        Joe:

        According to my in-house infectious control 
        expert who wrote the famous study "RF Pathogens -
        the CQ CQ CQ VIRUS and it's impact on 160
        Meters", the virus cannot be prevented as it
        is the direct exchange of RF emissions that
        causes the viral infection.  It cannot be
        prevented by the mere use of tower condoms, 
        stubby or otherwise.

        The only known and accepted method of prevention 
        of the CQ CQ CQ Virus is the practice of chasity
        and abstinence - which is to say, don't CQ..

        Just thought you'd like to know....

Dear Lisa,

You have probably heard some fallout from the following comments:

What you may not of received are some comments pointing out the technical
error of this quote.  Simply put, static isn't caused by other transmitters.

Static results from insufficient signal strength at the receiver.  This is
typically caused by having the receiver too far from the transmitter, having
the antennas improperly orientated, or by objects near the antennas causing 
reflections that cancel out the desired signal.

Most transmitters I know of do not transmit static.  Amateurs either 
transmit morse code signals (very easy to tell from static) or voice 
signals which again are easy to tell from static.

Our family has used cordless phones for five years now, and have never had
any problems with interference from my transmitted signals.  This actually
surprised me, as I run the maximum power level allowed by my FCC license of
1500 watts.  This is probably over 1500 times the power level of the 
cordless transmitter.  

We recently replaced our old phone with a new one (with ten channels) and 
we have had to change frequencies 3 times in the two weeks we have had it.
The interference was being caused by other cordless phones in our area.  
Again, this surprised me, as I live in the country and have less than
100 neighbors within a mile of me.

It is obvious to me that true interference is much more likely to be caused
by another cordless phone than an licensed Amateur Radio operator, a 
unlicensed Citizen Band operator or even the very rare unlicensed station
not falling into these two categories.

I encourage you to improve the technical accuracy of your comments.  This 
will not only give the consumer better information so they have a better
chance of actually solving their problem, but it will eliminate unnecessary
conflicts between Amateur Radio operators and cordless phone users.

The FCC is a good source of useful information on interference situations.
They have a booklet they send to people who do complain about interference
problems.  Perhaps this would be a useful document for your editors to 
become familar with.

I hope you can find some way to undo the damaged reputation to Amateur
Radio these incorrect comments have generated.
