uhhh NO AMATEUR frequencies are in jeopardy of being grabbed, etc..Originally
the petitioners wanted 5,10,15,20 and 25 MHz...
SOUND familiar??? Look at the frequencies they propose now....not far off
WWV....now WWV uses KILOWATTS on their frequencies....don't cause issues with
ham operations....Its NOT a ham spectrum grab...

This has been coming for a long time. It is already being done.
It does seem like a spectrum grab. There are plenty of HF frequencies they can
use without interference to HAM radio.
ARRL will hopefully prove their worth this time.

Submission Comment #2 W5RHLooking 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 4.05.4
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 10.15014.0 14.350
20 is 14.0 to 14.35018.068 18.168 17 is 18.068 to 18.16821.00
21.850 15 is 21.0 to 21.45024.89 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.

A cursory read through the proposal and attached amendments shows that they
have done their homework in all aspects. The various companies have been
running experiments on air for the past 4 years. (experimental call signs are
listed) Seems like they wish to run 20KW to a 10dBi antenna on transmit and
have a simple vertical whip on the receive end. They also propose interference
avoidance and frequency jumping.... kind of like ALE. Freqs used were 4.9,
10.2, 14.9 19.9 and 24.8 with a bandwidth of 10 KHz.
In their initial paragraphs they mention avoidance interference to amateur,
marine and aeronautical. No mention of military in there that I saw.
Again, this was my 30 minute read of the various sections which means that I
was looking for pertinent information relating to us hams. I am sure there is
more to be found and corrected with a further read.
Just my $.02 for now.....73...Rick W5RH

Thanks for the reply Bill. As Jim Heath points out in this video, the
deadline for comment is two weeks away. My first thought is, we might (emphasis
MIGHT) be better off to express our immediate concern to the ARRL defense of
spectrum lobbyists, in hopes that they could help convey what they know to the
rest of us (beyond what's in the petition) to give Ham World a chance to weigh
in. But whatever we do we're already late in the process and big money backing
this plan already has a big edge on us, if there is something here to be
worried about. Any thoughts from others? Time is running out. Let's hear
it! JP

JP:
We may want to convene a committee of interested people to talk about what is
proposed. There are so many variables, not to mention the costs to construct
and run a digital transmitter. Also, who has digital receivers? Currently
there are limited AM shortwave receivers for that industry is dying (like the
majority of the over-the-air broadcast stations due to the ubiquitous and
massively increasing wireless internet)..
