Kenwood TS-480sat - the hidden menu 

Hate to burst your bubble, but the service manual says this is only meter calibration. Has nothing to do with power increase.

This is dum, do not modify those values... you are ruining your transceiver, this are calibration values and you need proper equipment and procedures to get them done. Do not be naif.

Cześć Uwe.Jak byś po polsku napisał co zrobiłeś i co jest po tym Nastawieniu.Marek SP5XZM.

Hi dear. Here IU7KTD from italy. please would u be so kindly to show me how you work with automatic tuner, what i have to set before use at from menu and so on...??? thank you so much and 73

I did not put it on 156 but crack it up to 199 😈 now its 1 Kilowatt!!

The hidden menu is the "service menu" and unless you want to start splattering all over the band, LEAVE WELL ALONE.

Service menu access is absolutely idiotic thing to do by average user. You need good quality measurement equipment and ability to use them. Would not be bad if they are calibrated every now and then.

my 480 actually ran 100 watts out of the of the box.

The best setting is 255 in all power settings.

Yep, it's probably only meter calibration. After that I still have 100 whiskey out, but finally my radio show me 100 watts. Thank you Dziekuje

I put mine on setting "200" for SSB phone use. No damage at all. but do not use full power on FM or CW then because is more than 160 watts.

El menú de la kenwood ts-480 sat es el mismo que kenwood ts-480hx gracias por su respuesta

Bonjour, es que vous avez vérifié sur un WATTMETER ? car c'est peut être un étalonnage du vumètre que vous avez fait des les menus cachés merci de répondre.

i just bought a 480 from a friend that ''passed'' ''''it was in use '''''what is th first thing you recommend

thanks Great video 73 from kb2uew

tnx for info But evertything is Ok than hıdden menu 77-76 which button change and OK ?

everythink will be fine but ... on the low power the s meter show differents.for the simples if i have 30 w s meter show 30 but if i put 65 w meter show 100 w ....

Uwe, after such an operation, the display shows 60 watts (%) of the transmitter power 100 watts and is adjusted smoothly to 0 (5) watts, but the display only starts to change from 60 to that on the display there are no changes.

Try to setup this menu unfortunately it stated checksum. Not sure what wrong

Thank you for the heads up!

Good to know about the hidden menu. Thanx. 73'de SM6YZR

I'm wondering why you were only getting 50 watts RF output to begin with from a 100 watt transceiver?

Good video I have the HX version and its calibrated to 250 plus watts, draws 39 to 42 Amps

KENWOOD TS-480 INSTRUCTIONS Pdf Download | ManualsLib INSTRUCTIONS FOR INCREASING OUTPUT POWER OF THE KENWOOD TS-480: Kenwood in the "HX" version, took the space dedicated to the automatic antenna tuner in the "SAT" version, and installed a second power amplifier that duplicates that of the 100W version, then both amp power is add using a toroid splitter at the output. These two amp boards use as final transistors the 2SC2732, rated for 80 wts output each, so having 4 of them on these two boards the radio is be capable of making 320 wts PEP. Do not run them at maximum power, instead a "safe" level of power will be around 260W so each transistor will be running 65W. Knowing this important factor about the circuit design, let's make the adjustments: First, build what Kenwood calls an "adjustment jig" which is basically the six pin Data plug that came in the box with the radio. You will have to solder a small piece of wire from pin 3 to pin 6 of that plug, put the metal and plastic covers back and make it ready to be plugged at the rear of the radio in the accessory jack labeled "DATA". Now do the following procedure to get the adjustment menu: Insert the assembled plug into DATA connector located on the transceiver front panel 2- Turn the radio on while pressing the MIC and the NR keys to enter the adjustment mode; then you will see immediately the Menu # 00 in a small window left to the freq display that normally is used to show the memory channel. 3-Remove the DATA plug from the transceiver when the Menu number window appears. 4-Now rotate the MULTI knob clockwise slowly to Menu # 24; you will see in that menu numbers between 164 and 166 which are the factory default to set the 200W.To increase the power use the small arrows that normally you use to move bands up or down and set the number to 175 and check the power output using a wattmeter and a 50 ohms dummy load, maybe the final number for you might be different than the one obtained in our radio. Also it will depend on how much power you want. In our case the radio was giving out 260W key down(CW) and around 250W on voice peaks. 5-Now to write the new setting to the EEPROM go to menu # 76 using the same MULTI knob.You will read EEPROM on the display. 6- Move the up arrow, the one used to move bands, and immediately the display will show "good" meaning the data was entered to the EEPROM. 7-To exit the adjustment mode,just click on the MTR key and the job is been done. Warning Do this totally at your own risk. Don't exceed 260W on CW because if your antenna system is more than 1.5 swr you might damage your final amp and void the factory warranty. Be sure you have a safe antenna for this high power safe antenna for this high power

Hello, the connector that you insert without a cable inside has an internal bridge or is it just the pure connector for the radio to detect something inside? Thank you
