Leave your Internet out of my Amateur Radio

I don’t understand the use of the Internet in conjunction with Amateur Radio.  Echolink, Winlink 2000, and IRLP all setup a false sense of security for users.  Creating a dependency on something you cannot control means that resource won’t be there when you need it.  Most recently the American Radio Relay League (ARRL) has been advocating the use of Winlink 2000 for emergency use without much forethought, in my opinion.  This really isn’t much surprise since they’ve started doing away with bulletins that could easily be made available over digital amateur radio networks in favor of shiny, flashy, and pretty text that are best viewed using a broadband Internet connection.

  1. If I have Internet access why do I need amateur radio?  It’s actually a really good question.  The ARRL likes to think that ARES members march into a disaster-affected area or into emergency operations centers and setup shop to save the day when traditional communication systems fail.  But if these ARES members only know how to use Internet-based communication systems then they very well might fail as well.  There is a lot of talk of using Winlink 2000 for ARES because email is easiest for our “customers” to handle at the distant end.  Okay, I’m good with that except if the customer doesn’t have Internet access then you are sending messages that won’t be delivered in a timely manner (maybe not until days or weeks after the disaster).  But if their Internet access is working then why do I need amateur radio operators?  Simply put, I don’t.  During Hurricane Irene, the EOC I was stationed at never lost communications with the world or the local shelter.  Had they, we were prepared to handle traffic to the state EOC digitally through the Virginia Digital Emergency Network (VDEN) which does not rely on any Internet connectivity.
  2. If I train to use the Internet I won’t train to use anything else.  It’s a sad fact but when people rely on a technology they deem to be superior because it’s fast or easy you then they end up failing to maintain skills that would allow them a means of communicating around a failure.  The same goes for the equipment being used.  Think that local Echolink repeater link is going to be available during an emergency?  What if it’s not?  If you practice and use that path to communicate with, say, the National Hurricane Center will you be able to do so over HF when your Echolink no longer functions?  Do you even remember the frequency they monitor (14.325MHz)?  Does your equipment even work?
  3. Why would I want to use the Internet to communicate to other Amateurs?  Good question.  I received a license from the FCC stating I have access to all kinds of frequencies in which to exploit using all kinds of modes of communication.  Why would I want to connect an Internet link to the system?  Heck, if I did that I might as well turn the radios off and use the fiber connection I have plugged into my house for all my global communications.  Funny, though, that back in 2003 the SouthEastern Repeater Association (SERA) met and agreed that two hams communicating over the Internet with no RF was still “ham radio”.  In an emergency this would fall squarely into #1 on this list.  The ARRL’s National Traffic System (NTS) currently handles messages going between hams, between hams and non-hams, and even between non-hams and non-hams using amateur radio without Internet links.  They do this using voice, CW, RTTY, and a 24/7/365 digital network, the NTSD, that links up the entire country.  If deployed properly, the NTSD could bring doorstep-to-doorstep communications between hams anywhere in the country (US and Canada) without much delay.
  4. Degradation of skills.  I know of some very smart hams that build and maintain digital networks.  These are smart individuals and they maintain their equipment much as they do their minds by testing different scenarios, working through routing problems, and figuring out how to provide connectivity to different geographic areas when none exists.  Then I know of people who are just smart enough to connect a radio, TNC, and computer together, get the Winlink 2000 software going, and think that the VHF or UHF link they have just created to the Internet is how they are going to communicate with the state EOC a hundred or so miles away.  If the Internet fails at either location or somewhere in between they won’t know how to quickly work around the problem because they don’t have the skills or the equipment to do so.

With so many modes and bands in which to operate why do so many hams seem to revolve around the Internet?  Why has our ambassador, the ARRL, spent more time getting information into a pretty format rather than supporting the means of moving information around via ham radio?  I dare say there isn’t anything that can be done on the Internet that can’t be done on Amateur Radio with respect to communications.

SKCC WES

I received my SKCC WES Participation Certificate today; very cool.  I’ve been a member of the Straight Key Century Club (SKCC) for almost a year and had never participated in their Weekend Sprint (WES) which takes place every month for twenty-four hours.  I scored 115th out of the 199 entries.  Not bad for arm chair operating off and on.  I think I mustered sixteen contacts including Australia, Alaska, and France among the other stateside contacts.  It is a fun event and I hope to participate in the next one which come up on 11 December 2011.

HamQTH.com

Recently the owners of QRZ.com Callsign Database started restricting access to addresses and other data unless you were a registered user. If you used a logging program, such as CQRLOG, you would have to pay a yearly fee to access this mostly public information. I’d much rather give a donation to a group that is trying to do the right thing rather than have my information held hostage for ransom. Because of this I’d like to introduce HamQTH.

HamQTH is a free ham radio callsign database that provides similar information but is completely free.  The owner of the data (you) gets to determine what is visible and what isn’t.

I encourage everyone to visit HamQTH and try it out.  I already use it for my logging program and have received great results so far.  And best of all it’s all free!

Temporary TCC Lima/Victor

A while back I had told Marcia KW1U that I’d like to try a TCC slot one day to see what it’s all about.  Yesterday was that day.  The Lima schedule goes from the second cycle of the Eastern Area Net (EAN) to the Central Area Net (CAN) and the Victor schedule comes back from CAN with any traffic heading east.  When I checked into EAN as the Central Receive (with two through) I was told that I had a station with two messages for Central.  This is going to be easy I thought.  I can surely take four messages over to another net.  What I wasn’t ready for, though, was the nearly twenty messages I received from CAN to bring back!  I had a lot of fun, though, and while I couldn’t hear 1RN or 2RN nets when I listened for them I was able to deliver all my traffic, mostly going to Massachusetts and Ontario, over the NTSD.

I had a lot of fun and can hardly wait to do it again.  If you are an amateur radio operator in the United States or Canada I’d recommend getting involved in NTS especially at the local/section level.

Brass Pounder’s League – so close…

About half way through the month of October I realized that I might have a chance to hit the five hundred message mark to qualify for the ARRL’s Brass Pounder’s League.  As the liaison from Virginia to 4RN and sometimes from 4RN to EAN I have the potential to move some traffic.  Add in my NTSD station and we’re talking message central here.  And since new ra-day started a few hours ago here’s how I faired:

O/59
R/206
S/217
D/6
T/488

For those that don’t know O stands for messages originated, R stands for messages received, S stands for messages sent, and D stands for messages delivered.  T is just the total of all messages handled.  Unfortunately I was twelve messages short of the required 500.

I’m a little disappointed that I didn’t make the 500 message mark but 488 is a lot of messages!  And I’m not giving up, either.  I effectively have this entire month to try to do it all over again!  Hopefully I’ll have more trips to EAN with more traffic and hopefully band conditions will improve from my station to the rest of fourth region (VA to FL).

CW Opportunties for Fun

I friend of mine recently tested for the Technician-class Amateur Radio license and passed without trouble.  Not that this is surprising given his history in the communications world (fricken helium atom, Sir).  What I find neat is his style of operating as a newly licensed ham.  I remember when I received my Technician license all I wanted to do was talk on the local repeaters and meet people that were around town.  This guy I *think* owns an HT but has been sucked down to the bowls of 40 meters ever since receiving his ticket.  The Novice portion of the band never looked better to him.

Unfortunately I haven’t been able to meet him up on the air.  It’s not for him trying, however.  He noted in a recent message that he is QRV beginning when he walks in the door from work and then again for a couple of hours starting at 8PM.  I, on the other hand, am usually pulling myself out of the office/radio room during those times.  I do plan, however, to make a sched for later this week.

In the mean time I thought I’d send him a couple of resources that he might find useful.  And if he might find it useful then I’m sure others might as well so I’ll just post here.

Clubs and Organizations

  • Straight Key Century Club – When I met W8DEA on the radio back in December of 2010 he pointed me to this group.  Free to join and participate, this club encourages folks to get on the air and have fun (using a straight or other manually operated key).  I highly recommend not only joining the group but participating with the group.
  • The International Morse Preservation Society – Also known as FISTS is one of the older groups of Morse enthusiasts that have a presence around the world.  Similar to SKCC, they have contests and other activities getting people on the air using their skills.

Local Nets

  • Carolinas Slow Net – Meeting every night at 8PM (ET) on 3571 kHz, this net is great for those just getting into CW and needing a little help finding their feet.  This net is also a NTS-affiliated net and traffic is passed.
  • Carolinas Net – Early – Meeting every night at 7PM (ET) on 3573 kHz, this net facilitates traffic flowing from North Carolina and South Carolina to the 4RN net.  This net is advertised as running 20 to 22 WPM.
  • Carolinas Net – Late – This net is a partner to the Carolinas Net – Early.  The Late net meets to distribute traffic coming from the EAN and 4RN nets.  The Late net meets at 10PM (ET) on 3573 kHz.
  • Virginia Net Early (VNE) – This net meets at 7PM (ET) on 3578.5 kHz to pass traffic throughout Virginia and to the 4RN net.

Other neat stuff

  • Maritime Radio Historical Society – I’d be holding back if I didn’t give some credit to one of the groups that really spurred me on to working on my fist.  The guys (and gals) at KPH/KSM/K6KPH really know how to excite the atmosphere and my receiver.

This is a short list of items I’d pass to a new ham who is hot on the key.  I, for one, will be guarding 7114kHz when I’m in the shack and not on a net working traffic.  Remember to throw your callsign out every so often so that others will know you are there.  If anyone knows of any other good resources please leave a comment and I may just include them.

Automatically Controlled Digital Stations on HF

According to Part 97 of the FCC rules (specifically §97.221 Automatically controlled digital station) automatically controlled digital stations have 134.5kHz of space to work in on the the HF bands (10 meters through 80 meters).  Breaking this bandwidth up into 500 Hz channels* we see that we have 269 spaces for digital stations to work.  The breakdown is as follows:

Frequency               | Bandwidth | Channels
------------------------|-----------|-------------
28.120 MHz - 28.189 MHz | 69 kHz    | 138 channels (57 channels @ 1200 baud)
24.925 MHz - 24.930 MHz | 5 kHz     | 10 channels
21.090 MHz - 21.100 MHz | 10 kHz    | 20 channels
18.105 MHz - 18.110 MHz | 5 kHz     | 10 channels
14.095 MHz - 14.0995 MHz| 4.5 kHz   | 9 channels
14.1005 MHz - 14.112 MHz| 11 kHz    | 21 channels
10.140 MHz - 10.150 MHz | 10 kHz    | 20 channels
7.100 MHz - 7.105 MHz   | 5 kHz     | 10 channels
3.585 MHz - 3.600 MHz   | 15 kHz    | 30 channels

So we can easily see where we have the most areas to play.  Ten meters may be a bit misleading as you can run 1200 baud packet there.  So who is operating on all these frequencies?  Looking backwards (longest wavelength first) we see the following channel users:

3.5850 MHz - WL2K
3.5859 MHz - NTSD

14.1027 MHz - WL2K
...
14.1042 MHz - WL2K
...
14.1067 MHz - WL2K
...
14.1080 MHz - WL2K
14.1085 MHz - WL2K
14.1089 MHz - WL2K
...
14.1099 MHz - WL2K
14.1100 MHz - WL2K
...
14.1120 MHz - WL2K
...
18.1062 MHz - WL2K
18.1069 MHz - WL2K
...
21.0934 MHz - NTSD
21.0987 MHz - WL2K
(All frequencies are center.  WL2K and NTSD station frequency list pulled on 19 October 2011.  Incomplete listing of US Packet SKIPNETs.  Only US stations included in the listing.)

So are we using our frequencies in a channelized fashion?  No we are not.  What does that mean?  That means that the overall efficiency of our spectrum is reduced.  If you have a station between two channels transmitting they are basically occupying two channels instead of one.  Is this a problem?  Maybe.  I’ve heard several times two stations transmitting where they were clearly overlapping causing neither station to communicate with who they were attempting to talk with.  But from where I’m listening  (40 meters) it’s rare.  The use of PACTOR-III makes things worse, however, as these stations transmit 2kHz-wide signals taking up four channels.  These stations also get on and off the frequencies faster as well so they aren’t taking up any channels as long as a regular 500 Hz station would.  (Yes, we are TDMA.)  You can tell by the ellipses I’ve included in the chart where there are gaps in known usage.  That means that there is still room for new stations to come up on HF and utilize the spectrum.

Would it be better to have a “frequency coordinator” of sorts working with all HF networks to spread stations out and make better use of the spectrum we have?  Probably wouldn’t hurt.  Is it necessary?  Probably not; at least not now.

And remember that band that has 69kHz of available spectrum?  No one claims to be there…

* There is nothing that says we have to channelize our spectrum here but to not do so would be incredibly wasteful and could lead to interference.
