Default Re: Homebrew transmitter project (Frank vs. Oskar :) )

Hi everyone,

Progress report:

I have been CAD:ing the PSU box so that I can print a A3 sheet, apply it to the box and use directly as a drill chart. Basically finished. Just waiting fot the mod. transformer.

A quickie question:

Switching in the ATU (connecting different taps of the matching coil, moving cap to left, right side of coil). At my power level (25W approximately), can this be done with "regular" spec switches? Just wanted to know if I absolutely, definetly need RF-high-voltage-switches. It's hard to tell exactly what voltages will be present in the ATU. But say 200 volts maybe?

You can never have enough of them junk-boxes. Allways something missing . I'm looking around for some koax connectors too, they're not cheap! The electronics industry should give away hardware for free to experimenters!
