[MRCA] ART-13 Power Output Poll

[Christopher Bowne]

Just wondering what folks are getting for actual output power from their ART-13s.  Mine has consistently shown in the vicinity of 175 watts carrier output on my Heath HF watt meter, even into a Bird 500 watt dummy load (no watt meter indication on the Bird itself).  I have always thought this to be a bit on the high side of reality for a set powered by a DY-17A.  I get similar results with my T-195.

I know the nominal rating for the ART-13 is 100 watts out, but I think that was for loading into a low impedance aircraft antenna, should be able to get more from a 50 ohm dipole load.  I use a large high capacity variable cap across the TX output to allow for better control of the loading, the watt meter is downstream of this on the feed line to the antenna or dummy load.
