Paul - I cant speak to the switchers that you mentioned above but the IOTA's are very well designed and some of the fellas I know that have used them & the older Todd switching supplies to power there HF equipment have never had a problem with them causing birdies. Heck, alot of HF gear now a days has switching supplies some of which are built in as an option. Many repeaters that I am aware of have switching supplies powering them. This is not as uncommon as you make it sound......dan n2aym
