Agreeing with Bill and Ron.
Per the MDS Web Site:
"
The <http://www.mds-ham.com/RC-1-H-Digital-Rotor-Control.htm>RC1-H is
the ham M, II, III, IV, and Tailtwister control box. It is a UPGRADE
box, in that you must still use the power (24VAC @5A) from your old
control box, or supply your own AC power supply.
"
I saw the units at Orlando's HamCationsm.
Quite impressive. If I hadn't recently spent about $1K for a
Prosistel PST 2051 with a digital box I might have bought one for my
Ham IV. I still might buy one for my HamII on my UHF+ tower.
