong, re-install the previous value and save the menu.
