Hi Eric, Thanks for the info and sorry for not giving you the necessary information you request. Upon further digging into the issue, I've discovered that the Quantro low power module is not compatible with the Quantar back plane edge card connector. Edge card pin outs are quite a bit different than the pin outs from the Qunatar PA edge cards. So, that's the problem! Now I need a UHF range 2 100 watt PA assy. to get this up and working. Anybody have one for sale??? After I get one of those, then I can continue with trying to get it going.
