I was just trying to keep it simple, 'logic language', instead of: 512 or 1024 PCM, positive or negative going, 1.2 or 1.5 ms neutral...you know, all the stuff thats been forgotten since 2.4 became common...Blimey, there are guys at the local club that have never known a single crystal, fixed frequency radio, and asking them about a peg board...I do remember that we recommended not to mix brands as what may work well at short ranges always seemed to cause problems when the model was a bit further away...but then we all remember that stuff, don't we?
