I’ll point out something that I have learned over the past 20 years doing professional hearing research… The “Pain Frequencies” are those in the band from about 1-2 kHz. Too much of those and it becom

Hi, Just a quick note about a finding of mine from tonight. I had the rare chance to monitor the frequency behavior from cold start up of the K3, after having shut down a few hours earlier for some th

… I’d love to hear the answers from somebody who really knows… by my speculation is that they need to drop the power output on AM because it emits a steady carrier, while in SSB mode those peaks are m

Hi, I installed a pair of the new LO boards a few weeks ago, and today was playing around with watching the frequency stability of the K3. I didn't expect to see any changes as a result of the new LO,

Not sure what you think the competition is….? But I can tell you that it does a very respectable job on all bands, especially with diversity (dual RX) and sync-AM detection. My comparisons are the IC-

16 W is only down less than 1 dB. Is there any spec provided by Elecraft on what one should expect? Sounds to me like 1 dB variation is pretty normal and acceptable. That’s about 1/6 of an S-Unit. - D

That was an impressive demo video. So I ran my own tests last night on my newly updated K3 with the new synth modules installed, and also on my recently updated IC-7700. Where that demo video gave an

Interesting.... But that rating puts it high based on narrow spaced 3rd order IMD. T hat may be important in some situations. But it also ranks my lowly Flex-1500 higher that an IC-7700 or IC-7800. I

Yep... Happened to me, just like you. I blew the RX and had Electaft repair it for me. Now I'm much more cautious about stuff like that. 73 de Dave, N7AIG Dr. David McClain Refined Audiometrics Labora

The Palstar HF-Auto has a remote option. I use one here, but in the shack, feeding a 600 ohm ladder line to the antenna for a multi-band dipole. But I do understand that a remote operation is possible

Hi, The AutoNotch on the K3 is too effective! It’s learning rate is too rapid, and that causes it to lock on and off of rapidly varying voice peaks during SSB phone reception. The effect sounds much l
