Recently I used the tuner to adjust the SWR to a low level for transmitting. The tuner functioned properly and the SWR level dropped to close to 1:1 . Later, I changed frequency sufficiently to know that I should retune. This time when I pressed the TUNE button I got the WAIT light but no change in SWR and no action I could detect occurring with the tuner. I switched the output to a 50 ohm dummy load. Turned off the tuner and sent CW at about 10 watts output. The SWR showed full scale. If I increased the RF output the limiting circuits in the radio cut it back to perhaps 35 watts of output. I checked the output with an independent power meter. The power out was at the level shown by the FT1000MP power meter. The reflected power shown by the independent meter was close to zero. The SWR shown on the independent meter was about 1:1.2 which was expected. The FT1000MP still showed full scale SWR. I would welcome any comments or suggestions from people reading this concerning how I might correct this problem.

I found W4FT's web site, which diagnosed the problem and provided a cure. Cliff will even provide replacement diodes for the failing/failed ones. It cured my problem! And, it appears my FT0000MP works, as well as, or better than new.

The problem was ?pilot? or ?operator? error. I operate a rather complex SO2R station where all of the antennas are distributed correctly to each of the radios as a function of the frequency the radio is operating on. When one changes bands on either radio the correct antenna for the band is routed to the radio automatically by circuits that decode the band and select the correct relays in a relay matrix to activate. Naturally, there are protective circuits to prevent both radios being able to access the same antenna at the same time or operate on the same band at the same time. Somehow, someone [we know who the someone was ] manually selected the band for the ?failing? FT1000MP and bypassed the normal auto-band selection for that radio. That meant that the antenna going to that radio was the manually selected one, not the auto-selected one. The result was the SWR was more than 3:1 on every band but one and the good band was never one that I checked when testing. As a result the radio very correctly turned down the power. Once my early morning [ 6:00 AM Sunday morning here in Idaho ] testing of everything from the antenna to the radio was completed I had found the culprit [me] and corrected his stupid error. At various times in the process I had suspected many different things were failing; bandpass filters, relay selection matrices, relays, antennas, etc. I bring that up because I have found ? especially as I grow older, that careful testing of things before taking action can often save many fruitless hours of unneeded repair or additional testing of components that are not really failing. At this point I don?t try to fix circuits or equipment until I am absolutely sure that circuit or equipment is truly causing bad things. The good things that came out of my inquiry are the references that were provided by Ron, W8GUS, Bill, WD8ARZ and Lance, WN0L. I will be following up on your references to add them to my collection of FT1000MP notes. I truly appreciate your taking the time to assist me.

When the tech would say "I've never seen this before" I would get the "look" from my wife and I knew I was responsible. Don't get me wrong I applaud your innovation to push the envelope, ham radio has evolved and will keep evolving. From my simple station on the west coast I've hit the other side of the word and that's more than I thought I could ever do. I'm a VE for the ARRL so I can give something back to a hobby that has given me so much to me. For now I run 200 watts into a modified Mark V into a G5RV and a GAP Titan and that's good enough for me to play around with. 73 Roy AA6QQ On Sun, Nov 9, 2014 at 12:08 PM, Tod Olson wrote: > That is pretty good advice Roy.
