[Yaesu] FT-1000MP back from YAESU

 160m-Transnitting Spurious                                                
 --------------------------                                                
 Three FT-1000MP were sent back to Yaesu-Germany because of the transmit   
 ting spurious problem, reported earlier.                                  
 All these 3 radios showed poor spurious attenuation while beeing used in  
 the 1820..1826 frequency range. Local stations 20 miles away detected the 
 spurious while transmitting barfoot.                                      

 Yaesu now claimes they have realigned the unit and improved the spurious  
 signal attenuation by additional 10dB. Mine came out with -67dB, the other
 rig -66dB and the third unit is supposed to be at the -70dB level.        
 You know the signal strength of your neighbor. Subtract 60..70 dB and you
 have the strength of his spurious when using the FT-1000MP. I hope very 
 much not to get any more  spurious signal reports from outside Germany 
 as long as I still use the 1000MP.

 We were also told, there is no way to further lower the spurious output.  
 If these numbers are true, there should not be left much of a problem.    
 Who knows what other spurious will pop up now after the units were        
 optimized for 160m use?                                                   

 Erratic Clarifier Problem                                                 
 -------------------------                                                 
 My radio showed a very erratic behaviour. While trying to spot a caller   
 the frequency and the display jumped all over the place. This problem     
 was reported by others also.                                              

 Yaesu did replace a little (cheap looking) thing, what they called an     
 encoder. It looks much like a very cheaply made potentiometer with no     
 stops. It is the thing you use when turning the clarifier knob. I do not  
 think it is a real optical encoder. They obviously have replaced the more 
 expensive optical encoder by some cheap potentiometer and a tricky but    
 less expensive electronic.                                                

 Well, they replaced it and so far it does work as one expects a clarifier 
 to work.                                                                  

 I do not trust the 1000MP anymore and will replace it somehow. I probably 
 return to some radio which still has a real S-Meter with a pointer and    
 scales. This is what a radio should have anyway.
