[Elecraft] K3 Sub-receiver use

Hi Rudolph,

I am someone who also works 20m JT65A on 14076 and 6 meters, mostly FSK441 
meteor scatter and of course SSB/CW sporadic-E when it's happening -- and if 
I had a KRX3 second receiver, that's exactly how I would use mine. As far as 
I know, that configuration is quite possible. I do also have a DCI 8-pole 6m 
bandpass filter inline with my PR6 preamp, which would be protected thereby 
from the HF transmit signal field. I don't know if the filter is strictly 
necessary while using the K3 to transmit at basically QRP levels of <75W. 
But with the DCI filter, it should be no problem for the 6m receive chain.

I'm not going to be in a position any time soon to get the KRX3, but when I 
do, that's how I will be using it mostly. I'm looking forward to hearing 
confirmation from others that this configuration will work.

PS -- Will be looking for you on 14076 JT65A -- need your country on that 
mode/band.
