[DX-CHAT] Hi Can anyone help

2005-09-12 Thread mike giddings
Would like to write to any Hams who have owned and used the Yaesu FL2000 B Linear amplifier. I recently purchased one of these secondhand and despite the age is in good working order. My only problem is that when the amplifier is switched on, but in standbymode (not transmitting) I get bad picture wobble (side to side)on my PC monitor (CRT type not LCD). Am not sure if this is caused by the high electomagnetic fieldfrom the big power transformer or interference from the two blower motors. Has anyone experienced this and any ideas on effective suppression.

Thanks and 73 from G'Land

I think you are on the right track. A strong 
electro-magnetic field from the amplifier.

Sometimes a shield (steel plate) between the source 
and the monitor will eliminate the problem.

In my previous working life weused Mu-metal 
shields between electro-magnetic souces and video monitors.

Distance is the least expensive cure (move the 
monitor away from the amplifer).

Mike:

I used to have an FL2100B and used it right next to the monitor for my 
dub terminal I used on packet and over the air DX clusters.  Nary a 
ripple that I could see.
