Why not do the bias test in message 33816? https://groups.io/g/Elecraft-K3/message/33816 Wes N7WS

Thanks for the tip. I just ordered another CM500 from them. I have two already but they do fall apart and I've never found replacement covers, so I just buy another set. AFAIK I introduced these to th

Personally I used an SDR-IQ and SpectraVue software on my K3(S)s. But you don't have an SDR-IQ so you might look here: https://www.sdr-radio.com/external-radio I have not tried this and find SDR-Conso

Wait a minute Charlie. First you say a small amount/length difference can screw up a measurement and then offer a 1.5 to 2 difference in Z and the worst possible length to bolster your claim. I say ch

If it was a Kenwood you wouldn't need to be sending it in for repair. I have a K3 and a K3S. I've lost count on how many times they've been back to Elecraft; mostly the K3S. I use a TS890. Wes N7WS

Emilio, I do not know from personal experience but I recall reports that the phase noise of this device is not good. There is more to a good reference than frequency accuracy and stability but it is d

Save your money. The standard ref is as good as the "High Stability" one. Wes N7WS

You left out the biggest factor; disfunctional governments. We don't have a shortage of truck drivers, we have a shortage of drivers who own trucks allowed to drive in CA and who can afford $5/gal Die

The first K3 is 14 years old. The last K3S is ~ a year old. Wes N7WS

Why hasn't this been fixed? Wes N7WS

Drift in the BPF tuning. It's a long story but my K3S had to go back for replacement of trimmer caps. Wes N7WS

Yes, the SDR-IQ tracked perfectly. SpectraVue "knows" all of the frequency translations in the K3/K3S; it's totally seamless. You can do point-n-click and/or mouse wheel tuning of the K3. I never did,

Before moving to a Kenwood TS-890 I used a K3S, now relegated to spare status and before that a K3, now a spare to the spare. (I should sell this one) On both K3s I used an RF-Space SDR-IQ, using Spec

If the diode is bad the indicated SWR would be 1:1 at all levels. Wes N7WS

I know you think the BPF tuning is okay. I would tweak C128, C147 and C148 and see what happens. Just move them and put them back where they were. I've found flaky caps in my K3S, that "get well" when

If you want to get into RF power measurement in more detail here is a good reference: https://www.hpmemoryproject.org/an/pdf/an_64-1a.pdf There are later versions of this by the successor companies, b

It's funny (curious) that I referenced this three year old conversation just a couple of days ago. http://elecraft.365791.n2.nabble.com/K3-SWR-Numerical-Indication-td7643839.html If you muddle through

A couple of weeks ago I talked to VK3XXY from 03:58Z to 05:25Z on 20M SSB. Turns out we are both car guys and I own an Aussie-built (Holden) Pontiac G8 GT, so that was quite a conversation piece. Cond

Complete nonsense.
