[R-390] PIN Diodes and counter

[Perry Sandeen]

GM List,

I want to make a loop antenna and be able to change the amount of turns electronically by using PIN diodes to short turns.  The problem is that 1N5719 and the HP series cost around $5 each.  They make PIN diodes for 40 some cents each BUT they are new SMA(?) size that makes them about 1MM long.  

This far to small for my abilities.  Does anyone have a cheap(er) source for PIN diodes with conventional leads or some leadless ones that are larger?

I'm also looking for a HP 5370B TIC

Also for those on a budget there are very good values on Tek scopes on Epay.  Many have DVM functions on the screen.  With the scope and one of the newer inexpensive DVM’s a great deal of repair problems can be solved.

Regards,

Perrier
