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

Have you tried doing a TX GAIN calibration? It will likely fail given what you are seeing but it's another step to try. GL & 73, Brian, K0DTJ > On Apr 9, 2018, at 18:11, Martin Sole wrote: > > Hi, > > I can see output at the XVTR OUT jack. Using direct input on the

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

[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

Press and hold the right side of the band-switch over "Test" and make sure you are not in test mode. You should see the words: "TX TEST" or "TX NORMAL" It should say "TX NORMAL". 73s and thanks, Dave NK7Z https://www.nk7z.net On 04/09/2018 08:31 AM, Martin Sole wrote: Hi, My K3 died

Hi, My K3 died today, somehow. The radio works fine on receive and appears to transmit just there is no power indication on my external meter or on the front panel when pressing TUNE. There is ALC indication but no power out indication.The only thing I did different was to switch off the
