to Ijaz Ahmed :
All that I knew, is :
APR 9300 or APR 9600, such suspect I have,
is a light copy of ISD devices series.-
Somebody toll me, "what a noisy are",but
no trace of manufacturer brand .-
May be Hindu, perhaps .-
Time ago I saw one desing kit, DIY type,
they call it A Plus or something like this.-
Just I don´t remember right now .-
Thank you in advance for your time .-
