[TowerTalk] FOLLOW UP & SOLUTION ..RE Quiet 27" monitors ?????/

[Gedas]

I do not have the model number handy (shack downstairs, me upstairs in 
recliner with injured back) but I run a pair of 6-7 year old 27" (I 
think) Samsung wide monitors and love them, EXCEPT for the times when I 
run QRO on 40m HF which gives the capacitive on/off touch switches 
grief. These monitors can be turned on and off via a touch with your 
finger and when running a kW or a little more I find them turning on and 
off uncontrollably as I talk via SSB. Lower power is aok. This means I 
have some RF floating around in the shack but would not have guessed so 
as only these monitors detect my HF operating.

This is why some people appear bright until you hear them speak.
