[Elecraft] Custom 700 Hz 8-Pole INRAD Filters--You Should Get in Queue!

[David and Dianne on Comcast]

Hi Everyone,

I recently purchased and installed the 700 Hz 
Custom INRAD filter from Gary-KI4GGX of 
www.unpcbs.com.  In the nearly two weeks that I 
have had this filter installed in my K3, it has 
become my primary CW filter for this rig.

I am not a contester but rather a search and 
pounce DXer for many years now (35+).  My first 
rig as a novice was a Heath HW-8 in 1977. It was a 
QRP CW rig running 2-3w CW with an audio filter at 
750Kz. I worked 38 countries with a dipole with 
that rig. It taught me to learn to listen for CW 
DX using a broad filter bandwidth compared to most 
of the standard bandwidths used these days.

I have been using an INRAD 8 pole 500 Hz CW filter 
in my K3 since I got it in 2008. But I had been 
thinking about Gary's 700 Hz filter for a while 
now and I finally decided to take the plunge two 
weeks ago.

For me this had turned out to be the perfect CW 
filter. I find myself using it exclusively now in 
all but the very most difficult situations.  
(Remember I do not contest.) It allows me to 
cruise the CW bands from a wider perspective 
helping me to gain a more macro-orientation to 
what's on the CW bands and making me use my brain 
more to differentiate between the CW signals I 
hear. It's a very comfortable filter to listen to.

For me this filter is a keeper here for sure.

As for Gary and unpcbs, both remind me of an 
extension of Elecraft. Excellent quality product 
with superior service on top of that.

If you are thinking of pre-ordering with Gary for 
an upcoming INRAD Customer 700 Hz filter batch, I 
can highly recommend that you do so.

I really like this filter.
