![]() ![]() If it breaks, you will probably put out much less power than before, and you'll have to buy another 440 to get a replacement. It wont gain you much at all, and the chances of breaking it are very high. If it is clipped, solder it back together. I like 1.5K ohms, but if you are looking to experiment, try anywhere from 470-3.3K ohms and see what you like best.ĭo not clip the diode or other part that the "internet instructions" tell you to. If you want to get some additional modulation in that chassis, try messing with the value of R134. You will have to put out 400 watts to get to S-6. If you key up with 4 watts deadkey, and hit someone with an S-5, to get to S-6 you will have to deadkey 16 watts.ġ00 watts out of your radio gives them S-5? To gain a 1 S unit increase in someone else's receive, you have to quadruple your power output. No one would notice one single bit of difference in your signal if you were suddenly able to swing up to 25 watts instead of 16 watts. ![]() There is no point in replacing the final and driver transistors. If it were my radio i would replace all of the electrolytic caps just to be sure. There could be a bad cap in the audio section of the radio that would also cause that condition. Yes, a hum in the audio is many times caused by a bad filter cap in the power supply, but that is not always the case. ![]()
