[Elecraft] What is K3 Fault 6?

I have seen this a couple of time when my KPA1500 throws the Excessive power input fault.  Can't find any definition in my K3 docs. -- 73, Pete N4ZR __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help:

Re: [Elecraft] What is K3 Fault 6?

Hi Pete, Check the KPA1500 fault log using KPA1500 Utility. Amp fault codes starting with "6" (such as fault 60) are displayed on the K3 as fault 6. 73, Wayne N6KR > On Mar 30, 2024, at 6:42 AM, Pete Smith N4ZR wrote: > > I have seen this a couple of time when my KPA1500 throws the

I built a QRPGuys noise bridge a while back. Fun kit. https://qrpguys.com/test-equipment 73, Brian, K0DTJ > On Mar 30, 2024, at 13:43, Bruce Rosen wrote: > > I see that Elecraft no longer sells the N-GEN wide band noise generator. > My N-GEN, which I built in 2010, seems to function no

Re: [Elecraft] N-GEN replacement

Bruce, You might try replacing the diode in the N-Gen. If that does not work, then look at the Noise Generator that N0SS (SK) published.  It is available at http://www.mmccs.com/mmarc/n0ss/noise_source.pdf. If you have board etching capability, the board shown is full size - although you can

[Elecraft] Elecraft K3 boards needed

I am looking for some older K3 boards that most of you have upgraded,and probably will never use. Ksyn3 Kant3 Kxv3 Kxv3a Kio3 I could use 5 of each to start. Please let me know what you have sitting around. Thank you, Larry K6ro www.LSRarecoins.com 310-710-2869

Did the fault occur immediately after a band change?  I occasionally see a slight  power overshoot from my K3S on the first transmission after a band change.    Perhaps a transmit gain calibration is in order.   I use the K3 Utility for this purpose and a known good 50 ohm dummy load.   The

[Elecraft] N-GEN replacement

I see that Elecraft no longer sells the N-GEN wide band noise generator. My N-GEN, which I built in 2010, seems to function no longer, so I'm looking for a suitable replacement. Kit form is fine. Any suggestions would be appreciated. - Bruce K1FFX

The 2N5235B is .15 cents + postage at Digikey. Better hurry they only have 14,500 left. 73, AK5X-Bill Sent from my iPhone > On Mar 30, 2024, at 4:56 PM, W3FPR wrote: > > Bruce, > > You might try replacing the diode in the N-Gen. > If that does not work, then look at the Noise Generator

[Elecraft] Elecraft CW Net Announcement

Good Evening,    Some weeks nothing goes right, this was not one of them. Light rain then sun and mild temperatures.  More flowers and more birds.  Snow is melting above me so streams are full.  The ground was dry enough to let me check the forest.  I have much less damage than my neighbors.
