[Elecraft] Base Station

Bill,
     I am aware that the KX3 has dual watch. It's like having a second 
receiver but limited in frequency excursion. I also have a Tentec Orion 
II which does have a second receiver.

     Here's what I've sort of discovered. I came to find that I could 
zoom the spectrum to blow it up around the pile up. I could see who the 
DX station was working. I leave my receiver on the DX station, and use 
VFO B to move my transmit frequency to the station he is working. When 
he, the DX station, sends TU or QRZ, I drop my call in. Remember the DX 
station's receiver is still tuned to his last contact. If it turns out 
that I've walked into a really nasty pile up, like on a really rare one 
or DXpedition,  I find out how he is operating. He probably is working 
split and is going a bit up and then down, 1-5 KHz up from his 
transmitting frequency. I can find a hole in the pile up and wait. With 
a second receiver, you'll need to tune to find a hole and you may not be 
sure what is happening. I can see faster than I can tune. When I figured 
this out, I no longer used a second receiver or dual watch, and my 
success rate went up.

     My take on the need to have a second receiver is it's very useful 
contesting by the really good/high scoring operators; I am no where 
being in that group called good contesters. These operator hang out on a 
single frequency and call CQ; you hear these guys in all the big 
contests. They will tune around with their second receiver, OR, put the 
#2 receiver on another band to see if it's hot so that they can time a 
switch.  With my little antenna farm, it really isn't realistic to 
expect that I could hold a frequency, so running isn't going to be in my 
future. But I sure can search and pounce, and using a spectrum display 
does allow me to maximize my QSO rate and break pile ups.

73,
