With the summer season definitely here, Joyce (K0JJW) and I climbed W0C/SP-089, an unnamed summit east of Buena Vista near Trout Creek Pass, for a Summits On The Air activation.  This summit is also referred to by its elevation: 10525. The mountain is quite majestic with a large rock face that rock climbers enjoy climbing.

To reach the summit, we drove a 4WD truck from Trout Creek Pass on Forest Service Road 311, connecting to FS Road 373. Four wheel drive is required for this road due to the steep sections, which may not be passable in muddy conditions. You can also approach from the Buena Vista side, see the San Isabel Forest Service Map. From 373 we took a side road (shown in blue on the map below) that is not always shown on maps. I believe it is marked 373A but I am not sure. We parked the truck at the lat/lon shown.

From there we hiked a non-technical route to the west of the summit, working our way up through the draw shown on the map. There were a few faint game trails here and there but mostly it was some challenging bushwhacking up that draw. The willows and sticker bushes made us glad that we had long pants on.  Also, there was quite a bit of downed timber to step over. The route got quite a bit easier once we got to the top of the draw, but still no trail. The elevation gain was only 1100 feet but it felt like a lot more work than that.

As we neared the summit, I heard Bob (W0BV) calling me on 146.52 MHz. I had put out an email alert to some of the hams in the area so Bob and some others knew I was going to be out climbing. Once I got to the summit, I contacted Bob (W0BV) and quickly had a mini-pileup with several stations calling me. Mark (KF5WCY) visiting from TX gave me a call, followed by Carl (K5UK) near Mount Yale. Then I worked Jim (KD0MRC) in Buena Vista and Larry (KL7GLK) in Leadville. Thanks, guys, for getting on the air and contacting me!

I used my Yaesu FT-60 handheld transceiver and a 1/2-wave vertical antenna for these contacts. While I had my 3-element Yagi antenna with me, I did not bother to set it up.

My spouse and hiking companion Joyce (K0JJW) and I have worked out a standard SOTA activating procedure. As we get close to the summit, she stops below the activation zone and I continue to the top. Then I work her on 146.52 MHz which guarantees a successful activation. It is possible to get skunked on 2m fm in the backcountry, so this is good insurance. This one QSO does not result in any SOTA points, since the rules require a minimum of four contacts for activation points. Next, Joyce joins me on the summit and we work whoever is out there. Lately, I’ve had pretty good luck getting at least 4 contacts on 2m fm. On the descent, she stays on the summit and I go down the mountain and work her once I am outside of the activation zone. That way, I am able to work the summit, too.  Then she leaves the summit, catches up with me and we descend the rest of the way together.

It turns out my recent message purporting to have been sent for the International Space Station (ISS) was not from there at all, but from a tent in Wales! Not quite sure why people get a kick from this? It all seems a bit silly to me. Previously this person’s account was sending out dodgy links and I informed him of this.  Be warned – all may not be what it seems.

After a long, cold Sprinter (that’s what you get when Winter seems to last endlessly into Spring), Summer is finally here! Yay! And as promised, as of today, numbers are being assigned for the 2014 NJQRP Skeeter Hunt.

The Hunt will be held on Sunday August 10th this year – and right now, the best place to see the rules is at  http://w2lj.blogspot.com/p/njqrp-skeeter-hunt.html. I am trying to get the QSL.NET page updated with the new bonus points rules, but the server seems to be down right now.

Yes – bonus points this year for gathering enough letters from callsigns to spell out the word “SKEETER”. 100 extra points will be added to your score if you accomplish this feat. In any event, the NJQRP Skeeter Hunt is a grand time and folks seem to enjoy themselves a lot, so send me an email ([email protected]) and reserve your Skeeter number today.

Today was also the Raritan Valley Radio Club annual hamfest, which is held at Piscataway High School, in Piscataway, NJ.  The weather was absolutely beautiful – perfect for a hamfest!  It was sunny and it got up into the high 70s.  Very nice, but yet not exasperatingly hot. And as you can see from the two quick photos that I snapped with my phone, there was not a cloud in the sky. Unfortunately, it was perfect sunburn weather. Reporting time for the hamfest workers was 5:00 AM and as I was driving to the hamfest site, I had realized I had forgotten to bring sunscreen.  I discovered the hard way that there are NOT a lot of places open at 5:00 AM where you can buy sunscreen!

There were plenty of vendors and lots of buyers. The ARRL had a presence with the appearance of Bill Hudzik W2UDT, our section Vice Director. (Psst!  It helps that he’s a club member!) We also had a VE Exam session, where three people earned their Technician licenses, and we also had one upgrade to General and one upgrade to Extra.

In the top photo, you can see the huge mast sticking up from an old broadcast van that Brian N2MPM had acquired. Running up the mast was a PAR END-FEDZ antenna that Alan W2AEW using to make QRP contacts.  If you follow this blog, you know that I have mentioned Alan’s YouTube videos in the past. He does an excellent job producing videos on how to use test equipment and other neat technical tutorials. If you haven’t subscribed to his YouTube channel, then you are cheating yourself. After you read this go over and subscribe – it’s definitely worth it.

Here’s a video he took of today’s festivities:

Pulling off a hamfest like this is a huge undertaking. Thanks to the direction of our two Hamfest Committee Chairmen, Drew W2OU and Rich W2PQ and all the members of the RVRC, this comes off flawlessly – year after year.

In between my duties of assisting with the parking and placement of the vendors, and being the lead in administering the VE session, I did get a chance to look at the various wares on the tables.  I purchased some BNC to PL259 adapters and some large alligator clips that we will to connect to batteries that we will be using next weekend during Field Day. Not a big spender much to the discontent of the vendors, but much to the delight of my wife.  😉

I’ve been up way too long and am making way too many typos – even more than I usually make, so it’s off to the sack for W2LJ. (Thank God for spellcheck.)

As you will recall, my antenna on 40m is very low and not that efficient: it is just a 10/20/40m Par end-fed with an average height above ground of 4-5m at most. Last night I was on 2W. I hate to think how low the ERP would have been on 40m!

Overnight 17 unique stations spotted me with best DX AE2EA (5654km). Even with a low and inefficient 40m antenna, WSPR still works well!

As a (now-retired) broadcast engineer, I grew to hate the LM-386.  It always seemed to me to be difficult to control and to be prone to oscillation.

My own solution was to switch to another chip for audio amps.  My own choice was the TDA2822.  It’s inexpensive and easily available from Mouser, Digikey and others.  It’s a dual amp, which is handy for stereo, but I use it in bridge mode even when I design mono amps.  My choice is the SOIC-8 package, which is large enough to be easy to use, but also saves pc board space over the DIP-8 that’s usually used on LM-386 chips.

My general tips are to carefully bypass the power supply for whatever chip you use.  I’ve often used 4.7 ohms or so in the supply line, and tried to bypass it close to the chip with an electrolytic, a .1 uF and a 20-100 pf chip capacitor.

But the MOST important tip for taming IC audio amps is to connect a small capacitor (I’ve usually used 33 pf chip caps) between the inverting and non-inverting inputs.  It tamed lots of otherwise-troublesome amps for me.

I read about many homebrewers purchasing electronics from China on e-Bay. Many of these are major purchases such as test equipment, FM handhelds, antennas etc. The vast majority seem to be happy with their experience while some are clearly not.













I happily admit that in all cases, I have been very pleased with not only the quality of the items received but also in the service. With the high cost of shipping anything to Canada, I find the 'free shipping' for all of these items to be particularly attractive.

Although all of these items are available from many e-Bay sellers in China, I think it pays to carefully search feedback records before purchasing. In many cases, a high rating does not always tell the story. I look for high volume dealers that have very few complaints within the past year. Check what complaints are being made...if it is the quality of what is being sold, then go elsewhere, as some dealers do a high volume of selling junk while others have only single-digit or even zero negative feedback.

It will still be some time, if ever, before I feel comfortable buying any high priced items from China but if you were brought up in the 50's, you will probably recall when buying from Japan was an invitation for disaster and look how that turned out!

73 to AD7MI and welcome to NI0L…

…. and a no frills QSL card.

My retirement from the Army is both official and complete as of May 1st. The XYL and I have decided the land of &#216 is where we are putting down our roots. Therefore it was high time that my callsign reflect my geographic location.
