Two contests, one rock

Camping

I could say that we selected Rocky Gap State Park (78.65061 W, 39.71315 N) for Memorial Day camping because I knew I would be running a rock-bound transceiver in a QRP contest, but the truth is that as usual we waited until the last minute to make camping reservations, and there weren’t many choices for state parks within a three hours drive of Washington, DC. Despite the  last minute preparations, the camping went off without a hitch (literally, since we shoved everything in the back of one car).

We left early on Saturday morning, had tents up by around noon, and I then spent some time entertaining the neighbors by throwing soda bottles with strings into the high trees. In appreciation, they turned up their country music, which was much appreciated, but not by me.

This was the CQ WW WPX CW contest weekend, so I knew there would be a ton of activity, with a good chance to be heard internationally. For that contest, I brought the TenTec 1320, and ran its ~ 5W into a longwire antenna through my Hendricks SLT+ antenna matcher. That rig only tunes 20m (~14.003 to 14.073), so I was limited to daylight plus a bit. With other camping activities going on, I periodically sampled the band to see what propagation paths were open. I was using a straight key as I don’t have my keyers on hand, but it wasn’t too bad since I wasn’t calling CQ much with such a peashooter station. Logging was performed in the classic style: paper and pen, with a lot of page flipping to avoid dupes.

The late afternoon/early evening both days was my best time. I logged 31 contacts, with DX to Aruba, Canada, France, Germany, Italy, Martinique, Spain, and Venezuela.

The CQ contest was over at 20:00 local time on Sunday, just in time for the ARCI Hoot Owl Sprint to begin. I had brought the 40m rockmite for this contest, since the contest offers bonuses both for QRPp operation and field operation. With the large membership of the ARCI potentially listening, I thought I might have a chance to be heard by someone.

I started at 20:00 EDT (00:00 Z) and stayed at it for 3 and a half hours, before I decided to walk down to the lake and stare at the clear night sky for a while. The rockmite has a built-in picokeyer, so I was able to use my Bencher BY-1 paddles, which was a good thing since I was somewhat zombified that late in the evening after a good night’s sleep on hard ground the night before.

Rumors may have exaggerated somewhat

Not only did I log some radio contacts, but I also was visited by many species of insects, who were attracted to the coleman lantern providing light for the log book. In fact, one unlucky bug is a permanent addition to the logbook itself.

In all, I logged nine contacts in six states (MI, NC, NJ, NY, OH, and VA). Five of these contacts were with ARCI members, who gave their member number in exchange, the rest sent me their power, some QRP, some not. I assume for the purposes of the contest in terms of my score, my power matters, but not theirs. Because I was operating on the rockmite at 500 mW output, my score got a 10x multiplier. Even more helpful, I got an additional 5000 points for operating portable (a bonus ~3x bigger than my score itself).

Operating with the Rockmite takes some patience, as the bandpass is large enough to hear many simultaneous conversations. When stations reply, it can be hard to tell if they are zero beat or not, particularly if they send just their call rather than “ai4sv de mycall mycall”.  Infrequently, I also had a touch of broadcast band interference, which faded in and out, and was always too tenuous to pick out specific spoken words.

Rocky Gap State Park was not chosen based on its potential as a contest location, but it worked well as one. The park elevation is about 1200 feet, and we were in site 182, which is at the far end of one loop, at the top of a hill, and surrounded by woods. Our site did not have electrical feeds, which further reduced the noise.  The entire site is in a valley, however, with taller hills to the east and west, so some low angle radiation may not have passed.

I would certainly consider Rocky Gap again for family camping, but I have my eye on some sites that are both closer and more elevated, for instance in West Viriginia, Black Water Falls (elevation 2897 feet) or Pipestem Resort (elevation 2690 feet, plus it has the word “Resort” in the name).

 

No QSOs in Boca Raton

This started as more of an IF (interactive fiction — not intermediate frequency) blog, but it does make a lot of sense to consolidate other topics here as well, since most of the time when I have to list a “blog” or “web site” link, I list this one. So, consider the flood gates opened. That probably means a flurry of excited posts followed by intermittent (on a geological time scale) dry spells. Let’s face it: that’s just how I am about updating websites. Maybe postings will be more regular if I can broaden the scope of the posts to just about everything and if the blog posts are useful to me as a sort of lab notebook.

Along these lines, one topic I’d like to document is ham radio trips, which I will conveniently define as any time I am not at home and get to play radio. Since I take a lot of trips for work, and since I almost always take a radio along, there should be a bunch of these.  Very often, the conditions aren’t optimal, and I don’t have a lot of time on trips, so more often that not, I probably won’t make that many contacts, but it’s more the effort than the QSO count.

Rather than recount projects and outings to date, I’ll just start from here forward. This weekend, I spent a couple days in Boca Raton. Scratch that. That’s how it is listed on the map — it is actually Deerfield Beach, Florida.  It’s only a beach if you consider concrete to be beach-like. It’s inland a few miles, and the view was of route 95. The conference I was attending was held at a resort that actually *is* in Boca Raton and overlooks the the ocean, but  I’m travelling at government rate, and that only goes so far.

My room was on the third floor of the hotel, right near the front entrance, which made antenna placement challenging.  On the first evening, I bid my time until there were no cabs or cars in the oval driveway, and then lobbed a 65′ long wire over a palm tree. I had attached it to a water bottle, and A long wire antenna running from the window to a palm treecouldn’t see where it landed after I gave it a toss. There were a couple tense moments when I went looking for it outside and found it dangling 20′ above the driveway, over the heads of some oblivious guests. I managed to yank it back a bit and get it into the bushes. Later that night, after dark, I guyed it down more substantially. Most of the antennas was elevated at about 35′, with the distant end down lower. I ran a 35′ counterpoise around the room and tuned the whole thing with a Hendricks SLT+ tuner.

The rig du jour was the 40m Rockmite, with the 7028.0/7028.9 crystal, running from a 7.2 Ah absorbed glass fiber lead acid battery. A picokeyer was built into the rockmite, and morse code was generated by a Palm Paddle which was duct taped to the battery. Where the wire crossed the metal window frame, I wrapped some duct tape around the wire as padding and then closed the window snuggly. Luckily, the hotel cleaning crew didn’t mind wires sticking out the window, and left the whole thing intact while I was attending my meeting on Saturday.

So far, I have had two — count them, two — contacts on the rockmite, but considering that it only puts out 300mW, that’s not too bad. Both have been from home using my 43′ vertical antenna (which is nothing more than a vertical wire radiator slung into a tree plus a few ground radials). One contact was across town, the other was to Michigan.  In the Michigan case, I was responding to a CQ call, and it was a difficult QSO.

I had no problem hearing other stations calling on 7.028 plus or minus 1 khz. Powerful stations would cut across both of my frequencies, and I had to wait them out. I heard strong signals from Italy, Slovakia, Slovenia, Germany, Croatia, France, and around sunset, from Columbia. Some strong local signals (SC, GA) were zero beat, but I could not work them. I called for a few hours intermittently, but had no responses. Well, maybe some qrz’s, but I am not sure to whom they were replying.

This was the first I had tried out the SLT tuner with the rockmite. Interestingly, the rockmite is powerful enough to illuminate the LED that tells you when the system is resonant. I would have wondered if my signal were getting out at all, if I had not had some confirmation from the reverse beacon network. Apparently, I was just above noise for a few of the stations, but at times, my signal was pretty decent (also, though, taking into considerations that the receiving systems for some of these reporting stations have high gain antennas).

So, no bites, not even nibbles, but considering that the antenna was somewhat of a compromise, I’m not writing off the rockmite. I am, however, strongly considering finishing the Texas Topper amplifier, which would boost the signal nearer to 5W and give me a fighting chance when my antenna options are limited.
