The K2 sure is a nice sounding radio

[Elecraft mailing list]

A few months ago I was itching for a big kit build so I picked up a K2 (I needed a winter project)
I took my time building it and adding in as many options as I could fit along with some mods.

I'm sitting here listening to it and I was thinking it sure is a nice sounding radio; while it may

not sound as full as the K3 (the K3 has wider filters) but the K2's audio is nice and clear.

I only operate CW, but I've always thought the K2 was a very pleasant radio to listen to. I have one with DSP and one with the AF filter and I prefer the sound of the AF filter too. I've tried a couple of separate speakers, but still prefer the internal speaker for some reason. There aren't a lot of radios that have aged as well as the K2. It's the definition of "classic".  But then, what do I know? I still think my Drake 2B is a pleasure to listen to.

I built a k2 years ago and sold it off as I was moving to help with the care of my elderly father.
I had forgotten how nice the K2 sounds

The key to a "good sounding K2" is proper alignment of the IF filters.
While the filter settings mentioned in the manual will produce workable
filters, the best filter alignment can be done using Spectrogram (or
other audio Spectrum Analyzer) and a broadband noise generator.
That will optimize the filters for your particular K2.

You can download Spectrogram (either v5.17 or v16) from my website
www.w3fpr.com - look for the links near the bottom of the home page.
These are files local to my website and they have been scrubbed for
viruses many times. Both were declared freeware just before the author
stopped writing improvements and went out of business.  Norton may
object because it is not used frequently enough, but other anti-virus
applications give them a clean bill of health.  I understand that there
are some copies "in the wild" that do have a virus attached to them.

Instructions on how to set up and use v5.17 for the K2 filters (written
by Tom Hammond N0SS (SK) can be downloaded from the Elecraft website.
Google will find them for you.

73,
