Cant find the downloads on quarter-wave.com.....

[jdclark]

Am I having a temporary mental lapse or what? I cant find the T-line mathcad sheet download anywhere on quarter-wave.com. The only think I can find requires a password and username..

So, whats up?

[dlneubec]

I believe they are no longer available.

Contact M.J.K. He was selling one year term licenses, annual subscriptions.

Well thats not really the DIY spirit... but I did send him an e-mail earlier.

As far as I know Martin has stopped downloading his sheets because of the abuse that was going on. I do not think he is offering the annual subscriptions any more.

It was done because many commercial outfits began using his work, rather than deriving the theory themselves, and profiting from his unique model which is closer to reality than virtually any before it. Before MJK's Mathcad sheets, fine-tuning of TL designs used to be fairly empirical, involving lots of trial-and-error. So it's unfortunate that this had to happen, but I think the same factor is partly to blame for why SoundEasy and LSPCad cost so darn much.

About 2 years ago Martin switched from providing completely free worksheets to requiring annual subscriptions for them at a modest price of $25 for DIYers, and a password/User name was required. Commercial users had to pay $250 annually to have access. Even with these changes, Martin still was being abused by commercial users and, also, did not get enough support from DIYers to justify his time in updating and maintaining the worksheets, so he's decided to stop providing his worksheets in total. Those having existing subscriptions will continue to have access until their current subscriptions expire. Those not having existing subscriptions no longer have any access.

I've been sending a few e-mails back and forth with him, this is pretty much what he said. He seems most upset about the support from the DIY community. Although I did tell him I think its a lack of support for TL and folded horn designs in general rather than specific to his work.
