[1000mp] Pin diode mod.

[GRAEME JACKSON]

Hi Dale, tnx's for the reply, took so long to reply cos i was hoping more
people on the relector wud come in with info.
I have used the advice you gave but to no avail,
Cant seem to find any usefull info on the web about the MI204......spent
hours looking !!!!!!!
Maybe i'm looking in the wrong place....hi hi.
A frind of mine has found a couple of ham radio mag articals on IMD etc
using pin diode switching.........hoping to see him this weekend.  This may
shed more light on the subject for me.
Anyway once again tnx reply

Best wishes for now .....Graeme.

MI204 is a Matsushita PIN diode.  Do a google search.  It should be ok.
