Need some help on getting the Titan to key up using the Icom 756! My Icom hr has only one outgoing keying line, but the Titan requires two lines! Why seems a bit silly for that! Yes I know the PTT/VOX plug needs to used, but it still doesnt key the amp! And my manual here doesnt seem to cover it very well! Any tips would be greatly appreciated! thanks, Steve/WD5HNI
