the final.
That radio also used a variometer as an ATU, it was a very quick and
reliable means of coupling random wires or verticals to the rig from 2-8MHz<


I had forgotten the 19 set - mainly, I suppose, because I never had a very high opinion of its performance!!! But yes, it had a variometer in series with the antenna.
Other than in the 500kHz region, I never saw one used in a tx over 100 watts or so, although that doesn't mean a lot. There may well have been QRO tx's at HF that did.
