For at least three or four months the KangaUS website has stated that the W7ZOI SA "Kit" is the next to be reinstated. I recently sent an email to Bill Kelsey asking about this but to date no reply.
Does anybody know what the situation is? I wish to build a simple SA and the W7ZOI design would be ideal.
I fully understand and appreciate the KangaUS problem, it must be devastating to lose everything as they did.
Any information will be appreciated.

Hi Norman, et al,

Bill is working on some new PC Boards for the SA. He is doing the layouts himself, and then plans on building the analyzer to confirm the results. I'm not sure, but the original artwork may have been destroyed with many of the parts that also floated away in the flood.

My partner in that project, K7TAU, is no longer doing electronics. So he is not supporting any of the SA update efforts.

I think that Bill will eventually get new boards and will again have a kit available. However, if it were me, I would elect to build an ugly versi

Hi Norman -

I see Wes has already responded to your note - and he pretty much covered things. I am in the process (slowly) of updating the PC boards, and then will build a unit to be sure they all work together. I was gone for the summer, and now that I am back I have started teaching a class at the local community college that is taking a good deal of time. The SA will be the next kit I bring back to life - hopefully later this fall - but I can't make any promises as to when it will happen.

I apologize for not responding to your e-mail - I don't see it in any of my folders. It may be

Did you check to see if the PCB shop that did the original boards has the
Gerbers on file? Some keep them on file in case you want more boards made.

Hi Norman. I see that Wes has already replied to your email....I have built his SA both with the boards and again with ugly construction that I later modified somewhat.  Yes I have two of his SA's. Both work beautifully. As Wes mentioned, if you can get the parts, consider going for the ugly construction if you want to move forward with the project in the near future and then you can enjoy the fruits of your efforts....John K5IRK

I got the bug to build Wes's SA just after Kanga had their flood and proceeded to carve out my own boards on a small milling machine. The process was a bit time consuming but well worth it. If I were to do it again I'd use SMD construction for most of it and use the ground plane side of the boards as covers for the cast housing--should make for great shielding and a really nice SA. Good luck with it and I'm sure you'll enjoy the process.

Hi Wes and Bill,
Thanks for your explanation.
You hit the nail right on the head Wes.Trying to procure any out of the ordinary components etc is a nightmare. I've found that the "Kit" where everything is provided is cheaper in the long run even though many of the common parts are already in my Junk Box..
One order, one payment, one delivery.
I'll have to think about it! Waiting another couple of months wouldn't be that disastrous.
