The radio folding back power for a high swr will prolong the finals' lives
but will not stop damage, RFI, and other issues caused by running a radio
that way. You still would kill the finals if you do that regularly and
depending on the radio's finals, it would happen faster than you'd think.

>> Hello, again, everyone.
>>
>>
>>
>> Well, on kind of a whim this afternoon, I wrote to Don Terrell of Alpha

>>
>>
>>
>> Here's what he said:

>>
>>
>> Hi Tom, I have read your e-mail carefully. I think the RV roof, being

>> TNX and 73,

>> Don, W8AD

>> So, now, this brings me to another thought:
>>
>>
>>
>> I have an old MFJ 901B manual versatuner that is not being used for

>>
>>
>>
>> Could I use that to basically tune the antenna, using receive noise as my

>>
>>
>>
>> I have always heard that doing this would cause the tuners to work

>>
>>
>>
>> Of course, I do have an LDG TW1 talking SWR/watt meter at the home qth,
>> but
>> hate to tear things apart to use it during the relatively short times

>>
>>
>>
>> Does anyone have any wisdom on this latest idea?
>>
>>
>>
>> I have also asked the question to Don Terrell himself.
