Hi,

 

it seems that Hermes provides a much better RF isolation (decoupling,
shielding, grounding of ANT plug and path to relay) than the MERCURY
layouts. Riho's hint concerning the usage of a choke is very helpful -
thanks  -, but depends on the individual wiring.

In my case I have only two significant   spurs on 28.224 and 28.416 Mc. All
other are in the noise floor,  using a 2 el cubical quad in my suburban
area.
