I find it extremely odd that OFCOM has granted access to an additional 1MHz of VHF when the existing 144-146MHz band is grossly under-occupied most of the time. Take a listen 144-146MHz in YOUR area in the UK or elsewhere in Europe. Mostly you will hear white noise!

This is only ad interim, only by NoV to full licence holders, and only in some areas. It is clearly a sop for messing with the microwave allocations. It is very unlikely much new (to radio science) will be gained by this 1MHz allocation. MUCH more would have been learned by a 100kHz allocation around 40 or 60MHz or by allowing UK amateurs free access below 8.3kHz or back onto the withdrawn 73kHz band.

I know it is heresy to say “no, I am not interested” but OFCOM could have done so much better and it has lost credibility in my eyes as a result. I cannot believe allocating this spectrum to radio amateurs serves any useful purpose at all. The RSGB talks about digital TV etc. Sorry, this is rubbish: it is hard enough getting anyone on digital TV on 432MHz and 1296MHz where most ATV activity takes place! I can see perhaps a small handful of people forcing themselves to use this band. On 40MHz, the Es possibilities would have been wonderful.

No, in my humble opinion OFCOM should not have given radio amateurs this band at all. It would really have advanced radio science if they had allocated new, smaller, bands at more interesting places in the spectrum. Let us at least hope OFCOM supports moves internationally to a contiguous new amateur band at 5MHz (60m) at WRC2015 next year. This will be useful in the quieter years to come.

It was a nice fall day, so Joyce K0JJW and I decided to go for an easy hike up Kaufman Ridge HP (W0C/SP-081) and do some SOTA operating. Well, maybe the hike was her idea and the Summits On The Air thing was my contribution to the plan. The hike is less than a mile and has about 900 feet in elevation gain, depending on where you start the hike.

This definitely a slacker operation: easy access, easy hike, great weather and 2m FM activation via a handheld radio and the 1/2-wave whip.

Note that there are two SOTA peaks with the “Kaufman Ridge” name: Kaufman Ridge North (W0C/SP-085) and Kaufman Ridge HP (W0C/SP-081), located near Trout Creek Pass in Colorado. Today we headed to SP-081 which we reached by following County Road 318 from Trout Creek Pass, which is also called Buckrake Drive and then Windmill Drive. These roads pass through private property to reach the San Isabel National Forest, where there is a gate that closed from December to April (see map). At this point, the road is easy 4WD, most 2WD high clearance vehicles will do fine. You can also approach from the south on FS 308 through Mushroom Gulch. 

We turned left onto FS 308 and then took a short side road FS 308B toward the summit. There are several over turn offs but 308B seems the best (shown in black on map). The road is blocked for vehicular traffic at 38.858659° N / 105.933921°W. You can continue walking on the road a ways or just head straight for the summit. While the hike is short and not that steep, there are plenty of downed logs to give you a challenge.

You never know who is going to show up on 146.52 MHz in the mountains but I had put the word out via email to some of the local hams to let them know I was doing a SOTA activation. When I got to the summit, I had a few stations already calling me and I quickly worked Ron N0MQJ, Fred N0VXE, Dave K0HTX, Jim KD0MRC, Bob W0BV and Don K0DRJ. Don was my “best DX”, about 60 miles away in Woodland Park with a few mountains in the way. Thanks to everyone that came on frequency and contacted me.

Side note: if you want to activate SP-085, go north on a forest service road (not shown on map) near where 318 and 308 intersect. Just drive a short ways north, find a parking spot and bushwack your way up the summit. You could easily activate both summits in one day.

The post SOTA Activation: Kaufman Ridge HP (W0C/SP-081) appeared first on The KØNR Radio Site.

The North America SOTA Weekend coincided with the ARRL September VHF Contest, which I interpreted as a great opportunity to do a combination SOTA activation and QRP VHF operation. A few other folks thought that was a good idea so we all got on the air from SOTA peaks on the Sunday of the weekend. I decided to operate from Mount Herman (W0C/FR-063) in grid DM79. I hiked up the same mountain for last year’s September contest and got soaked by the rain. Fortunately, the weather was excellent this year, making it a great day.

View from the south side of Mt Herman

For radio equipment, I took a couple of HTs for 2m and 70 cm FM and the FT-817 for CW/SSB on 6m, 2m and 70 cm. Most of the SOTA action would be on 2m FM but SSB is critical for working the VHF contest. I did put out the word to the usual VHF contesters that there would be FM activity and did work a few of them via 2m FM. The 2m FM calling frequency, 146.52 MHz, is commonly used for SOTA but is not allowed for contest use. (Another example of how this rule is just a barrier to contest activity.) We used 146.55 MHz for the contest contacts. I had coordinated with Brad WA6MM who was going to be on Grays Peak (W0C/FR-002), one of the Colorado 14ers. When he made the summit, I had my 2m yagi antenna pointed in his direction and easily worked him on 2m FM at a distance of 65 miles.  Brad was using an HT with a 1/2-wave vertical antenna. Also, I worked Stu W0STU and Dan N0OLD on Bald Mountain (W0C/FR-093) , which sits on the east side of I-25 right at Monument Hill. Contest activity was light, as usual for the September contest in Colorado. We did have two rover stations that activated a few of the unpopulated grids in eastern Colorado: George AB0YM and Jonesy W3DHJ.

Band       QSOs X pt =  QSO pts.  X   Grids   =     Points
 -----------------------------------------------------------
 50         8      1      8             5             40
 144        23     1      23            5             115
 432        14     2      28            3             84
 -----------------------------------------------------------
 TOTALS     45            59            13            767

My contest score was not bad for a few hours of operating QRP portable. It turns out that I had set the Colorado section record for “single-op portable” back in 1990 with just 624 points (using my old callsign KB0CY). Oddly enough, 24 years later it appears that I set a new record. (This speaks more to the lack of QRP activity during the September contest and less about my incredible operating ability.)

All in all, it was a great day in the mountains to take a hike and play with radios. I will probably do the SOTA + VHF Contest activation again.

Over here in G (or M or 2) land echolink nodes need to have permissions from the grown ups. So I’ve sought permission from Ofcom, with the help of the RSGB. I applied for an MB7 node, which means it is can be unattended. In order to do this I needed a minimum of 4 people who are key holders so the node can be shut down quickly. Sounds reasonable? Sounds a bit British to me. Belt and braces and some more belts just for luck.

The node will hopefully be on 2m and I have been told that if it gets granted then I could expect around 2w ERP. I don’t want to sound selfish but I have only heard 2m simplex used in this area for the local net and once in a blue moon Dent gets activated by a SOTA or WOTA chap(ess). VHF in general is scarcely used and its a shame.  UKAC evenings and the normally quiet repeaters with their occasional skeds excepting mean that both 2m and 70cms are dead.

What can be done about it?

Making it appealing to use, perhaps? A bit of activity always helps.

Internet link may give some users an opportunity not only with existing amateurs but could make it appealing to those on the periphery of the hobby. Makers for example.

Anyway, let the waiting begin and we’ll see where we get to with Ofcom

For truly portable mountaintop all-mode VHF operating, especially SOTA and VHF contests, the Yaesu FT-817ND has been my rig of choice. You might say that it is really the “only game in town” for a 6m/2m/70cm radio that fits in a backpack.

The Yaesu FT-817ND

I’ve had my eye on the Elecraft KX3 transceiver ever since it was introduced, but really I have been waiting for the 2m module to become available. (The KX3 has HF plus 6m standard.) After being announced over a year ago, the 2m module is now shipping and radio amateurs are getting their hands on the unit.

I do enjoy getting on the HF bands but my radio passion has always been centered on 50 MHz and higher. For my purposes, the manufacturers could have left off the HF bands and just designed a portable rig that does 6m, 2m and 70 cm (and maybe 1.25m, too). Or how about a dualband HT that does SSB?

The Elecraft KX3

I’ve used my 817 for many portable operations, so I have quite a bit of stick time on that rig. I’ve not really used a KX3, other than to play with it at hamfests. I’ve also talked with a number of KX3 owners that really like the rig. I was a bit surprised that the KX3 power is only 2.5W minimum (3W typical), compared to 5W with the FT-817. (Yeah, I know, that’s only 3 dB difference, blah, blah, blah.) One of the big complaints on the 817 is that it is a bit of a battery hog on receive (450 mA) but the KX3 is not that much better at 300 to 350 mA. Here’s my comparison table for the two radios — with the emphasis on VHF operation.

The price comparison is a bit tricky because the KX3 can be purchased in kit form for $100 less. Many hams will actually see the kit assembly as a plus, since they get the satisfaction of building their own radio. A microphone is not standard on the KX3, so I added that to the list. Also, there are several different variations on the 2m module, depending on whether the automatic antenna tuner for HF is installed and whether the factory installs the option. I just picked a price that was in middle of the range.

The table would lead you to conclude that the FT-817ND is the clear winner mostly based on price (and the 70cm band). But its not that simple. There is a lot to like about the KX3, including the nice big display and the trail friendly layout. It also has more features for CW, PSK31 and RTTY.

For me, the answer is clear: keep on keepin’ on with the 817, since there is not enough of an advantage to go to the KX3. But I will probably keep lusting after it anyway. This also raises the question: what does Yaesu have coming to replace the aging 817?

What do you think?

Joyce KØJJW and I were headed to the Duke City Hamfest in Albuquerque when we decided to make a side trip up Sandia Crest for a low overhead (read: slacker) Summits On The Air (SOTA) activation.

The view of the summit when approaching via the Sandia Crest Road.

Sandia Crest pokes up 10,678 feet, towering over Albuquerque at roughly 5000 feet. Although the weather was rainy, we enjoyed the drive up the paved Sandia Crest Road through the Cibola National Forest. This looks like a great area to explore and we’ll probably be back sometime in the future.

At the parking lot, about 40 vertical feet below the summit, we paid the $3 per day use fee (self-service USFS station), grabbed the radio gear and headed up the walkway to the top. There is a gift shop and restaurant at the south end of the parking lot, along with several hiking trails. A large radio site on the north end of the parking lot has numerous towers and high power transmitters. The field strength is so strong that a sign has been placed there to warn of radio interference to car alarms and keyless remotes.

There is a large radio site with powerful transmitters near the summit.

I pulled out the trusty Yaesu FT-60 handheld transceiver with the MJF-1714 1/2-wave antenna for 2 meters. I gave a few calls on 146.52 MHz and heard no replies. I am thinking, “surely with so many hams in town for the hamfest, someone is listening on five two.” Joyce was standing next to me with her FT-60 and a rubber duck antenna. We noticed that her radio was hearing signals that I could not hear.

Well, this sign did warn me of radio interference.

Hmmm, the radio with the better antenna is not able to hear anything but the radio with a crummy rubber duck is working fine. At this point, I realized that my HT was being overloaded from the transmitter site with my high-efficiency antenna doing a great job of coupling those signals into my radio. I had to chuckle about this since I’ve often pointed out the poor performance of your typical rubber duck antenna. In this case, the less effective antenna was doing us the favor of reducing interference.

I swapped antennas and began making calls on 2m fm with the rubber duck. I also moved further away from the radio site to reduce the signal level. Yep, now I heard some guys coming back to me on 146.52 MHz. I could tell there was still some interference but it was workable. In short order, I had these stations in the log: KE7WOD, W5AOX, K5LXP, WB5QXD and K0JJW (after moving downhill outside of the activation zone),. Thanks for the QSOs!

I will admit that NM5SW mentioned the interference problems on this peak, so I had fair warning. Keep in mind that the FT-60 has reasonably good intermod performance, probably better than your average HT, and was getting completely blocked with the long antenna. I was glad that I was not using one of the Baofeng HTs. It made me wonder how well my FT-817 would do under the same conditions, but that will be a test for another day.

This sign shows the trail system at the summit and the location of the tram.

Another way to ascend the peak is via the Sandia Peak Tramway, which comes up from the Albuquerque side. We came across this sign that shows the trail system near the summit and indicates the top of the tram (click to expand). The tram drops passengers off some distance from the actual summit, so you’ll have about a 1.5 mile hike to the summit.

In summary, it was a successful activation although the weather could have been better. The big thing I learned was that a more efficient antenna is not always the best antenna. Sometimes a crummy rubber duck does better!

P.S. I later heard from Mike KD5KC that the Kiwanis Cabin (shown on the map) is a good place to operate from without radio interference issues on HF and VHF.

For the 2014 Colorado 14er Event, Joyce K0JJW and I decided to try a summit close to our cabin near Trout Creek Pass. The basic idea was to activate a non-14er SOTA peak with good VHF paths to all of the Colorado mountains. We also wanted to demonstrate the idea of activating Summits On The Air peaks during the 14er event.

SOTA summit W0C/SP-042

We chose an unnamed peak (W0C/SP-042) that rises to 12,792 feet near Cottonwood Pass . This summit was already on my list of SOTA peaks to activate, so that was another plus. The trail starts at Cottonwood Pass, right on the continental divide and runs along the divide for about 2 miles.

Joyce (K0JJW) at the trail head, Cottonwood Pass.

In fact, we followed the Continental Divide Trail (CTD) to get to this SOTA peak. I’ve done several backpack trips on the CTD and its always a blast to be walking along the top of the continent enjoying the awesome views.

The trail starts at Cottonwood Pass and runs along the Continental Divide.

The main trail passes over the top of another summit at 12,400 feet before continuing on to SP-042. The trail does not go to the top of SP-042, passing it on the east side. We just stayed on the trail until we were due east of the summit, then climbed up the east side which turned out to be a bit steeper than it looked. On the way down, we left the summit by following the ridge a bit to the south and found a gentler route back to the trail. Also on the way back, we followed a side trail to the east of the 12,400 foot summit, saving some vertical gain and loss. My GPS app on the iPhone logged the one-way distance as 2.2 miles (including going over the first summit). It looks shorter on the map but the switchbacks add some distance.

After we reached the summit around 9 am, I quickly assembled the 2m/70cm Arrow antenna and mounted it on my hiking stick. Once I had the FT-817 up and running, I spotted myself on Sotawatch.org using the SOTA Goat app. Logging was done with HamLog on my iPhone.

Typical trail conditions on the CTD.

I worked a number of mountaintop stations on 2m fm (147.42 and adjacent simplex frequencies) with the best DX being N4MMI on Redcloud Peak, about 80 miles away. I tried calling on 2m and 70 cm SSB without any luck. Joyce made a few contacts on 446.0 MHz using an HT with a vertical antenna.

Bob (K0NR) pointing the 2m yagi (vertically polarized) for maximum signal strength.

The weather cooperated all morning with mostly white fluffy clouds. We stayed on the summit until noon and then hit the trail back to the pass. This hike is now one of our favorites, really good for visitors that want a taste of hiking above treeline with great views.
