6146'S

[Edward B Richards]

Hi to you, too, Russ;
The commercial bands are LO-Band: 25 to 50 mc.; Hi-Band 132 to 174 Mc.;
and 450; 450 to 470 mc. All the major manufacturers used one or two
6146's in both their Lo-Band  and HI-Band transmitters. The common
ratings were Lo-Band: single ended 30 watts, double ended 60 watts.
Hi-Band was: single ended 25 watts, and double ended 50 watts. I recall
one Motorola model rated at 60 watts. This is the power out as measured
with a Bird thruline or termaline wattmeter at the antenna connector. I
don't know of any Heathkit radios using 6146's at two meters, although
you should be able to get 60 watts rms icas. I hope this answers your
question  (big grin).
