<DIV>John,</DIV>
<DIV> </DIV>
<DIV>I'm not surprised the manufacturers keep the PCM information (like
packet specification, operating parameters, etc) private. For one,
that information could be considered a trade secret and they would not
want competitors to know about it. On the other hand, they might be
worried that a competitor would examine the data and discover some flaw or
limitation in the technology and then publicly announce this fact. Still,
I'm surprised no one has reverse engineered the PCM data stream from
either JR or Futaba (maybe someone has, I just don't know).</DIV>
<DIV> </DIV>
<DIV>I'll take some issue with what you have said regarding the technology
not changing since the '50s. I believe the '50s saw super-regen systems?
After that, there was (is) super-heterodyne systems. Then, dual conversion
and narrow band systems, as well as FM instead of AM. PCM was added
(really nothing to do with the RF, just a data link added to the existing
RF systems). I think the systems today are more reliable than in the 70s
when I first started, and they are having to do this in a much more
polluted RF environment.</DIV>
<DIV> </DIV>
<DIV>Still, I agree with you that, as a group (modelers in general), we
have not done a good job demanding more from the manufacturers. For most,
cost seems to be the big issue, but we don't look at cost in terms of the
big picture, like "a cheap receiver will cost you a lot AFTER you buy
it". Those of us that are competitors do a better job demanding
more, IMHO.</DIV>
