[Elecraft] Effective add-on for your K1 or K2

[Robert Parker]

Hi All;
I recently purchased a kit called the SCAF-1.  I built it in 4hrs and tried
it out with my K2 and K1 and am really impressed with the results.
The SCAF-1 is essentially a variable audio filter similar to the internal
audio board option in the K2 which I also have installed in my K2.
The Elecraft Audio option is truly a great thing to have and is very
effective.  The only drawback is that it's not adjustable.
The SCAF-1 is an outboard audio filter that has a pot for adjusting the BW
of the audio with at least 90dB skirts.  I use it with or without the
Elecraft audio option depending on the noise level.
The SCAF-1 virtually eliminates white noise and most hetrodynes as well as
narrows the BW of the signal to eliminate interfering stations in the same
passband.
Super on CW!
There was an older version of this called the Super SCAF and although very
effective, used BCD wheels making quick adjustment more of a chore.
The SCAF-1 is as easy as turning the pot to your desired BW.  It's extremely
sharp and IMHO complements not only the Elecraft Audio options but the top
cover is close in color to the K2.
My recommendation is to get the Elecraft audio filter option and build or
buy prebuilt the SCAF-1.
This is really an effective combination.  For a non-DSP filter, it's really
hard to beat.
I have no affiliation with this company other than being a happy customer
and just commenting on my experience.
