Relative example... A room full of Motorola Repeater Stations in non constant service costs about $30/month each to operate. Put the repeater into lock to talk mode (IRLP or Echolink) and the energy cost rises by almost a third (typical). One of the energy soaks is the well designed and constructed transformers within the repeater power supplies. Replacing the hungry Motorhead Power Supplies cuts at least 1/2 off the power bill, which is much nicer when you're the one having to pay it. > However, switching supplies are inherently noisy.

Many of the common 13.8 vdc switchers sold to the ham market will hose up at least the 160 meter ham band no problem, which is just above the am broadcast band I have on the shop when XM is stale. > If that 50 amp supply is fine, I see no advantage in the change. > Dave Cheers Dave, skipp
