[Icom] Frozen Send relay - 756

Mon, 27 May 2002 16:41:07 -0500

Apparently, ICOM "DID" realize the error, because my PRO II manual does 
in-fact show  .2 A. as the limit, would have been nice if they sent a 
service bulletin out on their web site stating that.
Oh well, all water under the bridge now.
