The links to sound files contained in the PDF file should still work - but as the links are directed to storage on my website you will have to be connected to the internet to hear them.
NOTE: External links (to other websites) are still included in the PDF file - but are likely to be out-of-date.
See below for a summary of the things that are contained in the above PDF file.
Please Note - Due to the large number of emails I receive asking questions about the topics presented here I must regretfully decline any requests for further information. The information presented here has been developed over many years and I simply don't have enough time to "keep up to speed" on them. Currently I am not active in any of these interests so the topics here are historical and for informational purposes only. Please do not send questions as a non-response may offend.
Thanks - Steve Olney - VK2ZTO (now VK2SRO).
NOTE: I have received a number of requests (to which I have agreed) to either link or quote a summary of my experience of the internet that existed on my old VK2ZTO site.
To address those past requests and future requests I have separated out that text into its own PDF file which can be found here...
You are free to use this as long as I receive an acknowledgement.
