I just want to thank everyone who advised me to buy the RF Parts 3-500ZG tubes for my SB-220. I am very pleased with the tubes. I have about 20% more output power and it is almost unbelievable how mu

I think the soft part of the name comes from it taking little power so the weak outputs of a solid state radio can key it without damage to those weak outputs. Can you measure 20% at the other end of

I appreciate the comments of both Gerald and Rob. As a practical matter, a fraction of a dB is insignificant, however none of us would accept this degradation in the output of our transmitters, yet w

Just a couple tenths voltage drop in the 12 volt supply to the PA will cause that much power drop. Can't always get around it, besides it still can't be detected at the other end of a path whether lo

In the real worl of Radio broadcasting few CE's would try that.. All the GM's I worked for wouldn't tolerate a transmitter running at less than 100% or less than maximum allowed modulation. Advertisi

Hi Jerry, It's not about dBs; it's about paying your money and expecting a certain level of performance and having the product deliver that. You don't _have_ to run it flat out, but in the case of am
