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. Larry
From: Gayle Dotts via BVARC Sent: Saturday, 8 April, 2017 2:17 PM To: BRAZOS VALLEY AMATEUR RADIO CLUB Cc: Gayle Dotts Subject: [BVARC] Power supply Got a question on power supply for my Yaesu FT-920. The FT-920 manual says: 13.5V 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] http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Message delivered to [email protected]
