[Johnson] JOHNSON KW MATCHBOX

[C E]

So about the ham that you know who did this and used
the internal antenna relay to switch in the extra
capacitance, added a line cord, and just plugged it
in...or used an inline switch to operate 160...

Was it good or was it not? What was the result? Did he
like his operation or did he confine his matchbox to
the junkpile because it didn't work? Inquiring minds
want to know...
