> I wrote an article (CQ, Nov. 1960, pg. 71) on modifying the TCS
> transmitter antenna matching network to pi network by replacing the
> original tank-coil/variometer by adding a 300-600 pFd bc type variable
> condenser connected to the output end of the original roller inductor. The
> bc variable condenser is panel mounted in place of the removed output
> coupling variometer - thus panel lettering 'coupling' remains relevant
> but now refers to the coupling condenser.

> I've used this modification for years and it works well into coax and
> end-feds.
> I can mail a scan of the article via meils at get2net.dk
