Re: [Elecraft] K3 - No RF output - Fault resolved

Very many thanks to everyone who responded to my request for help. Happily the fault turned out to be something very simple. Rob at Elecraft suggested the LPA FETs may have failed as the current measurements I had taken indicated the FETs were not drawing the bias current they should be. I checked

Hi Bill,The rig does not produce any RF out in any mode. Everything looks normal on the display, LEDs etc, the rig keys via mic or paddle but just no RF.Some have suggested a bad internal cable connection or bad board edge connector. I am working my way through those.

[Elecraft] K3 no RF Output

Dear Readers, i made a water damage of my K3. Meanwhile Receiver is working again, after some repairs. But there is still no RF output. Main symptom is, that in case of TX (key down in CW) i find at J7 (8.215 MHz TXIF1) a 8.230MHz signal, but no signal passing the filter, expected

Re: [Elecraft] K3: Low RF output only on 30 meters

Scott, Try running TX Gain Calibration with K3 Utility. If that fails, try running it on 30 meters manually (see the manual for the procedure). If it still fails contact Elecraft K3support. 73, Don W3FPR On 1/25/2016 12:30 AM, Scott Manthe wrote: Hello to the list! I fired up my K3

Hello to the list! I fired up my K3 tonight for the first time in months to try to work K5P and the VP8 expeditions. Thing seemed to be working fine until I tried working the VP8 on 30 meters. I noticed while sending that I didn't have much output on 30 meters. Investigating, I get output

That should read KPA3, not KPA100. On Mon, Jan 25, 2016 at 12:30 AM, Scott Manthe wrote: > Hello to the list! > > I fired up my K3 tonight for the first time in months to try to work K5P > and the VP8 expeditions. Thing seemed to be working fine until I tried > working

[Elecraft] K3 No RF output

I am getting 0 RF output from my K3 on all bands regardless of the commanded power level. Pressing the TX button results in -- where the SWR would normally be displayed. Any suggestions or ideas on how to resolve this issue are greatly appreciated. Thanks Gregg w6izt

Re: [Elecraft] K3 No RF output

It means TX Inh(ibit) has been activated. Check your menu setting. 73, Rick, WA6NHC iPad = small keypad = typos = sorry ;-) On Nov 9, 2014, at 10:14 AM, Gregg W6IZT gregg.w6i...@gmail.com wrote: I am getting 0 RF output from my K3 on all bands regardless of the commanded power level.

Todd, I experienced the same problem a couple of months ago. I never noticed a fault, but maybe it did it, and I didn't notice. I emailed Gary (supp...@elecraft.com) and tried the EE INIT including reloading previously saved configurations. I ended up sending the radio (S/N 3598) in. Keith
