Re: [Elecraft] Dead K3 RX, no Power Out

Martin, I would try giving each of the TMP cables a slight twist. Secondly, I would remove and reseat the front panel board. No guarantee that will correct it, but it is a good starting point. 73, Don W3FPR On 6/11/2016 7:35 AM, Martin wrote: 'Crafters, i have a 7 year old K3 #28xx causing

Hi Todd, Has there been a power cut? No seriously, check if your rig is getting power OK. Always start at the Power Station and work your way forward. Check connectors and fuses. 73 from David GM4JJJ > On 15 May 2016, at 23:05, todd ruby wrote: > > This is a new and

This is a new and disturbing issue. I had just made 2 contacts one to Congo on CW on 15 one to Serbia on SSB on 20 and I was just monitoring a station and reading something when all of a sudden his signal went silent and I had no output power whatsoever! I did not touch the radio at all, it

Re: [Elecraft] Dead K3 all of a sudden

Unsure of what may be the issue, but it would maybe be a worthwhile thing to restore from your last good configuration that you stored with the K3 utility. If you do that and there is still a problem, then it is not something with your software setup and if so, the answer would be outside the

Hello I was just on 20M everything working perfectly. I went up to take a shower, came back down and now there is 0W output power, all TX calibrations have failed and I can’t hear any signals on any band. Would could possibly happened. Any ideas would be much appreciated, 73 todd WB2ZAB

My main K3 (s/n 3021) was working fine but suddenly wouldn't power up. Not sure if I had it on when I left the shack but when I came back hours later it was off. When tried to turn it on using the Power button, nothing. Power supply works fine with other K3 so that's not an issue. Not

[Elecraft] Dead K3 - Comes Alive!

Well sure enough, the buys at Elecraft (Thanks Harold!!!) shipped me parts overnight and my K3 came to life. They very smartly shipped a new Q2 (bad) and the K3 12DC Current Mod Kit. While my radio had the kit installed from the factory, the kit had two very important parts. D35 was shorted in

[Elecraft] Dead K3

Well after talking with support today, I returned home this evening and removed D35. Sure enough, shorted. Then plugged in the radio and tested it. Nothing. Made voltage checks around Q2. 13.8VDC at the source, 2.5V at the Drain and 2.5V at the gate. Gate stays at 2.5V (well drops to 2.4V)

So I was testing out my new K3 before I take it to J6 next week for a little DXPedition work. and after about an hour of operation.. it just quit. Dead as a door nail. has power to the back (checked) but never so much as the display activating. Any ideas? I SURE don't want to go back to that

Re: [Elecraft] Dead K3

If you can, check the resistance across the K3 12VDC IN Power Pole connections (after you've disconnected your Power Supply of course). On my K3, an internal zener-like diode (D28 on the RF Board) evidently gave up its life to protect the radio from an overvoltage, and evidently the failure

Re: [Elecraft] Dead K3

My guess from your 995 ohm resistance check, is a dead Q2 FDS6375. It will be interesting to see. I would post the K3 to Elecraft and have it when you get home. Good luck on the trip. Adrian ... vk4tux -- View this message in context:

Re: [Elecraft] Dead K3

Another possibility is that the /PWR_ON line that biases on Q2 is not being pulled low by the associated line to the Front Panel board due to an intermittent connection on connector J30. Maybe try disconnecting and then reconnecting the Front Panel board from the RF Board. 73, Dale WA8SRA On

I was able to do some diagnostic work to determine that D35 is shorted. How this could happen is a complete mystery? I've never had anything plugged into J11 (the 12V accessory out jack), so don't quite understand this. That is odd. About the only thing one would expect to cause that is an
