Topband: DX Conditions

[GEORGE WALLNER]

On RBN Sensitivity/Antennas:
Whenever I CQ-d from any of our Pacific operations -- FO/M, FO, VP6A, E51D, 
KH8, KH8S -- I always had the RBN screen on. Most of the time I would be 
working stations in the mid-west, or even the East Coast,  before the first 
RBN report would pop up, if at all. As Steve points out, they do not have 
high performance RX antennas for 160 m and you can not rely on them to 
indicate weak openings. Of course, if you see your call on the RBN, the band 
is solidly open.

73,
George

ZF9CW is a good, sensitive setup down in the Carib that I do look for, however. One of the more-sensitive out west may be W6YX, another VE6WX, both with at least two reporting receivers. There are several others at large contest stations such as ND7K who seem to report much less frequently. There are even several KH6 stations on the RBN. BUT...

>You have to rember that MOST "serious" 160 ops are using low-noise antlers such as Bevs or Flags, when they give out those 559 or 579 reports to you Euros. The RBN stations are invariably NOT using such sensitive (and directive) antlers; so of course, they're only going to hear what their low elevation, RBN-receiver antlers are hearing, amongst their local noise. Thus, it's rare that I see a west coast station report even a JA, let alone 9M2AX or similar, never mind in-the-noise European. Rember: the signal must be a dB or more out of the noise, long enough to copy a complete callsign at least several times, before it will even consider reporting you.
