RE: Radio Controler
Tho some may not agree- This fellow's inquiry is a typical example of why I jumped to DX7 radio
Before that however, I used 53.xx exclusively -(KA7PON) simply because so many older pieces of equipment are floating about and it has become a crapshoot to use 72:xx.
This is not idle chatter - I have encounterd exactly this at our field in past yeras
Typical example is - dad's old radio plus new RTF model -
also Dad's old radio plus a rc car (most common.) some got unhappy and went away mad that their setup was not acceptable -even tho they realized "why"
some just went away-- (looking for another place -they WERE going to use it ).
Years back we shut down a local "hero" who decided Ham radio license stuff was not enforceable .he got a personal visit at his home from the Federal Inspector.
One last shot
If flyers at the field do not clamp down on every single example of improper use of frequencies - everything turns to sh-t-in a heatbeat.
