To standardize my little vertical based antenna farm, I am wanting to buy an ACB-10 for 10m, but they are no longer available and I cannot find any other make/model of a 4-square system for 10m anywhere on planet Earth, so is it possible to buy a 20m Comtek relay unit and put it on 10m?

If so, what all is involved?

Anyone have any working knowledge of the outside relay boxes? I presume it must be something to do with the toroids, but I've never had one apart, nor do I even have a schematic for the outdoor unit.

Thanks !

CU (all of a sudden!) in the next one.

p.s.-my backup plan is just to build another K1WA/K8UR/K3LR/N6LF vertical dipole array.
