>> Hi, everyone.
>>
>>
>>
>> Well, last night, I got rid of the gremlin that was causing issues with
>> my
>> ability to play selected audio files using Winamp, but now, another
>> gremlin
>> has appeared in my shack.
>>
>>
>>
>> This time, I'm experiencing a very strange problem with my Kenwood
>> TMV71A.
>>
>>
>>
>> The problem occurs mainly when trying to transmit with high power on 440,
>> but it happens occasionally when trying to do so on 2 meters as well.
>> Basically, when I transmit with high power, especially on 440, the rig
>> shuts
>> off for a split second, but then comes back on. It's almost as if the
>> rig
>> is not happy transmitting on high power for some reason, again,
>> especially
>> on 440.
>>
>>
>>
>> I discovered this issue late this afternoon, as I was doing my usual
>> monthly
>> tests of equipment, antennas, etc., at least as best as I can from here
>> in
>> the shack at the home QTH.
>>
>>
>>
>> In trying to diagnose the problem, I have done the following things so
>> far:
>>
>>
>>
>> 1. My first thought was that something has gone wrong with my outdoor
>> Diamond X200 VHF/UHF antenna, which is fed with RG9913 coax and is on the
>> roof of my house at a height of approximately 35 feet. I took SWR, as
>> well
>> as forward and reflected power readings using my TW2. Both on 2 meters
>> and
>> 440, adjusting the meter for each gand as I went. my SWR's on each gand
>> are
>> between 1.2 to 1 and 1.3 to 1. On medium power, my forward power on each
>> band is between 9 and 10 watts, and my reflected power is either at 0
>> watts
>> on 2 meters, or point 2 watts on 440.
>>
>>
>>
>> 2. I then tried switching jumpers between my TW2, and the Diamond X200
>> connection on my MFJ window feed through panel. Again, no change.
>> Admittedly, I haven't swapped all jumpers out, but at least the initial
>> jumper swap didn't change the results.
>>
>>
>>
>> 3. I then did a V F O re-set on the TMV71A, with again, no change in my
>> results. I'm a bit reluctant to do the full re-set, but may do so as a
>> last
>> resort, since I have the TMV71A programming cable, and also have all
>> memories and menu settings saved in a data file for the rig.
>>
>>
>>
>> One other thing I might try is to see if this happens with the TMV71A
>> that
>> I
>> typically use when camping out at the RV. It is here in my shack in a
>> box
>> for the winter.
>>
>>
>>
>> Before I go too crazy with all this, though, I'd like to know whether
>> anyone
>> else has experienced this issue, and if there are other ideas out there
>> that
>> I might want to try.
>>
>>
>>
>> Thanks as always for the help.
