[Elecraft] K3 power output instability

2013-03-15 Thread Arliss
Here's follow-up on the power instability problem I have been experiencing with one of my K3s: Although I already had the latest firmware loaded in the K3, I reloaded the firmware. I also ran the VCO MD calibration and checked the 3 mounting screws on the bottom of the K3, as someone had sug

I've mentioned this before, but several seemingly inexplicable problems I have had with my K3 have been solved by simply doing a Parameter Initialization (see manual.) Just be sure to save your configuration first. May not help, but doesn't take long so always worth a try. One caveat, that Don W

Something similar happened with my KX3. Support told me to reset and reload all the firmware, and it worked fine after that. I recommend that you get advice from Elecraft. Their advice worked for me. wunder K6WRU On Mar 13, 2013, at 8:12 PM, Arliss wrote: > Running the low and high power TX ga

Hi Arliss, I recently had a similar problem with my K3. I contact Elecraft and received this response from Gary: - See if it will produce 12w on 160-10m, and at least 8w on 6m, in Tune, with the KPA3 menu set to Bypass. The VFO should be near the middle

Arliss, If you do not have the latest firmware loaded along with the latest K3 Utility, please load the latest and try again. If it continues to fail, contact k3supp...@elecraft.com. 73, Don W3FPR On 3/13/2013 11:12 PM, Arliss wrote: Running the low and high power TX gain calibration via th

Running the low and high power TX gain calibration via the K3 Utility gave the following result: "TX Gain calibration failed because power reading did not converge to a consistent value. 5W calibration failed." "TX Gain calibration failed because power reading did not converge to a consiste

Arliss, I would suggest that you run the Transmit Gain Calibration and see if that improves the situation. 73, Don W3FPR On 3/13/2013 9:10 PM, Arliss wrote: I'm experiencing a problem with instability in power output from my K3/100. No word back from Elecraft yet (it's only been a few days)

I'm experiencing a problem with instability in power output from my K3/100. No word back from Elecraft yet (it's only been a few days), so I thought I'd try here. The problem is that at relatively low power output levels (approximately 10 to 40 watts), the power output does not remain consta
