[Elecraft] new KPA1500 Manual

[Peter Hall]

Bill,

Having spent time, over many years, piecemeal updating Jeppersen and CASA (the national aviation regulatory authority) pilot documents,  I regard it as wasted time I'll never get back.  I hope that Elecraft does not go down this path but agree absolutely that, these days, good searchable PDFs make life much easier. One thing that is always useful is the update register (already often used) and text markers indicating changes from the previous edition (often vertical bars at affected paragraphs).   

On the subject of the KPA1500 manual, I have much appreciated the additions to the original document but would like to see the block diagram expanded to make it more useful in terms of appreciating the amplifier topology and the relation to connectors, etc.  For example, the current very terse diagram does not show the pre-distortion coupler or its location and, if you hadn't had a spectrum analyser on the amplifier, you might not appreciate that it's not a direct output coupler.  Of course, I'd like to see the whole schematic but I understand that it must be a tricky commercial IP balancing act with a new product.

73, Peter (VK6HP).

Right on!  First, I have over two decades of experience with replacing printed pages in Air Force Technical Orders.  What a PITA, but necessary. 
Today, those are distributed electronically and printed locally.  Often, it's not possible to make a change that affects only one page since the change, often an addition, pushes  information on to the next page.

Thanks to Elecraft (not all manufactures do this), we can annotate the PDF versions with the latest firmware notes, ideas from this reflector, our just our own pointers.  The PDF then becomes a current, searchable document of great value!

As I point out in my ham radio presentations, it's 2019.  We do a lot of things with computers now.  Join the 21st century.  The technology has certain advantages, especially if you back-up your data.

73, Bill, K8TE
