Here's the deal...I ended up with a Fatboy 5-pill. Installed it a couple weeks ago using a DX959 (DTB-tuned), RG-8 coax, and a 102" whip (SWR 1.1:1). I was getting between 100 and 125 dead key and 400 to 450 watts of swing (using a Dosy meter)...which I thought was about ideal.
Saturday I changed the setup slightly, I wanted to step back to a simpler radio (I hardly ever use SSB on the 959 because of the way the amp switches to SSB delay) and a different mounting location (front console to floor) because of a child's car seat.
I installed a PC76 (DTB-tuned) with a piece of Mini-8 to the amp, RG-8 to the meter, and RG-8 to the antenna. Barefoot, the PC76 shows less overall watts than the DX959 (by about half)...but the PC76 will get over 650 watts from a 100 to 120 watt dead key (as shown on the Dosy). There is NO swing kit in the PC76. I actually had to pull my intended meter from the setup (an Aries A-460) because its only rated for 500 watts (although it would read the 650 watts?).
What caused the change in swing? I see the only variable being the addition of a piece of Mini-8 between the radio and amp, and the radio?? Everything else is the same (the RG-8 is the same pieces I used with the 959, just rerouted). What is especially confusing is the fact the 959 shows more barefoot watts than the PC76...even when both are dialed into 100 watts on the amp.
Would this be a difference between a MosFet in the DX959 and a 1969 final in the PC76?
