[RTTY] More on RM-11708

[Terry]

From: Terry Gerdes, AB5K and Dan White, W5DNT

 

 

As many of you know, RM-11708 (the "Proposal") has been submitted by the
ARRL to the FCC as a "rule making" request. If approved, wide band digital
modes of up to 2.8 KHz bandwidth would be allowed in non-phone bands,
potentially impacting traditional CW & RTTY frequencies as new digital modes
are developed.

 

 

This Proposal would not alter FCC Part 97.221, which limits "automated
stations" to a small section of the digital bands. An exception is granted
in 97.221 for modes of 500 Hz or less, so the Proposal should not create new
automated wide band stations in CW & RTTY bands. However, as modes develop,
we would certainly expect wide band peer to peer communications to pose a
serious threat to our traditional CW and RTTY frequencies if the proposal is
approved by the FCC and no stringent band plan is developed. Once the
Proposal was made to FCC, the ARRL acknowledged the need for proper detailed
band planning to mitigate potential detriments to CW & RTTY. In early March,
they began a one month process of soliciting member input into that band
planning process.

 

 

As avid CW & RTTY DXers and Contesters, this potential threat posed by the
Proposal, coupled with limited time remaining for member input (through
March 31st), has caused us to have extensive communications with ARRL
leadership to insure both CW and RTTY operators are represented in this
process. This has occurred over the last two days.  We are happy to say
those conversations have been constructive. HOWEVER, those discussions
certainly do not constitute a fix in our minds. WE NEED YOUR HELP!

 

 

What is needed is for each of you to submit your own input into the process.
Besides, you may or may not agree with what we have provided. 

Please make your input constructive and specific, listing any bands and
frequency ranges you would find acceptable, if any, for wide band digital
modes. The objective here is to generate as much input as possible for the
HF Band Planning Subcommittee, chaired by Rick Roderick, K5UR. Rick, an avid
DXer and Contester himself, has assured us that all input will be
considered. That doesn't mean agreed to, but it will be considered. All that
we can ask for is objectivity and fairness.  After our discussions, we
believe Rick will bring that to the process.

 

 

What we don't need is more non constructive ARRL bashing, there has already
been plenty you can rest assured. We need to quickly mobilize and help look
for a solution. RM-11708 is not going to be withdrawn as the ARRL is
convinced the FCC is going to address wide band digital with or without ARRL
input. The EMCOMM crowd pushing for wider bandwidths is not going away
either and you can bet they are providing highly organized input. After all,
technology is changing, and with it, creative well reasoned solutions are
going to be required. This is time for us to step up to the plate and get
involved.

 

 

One point requiring further clarification involves the current automated
stations that have generated QRM for so many of us. These stations are
typically narrow band Winlink stations, operating under the frequency
exceptions granted by FCC 97.221. We would suggest that you consider
including these automated stations in your recommended band plan input.  We
strongly recommend they be limited to a wide band area due to their
extremely high inherent potential for QRM to RTTY, CW and even the case of
40M DX SSB split operation as some of us experienced with FT5ZM.

 

 

Thanks for your consideration and we appreciate very much any specific and
constructive input you may have to the Band Planning Subcommittee. 

Please address your comments to them via email at HF-Digital-Bandplanning at
arrl.org . As Chairmen, Rick Roderick should be copied. His published
QRZ.com email address is K5UR at aol.com .

 

 

As a sample, below is one letter of input for your consideration. We are not
asking that you agree with it, rather the letter is provided merely as an
example for your consideration.

W5DNT Input March 3rd, 2014

 

 

Ladies & Gentlemen,

 

 

As an avid DXer, while I am very concerned with the outcome of the 

petition process, I am pleased that ARRL has asked for comments with 

regard to Band Planning. Not only am I an avid DXer, but I am also an 

EMCOMM person, holding the job of ARES Emergency Coordinator of two 

counties in Texas, and a County RACES Radio Officer in one of those 

counties. I am proficient in RMS Express and have it on my PCs. Perhaps 

this will make the point that I am not just another upset DXer! As 

requested, my "cogent and thoughtful" input is respectfully provided 

herein. It is really very simple and can be boiled down to one sentence. 

Keep the wide band digital out of current customary CW and RTTY bands.

 

Translating that simple sentence into possible sub-bands, I would 

suggest as a starting point: 1.880-1.900 MHz, 3.590-3.600 MHz, 

7.100-7.125 MHz, 14.115-14.125 MHz, 21.115-21.125 MHz and 28.125-28.150 

MHz. NO WIDE BAND USE on WARC Bands (30M, 17M or 12M) as those bands are 

already too crowded! That would be a good starting point and would 

provide plenty of diverse spectrum without exposing CW and RTTY 

sub-bands to wide band digital QRM. Hopefully many others from the DX 

and Contest Community will provide input and the ranges can be tweaked 

as needed. Also, hopefully ARRL will seriously consider the desires of 

existing DX and Contest enthusiasts, and not just primarily the EMCOMM 

folks and software/hardware manufacturers frustrated with the current 

nuances of "broad band internet" style email over HF spectrum.

 

Just so you guys know, the other day on 40M with FT5ZM, one of these 

automated RMS Express stations was on the transmit frequency of FT5ZM in 

the foreign phone band, while FT5ZM was working split SSB. Did the users 

check to see if the frequency was busy with SSB traffic, NO! They went 

right ahead with their email traffic and essentially jammed the DX 

station for well over an hour. Possibly being "no-coders", they may not 

have realized RMS Express was signing each transmission with their 

callsign. If serious band planning is not done in earnest, this can 

easily become a routine problem for the RTTY and CW bands too.

 

With regard to Amsterdam Island and the digital jamming that occurred, 

that jamming cost me a 40M SSB QSO, along with many others. That 

DXpedition had an operational cost of $20 per minute. As a major 

financial contributor to FT5ZM, I am disappointed to see jamming of any 

sort, including the RMS Express situation cited above. Perhaps we should 

really consider the appropriateness of email systems on HF, particularly 

broadbanded modes.

 

 

Am I concerned about implementation problems if the petition is 

approved? Most definitely, yes I am. ARRL now has a chance to avert a 

spectrum disaster through good old fashioned common sense. Simply keep 

the wide band digital out of current customary CW and RTTY frequencies, 

through proper band planning. It is just that simple!

 

 

Respectfully submitted with Best 73!
