Re: K3 and CQWW @ W8JI's

[Ralph]

I had the pleasure of operating SOSB 80m @ W8JI's.  We had a complex matrix of phased Beverages hooked up to his K3 in diversity mode.  Typically I had one Beverage locked on EU and the other ear would scan other Beverages.  When the JA path opened up I had two separate Beverages listening NW.  The first time you hear this your jaw drops.  The noise floor was so low I could hear a pin drop.  JL1TS called in running 5 watts (yes on 80m with wall to wall signals) and I counted 112 JA stations worked during our first sunrise. 

 

I normally run a FT-1000MP MKV and I have used W8JI's MKV's at his QTH in the past.  What struck me immediately with the K3 was how quite it was with wall to wall LOUD stations.  There was no IMD or junk noise going on that is always present on the MKV (with INRAD roofing filter) during a contest.  I put the K3 in Passband mode (PB) and cranked about 450hz in on the filter.  Working up the band S&P was like using a laser.  I couldn't believe it.  I never recall a problem pulling out a DX station.  Like picking apples off a tree.  What a pleasure.   

 

Occasionally I experience something strange that I can't explain with the sub RX (right ear).  Sometimes right after xmit I could hear clear CW signals in the sub RX.  I though someone was jumping onto my QRG.  I used the RIT after each CQ.  As soon as I touched the RIT the signal cleared.  I told the first 3 ghosts to QSY before I realized it was a ghost signal.  It cleared as soon as I turned the RIT.  I was talking to myself which happens enough without my radio.  Sometimes when transmitting I could hear CW signals in the sub RX during the exchange. If anyone can offer an explanation I would be interested to hear it.  Tom thought it might have something to do with PB mode but that discussion was after the contest so I didn't get a chance to try it with the PB off.
