Re: Topband: Changing received signal levels

 I gotta think that Top Band offers some unusual operating
 conditions that, amongst other witness states, shows us
 clearly how dynamic the band is!

James, 
  That is very common from here, Sometimes during the whole contest I have 
a few seconds to work stations. I have to break just prior to the peak, 
exchange during the peak, and then the station begin disappearing during the 
confirmation. 

Many times If we fail to hear well during the exchange I have no second chance 
and have to wait up to 5 to 10 minutes for the next QSB peak. 

If time and conditions permit, I will be participating during the SSB version 
at the end of February.

Lets see how many of you conditions will allow me to work with Eddy, LU2DKT

Topband: Changing received signal levels

2013-01-27 Thread James Rodenkirch
I saw an exchange here, earlier, where someone was mentioning calling a station 
with a weak signal, only having them come back with a stronger signal.

I witnessed that more than just a couple of times during the recent CQ WW 160 
contest and attributed it to, mainly, very dynamic conditions.  I heard strong 
stations, who were calling CQ while tuning across their frequency that, when I 
tuned back, to be certain I'd copied their call correctly, I found their signal 
strength to have changed - up or down, in some instances, as much as 2 S units! 
 That's some serious quick changing conditions!

I believe several that I called and called and CALLED (I was a QRP entry) 
finally heard me 'cuz they had switched beverages or rotated their pennant/ewe 
antennas...so, I attribute much of that to band changing rapidly and or 
altering transmitting antennas!

I heard HL5IVL this morning at one point where he was a solid S5 here in s/w 
Utah and that was just as he signed off with a W6...he sent his call moments 
later and his signal was just at the noise level.

I gotta think that Top Band offers some unusual operating conditions that, 
amongst other witness states, shows us clearly how dynamic the band is!

FWIW - I'm not a SUPER contest station like many are but...I sure do see lots 
of evidence of the above with my puny antenna system - hi Hi
