I have a copper clad which has a copper very thick: at least
300um (standard clads have 32 or 16 um). It may be even 500um
(0,5mm) I just do not remember well. Sorry for the metric values :)
Anyway - it is more than 10 times thinner than usual.
I am thinking about ugly metod of building (using stand offs)
for a direct convertion receiver - should I expect the problems
with ground loops?
I would like to build this way the Roy Lewallen Optimised QRP trx...
If I am not wrong - ground loops cause hum, right?
