[digitalradio] FCC Technology Jail: ROS is Dead on HF for USA Hams

As I previously predicted, an FCC agent has interpreted FCC Rules, saying ROS is Spread Spectrum. ARRL staff have also done the same. In the FCC response to an inquiry initiated by Timothy J. Lilley - N3TL, The FCC Agent 3820 stated this: ROS is viewed as spread spectrum, and the creator

I have a different take on this. There are a number of modes that uses vertebrae coding which could be mis-described as spread spectrum by some. The problem with part 97 is that it tries to be as broad as possible where technical parameters are concerned. In this case it causes things to be vague.

The distinguishing characteristic of spread spectrum is spreading by a code INDEPENDENT of the data. FM for example, creates carriers depending upon the audio frequency and amplitude. SSB creates carriers at a frequency dependent upon the tone frequency, and RTTY at a pair of set frequencirs

I think I have it working, but haven't heard any signals or tried to contact anyone yet. What works is that if I punch CONNECT the transmitter gets keyed and I can hear signal bursts going out on the sidetone. And I guess I am receiving audio because I'm getting a bunch of garbage on the screen

Convolutional coding and Viterbi decoding may increase the occupied bandwidth but they also decrease the amount of power required to communicate. In some cases, like trellis-coded modulation, the bandwidth stays the same even though the power required decreases by a factor of 2-4. Spread

It is a NECESSARY AND SUFFICIENT requirement (out of three). The point is that if that is not the way the spreading is done in ROS, ROS is NOT spread spectrum. PROVE, not just claim, that it is not, and the battle is won. 73 - Skip KH6TY Rik van Riel wrote: On 02/23/2010 09:00 PM,

There is now only 4 options, for USA hams who still want to use ROS on HF bands: 1. Operate ROS... knowing that you are breaking the FCC Rules, and roll the dice, hoping you don't get caught. 2. Go on an uphill battle to change the FCC Rules, and possibly win or lose after a year

OK, I am starting to agree with Dave now and with Andy as before ... this is starting to now become circular . It has now been solidly established that ROS is FSK, NOT SS, by the authors own words. The author NEVER approached the FCC for an OPINION about his unfinished work at all.

In order for amateurs in the U.S. to use any RTTY/data mode other than Baudot, ASCII or AMTOR over 2FSK they must be able to point to a published technical specification for the potocol that shows that it is legal. It was condition that we all agreed to when we were issued a license. When this
