[Drakelist] Power output difference between T-4XB and R-4A PTO's

Curt, Thanks for the answer. I'm using the cable with metal tag for the injection. I haven't tried tuning up the T-4XB without it plugged in -- I'll give it a try an see what gives. If there's no difference, that would eliminate the cable as the problem. WW8X Joe __

[Drakelist] Power output difference between T-4XB and R-4A PTO's

When I tune up using the T-4XB PTO on 40 meters, I'm getting about 60 watts maximum. When I tune up using the R-4A PTO the power output is 95+ watts maximum. There's also about a 10 db difference in receive between the two units, the R-4A being the stronger receive of the two. I am using original D
