New Post, re: receiver desense after transmit.
 
Hi all,  I recently wrote about my problem with the main receiver  
sensitivity on my FT-1000mkv-Field, 4 months old.  On occasion after  transmit the main 
receiver sensitivity drop drastically.  Sub receiver,  tuned to same frequency 
may read S-9 on the meter and works ffine,  but  main receiver may only read 
S-1 or below.  No controls or changing of bands  or frequencies change this 
condition.  Only a tap on the PPT switch on the  Mic or a touch of the MOX 
button can restore the main receiver to normal  sensitivity.  This problem seems to 
appear intermittently and if I use the  rig on a regular (every day) basis it 
seems to disappear or be very  intermittent.
 
This would seem to indicate a relay  problem.  Does anyone know  of a relay 
in the RX/TX circuit that only effects the main receiver.  My  age and 
condition of my eyes have precluded me from tracing it in the owners  manual 
schematic.  My 50 years experience tells me that normally only one  relay would be used 
in the rx/tx circuit to supply  signal, on receive to  both receivers but my 
symptoms indicate this may not be the case with the Field.
