Great Time with the Colorado QSO Party

Posted on by

I had a great time working the Colorado QSO Party ham radio contest on Saturday.  This is your typical state QSO party where the rules favor working Colorado stations with an emphasis on activating Colorado counties.

I operated from our cabin located in the somewhat rare Park County, using my new FT-950. I am still getting used to the radio as it has more buttons and knobs than any other rig I have owned. I can tell that I am learning the radio as I was able to take more advantage of the contesting features.

Recently, I picked up a Heil Pro Set headset with the HC-4 mic element. I noticed that the serious contesters gravitate towards using a headset, logging computer and foot switch. This sets you up for a very focused operating setup with your hands on the keyboard and your foot pushing the transmit button. I was very pleased with how this worked out. I used N1MM software for logging and the antenna was a trap dipole in the trees.

I operated exclusively on phone as I don’t consider my CW skills up to the task of an HF contest. Maybe someday I’ll give that a try. Most of the time was spent on 20 Meters which produced contacts across North America. 40M was great for working stations around Colorado and picking up different counties.

Here’s my score:

 Band    QSOs    Pts  Sec   Mul
      7   81     162   30    1
     14  197     388   34    0

    420    2       4    1    0
  Total  290     584   68    1

Colorado 14er Event – Sunday!

Posted on by

I am getting ready for the Colorado 14er Event tomorrow morning. Here’s the brief description from the www.14er.org web site:

Amateur Radio Fun in the Colorado Mountains
Sunday, August 7, 2011

Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around the world. Join in on the fun on the Sunday of the first full weekend in August and see how many of the mountaintop stations you can contact. The prime operating hours are from approximately 9 AM to noon local time (1500 to 1800 UTC), but activity may occur at other times during the day. Most mountaintop stations will be running low power handheld radios. Stations running high power need to keep in mind that they can interfere with stations they cannot hear.

Radio operators with 14er climbing experience who plan to climb a 14er should log their name and intended peak at the HAM 14er Yahoo group.

Joyce K0JJW and I will be heading up Mount Antero, taking the Jeep as far as we can and then hiking the rest of the way. It should be fun!

There will be a crew of Boy Scouts on Pikes Peak, using club call sign KB0SA, so look for them.

You don’t have to be on a mountaintop to play in this event. Here are a few options:

  • See who you can work from home on 2 Meter FM and 70 cm Meter FM. The frequencies are listed on 14er.org.
  • Operate from a high spot that is line of site to the 14er summits. For example, Wilkerson Pass (west of Colorado Springs on Highway 24) is a great spot. Harder to get to but even better would be Mosquito Pass or Weston Pass. Trail Ridge Road in Rocky Mountain National Park is another great drive-to location.
  • Work the 14ers on HF. Many of the 14er stations will be up and running on HF and there is usually a pileup of stations wanting to work them. The Goat Hiker crew WG0AT will be out in full force  on Handies Peak, likely using N0B special event call sign.

See you on the air!

Finally, A New HF Rig

Posted on by

My wife and I have a cabin up in the mountains that we use as a getaway as often as possible. Oddly enough, this place is a pretty good location for radio propagation. It sits at 9600 feet in elevation with low electrical noise and a decent radio horizon in most directions.

I’ve been putting up temporary antennas at the cabin for VHF contests, Field Day and the occasional HF contest. I am slowly building the ham station, with high expectations but slow progress. I wanted to get an HF rig to put in the Cabin Shack. Actually, I started out thinking I needed a DC-to-daylight rig so that I could cover all bands in one radio. I had my eye on the new ICOM IC-9100 that was announced back in 2009. I patiently waited for well over a year for this radio to become more than vaporware and they start to show up in the US in early 2011. Unfortunately, the street price turned out to be $3700, which seemed a bit too high to me.

This sent me back to rethinking the whole approach. I have to admit that I had not shopped for an HF rig since I bought my Yaesu FT-847 back in the 1990s. The 847 has been my all-time favorite transceiver based on how the controls are set up and the coverage of HF plus 6M, 2M and 70 cm. My only beef with this rig is that the receiver can get overloaded during heavy band usage (like popular HF contests and Field Day).  I started thinking about getting an HF + 6 Meter rig to complement the FT-847, which would give me two radios during contests. In particular, for VHF contests, I’d leave the new rig on 6 Meters all of the time and jump around 2 Meters and 70 cm with the FT-847. I also wanted the new HF rig to be very solid on HF and include some of the advanced features for DXing and contesting.

Soon I was looking at all of the radios that cover HF through 50 MHz. That’s when I really got sticker shock — the FT-DX9000D costs over $10k, the IC-7800 costs $12.5k, the IC-7700 is $7200, and so forth. All of these radios look like fine gear but I was unwilling to invest that much in a transceiver for the cabin. I quickly redirected my radio hunt to something below $2500, looking at the IC-7410 ($1900), FT-950 ($1350) and TS-2000 ($1575). In the end, I chose the FT-950 due to its price advantage and the ability to share accessories (microphones, mostly) with my FT-847.

I got the radio just in time for Field Day, where I gave it a good work out on 14 MHz, 21 MHz and 50 MHz. Wow, did it work great! The receiver performed very well even when the band was packed. In the heat of the battle, I pushed a wrong button or two and sent the rig off to some new and wonderful frequency. Yes, I did take the time to read the manual but I’ll have to spend some more time with it. This thing has enough features that it will take some time to master it.

Time to Change the Rules for Field Day

Posted on by

I just finished writing about how Field Day can be “seasoned to taste”…adapted to your particular interests. Overall, I think the ARRL has done a good job of crafting Field Day rules that provide some incentives for certain types of operation and activities. Get On the Air (GOTA) station, the free VHF station, and Class F (EOC location) are examples of positive rule changes that have been made over the years.

Still, I think there is room for improvement:

  • Eliminate the point advantage for CW and Digital contacts Why does Field Day have a scoring scheme that favors a particular mode? That is, CW and Digital contacts count 2 points versus 1 point for Phone. If these modes have some kind of efficiency advantage, then let that be the reward.  If not, then why the scoring incentive? The point benefit makes no sense to me, so I would eliminate that 2X advantage.
  • More Points for VHF/UHF Field Day is supposed to be about operating under simulated emergency communications. However, most real life EmComm activity makes heavy use of FM VHF and UHF to get the job done.  I would increase the number of points awarded for contacts on 144 MHz and higher to 2 points per contact, to compensate for the natural shorter range of these frequencies.
  • Remove Restriction on 146.52 MHz Also to encourage VHF operating, I would eliminate the prohibition against using 146.52 MHz. No other calling frequency is restricted in this way.
  • Make the Contest 24 Hours Field Day is set up to run 27 hours as long as you don’t set up at the start of the contest. It seems that must clubs set up early and just operate the first 24 hours. I would just simplify the event and make it 24 hours.
  • Bonus Points for VHF Packet or APRS Modern traffic handling uses digital methods, so I would encourage this by offering 100 bonus points for either establishing a functioning APRS station or packet radio system.
  • Require Electronic Log Submission Come on, this is the 21st Century….paper logs should be eliminated and all logs should be submitted electronically.

Well, my VHF+ tendencies are showing. These are my suggestions—what do you think?

ARRL Field Day: Season to Taste

Posted on by

The 2011 Field Day is over. I have to admit that I am a bit ambivalent about Field Day…I can take it or leave it. But I have always thought that one of the great things about Field Day is that it can be tuned to whatever interests you or your club. It can be a serious radio contest (well, almost); it can be an EmComm Drill, it can be a Radio Campout;  it can be a food fest, it can be a beer-drinking party. Insert your idea here.

Here’s how my Field Day played out this weekend. The plan was to escape to our cabin in the mountains and set up a temporary HF + VHF station powered by a gasoline generator (1 transmitter, Class B). I used a basic trap dipole on 40M/20M/15M, a 6M5X Yagi on 6 Meters and a 2M9 Yagi on 2 Meters. I was hoping for some decent propagation on 20 Meters and 15 Meters, if 6 Meters opened up that would be awesome.

An urgent matter popped up on Saturday which took priority for most of the day. I finally got on the air Saturday evening and was pleasantly surprised to find 15 Meters still open. I worked quite a few stations on 15 M SSB until the band faded, then I slipped over to 20 Meters. Later, I noticed that 6 Meters had some life in it, so I turned my attention to that band, working back into the southeast.

The next morning, I checked 6 Meters and it was open again to the east. I was cranking out the contacts on 6 Meters but occasionally flipped around to the other bands. It was interesting to compare the 6 Meter activity on Field Day to the June VHF QSO Party. The propagation and number of stations on the air were similar. The skill level of the Field Day crowd was noticeably lower, with more dupes and sloppy operating. (That would be Field Day as a training event.)

Band  Mode  QSOs    Pts
 7    LSB      6      6
 14   USB     37     37
 21   USB     92     92
 28   USB      1      1
 50   USB    273    273
 144  USB      3      3
 Total       412    412

As you can see from the score, Field Day turned into a second June VHF contest for me, with 273 QSOs on 6 Meters.

A great time was had by me. How was your Field Day?

The HF Bands Are Back

Posted on by

First, I need to admit that I am an HF slacker. My first love in ham radio has always been VHF and higher and I have always treated HF as something secondary. I am not sure why but if I figure it out, I will let you know.

Lately, my HF antenna (a powerful device that I refer to as The Dipole) has been laying on the ground. It seems the support rope broke months ago and I never found a reason to put the antenna back up. Like I said, I am an HF slacker.

Here’s my idea of having fun on HF: fire up my Yaesu FT-847, belching a mighty 100 Watts into some kind of simple antenna. Get on 20 Meters SSB and higher and work DX stations all over the world. Actually, I don’t like 20 Meters that much because it always seems to be filled with signals. I really, really like it when 15 Meters opens up because the band is big enough to allow lots of signals without that bloated feeling.

This is exactly what happened last weekend for the CQ WPX Contest. I was only able to operate about 4 hours, with the goal of having fun and working some DX. The propagation on 20 Meters and higher was excellent! It’s amazing what a few sunspots can do for propagation. The contest format is pretty cool, too, as everyone works everyone but with an emphasis on picking up callsign prefixes and countries. I made 100 QSOs, mostly on 15 Meters, with all continents and many different countries. That was a blast.

After I loaded my log into Logbook of the World, I got the instant gratification of seeing 27 of those QSOs confirmed this week. Not a bad percentage…with the emphasis on confirmed this week. I am really liking this.

The HF bands are back!
