Explain something to me everyone:
I've had a practically brand new connex cx3400hp on my desk the past few days. This radio was not hacked up at all. My bench is running 14.1v dc.
R238 is still intact and the value is just what the schematic says.
R249 still intact.
TR32 is still intact.
TR53 is still intact.
There was no diode/resistor on the reg.
No mods no where.
It came in because of low power. I replaced several things.
Passthrough Regulator (tip36c)
AF Regulator (2sa1012-y)
2 - 1000uf 25v
1 - 330uf (beside passthrough)
1 - 100uf (C190)
both bias caps (1uf and 2.2uf)
All 3 mosfets (vishay brand)
Driver bias vr (100k)
Biased all mosfets to 3.80v
Realigned rf stage
Cannot get any more than 30w out of it, no matter what I do. I even tried removing R249, same watts. I even tried the diode/resistor on the collector of the passthrough, no change, same wattage. Tried a diode and resistor at the R238 location, same thing. I tinkered with the coils a little, no change.
How in the heck are you guys getting 50w out of these 3400hps?
Now, I'm using a peak reading meter, not a pep meter and 30w peak (X) 1.414 = 42.43w pep. But I hear people saying their dosey or pdc (which are peak reading meters also) is showing these radios doing around 50w peak on their meters, how?
