Hi Skip I have been monitoring a ROS idling over time using DL4YHF's Spectrum Lab. Here is the results.You can clearly see a pattern 73 de LA5VNA Steinar On 26.02.2010 12:29, KH6TY wrote: Alan, Of course, the FCC rules on SS are outdated and ROS should be allowed due to its narrow

That's a good analysis, Steinar. Is it possible to see if the pattern changes when sending data? That is all the FCC is concerned about. The pattern has to change when sending data and not just remain the same to exclude it from being FHSS. 73 - Skip KH6TY Steinar Aanesland wrote:

Hi Skip Here is the new ROS signal. It is idling with two gruops of 25 sec of X's . As you can see the pattern change when sending data. http://home.broadpark.no/~saanes/bilder/ROS_X_2.JPG 73 de LA5VNA Steinar On 27.02.2010 13:19, KH6TY wrote: That's a good analysis, Steinar. Is it

Looks like good news Steinar! If the data changes the frequencies, it does not qualify as FHSS as Jose originally claimed. I am sure the FCC will find the same during their tests and expect them to say it can be used on HF and VHF. I am especially interested in being able to use the 1 baud

Hi Skip First , I have read all of your mail's and I think you have argued fair and square. I can't tell if ROS is FHSS or not . This is to complicate for a country boy like me, but I really hope that FCC will let you use narrow band SS on HF some day . Cross my fingers for you and 73 LA5VNA

The FCC will say that it up to each licensee to check the legality by reading the new technical specification. Unless someone shows that the spectrum doesn't match the specification U.S.hams should feel safe using ROS. 73, John KD6OZH - Original Message - From: Dave Ackrill
