Thanks for the comments Bill,
I do understand and appreciate the complexities of building old and
now the new software defined radios. I so wish I had been an
electrical engineer than a chemist/physicist turned software engineer
at times. I would maybe feel more satisfied professional and have
more fun building radios than payroll/web programs.
Some 30+ years software engineering work now including embedded work
and a long time electronics hobbyist. I do like my software defined
radios like the Ten Tec Jupiter, ICOM 756ProII and the ICOM 2720
under discussion.
My main point was that I should be freely allowed to acquire such
service "tools" for them as I can for old radios. I do deserve to
lose warranty rights if I "modify" the radio without manufacturer
supervision. That is quite acceptable to me. I want the choice to
have the relevant tools if i wish to pay a fair price for them, not
just be summarily blocked from obtaining them.
I do also want to be able to self-check/tune-up the new style radios
I buy like I did with the old ones and hence service tools are not
just for "service" but for keeping them "fit" and also learning about
the new design methodologies.
Also, several ham friends are having a heck of a time getting their
out of warranty radios (not ICOM btw) "tuned" back up to their
designed/new parameters after they have aged a bit and I do not wanto
to have the same grief that they now have, ... so I want to
premptively obtain the relevant ICOM service information/tools for my
radios prior to a need for them. I assume that the modern "software"
service tools, like most service manuals have in the past, will
provide proper tune-up and alignment instructions, etc. so i do
not "hurt" myself or my radio if using them.
Regards, and thanks again for your comments.
