Re: [Flexradio] SWR MALFUNCTION

Still trying to solve my high SWR fold back problem.
 
One other Flexer (K6JEK) had a problem with the J3 on the REF board  falling 
out and producing similar results. Mine is plugged in and fine, however  if I 
unplug the J3 I get the same response Jon ,K6JEK did... completely  bogus 
power out and reflected reading on the console -- 568 watts...   My reflected 
power reading is much higher than forward power... on the  console, reflected 
power reads 5-6 times higher than forward power...  obviously not correct.
 
Any other recommendations on what to look for?

I have a  strange fault.  The SWR bridge in the SDR-1000 seems to be   
malfunctioning.  

While on the air this morning the SWR jumped  and there didn't seem to be  
anything I could do to correct it.   I checked the SWR with another  
transceiver 
and verified it was  OK.  

It seems the SDR-1000 SWR bridge is reading in error and  causes  the 
amplifier to fold back.  In the SDR Tune position  the SWR reads  50:1 on all 
bands 
even to a dummy load and folds back  even with 1 watt  drive.

Has anyone ever experienced this?   Any recommendations.

I don't believe it is a software problem.   System ran correct before  the 
fault, receives fine and same SWR  problem exists after re-booting the  
computer 
and reloading the  software.

Re: [Flexradio] SWR MALFUNCTION

Some time ago, I had a few questions regarding SWR metering. One of the
items brought out by Eric was that the SDR-1000 SWR metering interface is a
single wire on the parallel interface. The communication occurs serially
over this single line. Just how to resolve a problem in this area, I do not
have a clue other than to suggest you examine the connecions involved. In my
case I have the Z-100 turner and the above I would guess would also be true
in some measure if the tuner were not involved

try some ferrite beads on the interface cable between the SDR 1000 and your 
computer. Place them close to your computer as possible.
This solution worked for me.
