Morse Code / Re: CW Operators needed...
« on: April 30, 2019, 12:37:16 PM »

Radio Relay International is awesome.  It's real communication, and reading through the after action report from the Cascadia Rising exercise produced by the U.S. Federal government , it put a smile on my face to see Morse operators juuuuust slightly win over the excellent PACTOR network.  Another factor in this exercise was to simulate the depletion of fuel reserves used for powering ham and municipal generators, which took some of the heavy data centers off the air, as would happen in an actual disaster of this size. The energy efficiency of low/medium powered CW with trained/experienced operators handling traffic really became extremely useful.

Remember: If you can't power your communication equipment, you cannot communicate.

1st - IT's been a few years and though that is how I remember it, CHECK YOUR MANUAL. The radio you save will be your own ;-)

2nd - If VWflier reads this, he can answer, because he bought it from me.

Yes! the external power port is how I powered mine and kept the internal battery as a 'reserve' when away from home.

Both are fine radios. As a dedicated rig for ultralite backpacking, the MTR series win hands down.  However, I found that I preferred the the Hb1b because of its versatility; it's good for signal search, is USB/LSB receive capable and SWLing as well. You made a good choice.  I only wish that they still made them with an 80m band, which is extremely handy for communication within that vitally important 'one-tank-of-gas- range.

C'mon, Andy,

You know that most Americans don't obey faceless distant bureaucrats, unless we personally believe in that particular regulation.   That goes double if it came from Washington D.C. ha ha

Military Radios / Re: PRC-320 Military Manpack Radio, First Impressions.

when I was working in Kuching, Sarawak, Malaysia , I picked-up a locally published book; "SAS In Malaya" and, like you said, Gil - the jungle warfare people did amazing things.  They Malay campaign drove the development of a far better radio;  the PRC-316 and STRONG reliance on NVIS.  Here is a link to an interesting article from your mates at VMARS, describing it's use.

I must say, RRI is quite impressive on the Morse side!  I have had not direct contact with the digital side, though I know one or two familiar operators there, and they have always top notch, so they likely are doing great work to make a PRACTICAL EmCOMM system. . 

The Morse traffic nets are very well organized, routing has obviously been the subject of much thought and improvements, since the days of the Trans Continental Corps (TCC) and enhanced with excellent upper eschelon management of the system.  I do not see ANY public politicking , and I plan to become rather deeply involved in RRI.

Without mentioning  it at the time, one of my check-ins was QRP (5 Watts) : It worked with no problem - so, it's practical at easily sustainable , emergency power levels.

Morse Code / Re: Can Morse Code Still Save You?
« on: August 31, 2018, 12:50:25 PM »
I've been following the comments to your excellent post.  Small wonder so many cannot comprehend Morse;  because evidently, they cannot comprehend what they read on the screen!

Time for a snack, then back to yard work. 

Ps.  Before I retired,  I worked in a world of split-second timing: now - a calendar will do nicely ;-)

Morse Code / Someone's Blogpost about Learning Morse Code

Gil has written about it, I have, others have.  Here is another fellow and he really did a good deed by writing of his recent learning of Morse code.

Thanks for postin over there, Gil.  It's a thought provoking article.  The Answer (tm) isn't always to pullout the credit card to buy a solution. A more reasoned , focused, minimalist approach is usually the best solution for when we are outside of the ham shack.

Data protection that protects you from reading foreign press... Reminds me of the Berlin Wall, which the Soviet and their vassal East Germans stated was to protect workers from attack by the western fascists.  With 'protectors' like that, who need enemies ?

Here is the text from the article:

Making do with what you have

"It’s been 12 years since I stepped on the yellow footprints aboard the Marine Corps Recruit Depot in San Diego, California. In the years since, the one thing I took for granted most was how much growing up on a ranch prepared me for the Marines and life in general.

Beyond the physical conditioning and endurance I gained from hiking fence posts and barbed-wire up and down butte rocks, I learned that I often times have to make do with what I have. If I needed it and don’t have it, I have to borrow it from a neighbor. If all else fails, I have to improvise with the materials I have on hand. The Marine Corps was no different.

One example of how ranching gave me a leg up was when I deployed to East Africa in 2008. I was one of four Marine radio operators in a joint communications shop run by the Navy. The shop used Marine Corps radios which none of the Navy guys had ever touched before. As a lowly Lance Corporal, I suddenly became the subject matter expert in the shop, responsible for training and solving complex technical problems.

Toward the end of the deployment we were given a tricky mission: find a way to talk via shortwave radio from Djibouti -- a tiny country in “the horn” of the continent -- to Nigeria, clear out on Africa’s west coast. The Nigerians didn’t have access to our satellites, so we had to rely on the High Frequency bandwidth utilized by HAM radio operators. However, when we measured it out, the shot was almost twice the distance of the United States from coast-to-coast. I instantly identified a problem: we’d have to get a more powerful transmitter and do some math and figure out how to make it work.

Boosting our power output would be a little tricky. The radio itself could only push out 20 watts of power, and the only amplifiers we on had pushed out 150 watts at-best. But before I could do anything about that, we’d have to track down a generator to power up my radios from a remote location.

Earlier in the deployment I’d made friends with the Navy SeaBees whose compound was right down the road from my shop. The SeaBees were the carpenters and engineers responsible for building the wooden huts and hooches that dotted our little desert base in Djibouti. They had a number of small generators laying around for power tools and the like.

I’ve learned that no matter how busy I get, I’ve always tried to pay it forward. Stopping to help out a neighbor has proven to come in handy when I’ve need help. It was around my first week in country, when a Chief Petty Officer for the SeaBees stopped in at the comm shop and asked if I could come over and fix their hand-held radios. After trouble shooting for a bit, I figured out a way to boost the output so that they could talk further. It improved the SeaBees’ quality of life and helped them get their mission accomplished.

When I walked in a few months later, the Chief remembered me and was more than happy to loan me a generator. I suppose that wasn’t much different from being back home and borrowing a trailer or a loading chute from a neighbor when it came time to work cows.

The next step in my mission was tracking down an amplifier. We’d done research and to purchase a beefier 400 watt amp from the radio manufacturer would have cost us about $200,000. I knew that was out of the question, and that the process of requisitioning one would take longer than I had left in country. So, I set out into the hot sun to beat feet around to the other units on the camp to see if anyone had gear lying around that they weren’t using.

Down toward the air strip I found a tent for a Navy aviation squadron. After visiting with their warrant officer, we learned they had a radio amp that’d fit our need. However, they were reluctant to pony it up to a couple of jarheads, and given the reputation of some Marines, I don’t really blame them.

I asked if there was anything we could trade out and learned they were having trouble with a satellite radio the used to talk to their planes. I went back to the shop to grab a spare high-gain satellite antenna and returned to set it up for them. Running the cabling for the antenna into their shop was a bit of a task, as I had to crawl through the sand under floorboards in 100-plus degree heat. It was a hot, miserable, dirty job, but after making the connection I got them up and talking, eliminating a major headache for their staff. The warrant officer was absolutely over the moon with the job we’d done.

“If you weren’t a man, I’d kiss you right now,” he’d said.

 And with a handshake, he agreed to sign over the amplifier we needed.

Having tracked down my power source and an amplifier I knew I almost had it in the bag. The only task left to make the project work was to build an antenna that would talk far enough.

In radio school we had a corporal who taught us how to make field-expedient antennas from telephone wire and the plastic MRE spoons. The spoons acted as insulators for the antenna wires and kept the radio waves from going back into the ground. When I think about how bootleg my methods were, it wasn’t too far of a stretch from the duct tape and bailing wire I was accustomed to using when fixing a tractor or a pickup truck.

After running some calculations and figuring out what frequencies I needed, I measured out the length of wire. I then used a compass to shoot an azimuth and point me in the direction of my Nigerian counterparts. We erected two 25-foot aluminum flag poles about 100 feet apart and attached our plastic spoon insulators before stringing the wires up between them. We then connected our amplifier and got the radio system grounded (400 watts is a lot of power, and we didn’t necessarily feel comfortable getting shocked by it).

We fired up our generator, punched in our frequencies, and connected the handset to the radio. I crossed my fingers as I keyed out and let the radio couple itself to the antenna. My heart was pounding as I spoke into the handset with the call-sign of the Nigerians we were trying to raise.

Seconds went by and I began to feel a swell of disappointment well up in my stomach. It didn’t work.

But then – a break in the static; a thickly accented voice came through the handset, responding to my call-sign. I’d set out to do something and made it work with what I had. With all of the technology and equipment the U.S. military spends its money on, all it took was a bit of telephone wire, some plastic spoons, and a Nebraska ranch kid borrowing from his neighbors."
