MFJ sells one for about $60 + tax and shipping (MFJ-262B, PL-259 connector) . This one is convection air cooled and will take 100 W. for about 10 Sec. continuous and is DC to 1 GHz 1:1 SWR. Get this one or one like it. 73s, Gary Sitton, K5AMH [email protected]<mailto:[email protected]> On 4/11/2017 11:32, Larry via BVARC wrote: Gayle, What’s your SWR? If you’ve got hi SWR the output fold-back circuitry will reduce output. and you will only see full output in a key-down (CW) mode. Voice has a low duty factor so you would only see a low average power output in that circumstance.

The FT-920 manual says: 3.5V DC….Rx(w/signal) @2.5A, Tx (100W) @22.0A. My current power supply is a MFJ-4225MV 25A switching power. Is this MFJ will power the Yaesu but I don’t really see the 100W on output Tx, although the amp meter on the MFJ shows 6-12A while transmitting running low to high on the RF PWR knob on the FT-920. Do I need to increase the power supply?? Please advise. Thanl you, Gayle Dotts KF5LVZ ________________________________ _______________________________________________ BVARC mailing list [email protected]<mailto:[email protected]> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Message delivered to [email protected]<mailto:[email protected]> _______________________________________________ BVARC mailing list [email protected]<mailto:[email protected]> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Message delivered to [email protected]<mailto:[email protected]>
