David, Set the radio for 5W in the TUNE menu first. Then press the tune button. I make all of my power measurements with my KX3 set to 5W and TUNE. John and I use these DL1s extensively. Google KN5L DL1 and read up on the diode characterization and further reading about its use. 72Myron WVØHPrinted on Recycled Data -------- Original message --------From: David Davis <kg6...@sbcglobal.net> Date: 6/7/2016 10:49 PM (GMT-07:00) To: elecraft@mailman.qth.net Subject: [Elecraft] KX3 RF out voltage measurements... I might have an RF out issue with my KX3 but I am not sure how to test it.
I have an Elecraft DL1 and a DMM that I figure I can use to check the RF voltages and verify the power out. However, I am not sure of the exact process on how to do this. If I am keying the mic on SSB do I need to speak into the mic to be able to measure the voltages or just key the mic with silence? I would assume I need to be speaking into the mic. The reason I ask this is because if I just key the mic with silence and the radio set for 10W with a input power supply of 13.5V DC I measure 4.7mv DC at the TP1 on the DL1 unit. If I speak into the mic I see voltages from 11 - 18V DC from the TP1 on the DL1 unit. It seems to me that I need to be speaking into the mic. I figure if I was checking the RF out in CW mode I would need to key the keyer in some fashion. I know this seems like an elementary level question but I would really like to verify the RF power out. Any information is greatly appreciated in advance. Thanks!
