Differenced Between Filter "KFL3A-2.8_2.7sw" and "KFL3A-2.8K"?

[Jeffrey Maass]

I was planning to take a block of hours tomorrow to add the KRX3 to my K3/100.

One of the things to do is to replace the 2.7-KHz filter with the 8-pole 2.8-KHz filter in
the main receiver. I have one "KFL3A-2.8K" that I ordered a while ago for this purpose.

Now I see from the Elecraft order page that there is the note:

   "Order KFL3A-2.8_2.7sw instead if replacing
   2.7 kHz stock filter."
 
Does anyone know what the different is between "KFL3A-2.8K" and "KFL3A-2.8_2.7sw"? Should
I wait to get a "KFL3A-2.8_2.7sw" to swap out the old filter in the main receiver?

Hi Jeff,

>From the order page:

"KFL3A-2.8_2.7sw   2.8 kHz 8-pole REPLACEMENT of the standard 2.7
kHz 5 pole filter

"(For the K3 and /or the KRX3 - Only at time of initial shipment
of the K3 or KRX3. Please state if the replacement 2.8 kHz filter
applies to the K3, KRX3 or both in the order comments section. Two
of this item must be ordered if for K3 and KRX3.)"

In other words, if you order a K3 or KRX3 (which come with the 2.7
kHz filter by default) and you want them to replace the standard
2.7 kHz filter in your order with the 2.8 kHz filter, the lower
price ($95.95) can be had if you indicate this in your original
order. If you order the 2.8 kHz filter separately, as you
apparently did, the price is $125.95.

There is no technical difference between the filters, just the
price. So you can safely replace the 2.7 kHz filter with the 2.8
kHz filter that you have.

There is a 2.7 kHz filter and a 2.8 kHz filter.  

The KFL3A-2.8_2.7sw is an order entry item for people that wish to order a
K3 with (just) the 2.8 kHz filter instead of the 2.7 kHz filter that
normally comes with a K3.

It's a "swap" order item.  If you order a K3, and then order a separate 2.8
kHz filter, you'd pay $125.95 for the 2.8 kHz filter and you'd have an extra
2.7 kHz left over.

If instead you order the KFL3A-2.8_2.7sw at the time you order your K3,
it'll come with just the 2.8 kHz filter, and the 2.8 kHz filter "upgrade"
costs $95.95. They won't send the "stock" 2.7 kHz filter.

But you have to arrange this "swap" before your K3 or KRX3 is shipped.  

Dick, K6KR
