do it yourself tuning?
Thanks for the feedback guys..i know one has to be extremely careful about having the transmitter on tune but theres no reason why if..we perform the procedure carefully..that we shouldnt do it ourselves , after alll thats what a hobby is all about,and maybe the result would be even better because my doubt is that..especially in he case of mass produced cheap 4 channel units would benefit from reglar or careful tuning, after all those coils are subject ,,maybe to temperature related variations,,and maybe they are not tuned carefully in the first place..ie short rande or glitches with brand new cheap eqipment...it would be nice to have procedure bnluenotes from the manufacturars or from some experienced rf engineer in the internet..and ive heard of some addon computer boards that make a personal computer a spectum analyzer but dont know where to buy them..any ideas guys?
