#C4FM DIGITAL MODES HAM RADIO PLUS#

You may not like that, but can save the hobby and bring youth back to an antiquated hobby. Heck you do no teven need a HT on the commercial side, any cell phone will work with BeOn app. Here is the real threat digital VHF and UHF repeaters bring to hams, or the delight if you are a younger ham hungry for modern technology, is it can replace all that expensive HF space robbing equipment allowing you to talk to anyone, anywhere, anytime with data with nothing more than a inexpensive HT like a CELL PHONE already does. Not only can any radio talk to any other radio anywhere on any frequency band, all can talk to local police, sheriff, fire, gas utility, water utility and Homeland Security. I currently work for a very large electric utility designing a massive P25 Phase 2 system that cover 9 states with over 220 towers and unknown number of mobiles and HT's in the thousands.

P25 Phase 2 still uses the same 12.5 Khz bandwidth but TDMA allows for 2-voice channels (6.25 Khz), 1 voice plus data, or high speed data.Д«eing digital modulation uses less power thus extending battery life especially important with HT's and towers when power is knocked out. P25 Phase 1 can be either Voice or Data with very high error correction. As of today Public Safety, military, and utilities have all but completely abandoned conventional FM and use EDAC's, P25 Phase 1, and all migrating to P25 Phase 2.Д®DACs and P25 Phase 1 use C4FM a FDMA modulation is a 12.5 Khz or half that of conventional FM allowing twice the amount of channels. Battery efficiency for battery operated HT'sД¬onventional FM just cannot compete. Seriously doubt C4FM aka FDMA wins out of the digital modes, but with absolute certainty a digital mode will take over as it has already done on the commercial and public safety side with good reasons.
