There was a time when one could email Elecraft support with the K3 serial number and they would send the factory Config file. Probably not 100% of the solution but it would be a start. 73, Brian, K0DTJ > On Oct 17, 2023, at 09:05, W3FPR wrote: > > Jim, > > It is doubtful that will work

Re: [Elecraft] K3 Filters

Jim, It is doubtful that will work if the K3 has been set to factory defaults by EEINIT. 73, Don W3FPR On 10/17/2023 11:59 AM, Jim McCook wrote: Dave, Open the K3 Utility and click on Calibration.  Scroll down to Configure Crystal Filters.  The top line shows the various bandwidths of

Re: [Elecraft] K3 Filters

Dave, Remove the top cover - there should be a sticker either on the bottom of the top cover or on the top of the sub-RX showing the filters installed and the offsets if they are not the 8 pole filters. If the sticker is not present (or is incorrect), then yes, you will have to remove the

Re: [Elecraft] K3 Filters

Hi Dave, Without a saved CONFIG file, I don't think there is a way to retrieve the filter settings directly from the K3. Have you tried examining the filter settings for any information that is stored in a CONFIG file? The K3 Utility permits viewing and editing stored crystal filter settings.

Re: [Elecraft] K3 Powers Off On Its Own

On one of my K3's the Powerpole receptacle got flaky. Turn the radio on, and then wiggle the plug  to see if it drops out.  I resoldered where the receptacle pins mate with the circuit board inside, but I still had to use a tie-wrap to hold the plug in a certain position.  I'll fix it the

Re: [Elecraft] K3 subreceiver works on CW only

Hi Erik, Did you check the filter selection for the sub-receiver to be sure you don't have a blank slot selected for SSB? 73, Mike, K8CN __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help:

Erik,    This sounds like the filter setup for the sub receiver is not correct. Gordon - N1MGO On 8/25/2023 2:38 PM, Erik Wheeler wrote: Hi all, On my K3 (serial 1773) my sub-receiver only works on CW. On SSB, I just hear faint white noise. Is this just a setting problem? I've been through

Re: [Elecraft] K3 Power-hunting on FT8

Hi Dave, Joe, and Jim The GMSK to AM distortion across any 50 Hz bandwidth of a K3 filter would seem to be minor. With an FT8 symbol rate of 6.25 symbols per second, would that not create some relatively weak 6.25 Hz sidebands plus a bit of mush around those lines due to the pseudorandom

Re: [Elecraft] K3 channel hopping anomaly

Hi Fred ... I don't think the "channel hopping" procedure described on page 40 will accomplish what you are wanting to do because it says (in bold type), "Memories to be used for channel hopping must be within the same band ..." Furthermore, tapping M»V twice always puts the Memory content

Re: [Elecraft] K3 Power-hunting on FT8

Doppler caused "spreading" is readily identified ... the spreading is generally in one direction (because airport "patterns" run in one direction) and often manifests as a second signal offset by 60-80 Hz (which can be independently decoded). IMD is generally in both directions and can not be

Re: [Elecraft] K3 Power-hunting on FT8

Hello Mike, Thanks for sharing your data!! Help me understand something you said... Are you saying that at 2 bars, (for your K4), all spurious signals, are at least 80 dB down from carrier, while at 5 bars, all spurious signals are running around 50 or 60 dB down from carrier? 73, and

Re: [Elecraft] K3 Power-hunting on FT8

That the K3 and K4 are clean transmitters (for a 12V final) is awesome for everyone on the air. Elecraft sets the bar again. But the highly popular JT modes are not the only audio based digital modes used these days. Others are more complex than one continuous phase shifted tone. With that

Re: [Elecraft] K3 Power-hunting on FT8

I have been running tests on K3s and K4s to understand the conditions needed to transmit clean FT8 signals. I have previously shared some of my findings with Pete N4ZR and a couple of other folks. Their feedback has been very valuable. Joe Taylor, K1JT has shown the spectral purity of the FT4
