Re: RF Interference From Old TV Caused Village Broadband Internet Outages for 18 Months

I posted this on another forum -
18 months of service calls, replacing the main distribution line... all before a technician takes a spectrum analyzer out into the field? Customer is blamed for the failure of inept field technicians. Time for that ISP to audit their field teams skillsets.

While the TV might be the source, it likely wasn't the cause. More likely that this was a bad line tap, a connector suckout, etc. that allowed interference to backfeed.

Hi Dennis,

I'm not sure what the best approach to take in this...  The twisted backronym name of the act that precipitated it, the
“Repack Airwaves Yielding Better Access for Users of Modern Services Act” of 2018, appears to me to be intent on reducing the current occupancy of the spectrum, in order to re-allocate ("repack") it for other uses.  Pointing out that the fee will accomplish that goal is telling them that they are exactly right in imposing it, for the purposes of the act.  That's not the outcome we want.

I think, perhaps, a better approach might be to focus on the value that the Amateur Service creates for the country, and that replacing that value through other services would be more expensive than keeping our community intact and vibrant.  Instead of instituting a fee, they should encourage the Amateur Service by removing any and all impediments to its growth.  If this is about money, what's better than free?

Just my opinion,

Greg  KO6TH

Are any of you familiar with the GRONK radio network (GRN)?  A lot of guys in the Sacramento area were the pioneers of this system back in the mid-1960's.  I believe it is primarily in Southern California now and involves multiple remote bases and other repeaters.

Anyway, they have a facility up on Jordon Peak in the Sequoia National Forest.  The fire down there destroyed the site.  Thought you might be interested to see it.  This is a risk inherent with radios in remote locations.  I hope nobody was hurt.

========================


There was mention this morning about the Gronk Radio Network site on Jordan Peak ... Matt and his guys had done a maintenance/upgrade trip there about a month ago, and all that work is gone.

The building was a wood structure, with metal sheeting on the outside -- solar panels on the roof.

Here's a picture of the site before the fire:

The GRN building is to the right of the lookout.
And, another view ..

Then, the "SQF Complex" fire rolled through ...

This is what's left of the lookout ...


And an aerial view - the GRN building (or what's left of it) is at the left of the picture, above the USFS solar panels.
The vertical "posts" are pipes that were used as supports for antennas.


Sad to look at ...



YGate -- turn your Yaesu FTM100 or FTM100 into an APRS packet igate, no extra hardware required.

Craig - KM6LYW
 

From the W6EK software development laboratory:

    https://youtu.be/uuyBmRwv38o

If you have a Yaesu FTM400 or FTM100, and a PC or Pi, you have all the hardware you need to create an APRS igate.  You just need one bit of software called "ygate" which translates the serial data output from your Yaesu radio, and converts it into APRS packets, then forwards them to the APRS information service on the Internet.  So why build an igate?  An igate listens to APRS packets on 144.390 (144.800 Europe), and relays them to the APRS Information Service where they're processed and relayed all over the world.  APRS can provide email, SMS, position reporting, and a host of other services.  You need an FCC/CEPT amateur radio license to use this software!

FYI: FCC Grants ARRL Rules Waiver Request for Fire Emergencies, Hurricanes

FCC Grants ARRL Rules Waiver Request for Fire Emergencies, Hurricanes

09/17/2020

The FCC has granted ARRL’s request for a temporary waiver to permit amateur data transmissions at a higher symbol rate than currently permitted by section 97.307(f) of the FCC Amateur Service rules. The FCC acted to facilitate hurricane and wildfire relief communications within the US and its territories.

Section 97.307(f) limits the symbol rate — the rate at which the carrier waveform amplitude, frequency, and/or phase is varied to transmit information — for HF amateur radioteletype (RTTY)/data transmissions to 300 bauds for frequencies below 28 MHz (except for 60 meters), and 1,200 bauds in the 10-meter (28 – 29.7 MHz) band. The digital signal must use one of the codes specified in section 97.309(a) of the rules, but an amateur station transmitting a RTTY or data emission using one of the specified digital codes may use any technique whose technical characteristics have been publicly documented.

In 2016, in response to an ARRL petition for rulemaking, the Commission proposed to remove the symbol rate limitations, which it tentatively concluded had become unnecessary due to advances in modulation techniques and no longer served a useful purpose. However, the FCC did not include the ARRL proposal to limit signal bandwidth to that which the Commission had said it intended when it originally adopted the 300-baud limit. The proceeding is currently pending.

ARRL sought the waiver for amateur radio licensees directly involved with hurricane and wildfire relief via HF using PACTOR 4 modems for communication within the US and its territories, relative to several impending hurricane situations and wildfires in the western US. ARRL’s petition noted that Section 97.307(f) of the amateur rules prevents the use of PACTOR 4, a data protocol that permits relatively high-speed data transmission. ARRL noted that past FCC temporary waivers have allowed this protocol during similar events. ARRL also stated that trained amateur radio operators with communications equipment are actively preparing to assist radio amateurs involved with the Amateur Radio Emergency Service (ARES) working with federal, state, and local emergency management officials to assist with disaster relief communications.

“We conclude that ARRL’s request should be granted,” the FCC said. “ARRL stands ready to assist the area potentially impacted by the impending hurricanes and ongoing wildfires to conduct disaster relief communications. ARRL asserts that the higher data rates offered by PACTOR 3 and PACTOR 4 emissions are critical to sending relief communications. We conclude that granting the requested waiver is in the public interest.” The waiver is limited to 60 days and applies only to stations in the continental US and Puerto Rico using PACTOR 3 and PACTOR 4 emissions and who are directly involved with HF hurricane and wildfire relief communications.

Hello everyone!

Thank you so much for making the Elmer Net the place to ask questions and get answers! Having been a licensed “Ham” since 1958, have seen a lot of great new things over the years and am thrilled with everything new (although I’m not that keen on using the internet for contacts other than IRLP Repeater linking.. Hi).

Just wanted to let you know, we are on the 1st and 3rd Wednesdays each month. October Nets will be on the: 7th and the 21st. Promise to mark my own calendar too!

[NVIS] 5-MHz Interoperability Channels Designated for Wildfires and Hurricane Sally Response

5-MHz Interoperability Channels Designated for Wildfires and Hurricane Sally Response

09/15/2020

The Federal Emergency Management Agency (FEMA) has announced that two 60-meter channels have been made available, as necessary, for interoperability between US Government stations and US amateur radio stations involved in emergency communications related to the wildland firefighting response in California, Oregon, and Washington, and to Hurricane Sally. These interoperability channels will remain active until the need for these channels no longer exists:

  • Channel 1 — primary voice traffic 5332 kHz channel center, 5330.5 kHz USB voice

  • Channel 2 — digital traffic 5348 kHz channel center, 5346.5 kHz USB with 1.5-kHz offset to center of digital waveform.

Frequencies may be modified or added to by FEMA Region 10 for their area or operations due to existing 5-MHz/60-meter interoperability plans for their region.

Amateur radio is secondary on the 5-MHz band and should yield to operational traffic related to wildland firefighting and hurricane response. Although the intended use for these channels is interoperability between federal government stations and licensed US amateur radio stations, federal government stations are primary users and amateurs are secondary users.

The Military Auxiliary Radio System (MARS) is following FEMA’s lead on the interoperability channel designations for the wildfire and hurricane response. Army MARS Program Manager Paul English, WD8DBY, says he has alerted all MARS members of the FEMA channel designations and MARS members are prepared to support response efforts as needed.    


Interesting article about the new repeater on ISS #satellites

This article made it to the front page of y-combinator news today. It's interesting how often ham radio topics make it to that site.

Looks like they had to do quite a few modifications to get the rig flight qualified.
