Re: New Members - please post your introductions here

I go by SpaceToast. I'm a grumpy old dude, so I'll keep this short & sweet: I'm older than dirt & twice as ugly. A few decades ago I was an Electronics Tech in the US Coast Guard. Then some other stuff happened which brings us to now, when I'm a Ham radio operator and general tinkerer re-learning some of the electronics stuff I used to recite in my sleep.

See ya "in there".....

Re: Ham/CB/other transmitter radios... linear vs switching PSU?

I have an Icom 7100 in my shack that draws 23A *max* when I transmit 100W on the HF bands, and I power it with a TekPower 30A SMPS.

The extra current capacity means that even with the 7100 occasionally drawing 23A, I still have a little power in reserve for other gear. It has an adjustable output with a detent at the 13.8V position, and it lets me adjust the switching frequency to help reduce EMI in the form of harmonics produced by the switcing process.

Of course, changing the switching...
