Despite this oft repeated myth, CW is RARELY ever used in emergency
communications. I talked to a number of different hams in So Cal whose ham radio involvement is virtually all emergency services ops and NONE of them ever hear CW used. I mentioned that on QRP-L and only one person (John WB8RCR) could come up with a situation where CW is regularly used. He is in Upper Michigan and, I don't remember the details, but it had to do with their high latitude and auroral effects. Otherwise, no one there could come up with a single emergency services group using CW ops for any purpose. Certainly, there are isolated cases where CW has been used as a last resort for particular communications, but then there are cases of trapped individuals tapping out pleas for help with a rock. There are many interesting and useful applications for CW and it has been virtually my only mode of operation for 48 years, but to continue to tout it as necessary for emergency preparedness is to deny reality. I would be willing to bet during the worst moments of the current crisis in the Gulf states that nobody was heard to utter the words, "If only we could get some CW ops in there with battery power rigs." It just doesn't happen. I dare say there will be no stories of CW saving the day for anyone. Most emergency services ops are handled on VHF/UHF FM. Far less is handle via HF SSB. Consider that amateur radio emergency services must interface with other services whose operators don't use CW and you can see it just isn't very useful for emergency communications in the real world.

It just doesn't happen.

Health and welfare traffic can be independent of other services. And why can't the interface consist of a ham handing a piece of paper to his other-service counterpart? Having handled traffic by CW in the dark ages (somewhere I have a BPL medallion) I can tell you that phone cannot come close to the efficiency or accuracy of CW in handling formal traffic. And there is, or should be, a structure that already exists for them to fit into -- the ARRL NTS -- which would provide connections to these operators. Frequencies, schedules, liasons, all should exist. The problem is not that CW wouldn't be useful, it's that there aren't enough competent CW operators who know how to handle traffic.

I was monitoring the emergency net on 80 meters the other day when a
group of old boys started up their regular net about 2k down and started bleeding all over the e. net. I went down to see who they were and tuned in just in time to hear some guy from the e. net break in and ask them to move down a couple of more k as they were causing interference. The old boys were pretty indignant at first, explaining how they always used this frequency and how there was another net about 4k up. "Why did you pick such busy place" he said, "Never heard of such a thing" said another, "but we'll move down". I thought they were pretty nice guys, giving up their regular slot and all. They sure had no idea of the emergency net though.

As we all know, there is traffic on 14.265 with occassional inactivity (inactivity is good). I too, am surprised with the success of using phone. Satern uses phone and their protocols require use of phonetics when in doubt. They also require use of "pro-words" during traffic handling which works very well. Sometimes during an exchange, one can become emotional and the need to be clear is important. That is maybe why CNN was repeated phonetically. Protocol rules, do not "assume". The use of digital modes may work well, but you still need phone to originate the data. I find the very basics of ham radio always comes through when disaster strikes.

Come on, Vic. Where is a CW operator going to set up? Are they going to set
up some place like the Superdome with all that pandemonium? Are they going to walk around operating HF with 10' poles sticking out of their back pocket like W0RW/PM? It just doesn't make sense when a ham on foot with a pocket sized HT on VHF communicating through a repeater or an on site dual band VHF/UHF mobile rig acting as a repeater can move fast, stay safe and get the message through using clear, clean FM. It's done all the time all over the country. Hams were not allowed in early-on because the situation on the ground was just not safe even for rescue personnel. Angry people, violence, shoot-outs. How's an HF CW guy going to deal with that? They weren't jumping out of helicopters with HF CW rigs. They are going in with VHF/UHF HTs to communicate with local emergency services and getting some H&W traffic out via VHF/UHF. It is then put on HF by guys sitting at home with big antennas and lots of power or the Internet. I live a few miles from the San Andreas Fault. I have a K1, K2 and KX1 all able to work on battery power for extended periods. But when the Big One hits and I need help, I'm grabbing my FT-470 HT first.

I went to the Satern web site to read about past emergencies that they were
involved in. I was surprised at the level of traffic. In most emergencies they were only handling a few hundred messages. I bring this up certainly not to minimize the importance of these messages to those involved, but to point out that voice is well suited to this volume of traffic, and there does not seem to be any real need for building high speed digital links on HF. I worked full-time at K2USA handling CW, SSB and even some AM traffic on ham nets and MARS nets. Even then (we opened the station to handle AK Earthquake traffic in 1964), throughput on SSB was comparable to that on CW when the operators at both ends were skilled. I have no doubt that there are isolated instances when CW is the only mode to get through, but for the bulk of "first responder" traffic and Health & Welfare traffic, VHF/UHF FM is a far better choice.

In reply to this post by crmabbott
It is my understanding from a communication with WB8RCR, a member of the
Michigan Net, that CW is used because of a geographical anomaly in Upper Michigan. Because of the high latitude and presence of aurora in Winter, CW makes a regional net more reliable. It is the only instance I was able to turn up where emergency services personnel preferred CW over voice. The NREN you cited is sponsored by the same Michigan Net. Traffic volume is modest at best. The fact remains. HF CW is just not necessary or desirable in the vast majority of emergency communications. The military, including MARS, has abandoned it. There are no government agencies that I know in the US and maybe the world, that depend on CW for anything. That does not mean CW is useless. More and more hams are discovering that it gets a brief canned exchange across during contests and DXing. But that's a far cry from handling traffic from a flooded New Orleans or ground zero at the WTC. Things have changed, yet we promote the same myth that CW can save the day. Apparently, those who do this kind of work day after day, don't agree with you.

OK, guys, get ready to hate me. Here in Alaska, (that's a bit North of Michigan, to our flatlander friends) - Aurora is the norm. As in - every day, 365 days a year. Some days it's no big deal, some days it eats your lunch, it's just a fact of life. As often as not, SSB will get through when CW won't. FACT - not a typo! Apparently, with rapid changes in path length, which is what is responsible for the waterey sound of classic aurora reflection propagation, CW signals sometimes get lost in the process. I think this might be because CW signals are on just one frequency, and the destructive effects of multipath (selective fading) can wipe out individual dits or dahs, making copy of CW problematic. SSB, on the other hand, occupies a comparatively wide channel, and has energy on any number of frequencies within that channel. So, during times when aurora is very active, SSB apparently gets through because it has a sort of built in frequency diversity. If a hole gets punched in a SSB signal at one spot, there are still hundreds of adjacent frequencies that have an equal chance of being reinforced. The net result is that SSB suffers from rapid shifts in tonal balance as the "notched out" frequencies shift rapidly within the SSB pass band, but enough energy still remains that copy is possible.

Why hate anyone, that is why a communicator needs to be versed in all the
tools. That would be SSB, digital, CW, etc... You are forced, since emergancies are not scheduled to take what ever mode works the best at the specific time and get the information applied in a standard format through..... 73 Chuck AA8VS ----- Original Message ----- From: "Jim Wiley" <[hidden email]> Cc: <[hidden email]> Sent: Monday, September 05, 2005 2:42 PM Subject: Re: [Elecraft] Dropping the Code Test > > OK, guys, get ready to hate me. > > Here in Alaska, (that's a bit North of Michigan, to our flatlander > friends) - Aurora is the norm.

So much for the rationale for the ONLY CW emergency net I could come up
with. Hi. I suspect the REAL reason it is used is because it has been around since 1935 and it is an UP Michigan tradition, but I don't know that. I just relayed the rationale that John gave me. Another point that is missed is that emergency traffic is not just endless numbered messages relayed verbatim. A lot of it is emergency coordination where emergency services personnel are trying to get information out of an area or handle logistics that are not in the form of formal messages. This is often much easier on voice than on CW where decisionmakers can hear what is going on and relay instructions to the operator without formal messages passing back and forth. It might help us to preserve ham radio in the future if we learn to let go of the myths, and determine what we can contribute in the real world. We look foolish when we can't justify our cherished traditions to hard-nosed regulators. Me? I use CW all the time, not because it's better, but because it's fun. Sometimes that's justification enough.

Here in Alaska, (that's a bit North of Michigan, to our flatlander friends) - Aurora is the norm. As in - every day, 365 days a year. Some days it's no big deal, some days it eats your lunch, it's just a fact of life. As often as not, SSB will get through when CW won't. FACT - not a typo! Apparently, with rapid changes in path length, which is what is responsible for the waterey sound of classic aurora reflection propagation, CW signals sometimes get lost in the process. I think this might be because CW signals are on just one frequency, and the destructive effects of multipath (selective fading) can wipe out individual dits or dahs, making copy of CW problematic. SSB, on the other hand, occupies a comparatively wide channel, and has energy on any number of frequencies within that channel. So, during times when aurora is very active, SSB apparently gets through because it has a sort of built in frequency diversity. If a hole gets punched in a SSB signal at one spot, there are still hundreds of adjacent frequencies that have an equal chance of being reinforced. The net result is that SSB suffers from rapid shifts in tonal balance as the "notched out" frequencies shift rapidly within the SSB pass band, but enough energy still remains that copy is possible.

It is slightly lower priority than emergency traffic, but it is very high volume. The police, etc., have their own communications systems and don't need ham help. There are plenty of applications for CW in an emergency. The overriding reason that CW is not used anymore in emergencies is simply that there are too few qualified operators. Someone who can copy 15 wpm in his head, or even recognize his own call in a pileup at 30 wpm is most likely not capable of accurately copying traffic at a reasonable speed. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
