Dave and all,
I hope that you can get the help needed from Doug and Dan. Certainly
the best and most knowledgable on the 505.
The only comment I have is with regard to the Smith Chart. The plot
will be basically useless unless a reference plane can be identified.
Seeing the plot is one thing, but where is it with respect to the
load / source.
Great going, you have really come a long way in a very short time.

Dave,
This (Windows)version is working better than ever.
Your two steps ahead of my thoughts on items that you incorporate.
Your pgm has a lot of advantages and ease of use over the original
505.exe pgm.
Thanks! I'm glad to receive good news on the latest revisions.
Looking fwd to the freq cal, if it's on the list of things to do,
hi.
There isn't much after that, or is there ?
Oh yes, many things on the agenda, time permitting. The first
thing I
want to be able to do is read all of the NRAM data and save it to
a
disk file for future uploading back to the transceiver. I think
there
is enough information in the programming specification file, but I
want
to verify the safeness of various commands. I'm hoping that either
Doug
Smith or Dan Kimball will assist me on that front. You know of
Doug,
QEX editor. Dan is listed as one of the Kachina technicians who
still
does repairs on the rigs. I sent him an email request (got a read
receipt) and am waiting for a reply.
Frequency cal is of course on the list. But the specification
sheet is
not very helpful or illuminating.
The data that the transceiver sends regarding the antenna impedance
could be very useful for antenna trimming. The retrieval and
display
(Smith chart or otherwise) should be included in the final product.
