RF can make a problem in any where.
My FT-897D with AT-897 tuner is giving problem, i asked
on forum, every answer was aboput RF, RF is giving problem.
The remiday is properly ground, properly sheileded and should be properly Synchronize with other, other vise it can give you a big problem.

Anyway, if you did all above with it, It cover RF.

However, Rf is in the shack now.

What do you mean RF? Are you talking about stray current or RFI? For both you need to ground your antenna, the coax shield, the power supply. Unfortunately, not a single house in Swabi has been grounded. I hired a noted electrician for my house's setup. He's been in the business since I remember. Upon my last visit, I experienced electrical shock on computer CPU, stabilizer, PS and radio. I went over to him and asked him if he has run a grounding wire. He said he would have done so if I had asked and that he has 'never' done any. How terrible!
