Submission Comment #2 W5RH Looking at a bit more detail in Appendix E (Page 74) their study shows available frequency ranges within 2 to 25 MHz. None of their proposed bands cover any of our ham bands *EXCEPT 60 Meters, where we have 5 "channels",* but I think this is shared anyway.
Their 10, 25 and 50 KHz "channailzed space" ranges come up to the band edges on a few ham bands NOT JUST 20 MX as has been blogged and youtubed. Below I have outlined where their study touches our band edges (always skirting our bands except 60 mx). They claim throughout that they want to cause NO Interference to existing services (ham, marine, etc.) Their study indicates these Frequency bands available 2 to 25 MHz (ref our bands).... *Below Above * *3.4 4.0 80 is 3.5 to 4.0* *5.4 5.0 (within 60 meters 5.3 to 5.4)* *7.0 7.4 40 is 7.0 to 7.3* * 9.995 10.15 30 is 10.100 to 10.150* *14.0 14.350 20 is 14.0 to 14.350* *18.068 18.168 17 is 18.068 to 18.168* *21.00 21.850 15 is 21.0 to 21.450* *24.89 End 12 is 24.890 to 24.990* Looked up in the license database. None of the commenting parties is a ham except maybe John Madigan (AC0GP -- maybe). Also, have a look at what they intend to do. These shortwave HF links are to benefit High-Frequency stock trading. (high frequency is not meaning RF but the speed of the trade data xfer). Using shortwave will reduce the latency times for the transfer of applicable stock data. Not using satellites or the internet will cut milli seconds off of their transfer times. HFT is a crazy way to trade stocks.. Google HFT and read on Wikipedia. 73...Rick W5RH On Sat, Jul 15, 2023 at 6:43 PM Rick Hiller <rickhille...@gmail.com> wrote: > A cursory read through the proposal and attached amendments shows that > they have done their homework in all aspects.
