With all commentary periods for the FCC's 'Notice of Proposed Rulemaking' (Docket 15-99) now closed, it appears that one of the last comments to be filed may contain the most powerful arguments in favor of swift implementation.

In its extremely detailed 42-paged submission, the ARRL states, in no uncertain terms, the reasons why access to both the 2200m LF band and the 630m MF band should not be held back and that service rules should be 'finalized'. Indeed the powerful arguments stated in favor of implementation should go a long way in making this happen sooner rather than later.

The FCC's position is that there is little to no evidence to indicate that amateur radio operation on either band would be incompatible with power company PLC systems, going as far as stating that at distances of 1km or more from PLC lines, "there is no chance of interference". Further supporting their claim, the thousands of hours of experimental operation were offered as powerful proof and that the ARRL was “unaware of any reports of interference to PLC systems arising from that operation conducted pursuant to numerous Part 5 experimental licenses…in the large band utilized by PLCs.”

In addition, the ARRL had harsh words regarding the FCC's attempt to legitimize the growing number of fish-net beacons in the 160m band, and pulled no punches regarding their position in this matter.

"There is no indication that these buoys are compatible with other uses in the band, no track record of interference avoidance or resolution, and certainly no indication that the current operators can be relied on for compliance with the Commission’s rules."

"The Commission is urged to avoid enacting rules that it has no effective ability or intention to enforce. That fishing vessels have, with impunity, illegally deployed radio buoys in this band on a widespread basis (whether or not due to misrepresentations of the importers and retailers of these devices or due to a disregard of the Commission’s rules generally) without even nominal enforcement actions by the Commission, provides no basis for assuming that there will be compliance with any deployment limitations (including geographic deployment restrictions) on these buoys going forward. Nor is there any basis for the assumption that there will be any enforcement action taken with respect to continued illegal operation of the buoys if and when interference is caused. Spectrum planning by the Commission in this context has to be based on ex ante determinations of compatibility rather than mere assumptions, especially where the record indicates such a low level of historical compliance."

A summary of the comments can be read here in the ARRL News while all comments filed for the NPRM be found here temporarily, while the FCC site is down for maintenance.

SCRIPT

AUDIO

Listening to podcasts has been part of my daily habit for almost a decade. I lean heavily towards audio podcasts (as opposed to video), so I can listen to them while driving. My smartphone is always loaded with hours of content on a variety of topics which is especially useful for international flights.

Podcasts come and go (or podfade) and recently I’ve noticed a few new ham radio podcasts. Well, they might not be all that new…perhaps I just woke up and noticed them. Anyway, I am passing them along in case you have not come across them.

The QSO Today Podcast by Eric 4Z1UG:

QSO Today is a weekly conversation between me,  Eric Guth, 4Z1UG, and my amateur radio operator guest. Each guest tells his or her’s ham radio story to the present time.  I select guests based on their contributions to the hobby through their publishing of articles and books on ham radio, their involvement in the creation of new technologies that enhance the hobby, and the role that they played to bring the amateur radio to others.

The Fo Time – The Other Ham Radio Podcast by Cale K4CDN:

It’s a new Podcast for the Up and Coming Amateur Radio Operator aka Ham Radio Operator. Whether you’re looking for the latest news, a different take on an idea, or just some good humor, Fo Time is the Podcast for you.

If you aren’t sure about the name, this might help.

The 100 Watts and a Wire by Christian KØSTH:

Created by Christian Cudnik, KØSTH in 2015, 100 Watts and a Wire is a program celebrating amateur radio through the eyes of a new ham. The show features topical conversation and interviews, news and an entertaining look at the adventures of a ham trying to figure it all out.

I’ve found all three of these podcasts to be well done and interesting. They all typically run about an hour long. Frankly, that’s a bit much for me, mostly because it does not fit my commute time. Not bad for an airplane ride, but too long for driving to work. More importantly, my smartphone is overflowing with interesting audio content, so I have to be selective.

Other Podcasts

I’ll mention a few other podcasts that deserve attention: The Ham Nation podcast has set a new standard for ham radio video podcasts. Hats off to Bob Heil and crew for their efforts. The Amateur Radio Newsline got its start by delivering audio programs via telephone for hams to play on their local repeater. Many repeaters still play their program but I get their feed via my smartphone. They continue to do an excellent job of stuffing interesting content into a 20-minute format. While not a ham radio podcast, This Week in Tech from TWiT remains a quality source of tech news and opinion (lots of opinion).

Give these podcasts a listen and let me know what you think.

This year at the RSGB convention we will be running a buildathon based upon the same format of the other successful build events in the past – this is an excellent time to attract a new audience to our events.

This year however we are using a new kit. The Acorn II kit developed by Kanga Products and M0XPD, is a Software Defined Radio kit that runs on the SSB portion of 40m. But the kit can also be configured to run on any HF band – assuming you have a Band pass filter & a suitable Local Oscillator. The kit has been developed to allow you to pipe in an external Local Oscillator and allow you to connect Band pass filters for other HF bands.

The kit was developed to run with the M0XPD Si5351A Arduino shield, which allows you to use the Arduino as a VFO. And can plug straight into the radio as a local oscillator

Using just a stereo line in on a sound card, and some widely available SDR software (Such as HDSDR), you can get great results from little financial outlay. It is indeed a great introduction into SDR.

I built one of the prototypes here is a video of the build. I will cover configuration & set up in a forthcoming video – perhaps when I have access to a good 40m antenna

Yesterday's mail brought an official - looking envelope from the U.S. Army! It contained a very nice letter from Fort Huachuca, Arizona, thanking me for participating in the '66th Military-Amateur Crossband Test' as well as three QSL's for the Army-affiliated contacts that I had made back in May.


During the activity, I was able to work Army stations AAZ (AZ), WAR (Pentagon), WUG-2 (TN) ... all on 20m via the crossband mode as the military stations transmitted outside of the band.





In addition to these three, two Navy stations were worked ... NWVC (IN) and NPD (TN) but it appears that 'Army' has beaten 'Navy' ... at least when it comes to QSL'ing!

It was this time of year, from August 28th to September 2nd, 1859 that the Earth experienced what was to be known as The Carrington Event. On September 1st, a solar flare was observed by two British amateur astronomers, Richard Carrington and Richard Hodgson.


This was a coronal mass ejection that occurred during Cycle 10. It was a solar storm of such great intensity that reportedly, people as far south in Florida and Cuba were able to see aurora. In the Rockies, gold miners woke up in the middle of the night and started preparing breakfast because they thought it was daybreak. The aurora was so bright here in the northeast, that people outside were able to read newspapers by the aurora's glow.

Telegraph stations (our forerunners) were hit particularly hard. It was reported that some telegraph poles threw sparks into the air. Telegraph operators reported that not only did they receive shocks when they tried to operate, but that they were also able to continue to operate their telegraph apparatus after disconnecting it from the power supply.

I can only imagine the damage that would occur today if we suffered a direct blast from the sun as we did in 1859. I'm pretty sure that not only would the power grid be very badly affected, but that telephone and radio communications of all types would probably be non-existent, and much, much more.
