Morsum Magnificat

An excellent resource concerning all things Morse code.

The English language edition of Morsum Magnificat, the Morse Magazine, otherwise known as “MM”, contained a vast amount of information and illustrations of interest to Morse operators, key collectors, historians, researchers and other Morse enthusiasts.

MM was first published in the Dutch language, by Morse enthusiasts, Rinus Hellemons PA0BFN, and Dick Kraayveld PA3ALM. They were later joined by Tony Smith G4FAI who helped them launch the English language edition of the magazine.

Published from 1986 to 2004, in 89 issues, with readers and contributors around the world, it covered every conceivable aspect of Morse telegraphy, past, present and future, in a truly international way.

Issues are available at the Internet Archive here.

CW from the mobile

About twice a month I have the opportunity to scoot out in the morning to a nearby park for an hour or two. I use it as an opportunity to make a few contacts to make sure my mobile setup is still working well. This morning I was out at the Wyandotte County Park.

I was able to make five contacts on 40M. Some interference form shortwave broadcasts, but nothing that fully prevented a QSO. I enjoy using the J-45 leg key – it does not seem like it is a key built for speed. That’s okay for me as I am still somewhere in between 10 and 15 wpm.

When I get home and upload these contacts on to LOTW, I want to make sure that I have the correct location in TrustedQSL before I sign and upload the logs. I found two websites that helped me figure out the grid location for the park. The first is QRZ’s Gridmapper. The second website was a bit more user friendly and also provided the ITU and CQ Zones. After I set up a new station location in TrustedQSL and had transferred the contacts from my pocket notebook to my fldigi logbook, I exported the contacts and then signed and uploaded them via TrustedQSL into LOTW. Victory.

The Zombie Shuffle

I participated in a CW QRP event! Why not? It was actually a pretty good time.

The event: The Zombie Shuffle

The whole purpose is just to have fun. They are not looking for speed racer code operators and everyone is welcome.

The exchange is the best:
(1) RST
(2) your states
(3) a Zombie number, which is east to get. Or you can just use your area code.
(4) your Zombie name. This is the best part. You can just pick your own Zombie name being as creative as you want.

I had a total of 13 contacts (that’s pretty spooky in and of itself). Some of the fun names I worked were: Grim, Creepy, Gorigor, The Thing, Itt (as in Cousin Itt), Elvis, and Booger.

Fun stuff.

2022 – The Summer Trip

St. Mary Campground, Glacier National Park, Montana

Another summer trip has come and gone. This one did not feature any new locations or set records for being away from home for the longest time. We did discover some new trails in Yellowstone as well as getting to know older trails in Grand Teton in different ways. The consensus for favorite hike was the out-and-back we did in Paradise Valley, not far from Fishing Bridge in Yellowstone. Ask me some time about the Solfatara North trail with the grizzly who wanted to take us out to dinner (take us out as in kill us… and then we’d become dinner). Or maybe it is best not to bring that hike up at all.

At times it seemed like the odds might be against us. Primarily with the June 2022 flooding in Yellowstone potentially putting a large chunk of our summer at risk. A new menu prevailed with a few winners and a general request for less potatoes.

The wildflowers were sensational, as always.

The culminating event, when we were down to Emily and myself, was a hike around Jenny Lake. What a blast!

Something new this trip was my increased attempts at getting on the air this year. Usually I do very little amateur radio work on the summer trips. To be honest, I am normally either too busy or too tired to get on and enjoy radio. This year I made an effort to get on the air and see if I could make some CW contacts. Although I had visions (and most all the equipment) to setup an operators position at the back of the station wagon, I ended up making all of my contacts from the driver’s seat. Helping me was my J-45 leg key and my Field Notes memo book for handcopy. When I did get on air, I was generally successful in making contacts. My best luck was on 20M around the SKCC watering hole at 14.055 MHz. An enjoyable aspect to making the contacts was sending each one a postcard from the national park I was at… using the postcard as a QSL card. Overall, I made eleven contacts – beating any previous year by quite a bit.

Today I upload the contacts to LoTW after figuring out how to add the locations from where the contacts took place into my LoTW account (three separate locations). Then, after I had entered the contact information into my fldigi-based logbook, I exported the contacts, using the correct location, into LoTW. It was nice to see many of my contacts had already confirmed the contacts.

I do need to make some modifications of my HF vehicle installation. The display heads up front are great! Using the Ram setup really made things organized and solid. The FT-891 in the rack tray needs to be adjusted to mitigate its ability to bounce too much on a bumpy road. I also need to repair the feedline into the radio. This fall, I would like to try out a back-of-the-vehicle setup.

As always more and consistent Morse practice will always yield dividends.

Getting the J-38 into the fight

I have an old J-38 that I bought a few years back and it has remained in a storage container in the shack for too long. I got the key out today and connected it to the rig – it works, but is not much to look at. The goal is to get her to look good as well as sound good. Lots of advice concerning how to clean a J-38.

K6IX offers up the following:

Here is the method I use to clean my J-38 keys. Some key collectors believe that keys should be left exactly as they are found, but considering the construction, materials, and ubiquity of J-38 keys, I think that carefully and gently cleaning them is appropriate. Do not, under any conditions use wire brushes or other highly abrasive methods.

1. Disassemble the key. Look carefully for, and set aside, the positioning pins in the binding posts (if they are loose) and all of the fiber washers. Put the bakelite and hard rubber parts in soapy water. Put the metal parts in ammonia. Let both soak overnight. Don’t panic, because some of the metal parts will turn black.

2. Carefully wash off the bakelite/rubber parts. If the two knobs are very dull I sometimes us black shoe polish on them. The bakelite you can carefully clean with Flitz (see below) if it is still dirty or discolored.

3. The metal parts I clean first with “Nevr-dull”. It is a “wadding polish” product that I get here in a hardware store, but I think it is also sold in boat stores, grocery stores, auto stores, etc. It is manufactured by The George Basch Co., Inc., Freeport, New York, 11520, USA.

4. Then I clean some of the larger metal parts with “Flitz”, which is a metal/fiberglass cleaner made in West Germany and packaged in the USA by Flitz International, Ltd., WI 53185. It is available in boat stores, and I buy it from West Marine on the internet (www.westmarine.com). Just get a very small tube of it–it goes a long way. Flitz protects the metal from corrosion.

The most important step is #1. The soaking makes a big difference!

Another recommends soaking the metal parts in ammonia overnight and then the grime wipes off the next day.

Here’s another write up where bore cleaner (apparently ammonia-based) was used and met with good results.

Before I get too far along, I need to make sure all the adjustments and springs are still in working order.

More to follow.

Yes… the bands are open

Like you needed me to tell you about it.

I was initially licensed in 2001. Finally upgraded to General in 2005. Up to this point, my ham radio career has been under less than optimal propagation. From the oldtimers, I’d heard tales of 10 meters… when the sunspots where there, 10 meters could be worked around the world with only a wet clothesline (not even wet, just a bit damp). Frankly, it was hard to believe. My one prior 10 meter contact had been an opening QSO during the 2006 Field Day… Virginia to New York, some serious DX? [I thought so at the time.]

We’ve all heard the news… 10 meters is open. But from an HF standpoint, I was limited to my Buddipole, where I was nugging out CW contacts on the 40M Novice Band.

This weekend I threw up some wire and everything changed…..

Europe, the Caribbean, Alaska, 10 meter magic! (… I thought 6 meters was The Magic Band?) 10 meters was like a local 80 meter ragchew without the S5 noise floor, everybody has a 2KW amp, and the vast majority of the inbreds were nowhere to be found.

Thanks be to Apollo – may the sunspots continue!

Time to look about getting a 10-10 membership…. and, with a little luck, I might even have the cards for DXCC.(!)

…. need to put a map up on the wall.

Spy Radio: AN/PRC-64

Richard Fisher, KI6SN, had a post back in August 2009 that talked about an interesting transceiver that was in use by the military in the 1960s and 1970s: the AN/PRC-64. The radio is crystal controlled, limited to four channels between 2.2 to 6.0 MHz, has a max output of 5W for CW and 1W for AM PHONE. Its distinguishing factor is the rigs small form factor: 9.8 x 5.1 x 4.7 in.

What really makes this a spy rig is its ability to be paired with another device: the AN/GRA-71. The AN/GRA-71 is a burst encoder. The encoder allows the transmission of CW messages of speeds up to 300 wpm… some serious QRQ.

A government evaluation report on the radio concluded, based on tests conducted in Vietnam supporting Special Forces teams, that the radio had an effective range while operating in CW mode of between 40 and 300 miles. I imagine with both the power output and frequency range (and assuming the use of a field expedient wire antenna) the radios were not normally used for long haul communications… probably more like a range of not more than 75 miles.

10M?

Last week was busy – I spent the whole time down in Seoul attending meeting after meeting with my evenings spent on a bunk bed in a communal room (trying to save a little cash for Uncle Sam). The week was productive, but tiring. The main US military garrison in Seoul, Yongsan, has a lot of amenities that you will not find up at my camp. I got to enjoy many of the various restaurants located there as well as venturing off into Seoul itself, located just outside the gates. Two key finds in Seoul: a restaurant that serves American Chinese food and an Irish pub that serves Guinness from the tap. I enjoy Korean food quite a bit, but also like a variety. Most people know that Chinese food in the US does not come close to resembling the actual cuisine of China… and I have no problem with that. Serve me up some Orange Chicken or General Tsao and I am a happy man. Top it off with a fresh pint of Guinness… now you’re talking.

However, by Saturday morning I was still tired and unmotivated to put up my Buddipole… despite the lure of the 10M contest. I did have a QSO with my dad via EchoLink. He used an app on his Android cell phone and connected through my EchoIRLP node (EchoLink Node #496698 and IRLP Node #3370). My friend brought by some freshly made Hotteok. These pancakes are delicious and I enjoyed them while they were still hot with some coffee. Still wasn’t motivated to put up the Buddipole.

Sunday – the Buddipole went up. A 10M dipole with the Buddipole consists of only the 9.5ft whips on either side of the VersaTee. 10M was not really cooperating. In all I had only nine contacts: Australia, Malaysia, The Philippines, and Guam. Surprisingly, I only heard one JA and he couldn’t hear me. No stations from Asiatic Russia either.

After sunset, I switched the antenna from a 10M dipole to a 40M vertical. I thought I might look for some JA stations to practice my CW. I have yet to understand how the JA’s use 40M. The JAs can use phone down to 7.030 MHz. This compacts the CW to between 7.000 and 7.030 MHz. PSK-31 is suppose to be around 7.038, but I have never seen any PSK-31 traffic on 40M over here. I must be looking in the wrong place. Shortwave stations still come in at 7.100 MHz and above. So after sunset, all the 40M action is wedged between 7.000 and 7.100 MHz. So far I have not found any one band location where the QRS folks hang out (like the old Novice band in the US). Maybe with a bit more listening I can crack the code on how the JAs manage 40M.

As for the HLs… I’ve only heard two on the air. Where are all the HLs?

Here’s the good news… cue Bing Crosby… I am heading back to Kansas for leave this coming Friday! Christmas at home with the XYL and harmonics!!

A little DX

I spent Saturday filling out QSL cards, stuffing them in envelopes, and putting on $0.98 worth of postage for the USPS first class international air mail rate. To make life easier I ran both the return envelopes and main envelopes through the printer to get my address on. It would be easier to get some kind of mailing label sheets, which I think I will try to find when I get home for Christmas. Any way you slice it, filling out QSL cards and getting them in the mail takes a while. Keeping me entertained during the QSL card envelope stuffing session was the Insomniac Net through my IRLP node.

Sunday I woke up early and put up my Buddipole antenna, configuring it as a dipole for 20M. Exceptional DX catches for the day were:
UN7FU – Kazakhstan
WH0/WH7C – Northern Mariana Islands
FK8GX – New Caledonia Island
CW3TD – Timoteo Dominguez Island, Uruguay

I am continually surprised by my ability to work stations in South America. I’m not sure what path I am getting the propagation from. There is no one single time of day for my South American contacts – some are in the morning, others in the afternoon.

Today was the first day using my MicroHam USB III. The device is small, just larger than a pack of cards. The radio cable, which comes with the interface, is very well shielded. I used the USB III for both CW and PSK – the device worked well in both modes. Is the MicroHam USB III better than the West Mountain Radio USB PnP RIGBlaster? From a performance standpoint, I think it does a better. With PSK streams, I was able to detect and have QSOs with much weaker signals using the USB III. The fact that the USB III has its own soundcard is a big plus.

Almost done reading A Year of DX by Bob Locher, W9KNI. Bob details his year-long run in the CQ DX Marathon. The reader gets to sit side-by-side with Bob as he uses his Elecraft K3 and DX cluster alarm to work country after country. Bob demonstrates the importance of researching the various rare entities, determining when they might become active and how best to work them. The book is divided month by month, detailing the QSO with each new entity. Between the month chapters are useful chapters concerned with amplifiers, SSB phone techniques, and an amusing Walter Mitty-esque short story themed around DX contacts. I’m enjoying the book and recommend it (…potential stocking stuffer!).

Combustible CW

I had a QSO the other day with a gentlemen who was using a Navy flame-proof key. I had heard of the flame-proof key and knew that it was a military straight key – but I never really thought about why it was called flame-proof. If you have a sending speed >50 wpm, do you need to worry about fire breaking out in the radio shack? Well… the real answer is a qualified yes. I found the answer while perusing the Western Historic RADIO MUSEUM’s web page.

Many of the military keys were used with transmitters that were cathode keyed and sometimes had significant voltage on the key itself. Also, other types of equipment may have voltage levels or current levels that could cause sparking when the key breaks contact. This could present a problem in areas where flammable fuel vapors might at times be present, such as airplanes, tanks or ships during or after an attack where fuel tanks or fuel lines may have been ruptured and leaking. The flame-proof key enclosed the contacts in a sealed chamber to prevent exposure of the possible sparking to any combustible vapors so it would be possible to radio for help. The J-5-A on the left is a Signal Corps key that was introduced in the thirties but was built for many years, in fact the one shown is from WWII – built by L.B. Brach Mfg. Co. The key in the center is a Navy flame-proof key, the CAQZ-26026 built by Brelco Co. The key on the right is a British “Bath Tub” flame-proof key that is made out of bakelite. The bale clamp holds the upper part of the key (which has all of the key parts) down into the tub. There are many other types of flame-proof keys but all accomplish the same thing, isolation of the key contacts to prevent exposure of possible sparking to a combustible vapor.

… I am curious if the military actually learned this the hard way, deciding to encase the contacts only after an explosion or fire had occurred.
