Re: [Elecraft] K3 apparent PA failure Update.

Martin, Contact Elecraft support. I purchased a pair of the same MOSFET's a couple of years or so ago when my K3 did the same as yours... Unfortunately mines done it again just recently, so this time I'm ordering a few spares. 73 Matthew VK5ZM On 10 April 2018 at 14:32, Martin Sole

Re: [Elecraft] K3 apparent PA failure Update.

Hi, Both output devices in the LPA, Q4 and Q5, RD15HVF-1, show low ohms gate to source, one is 2.4 ohms the other 4.6 ohms. Anyone have a recommended source? I don't think these are available locally, I'll need to get a couple shipped in from US or elsewhere most likely. Thanks Martin,

Re: [Elecraft] K3 apparent PA failure

Hi, I can see output at the XVTR OUT jack. Using direct input on the LP-100A meter it shows output varyng in sympathy with the output level control  and a setting of L 1.00 gives pretty much 1dBm on the LP-100A. Lowest I can read is around -12dBm and highest about +3dBm before the K3 switches

Re: [Elecraft] K3 Apparent PA failure ?

Hi, Well I've been through all of the operational settings. CONFIG : TUN PWR is set to NOR and I can vary the power with the power control but the output meter display stays at 0.0 and the VSWR displays only - - . I had a settings save from about a month ago but uploading that hasn't changed

[Elecraft] K3 apparent PA failure

Had the same thing happen here to my K3s but only with the high power board. The low power 0 to 12 watt board continued to work normally. Tried a transmit gain calibration with no effect. I sent it back to Elecraft and they replaced both the low and high power boards with revisions they deemed

Re: [Elecraft] K3 Preamp 2

Barry is in VK. If he operates from the middle of nowhere, local noise is nonexistent and local activity is extremely sparse. It means you hear lots of weak stations, most of which you have little chance of working unless you have good antennas and run power. So preamp is a plus in receive but it
