Thinking about KXR3

[Jim AB3CV]

I'm considering asking Santa for a KXR3. I don't have extra antennas
but might someday so I'm planning to get matched 2.7Khz filters for
starters just in case diversity is in my future.

Since for now I plan on only using the KXR3 for split use in CW I
thought I'd just have the standard 2.7Khz in the sub and leave my
"serious" filters in the main where the DX or Fox is lurking. The sub
would be primarily for listening to the pileup.

In the remote chance I ever become proficient enough to be a Fox the
sub would be tuned to my transmit freq to listen for potential QRM
while the main would be trying to separate the hounds. Am I on the
right track?

Santa is getting stretched a bit thin so I thought this would keep the
cost within reason.

Think you have that pretty much sorted Jim. I have an 8 pole 250Hz roofing filter in my 2nd rx as I thought it would be good for 'mult-hunting' during contests but in reality hardly ever use it.

Not sure how important it would be to insist on a matched 2.7KHz filter either. Because the bandwidth is so high you can simply make the small 'centre frequency' adjustments in software without affecting performance hardly at all; obviously more of an issue for the narrower filters...that's my understanding anyway.

You'll really like having the 2nd receiver...have fun,
