Oscar, I don't know the specifics of your particular amplifier - BUT - The K3 KEYOUT can handle up to 200 volts DC (positive only) at 5 Amperes.
You can easily measure the requirements of any amplifier with a DMM. First set it to read voltage and measure the open circuit voltage (to the amplifier ground) from your amplifier KeyIn (or PTT IN or whatever it is labeled). If that voltage is positive and less than 200 volts, check one passes. Then configure your DMM to read current. Connect the positive probe to the center conductor of the amplifier KeyIn jack and touch the negative probe to ground (that should operate the relay in the amplifier). If the current is less than 5 Amps and the voltage test succeeded, then the K3 can key that amplifier. 73, Don W3FPR oscarv...@speedy.com.ar wrote: > I need to connect my amplifier fl2100z with K3, direct connect to key out to > RY the amp FL2100Z or I have to put a relay, please i need help and thank you > very much.- > > LU1XS, Oscar > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
