Dick and I were taking our time enjoying the magical geology. Several times I was flooded with fond memories from forty years ago when my new bride and I walked up the same steps on our honeymoon. From the President’s Key By Tim, W3ATB When I got to the top of the pathway, there was a young couple who were trying to take a selfie photo of themselves. They were glowing and in the moment, but being a photographer, I knew the photo they were taking could be much better. I approached the young couple and offered to take a photo. They obliged. They giggled. Looking at the young woman, she reminded me of my wife back those years ago I said, “I want you to give him a big kiss and let me get that In This Issue Each month I try to use this space in the newsletter to increase the virtual sales of my happiness business.

The phrase happiness business popped out of my mouth sixteen months ago when Jim Cluett, Dick Christopher and I were on an outdoor radio outing at the Flume Gorge in the White Mountains. As we approached the top of the walkway through the flume, Jim scampered ahead as he was very eager to find a Next Club Meeting - Tuesday, Febuary 2nd, 2016 at 7:00 PM Gilford Community Church, Gilford NH 1 1 3 4 6 9 The Communicator Febuary, 2016 shot.” ished at what’s possible. She blushed a little but gave her boyfriend, or husband, or lover, a very passionate kiss. I took at least three photos, handed the camera back, they thanked me all the while laughing. If you’ve been a ham for ten or more years, then you know that Josh is just scratching the surface. Go ahead, push that paper surrounding you. Upgrade your license, try an upcoming public service event, built a small kit, go visit someone’s shack and get on the air and have some fun! I caught up with Jim moments later. He had been waiting for me for at least two minutes. “Where have you been? What were you doing with those two people?” “You may not realize it, but I’m in the happiness business. I was creating bliss for those two lovebirds now and in the future. Can you believe what they’ll think in forty years when they look at those photos of them kissing? They’ll remember the moment and no doubt laugh wondering about the old goat who took the photos.” CNHARC Repeater Sustaining Members 2015 / 2016 I think Jim shook his head and off we went to set up his KX3 just around the bend of the descending trail. No doubt he understood that I was trying to help the young couple, but by gosh getting a QSO or two that afternoon was important too!

I’m blessed to have a friend in this hobby that motivates me to push the envelope. Each month or two I’m encouraged by this friend to try something new or advance a little further in the hobby. “You need to upgrade to Extra because you’re missing out on some great Qs in parts of the bands outside your current privileges,” he said to me about two months ago. My current goal is to have passed my Extra exam on or before March 1st.

Repair Your Power Cord by Mike Stone, N1VE Over the years I’ve had several large capacity power cords separate from their molded plugs. The exposed wire conductors can become vulnerable to damage. Step #3 Warm the tubing with a heat gun until it is flexible I have had success repairing the separation, using a two-inch length of PVC conduit (PVC water pipe, or other suitable non-metallic tubing can be used), electrical tape, and PVC cement. Step #1 Use a hacksaw to make a longitudinal cut along a two inch long piece of tubing with an inside diameter the same size, or slightly smaller than the diameter of the power cord. Step #4 Spread the sides of the tubing and slide it over the extension cord. CNHARC is on YouTube ! CNHARCAmateurRadio 4 The Communicator Febuary, 2016 Step #5 Squeeze the heated tubing until it fits snugly over the power cord. It might be necessary to reheat the tubing. Use gloves or a suitable tool to hold the tubing if necessary. Then slide the tubing along the cord until it rests firmly against the plug. Step #7 Apply two heavy coats of PVC cement to seal the tape. Let the cement dry between coats. Old PVC cement that is more viscous than fresh cement and will produce a thicker and more durable seal. Step #6 Tightly wrap several layers of electrical tape around the PVC tubing, the power cord, and the plug, firmly binding them together. The completed repair.

Night Net 8 PM, 53.770 MHz 5 The Communicator Febuary, 2016 Sometimes things don’t go according to plan. This month’s column was going to be about something else entirely, but after writing nearly two pages of it, I realized that it wasn’t going anywhere. I know that writers often have “writer’s block”, but that wasn’t the case. The words were tumbling out of my brain and settling down into neat little rows on the page just as quickly as I could type them. What I was writing conveyed my ideas properly and made good sense. The problem was that it just plain sucked. output to be up around 60 to 70 dBm. That’s actually not bad for most things like PSK and SSTV, but for small signal modes like WSPR it can cover up some of the fainter signals. There is a small hack that involves re-routing the power inside the Signalink USB, that has the potential to bring the noise floor down to 100 dBm or lower! However, this hack involves modifying a device that probably cost you over $100, and will definitely void the warranty. Also, any mistakes could ruin the Signalink USB, which would result in a very bad day for you and possibly an eruption of words you wouldn’t want your children to repeat. I’ll be the first to admit that I’m not the best writer in the world. I know I have received a lot of compliments about these articles, and I appreciate every one of them, but I know that there are far better writers out there (including my own wife, Maria, who writes brilliant novels for young adults). That being said, the article I was writing just wasn’t good enough by my own modest standards. It was, for lack of a better word, BOOOOORRRRIIING. The following web site should be required reading for anyone who actually wants to undertake this mod: http://www.frenning.dk/OZ1PIF_HOMEPAGE/ SignaLinkUSB-mods.html So I saved it in a different folder and started over with a blank screen, and tried to figure out what I could write about that wouldn’t bore readers to sleep. There you will find the details on how to do this, why to do this, and what the mod will do for you. There are also some other mods described there that you may or may not wish to try as well. That’s when it occurred to me: What about ham radio related hacking? To be completely clear, a hacker is someone who makes use of things in ways that they were not designed to be used. A person who turns a dead flat screen TV into a photography light source, for example, could be said to be a hacker. Hackers are, despite many years of articles in the popular press to the contrary, mostly harmless. Most of us (yes, I consider myself to be a hacker, though not a very good one) try to do good things intended to improve our lives and those of the people around us. Here are some examples of some hacks that I have done to improve things for myself: 1: The Noise Floor Is Too Noisy. The Signalink USB is a fantastic little device that makes connecting a ham radio to a computer about as simple as it gets. With the exception of setting the jumpers inside the device, it is just about plug and play. However, it has a small design issue that causes the noise floor on the For anyone I haven’t scared out of doing this yet, here CNHARC is on YouTube ! CNHARCAmateurRadio 6 The Communicator Febuary, 2016 is the short version how-to: Carefully remove the 1KΩ SMD resistor between the TX and RX potentiometers. Solder a 470Ω resistor between the point shown above, and the 4.7KΩ SMD resistor next to JP4, as shown in the same image. Simple enough, if you don’t accidentally damage the device, which is very easy to do. I strongly suggest that this mod only be undertaken by people with good soldering skills. read online, and we all know that the internet never lies, right?). Using the dynamic element should, in theory anyway, make my voice sound pretty much the same as it usually does on the air, rather than making me sound like I’m talking from the other side of a large, wobbly piece of sheet metal. Getting that dynamic element to sit where the D-104’s original, much larger element sat wasn’t difficult, thanks to a couple of bits of foam rubber I had on hand. I used those to fill in the gaps before carefully marking which wire went where and screwing the back cover back on the D-104’s head unit. One quick note for anyone attempting to do this same mod: Do not unscrew the screws on the front of the D104’s head. They are decorative only, and you will probably damage the mic if you try to remove them. The mic head is accessible by removing the 4 screws on the back side of the head unit, not the ones on the front. 2: Which Mic Does Mike Want? This mod was inspired by my friend Mike K1MIC, who did something similar recently with his D-104 and encouraged me to stop letting mine collect dust. The Astatic D-104 microphone is an old favorite among hams. In many photos of ham radio benches from years past, the big silver lollipop mic can be seen sitting proudly front and center on the desk. These days a lot of hams are switching to Heil boom mics, but some of us more nostalgic folks prefer the old D-104. The problem comes when one tries to hook up an old mic to a modern radio. The crystal element in the D-104 gives a very tinny sounding output, and the built-in amplifier is not well suited for being connected to today’s more sensitive transceivers. My particular D-104 is the Silver Eagle version, made during the late 70s and early 80s when everything cool had patriotic sounding names and emblems containing eagles in majestic and entirely unnatural poses. It also has both the “chicken choker” PTT, and an extra one on the base which was mechanically attached to the chicken choker on the mic’s stem/shaft/whatever-you-want-to-call-it. Since I wanted to keep this functionality, I removed the Yaesu’s PTT microswitch and wired it directly to the Astatic’s PTT switch. I then wired the tone switch to a small toggle switch that I had made a hole for on the base of the mic, and then stuffed the Yaesu mic’s PCB into the base of the D-104 with some more foam and closed it back up. So if you want to have your lollipop and eat it too, you have to come up with a solution to these problems. My solution? I gutted the thing. In all seriousness, I carefully removed the existing electronics and mic element from my 1980-ish vintage Astatic D-104 and set them aside. If I ever decide to return it to factory condition, I’ll have the parts on hand. I then set about installing a new set of guts which were kindly donated by Yaesu when I bought my FT-857D five years ago. Well, not really donated... The radio came with their MH-31 microphone, but I replaced it right away with an MH-59 remote control mic. This mic is a rather expensive add-on, but well worth it in my eyes, as it opens up many of the features of that great radio that would otherwise have been buried in menus. So anyway, the MH-31 sat wrapped up inside the radio’s original box. In all the time I’ve had the radio, I’ve never spoken into that mic. Here’s a picture of the mess I made: Sounds like a good transplant donor to me. It wasn’t difficult removing the old Astatic parts from the big silver sucker, and it was even easier to remove the still beating heart from the MH-31. The Yaesu mic uses a dynamic mic element, so it handles a much broader range of audio frequencies than the Astatic’s crystal element, which is designed to carry only the higher vocal frequencies to assist in punching through static (or at least that’s what I CNHARC Monday Night Net at 8:00 PM on 146.985 MHz 7 The Communicator Febuary, 2016 Much to my surprise, it actually worked, and worked well! In fact, I used it to run tonight’s weekly 6-meter net. com. If writing my email address that way actually fools the programs that prowl the internet looking for such things, I’ll eat my hat. 3: I Need Some Light Over Here! I’ve had a few years now to get a good understanding of what a good ham shack should be: It should be well lit. FOR SALE We live in interesting times. In years past if you needed something, you would have to get in your car, drive however far away the nearest (insert store type here) was, and hope like mad that they actually had what you needed in stock, before making the long, slow trip home empty handed. These days, we have Amazon.com! One of the things you can find on Amazon.com are rolls of LEDs with sticky-tape on the back. These can be mounted just about anywhere you need light. Furthermore, these LED strips only cost around $7 - $10 each. Further-furthermore, they can be powered by 12 volts DC. I can’t imagine where a ham might get access to 12v DC power near his/her shack, can you? Astron RS-12A power supply I used it to power my echolink node which is now out of service... So it should be in good running order... $45. Two portable ground plane antennas, one for 2M and one for 6M. I call them portable because they are easily disassembled and assembled, consisting of four horizontal radials and one vertical radiator. While they offer little gain, they can easily be attached to one or more sections of mast and put up in the air where they will provide a better signal than a mag mount on a file cabinet. Good for emergency setups. I'm looking for $15 for the 2M unit and $25 for the 6M antenna. Needless to say, adding two or three of these strings to your shack/bench/workshop area can really light things up for you. Further-further-furthermore, they can be installed in almost any orientation, can be cut into small strips, or left at their full 16 foot (5 meter) length and be wrapped around everything including but not limited to the family pet. Our cat wasn’t happy about this, your own results may vary.
