Yaesu thinks the future of ham radio is digital

A Digital Communications GuideYaesu thinks the future of ham radio is digital, and of course, that amateurs should adopt its digital mode (C4FM) over Icom’s (D-STAR). At least that’s what they say in their latest publication, A Digital Communications Guide for Amateur Radio Operators.

This publication claims several advantages for digital communications techniques, including:

  • reduced bandwidth,
  • digital data transfer,
  • better performance,
  • immunity to interference, and
  • product and system cost reduction.

It talks about some of the theory behind digital communications, explaining in relatively simple terms how the various modulation techniques work. Of course, it slams D-STAR:

Now, this method [GMSK] is considered old fashioned and no longer used by LMR [land mobile radio]. Currently, GMSK is still being used by D-STAR.

One problem I have with this publication is its implicit assumption that digital is better than analog, and that if we want to be “progressive” amateurs, we should all adopt digital communications techniques. I’m not all that convinced, and to its credit, Yaesu does concede that “analog FM can show an advantage over digital radio in some areas.”

I haven’t compared prices, but if the D-STAR radios are any indication, the prices of Yaesu’s digital radios are bound to be more expensive than the analog radios. I just don’t see that the added functionality is worth the extra cost.

What do you think? Do you think D-STAR or Yaesu’s C4FM will gain widespread acceptance anytime soon? Do you currently own a digital radio? If not, what would convince you to buy a digital radio?
