Hi Paul,
I used a couple of web controlled receivers and notice the modulation was low, I turn't up the volume just before I switch off about 22.20pm. Dont know if you heard me at that time? I dont think I have trouble with parasitic oscillations anymore which cause the warble type noise and distortion. (Glowbug I totally agree with you about ferrite beads)
Keep an ear out tonight I will probably test again with the modulation a little bit louder (Hopefully not distorted)
Thanks
Joe
