Hello All, Will a Yaesu G-450A rotator replace the azimuth rotator on a G-5500 az/el unit as a direct swap? The specs are "really close" on the G-450A but wondering if anybody has actually done this. I know the stand alone elevation G-550 rotator will replace the G-5500 elevation directly (I've done it). Thanks--- Mark L. Hammond [N8MH]
