I hope this board is open to equipment other than radios.? For instance, EF Johnson's line of antenna couplers such as the 250 W or I KW "Match Boxes"? Other than not tuning some of the newer bands and being several times larger (Physically) than the rigs these days, they are still functional and even the lower power unit can easily handle a KW of SSB.? The older rigs ran AM modulation and the amount of instantaneous output power was quite substantial
