[TowerTalk] ChatGPT

[David Gilbert]

ChatGPT is often a quicker way to get an answer to a question than for 
example, doing a search on Google.  But that's because ChatGPT can 
simply pull stuff out of its database for the answer and come up with a 
reasonable aggregate response.  A question on history, or asking for 
what something means, or a description of something is a great use of it.

ChatGPT is far less reliable for solving problems, although it often 
gives surprisingly close answers.  If you simply take a ChatGPT reply to 
a problem at face value you will often be misled.

I have on a few occasions asked it to write a simple bit of software 
code and the responses I got were clearly wrong each time ... typically 
not be very much but still wrong.  However, if you know that the 
response is wrong you can tell it so and it will come back with a better 
answer.  My son and a friend once asked it to write a more complex 
section of code and it finally got it right after three attempts, but at 
this stage of ChatGPT's development if you probably need to be smarter 
on the subject than it is.

I once asked it a simple circuit design question and it got it wrong.  I 
would never base an antenna design or tower design on ChatGPT.

I don't have access to the latest paid version, so I'm only talking 
about the one that is freely available.

It is also possible to massively confuse ChatGPT.  I have asked it on 
three different occasions "how many dimes are there in a nickel" and 
gotten three different responses ... the weirdest being a full paragraph 
explaining why the answer was "ten".

I am totally NOT trying to demean ChatGPT or AI in general.  This stuff 
is amazing already and I use it quite often.  It is quickly going to get 
a LOT better and before long I have no doubt it will do what you want, 
but at this point it is far from being infallible.

p.s.   I just asked it for the dimensions of a 2 element Yagi antenna 
for 7.050 megahertz and got this response:

The dimensions of a 2-element Yagi antenna for a specific frequency 
depend on several factors, including the desired gain, impedance, and 
beamwidth. However, I can provide you with some approximate dimensions 
for a 2-element Yagi antenna designed for 7.050 MHz (40 meters) using 
the following specifications:

  * Boom Length: 11.8 feet (3.6 meters)
  * Element Diameter: 0.5 inch (1.27 cm)
  * Element Spacing: 0.2 wavelength (approx. 9.5 feet or 2.9 meters)
  * Reflector Length: 20.3 feet (6.2 meters)
  * Driven Element Length: 19.3 feet (5.9 meters)
  * Gain: 6 dBi
