6% is about 0.5 dB.? The difference won't be heard.?? Good to have protection for the times when something wasn't connected or the tuner wasn't or ...

I have more data.? I measured the power out on the Trusdx with and without the diode protection.? ?Here is the data: Band. W/diode. WO/diode. % lost 80.? ? ? ?5.96.? ? ? ? 6.35.? ? ? ?

Upon rereading Dave's post I think I? misunderstood what he said.? I think he said that he had never seen a final that was biased as he said not that he had never seen a final with a 1n4756a

Why is that better than the diode. What if you hook things up wrong and the antenna tuner is not connected?? Dave, there were no bad effects shown on the spectrum analyser.? Dave all of Steve Weber

I have a ZM-2 that I built. If anyone wants to borrow it to try it out with your (tr)uSDX or other let me know. 73 Howard N6POM

The best way to protect (tr)uSDX against high SWR is to use a proper antenna tuner like ZM-2 ATU that will protect the finals during the antenna tuning. [image: image.png] 73 Ned AC6YY

Connie, I agree completely. What is the effect on the spectrum, particularly on SSB, which may easily be distorted due to the diode. I think that the failure mode is due to the high voltage as the 3

I think we doubled on Vern. I think I may have added him to the group. Maybe you should be the one who answers the requests. Dave

Thanks Connie and Chris for your advice. I neglected to mention that the laptop is running Windows 7; i found that indeed there is a rich selection of free apps for Windows and iOS drive wiping. Best,

Howard, Interesting.? ? Thanks,? Dave

David, I will bring the Chameleon to Barry's on the 4th. I expect a full report on how it works (Hi, Hi). The cap doesn't look like an easy fix. I agree poor manufacturing quality. Dave W6VYC
