Things had been pretty quiet on the ham front lately but then I ran into a string of “That’s Not Real Ham Radio” discussions. This happens from time to time…I usually ignore it…but this time I got sucked into the topic.

It started with some HF enthusiasts I know talking about how “digital modes” are just not very satisfying. Their point is that with CW and SSB, there is an audio connection to your ear that makes you an integral part of the radio communication. The extreme-DSP modes such as JT65 insert serious signal processing that essentially removes the human connection.  This can quickly lead to the generalization that these digital modes “aren’t real ham radio.”

I think its fair to say that most hams think of the HF bands as the center of the hobby…getting on the air, bouncing signals off the ionosphere to talk to someone over the horizon. Some hams will go even further and say that CW is the only way to go. Anything less is just phone. FM and repeaters? Forget that stuff…not enough skill required. And certainly, don’t get stuck on 2 meters.

In a previous post, I argued we should not confuse religion with modulation. I do occasionally make snarky comments about the continued use of AM (AKA Ancient Modulation), but I’ve tried to tone that down in recent years.

What About DMR?

Just last week, I was playing around with a DMR hotspot on the Brandmeister network. It really struck me that people on the system were having a blast talking to each other across North America and around the world. But then that nagging little voice in the back of my head said “hey, wait a minute…this is not real DX…the RF signal might only be traveling 20 feet or so from an HT to a hotspot.”

This caused me to put out a plea for insight on twitter:

I received a lot of good replies with the answers tending to clump into these three categories:

• I don’t know (“That’s Not Real Ham Radio”)
• It’s fun, new technology
• It’s a digital network that brings ham radio operators together

My interest seems to fall into the second category: this is fun, new technology. Which does make me wonder how long this new technology will remain interesting to me. Well, that is difficult to predict but I’ll invoke the principle of try not to overthink it. The idea that DMR is a digital network that brings ham radio operators together makes some sense. In the past, I have argued that amateur radio is not for talking. In other words, if you just want to talk someone, there are much more convenient ways of doing that. Still, there is something attractive about this ham-radio-only digital network.

It really is important to not overthink this kind of stuff. Ham radio is supposed to be fun, so if you are having fun, you are probably doing it right. If you are not having fun, then you might want to examine what you are doing. See my post on the Universal Purpose of Amateur Radio.

Sometimes hams can get a little spun up about those other guys that don’t appreciate our way of doing ham radio. What the heck is wrong with them anyway? I’ve always been inspired by the Noise Blankers Mission Statement:

Do radio stuff.
Have fun doing it.
Show people just how fun it is.

If your preferred form of ham radio is so superior, it ought to be easy to show other hams how cool it is. If not, then maybe you aren’t doing it right. Conversely, as long as other hams are having fun and operating legally, don’t knock what they are doing. In fact, encourage them. We need more people having fun with ham radio, even if it’s not your favorite kind of fun.

That’s my opinion. What do you think?

My Moonrise

This week I had several days of unobstructed ocean moonrises as the Moon peaked on its monthly northern declination track. Thanks to the recent topping of my next door neighbour's large Douglas Fir, and removal of low-hanging branches, I am now able to track moonrises a little further to the south than before and can add two more EME days that were previously blocked by the large tree. All operations are on 2m JT65B mode, using a 9el Yagi and 140W output.




When I started (April 1) conditions looked as if they should be good, with lunar perigee (Moon's closest approach), degradation (background skynoise) and declination all looking favorable, but I was in for a surprise.

The rising yellow plot indicates the Earth-Moon distance growing further apart (increasing path losses) while the red plot indicates fluctuation in daily skynoise (temperature) near the moon. The blue plot indicates declination track from north to south ... for me, the higher the better.

Listening on the first two days (April 1-2) produced a few weak signals from the larger stations only and nothing from the more common '4-Yagi' stations and, no QSO's ... something was amiss. I can only attribute this to some real-time solar flaring during this two-day period and the resultant short term geomagnetic agitation the flares produced ... but almost as if the 'switch' had been flipped, the third day proved to be much different.

On day three, five new 'initials' were worked including one new state (New York) and two new DXCC countries! Truly surprising was that two of the stations worked were using just two Yagis, with both stations answering one of my 'CQ's.

Good conditions continued for the next few days, bringing my initials count from #87 to # 95, with the following stations all going into the log, turning a disappointing start into one of the best lunar sessions I have encountered:

HA6NQ, LZ2FO (two 13 el Yagis), EB5EEO, K2ZJ (two 14 el Yagis), DK5YA, S52LM, F8DO, PA5Y, SV6KRW, UA3PTW, OK1UGA.

April's operation brought  my 2m DXCC count to 29 and states worked total to 27.

SV6KRW's 4 x 8el Array

EB5EEO's 4 x 32el Cross-polarized Array (16V / 16H)

DK5YA's 4 x 22 Cross-polarized Array (11V / 11H)

As mentioned in my last EME report, I keep wondering when I will run out of stations that are able to hear my small station, forcing me to build a bigger amplifier for a few more precious db, but with the ability to occasionally work some 2-Yagi stations, the list of potential targets has increased dramatically ... perhaps the large Fir tree was a bigger attenuator than I had thought.

The FCC issued Report and Order 17-33 which creates two new bands for amateur radio, 472-479 kHz (630 meters) and 135.7-137.8 kHz (2,200 meters).  As ARRL reported, it is a “big win” for amateur radio.  I’ve been waiting in anticipation for the 630 meter band as it’s an old yet new frontier for us.  With old Sol taking a bit of a nap for the past few years and perhaps for years or decades to come, lower frequencies are where we’re going to have to play for more fun.

There are a few caveats in using these bands.  The FCC is requiring radio amateurs be at least 1 km from electric power transmission lines using Power Line Carrier (PLC) systems on those bands.  PLC is a technology that uses low frequency signals on power lines to perform signaling and control functions, and often meter reading.  Amateurs will have to notify the Utilities Technology Council (UTC) of station location prior to operating on 630 and 2200 meters.  The UTC maintains an industry database for PLC operations.

Those who were around to experience the Broadband over Powerline (BPL) brouhaha around 2003 to 2005 may recall the UTC organization.  At the time BPL was billed by proponents as the next big thing in broadband Internet.  Amateur radio operators and ARRL argued vigorously against BPL, citing engineering and evidence that the HF signals on the power lines radiated into the ether and interfered with HF radio operations.  The FCC turned a blind eye to the issue.  Luckily market forces took out BPL as a viable broadband solution due to increasing bandwidth needs and numerous failed trials which uncovered its technical difficulties and business problems.  PLC and BPL are cousins, with PLC operating below 500 khz and HF BPL operating from 1.8 to 30 Mhz.

The UTC, several electric utilities, and a handful of BPL equipment vendors at the time claimed that BPL didn’t interfere with HF radio operations.  The explanations and claims baffled those of us experienced in wireless and RF engineering as it’s a fact that an unshielded conductor tens of wavelengths long, conducting RF signals, will radiate energy.  The math and science supported this and measurements in the field provided real life evidence.

The UTC notes the following about PLC operation:

“This Activity is established as provided for in the FCC Rules and Regulations, Part 90.35(g) (47 C.F.R. ‘ 90.35(g)) relative to PLC operation in the 10-490 kHz band, and the NTIA Manual of Regulations and Procedures for Federal Radio Frequency Management, in Part 8.3, under the heading “Notifications in the Band 10-490 kHz,” (see 47 C.F.R., Chapter III). Electric utilities are allowed to use power line carrier (PLC) transmitters and receivers for control signals and information transmission in the 10-490 kHz band without obtaining a license from the [FCC]. However, PLC users are not protected from interference from licensed radio transmitters.”

Part 90.35(g) states that PLC operates under Part 15.  With the distance separation and notification requirement for amateurs, the FCC has granted an unlicensed incidental radiating non-wireless service protection from a licensed wireless service.  This was essentially the case with BPL in the early 2000s with an unworkable process for resolving interference issues, and interference complaints from amateurs living in trial site areas languishing for months with no action.

With this latest frequency allocation to amateur radio and requirements for protecting PLC operations, the tables are turned.  It’s the electric utility industry, that once claimed power lines wouldn’t interact with wireless spectrum, that could potentially experience interference.  Undoubtedly many FCC staffers involved in BPL in the past are no longer at the agency and the electric utility industry has forgotten about the BPL fiasco and fail to realize the irony of needing to protect PLC from wireless.

All this being said, I’m not attempting to downplay or criticize the allocation of the two new bands.  I think it’s wonderful and I applaud ARRL’s success.  However, I hope amateurs wishing to enjoy these bands aren’t prevented in doing so.  While it’s unlikely a large number of amateurs will be excluded from operating due to PLC on high voltage transmission lines, PLC systems are used in meter reading applications in neighborhood power distribution systems.  Hopefully the majority of systems do not operate in the new 630 and 2200 meter amateur bands and we can peacefully coexist, unlike what occurred with BPL.
