Quote from: GG on April 27, 2011, 09:01:10 AMIs there any way to adjust the ringing frequency output?Reason why is: all those pesky party line ringers (harmonic/decimonic ringers) that turn up in AE, SC, and Kellogg phones, that otherwise have to be de-tuned and still don't work quite right. The way to use it would be: Across tip & ring, wire an AC relay in series with a capacitor, that will close during ringing. Then connect the external ringing generator across the spare pair (yellow & black), and wire the frequency ringer across yellow & black in the phone. (It may also be possible to use tip to ground or ring to ground for the ringer, if both AC signals can share one wire in common without trouble.) With an adjustable frequency version, you might have a little trimmer potentiometer in the unit, and you'd hook up the phone and adjust the trimmer until the phone was ringing nicely.

I ask because I would like to use a WE2500 in place of the standard issue Rauland phone.Why do I want to do this? Because I want my phone to ring - not chirp!
