To use supply the radio with 12 volts you would have to use a power supply such as an Astron which can be purchased at Ham Radio Outlet and other ham radio shops, you can get their number on the internet. The 110 AC to 12 volt DC is not the problem..it requires the amperage to make the radiois work.... You can use a 12 volt battery and use it for a maybe an hour without charging....the radio will not work with a car battery charger... Hope this helps

I have a KENWOOD TS-940SAT HF Transceiver that powers up with the TX indicator on, no power output and no receive.


Very little information about the situation of the transceiver is provided, it might be a complex one. The Kenwood TS-940SAT features a built-in automatic antenna tuner covers the amateur bands 160 through 10 meters. It is advisable for you to reinstall the transceiver and follow the right set up step to see if it works out eventually.

How much current must the external power supply be able to provide?


To run an HF transceiver (100 W), the radios normally want to see up to 20 - 35 watts of power available at 12 volts. You earlier referenced the FT-990 HF transmitter, which takes a normal AC voltage input from a line cord. Normally a 20 amp circuit would suffice. Since you did not specify if the radio has the internal heavy duty internal AC switching power supply. For an 110 V connection, the unit requires an 8 amp fuse, and 4 amp for 220. I have included a link where you can download the manual for reference: http://www.download.n7tgb.net/yaesu/FT990/FT-990_Manual.pdf

My radio cuts out completely. Wait ! minute and repress the power button, radio back on.


sounds like the power supply. Check all your connections and wires just in case. But it REALLY sounds like the power supply.

What could cause Transceiver to shut when power output is increased over 40 watts?


My first guess would be that you have a bad/poor antenna,coax, causing high reflected power, next would your power source. You will need a 25A or higher rated power supply, with clean 13.5V power to run at the higher power levels. Meter the power supply voltage when you xmt at a lower power level, maby 30w, watch for drop in voltage. If voltage drops (some) at 30w, most likely supply won't hold voltage up at your 40w and higher power levels.
