[AMRadio] Viking Ranger Plug - Adapter BEWARE!!!

Everybody  - 

This IS a safety issue!
John is absolutely correct, and I stand 100% corrected.

Do NOT use the adapter I described for the Viking Ranger.

Must have been a long day for me too - - without giving it much thought I was 
describing the adapter I made for my Drake, where the power supply needs a 2 
similar pair of pins to control the amplifier relay (that's why I mentioned 
power supply).

But the HUGE difference as John points out, is that although the connection on 
the Drake simply closes a couple of contacts...the Viking Ranger puts line 
voltage on those pins.  BE CAREFUL WITH THIS.

Thanks for the correction John.

73!

I don't have a Ranger schematic to reference but on the Viking II,  one pin of 
this ceramic antenna relay connector is connected directly to  one side of the 
incoming AC line. Should you still have one of those double  fused "death plugs" 
on the line cord, either replace the cordset with a  polarized, properly 
connected cord set or better yet, a 3 wire cordset. Again,  make sure of your 
polarity. An American set will have a green lead  that should be connected to 
the chassis, a black wire that should be  connected to the hot side going 
through the fuse holder and a white lead  which should be connected to the 
return side. Computer cords will have different  colors so meter them to be sure 
you know how they are connected to the AC  plug.  The wide blade is hot.
 
Regardless, you are dealing with line voltage and the RCA connectors are,  for 
the most part, not rated for that use, regardless. Use a connector approved  to 
handle your local line voltage or you are inviting serious problems.
 
Again, if you have one of those fused plugs on your rig, ANY RIG, cut it  off 
and throw it in the circular file. You have only one life to live.
 
73 and stay safe,
