> I use only linear supplies where possible.  I couldnt care less about efficiency.  Why?  Ever listen to the trash a cheap switcher puts out on HF?  Unless well designed and filtered, a switching supply will raise the noise floor several S units.  Yes there are decent ones but i would rather not worry about it.  Yes TT makes decent switchers, such as for the Orion, but ever hear one of those when the fan kicks in?  In my area a great deal of HF hash in generated by all the cheap Chinese supplies that dont adhere to our EMI standards, but we still accept their imports. No I will take my Astron 50 amp 12 vdc supply any day.  It runs my O2 and Harris RF-3200E quite easily while loafing along.   Jim N4BE
