Measuring was made by my friend Vladimir three years ago and he haven't original generator at disposal now. But he have now new analog generator ( with analog rejection filter ) and new sound card, which have even better results ( but similar to original measuring method ). Generator + rejection filter :
The coil winder is not well but if he won't be back next week I must use plan B. It's a short week in Sweden this week. Thursday is a red day and friday is a "klämdag", most people make themselves free. I'll really hope that I he wind the coils the following week. The letters are ready to post so it will be no delay from my side.

Great looking boards. 🙂 Glad I ordered. I'll have at least one done as soon as my work schedule allows. Hopefully sooner then later.

The rest is now posted except for ex700. Your address. Send me a message. My DNS has been down for quite a while but seems to be up again. If you can't get my homepage, the DNS is involved and I can't get my email either but it works at the moment.
I searched for ex700 not ex007. BTW I have still internet troubles. Can't reach my domain and also my email.
