[ICOM] R-71A

[sdaitch at KUW.IBB.GOV]

After looking over an Icom R-71A and finding poor sensitivity,
I think I've discovered DS1 between the SO-239 antenna input and
the RF unit input at EP2 is open.

It looks like Icom uses a mini-lamp of some kind as an overpower 
protection unit for the RF input.  Bypassing the DS1 and the 
sensitivity appears about normal.

None of the on-line information that I could see has the parts
breakdown for this unit.  I suppose any really small lamp bulb
would work, but for purity sake, what is the trade number or
specs for the DS1 bulb?

thanks,
