Two Receivers

Bill Levy
First I want to applaud all those guys that are better operators than us
using just one receiver.

However when I started there were seperate TX and RX and then there was a
Transceiver and I kept my Receiver.  Interesting thing that 2nd RX. You put
the DX on the RX and you find the guy talking to him with the transceiver
and that is called a SLAM DUNK.  When the Panadaptor came along we didn't
have tune around looking for who DX was working we could SEE IT.

I guess you can do the same darn thing reversing and A/Bing and using RIT
or TIT or all this nonsense that is totally unnecessary if you have a 2nd
RX.

I guess what I am driving at here is there are many ways to skin the cat
but the easiest way is with a 2nd RX and Panadaptor (pictures being worth
10 thousand words)

But I do seriously give credit to those who prefer doing it the harder way.
When I was rock bound in the good old days we had to tune up and down the
band to find who ever may or may not be calling us. Long CQ's and longer
replys to get the qso started. It's so much easier than that now. Same
amount of fun still.

I probably shouldn't give away secrets but if you try this on some big
DXpeditions, you will be sorely disappointed.

For example when I was calling VP8STI on RTTY (my friend AA7A operating) I tried
calling on his last listen frequency but he never seemed to call two stations
who were on the same frequency.  So I started looking for a pattern; many guys
will tune up (or down) a few Hz or kHz and pick another caller.  This didn't
seem to be the case either.  After nearly two hours I finally determined his
pattern was.... he didn't have one, he randomly tuned after every Q.  I finally
picked a relatively clear frequency and called for awhile until he found me.  I
queried him about this later and he confirmed.

In either of these cases you really don't need a second RX to figure this out. 
Your time is better spent learning sequences and planning when and where to call
instead of constantly tuning trying to find the last guy worked. Besides all of
the other two-receiver guys who don't know any better are going to be calling on
the same frequency too.

But how can you figure out the pattern (or lack thereof) if you can’t find the stations he worked?

You guys need to read the book “Complete DXer”. It was written by a CW operator but what he talks about works for SSB too.

In reply to this post by Vic Rosenthal
I could have ten receivers and if all the callers are in my skip zone I wouldn't
hear them either.

One other thing that I didn't mention, but should be obvious, although many
callers ignore it, LISTEN to instructions. (Unfortunately too many expeditions
these days fail to give them---or their callsigns---often enough, assuming I
suppose that everyone is using spotting networks to figure this out.)

Listening example:  I don't remember the expedition location but do remember one
of the participants was the banquet speaker at Visalia in 2002, where he
coincidentally mentioned this very thing.  He was working a pileup on 20-meter
SSB on 14.195 and announced "Listening up 5 to 10..... and 14.190".  I called on
14.190 on worked him on the first call while the other thousand guys battled up
5 to 10.
