Sandeep,

Thank You so much for the PCB update.
I know I must wait.

I hope others will understand, this is a project with opportunities to learn
and experiment.
One must work a small section of this radio until you understand it and make
it work before going to the next area.
Unlike Kits that are on the market today, the Minima was developed where
resources are limited and experimentation is a way of life.

I thank you and Farhan and others that have so kindly shared your skills
with the rest of us. 
We are excited about joining you in the thrill of building such a radio.

I will wait patiently for the PCBs to arrive and in the meantime read the
Minima E-mail and enjoy the discoveries!

M sorry, I didn't sent you any PCB...
I request you to please have some patience, plzz wait.
My current service was for initial stage of development only, as to support
R&D from hard-players...

Those having set of PCB in States:
(or might reach in next 1~2 days, on average max by 20 days, it takes no
more then 2 days for them to board on plane from my county, but might get
stuck in customs in your country for X-Ray & further clearance, I have
written as free gift on all)

Don Epand ( USA  )
Todd Gruener ( USA )
Charles Vest ( USA )
Harvey Hunter ( USA )
Jerry K5LRU ( home-etched )

But I equally don't want you disappointed Plzz see in attachment for MINIMA
Part list, Adrian designed.

& equally, I suggests who ever comes with commercial/final, it's CAD should
be visible for transparency.

Rest of your questions I left on some else to answer, or may be later :

>    4. Can all 4 relays be of the same type? I know nothing about relays;
