Re: [Elecraft] KPA1500 RELIABILITY

Of the 5 people I know with the KPA1500, 3 of them have made a return trip for LDMOS failure. Also had my RF-Kit blow up twice. Will have to fix my old Henry 3k! Frank W2YK -Original Message- From: Wes Sent: Oct 31, 2022 6:02 PM To: Subject: Re: [Elecraft] KPA1500 RELIABILITY In

Re: [Elecraft] KPA500 Issue

Jim,.   I use the "1A2R" (one amp tw0 radios) from 4O4A.  I have two rigs share my KPA1500.  However, if the rigs are on different bands, you do need to rely on frequency sensing by the amp.  Not sure if the KPA500 does that.     GL Frank, W2YK   -Original Message- From: James Bennett

[Elecraft] KPA1500/GainLow/Input Pwr

Hi, My KPA1500 just started needing a lot more drive (2X) to get 'normal' output. I normally need 25-30 watts drive to get ~1k out. Now I need about 60W. I get two kinds of alarms, depending on how I test the situation, either a red "Gain Low' or a yellow 'Input Pwr'. If I drive with a
