Topband: RESOLVED: Help needed with RTR-1A

[Mark Lunday]

Thanks to the 15 or so hams who contacted me offline to assist with this
issue.  The resolution:

 

1.       The RTR-1A units are working fine (no surprise there)

2.       It is NOT operator error (BIG surprise there)

 

After some more research on different message boards, and a great discussion
with Rod at DX Engineering, I learned that the TS480SAT 8-pin mini DIN
connector ground does NOT connect to chasis ground!  Therefore, the RTR-1A
won't function as I was trying to set it up.

 

Thanks to Dan, YO3IRM, I was able to get the unit hooked up and working
perfectly.   

 

For any other hams using a TS480SAT, see the attached GIF for how this was
resolved.

am trying to set this up for a separate receive antenna.  I had it working
with my Flex 3000 before I sold that rig.  Now I am trying to use it with my
TS-480SAT.

I actually have TWO identical units.  Both are exhibiting the same behavior:
without even connecting the RCA ground plug, I cannot get the units to
switch between receive antenna and transmit antenna using the toggle on the
front of the unit.  (I think that's how I accidentally ordered the second
unit 6 years ago, I thought the first one had an issue after moving my
shack, but somehow I hooked everything up and it worked fine).

I can receive RF from the transmit antenna jack through the RTR-1A to the
TS480.  This is the default behavior with power off.  With the power on, I
see the same behavior for both units, and regardless of the toggle setting
on the right hand side (RX ANT or MAIN ON).
