It is a simple process to review firmware updates, and when appropriate, copy and paste an update into the PDF version of the manual in Acrobat Reader, and then save that file with the updates. Then, when one searches for a question, the annotated manual has both the then (manual's publishing

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

Andy, My suggestion is rather basic (I've learned that sometimes the most obvious is often missed, don't ask how I know).  Take the time to open the case and tighten every bolt, nut, screw and reseat the connectors (wiggle everything).  Then retest.  Over time, some radios self-loosen bolts

Andy You may have a solution in hand for the spurious… The stiffener plate mod kit is still showing as available. I am wondering if there would be any improvement gained by grounding the crystal cans in a K3 with the plate, or even necessary. K3STFNR_K3 Synthesizer Stiffener Plate Kit –

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

Thanks Wes, Mike and Ben, Ah - I hadn't realised the shield was there as a mechanical stiffener - I did think it was very thick. I did notice the microphonics while I was testing - of course a good solid thump to the radio is an important part of any debugging process to find dodgy connections

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

Correct.  My K3 was the first one to have the stiffener.  I discovered the microphonic synthesizer early on (2008 IIRC) and demonstrated it to an Elecraft engineer in my shack.  His radio had the same problem.  It didn't take high levels, noises in the shack would modulate it; they were more

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

Mike, That’s a good point. Is Andy referring to the stiffener or an additional shield around the crystals? Ben W4SC Sent from Mail for Windows 10 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help:

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

I believe the rather thick "shield" was actually a stiffener to prevent microphony at high audio levels using the internal speaker. Regards, Mike VP8NO On 01/01/2021 18:22, g4piq--- via Elecraft wrote: And a small correction to this in case anyone else gets inspired to do anything. Grounding

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

Andy, I would be interested as to what the shield looks like. I have a 73xx s/n that does not have the shield. At some point near the end of the their production, K3 was built with KSYN3A. How did you ‘ground’ the crystal cases? My radio came with the stiffener installed on the

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

And a small correction to this in case anyone else gets inspired to do anything. Grounding just one of the crystals improved the performance by about 8dB - but did not get as good as the KSYN3 with a shield. It clearly needs the full treatment. 73, Andy, G4PIQ From:

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

I think I have worked it out. Taking the lid off and poking about showed that if I touched the crystals at the DDS end of the filter on the synthesiser board, the spurious levels rose. Upon taking the lid off the other (newer) radio, I realised that the KSYN3 in the new radio (SN 8529) had a

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

Thanks Rick. To answer those questions. I'm measuring this with the radio into a power attenuator and then with additional attenuation into a Perseus SDR operating as a spectrum analyser - well below its overload threshold and with plenty good enough phase noise and dynamic range to see this.

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

I don't have an answer, I have no test gear that would even allow a look (other than another radio).  But I'm curious how you're measuring and observing (not doubting) these results. Except for the reports seen on the air to validate your observations; if the radio change barely affects the
