Kenwood TS-450S won't load on new 20M dipole.

I just made and installed a 20M dipole (with 1:1 balun). The TS-450S loaded with no problems but after several transmissions refused to even come close to doing so. I've checked the antenna and all looks fine. Any clues?

Surely you've checked connections, etc.----could balun have gone bad? Also are you using an external tuner? Lots of MFJ tuners will "screw up" once in a while. Open it up and inspect it

TS-450S Noise Blanker, No 1 & No 2 neither has any effect on noise


The noise blanker settings on the TS-450S (and S/AT) are true noise blankers and should not be thought of as a DSP device or something that they are not, like a notch filter or IF shift and etc. They will do a fine job of eliminating ignition noise as well as eliminating the electric mixer or blender noise from the kitchen...... however they will not remove static crashes or quieten those atmospheric noises on 75 meters during summer time thunderstorm season activity.

Hope this helps!

Kenwood ts-450s - cannot tune and no ptt


This is usually due to a stuck or shorted ptt line. I have repaired a couple of these and it was the same component each time. The packet TX transistor Q65 shorted causing the radio to power up in TX inhibit mode. Transistor Q65 is located on the underside of the IF board under the ACC 2 connector. This switching transistor is used only for tx (pin 9 of acc 2) and no other circuits depend on it. It can be removed completely if you don't mind not having ptt on acc 2.
This seems to be a common problem lately, I hope this helps you.
