SOTA/POTA Activation on Mt. Pack Monadnock Coming Up

On Saturday, June 10th we’ll be activating Miller State Park (POTA KFF-2662) and Mt. Pack Monadnock (SOTA W1/HA-041) in Peterborough, NH. This is also the date of the ARRL’s June VHF contest!  Miller State Park does have an auto road up Pack Monadnock and there is a $4 fee per person.  There are picnic tables at the top if you would like to pack a lunch. I am thinking we should plan on arriving at 11:00 am and hopefully set up and ready to go by 12:00 pm.

This should be a great opportunity for a wide range of our members to get out and activate portable. With three activities going on we should have something to tickle your fancy. Below is a quick description of each activity with links for more in depth information.

SOTA is an amateur radio award scheme for people who want to get out and operate portable from mountain peaks. A couple of important rules for SOTA are that you can only activate a peak once in a calendar year – so if you’re using your own call sign you won’t be able to activate Pack Monadnock again until 2018 – and you must operate separately from your car (nothing attached – antenna, battery, etc) and you cannot use fossil fuels.  You must operate battery, solar, wind, hydro powered. You may work all modes (CW, digital or voice) on all bands.

POTA (Parks on the Air) is much more lenient, as far as operating possibilities. You, or your vehicle, must be totally within the park and you can operate using fossil fuels (generator or car). Parks can be activated more than once in a calendar year and QSOs are cumulative for the park if you return. Here is a link to a quick description for getting started with POTA. You may work all modes (CW, digital or voice) on all bands.

ARRL June VHF contest begins on Saturday at 2:00 pm and runs through Sunday at 11:00 pm.  I have never participated in a VHF contest, but being on top of a mountain can only help!

In order to keep some organization to the activation, I have created a Dropbox file for members to sign up and list any equipment they would be willing to bring.

Let me know if you have any questions, suggestions, etc.

QRP on the AIR… from K-ONE Last Good Question

By Dennis Marandos – K1LGQ

What a difference 90 days can make! It wasn’t that long ago we were looking out our windows and pleading with the snow gods to give us a break, and finally, our cries were heard. The temperatures, the blue skies, the winds have all been recently favorable and we can’t even remember what it was like with four-foot levels of bleached, hard bursts, hoar frosts in our front yards and drifts even higher. Well, we would much prefer to forget last winter than try to remember forging paths to the house garage, the grocery stores, to work or simply just getting our mail in the front yard–but look at it now. The sun is higher in the sky, the temps are thirty to forty degrees warmer than before, and the winds have shifted, a bit, for us to say “We’re in pig (HAM) heaven!”  What does all this lead up to you say? It is nature calling us to get out of the stale-air shack and into our “get-off-our-fanny” modes…including hiking, camping, biking and just plan QRP along the mountain paths. Yes, it’s the call of the CONTINUOUS WAVE!

I have been waiting all winter for the warmer spring months so I could pack my QRP gear into my knapsack, charge up the ole gel-cell and retune my throw-up dipoles to GET ON THE AIR. I have a small 7-amp gel-cell which is pretty much all anyone needs and thin, copper wire to fling onto the nearest tree limb to get the RF into the ionosphere. A quick and grubby antenna tuner will certainly do the job plus its pocket size which means not a lot of space occupied in the QRP bag. Overall, it’s pretty easy and if you’re thinking you have to do a lot to visit Mother Nature’s playground in her best, you’re wrong. Outdoor operating is now easier than it has ever been, and I am going to tell you why.

First off, operating QRP means you take the least favorable weight, carry less with you, and enjoy what you have. Five watts, or less, is pretty slim-pickings and to throw an antenna into a tree is the least of your hardships, but getting outside into the woods, the parks, the BACK YARD is going to be your toughest struggle. Where can I go? Who can I go with? How much gear do I need? Do I need to bring food, coffee, or snacks where I am headed? OH COME ON! We’re talking simply getting outside and into the sun and on the air!

I have built over two dozen QRP transceivers and perhaps as many antennas as well for the trickiest trees around. What you need is simply a low power rig that can be easily driven by six or eight double-AA batteries, or even a Lithium alone will get you on the air and you’re in attendance. Have you checked the pages of CQ magazine or QST to see who is selling QRP transceivers? Or better and easier, ‘Goggle’ QRP kits on your computer and you’ll find a utopia in front of you. Come on, the longer, brighter, sunshine days are here and you need to get moving before that cool breeze from the north comes visiting again. Not to worry, it’ll be a while, so warm up the soldering iron and burn some rosin. Just target the “al fresco” rig and get moving. By the way, bring your key, paper, and chronographic meter as well.

What does it take to get you moving? Okay, let’s suppose someone offered you fifty dollars to join him on a hike. Now, you’re outdoors and you’re loving it. Well, tell yourself that simply taking your gear to the woods is worth more than fifty dollars and look how much you saved. Think of mind relaxing thoughts, soothing, refreshing sunshine and the thrill of working QSOs anywhere someone can hear you. Now—doesn’t this bring a little excitement to your hard pressed schedule? YES, IT DOES! Now get moving…!

Add CTCSS PL Tones to Your Old VHF Rig

Last week I gladly accepted a free Azden 2m FM transceiver model number PCS-4000 that was offered to me.  You have to love the old free stuff!  The only capability this 25W rig was missing is the ability to transmit CTCSS PL tones or sub audible tones to activate a repeater.

I found the manual and schematics online and found that this rig was built to accept a tone generator as an add-on. See below.

PL Tone Mod Circuit

Below is a photo showing the jumper locations for the tone input.  I soldered some leads with a home brew disconnect to easily remove the cover in the future.PL Tone Mods

Below is a photo showing an added 1/8″ mono jack for the input tone.

PL Tone Mods

For an input tone, I used an Android cell phone with a frequency generator App to generate the PL tone.

PL Tone Generator

I can experiment with other ways to generate the tone such as an Arduino with RC filters etc.  I can also try to insert a 700 Hz tone with my Arduino keyer for MCW.

Below is a photo of the rig set up for a local repeater.

So now to quote Pete Juliano “Bob’s your uncle”!!!
