Removed EMI on Phone  Time owned: 0 to 3 months
My neighbor complained about hearing garbled sounds over her phone when I was transmitting 100 watts SSB on 20 & 40 Meters. I verified the problem and tried ferrite chokes & a Radio Shack phone filter, which helped slightly, but not enough. I bought a K-Y 2 line filter from HRO, installed it at the phone and; no noise!

It is speced at ~40 dB rejection and I believe that is conservative. Will get several more to solve any future similar problems, which seem to come from too much R.F. too close.

Easy solution to big problem.  Time owned: 6 to 12 months
My cheapo wall phone always seemed to turn into a great receiver every time I hit the transmit switch. Adding the KY RF-1 eliminated the problem. Enough said!
