Chuck,
In his response to your KRX3 vs LP-PAN question, Tom, W8JI, mentioned
the advantages of diversity reception by adding the KRX3 to your K3. I use
this feature very often of the lower 3 HF bands and strongly second this
recommendation . Using the KRX3 sub receiver in my K3 with a second receive
antenna, it's amazing to hear audio fading down and out in one ear while
fading up in the other ear with the result being perfect copy.
But another plus from installing the KRX3 sub receiver module is being able
to simultaneously monitor a second frequency. If you chase DX stations, you
know that many of them run split operation, listening to a known range of
frequencies. By monitoring your transmit frequency, if a loud competing
signal is heard on it, you can quickly and easily move the 'B' VFO to a
better TX frequency. Transmitting on a clearer frequency will often improve
chances of working the DX station.
If I had to make the exclusive choice between the KRX3 and LP-PAN I would
choose the sub receiver module. I believe it improves chances of working DX
over what the LP-PAN could do. That's not to say that the LP-PAN features
won't soon be added to my K3.

Hello guys.
I've been using my K3 about a month now and really enjoying it. Since I have
a keen interest in DXing and pulling out weak signals (DXing cw & ragchewing
cw) I'm starting to think about adding the KRX3 second receiver although I
understand that LP-PAN also provides second receiver capability.
I also understand that true K3 'diversity reception' greatly aids weak sig
copy and would only be available with the KRX3 receiver but not with LP-PAN.
Additionally, I use an older, slower desktop for playing radio and would
probably need to a better pc if i go the LP-PAN route, plus the soundcard,
and then the unit itself.
So if you had enough funds for either the KRX3 second receiver or the LPAN
which would you choose. I'm leaning toward the KRX3 but wanted to get the
experts' take on this as well.
Seems that the visual aspect of LP-PAN, while appealing, would be less
beneficial basd on my operating than the diversity reception.
Is that making sense?
thanks and 73.
