Robert, My vote is for the Motorola TPN1106. Besides having the appropriate regulators and cable harness, it is capable of operating continuously at full load, which the Astron RM-50 cannot do. The Motorola is marginally more efficient, 63% versus 59%. What is important is that the TPN1106 with the C29 Battery Protection and Alarm Kit includes on-air alarm tone and low-voltage disconnect, which the Astron lacks. I believe that the Micor TPN1106 represents the high-water mark in heavy-duty station power supply design, while the Astron is designed to meet a profit target and is a lightweight contender by comparison. Opinions vary...

What say the group; Micor TPN-1106 (w/battery backup) or Astron RM-50M (w/battery backup) Add on some sort of 9.6v reg. board for the Astron. Don't have a TPN-1106 yet but will be looking for one if I do go that route. PA is 100watt cont. Have a TPN-1100B right now. If there is a add on board for that (and have been told there is not)...might look at that. Will be making a quick run to the Stone Mtn Hamfest in ATL on Nov 1st if someone has one for sell. Thanks, Robert KD4YDC
