Just got a new DX500V from copper today. Attached are a few pics of the DEI’s being used. Here’s a couple of measurements all taken on the Bird 43P.
1 Watt AM input....110 output...dead key
2 Watt AM input—-150 output...dead key
3 Watt AM input....200 output...dead key. Draws 32 amps at 13.8 volts. As measured by the meter on my Astron VS70M which I calibrated to my. Bryman multimeter.
4 Watt AM input...245 output...dead key. Draws 38 amps at 13.8 volts
7.5 watts AM pep....300 output pep.
Final measurements on SSB.
17 watts pep SSB...360-375 pep output. Draws 42 to 44 amps.
If I bump SSB pep to 20-21 watts output is 400-410 watts.
The input SWR from radio to amp is flat 1.1
These measurements were taken using my IC-7300
