KC0YQF activates SOTA Summit W0C/FR-135

This is a quick one. With the weather outside I decided to do a video featuring the XYL as she did a great job activating W0C/FR-135 this weekend.

My Buddipole Vertical

Surprisingly I get a lot of questions about the Buddipole vertical setup I use. I did not buy a standard antenna setup but rather purchased the parts to make what I wanted to meet my specific needs.

We have a deluxe Buddipole for our deployable HF station at work but I started using Buddipole products when I had a truck camper and they just fit well. At the time I did not need to setup and teardown quickly but did need a good antenna system and they performed that task well. As I started down the Summits On The Air path I wanted something I could setup anywhere quickly and that is how I came up with what I use.

I do not use the Buddipole system all the time but sometimes, when space is limited it is easier than running a random wire, especially with many people about, (think Pikes Peak).

I do not do "how to" videos as they take a lot of time to put together correctly so I just used the video from our recent SOTA activation on an unnamed summit called 10,808 for its altitude near the historic town of Victor Colorado.

I have no connection with Buddipole other than giving them money in order to play with their antennas and parts.

Mount Herman, the hard way

The road to access the TH to Mount Herman is closed and the sign says it will be closed until 2 Jan 2015. Mount Herman is somewhat of a SOTA testbed in that it is close by and fun to hike and a great place to try out new equipment for portable work.

My good friend Steve asked me if I wanted to try an approach from the East side of Mount Herman. I always wanted to do that but have never really research the route but just looking at Mount Herman from the East and it looks like a tough one. Of course I said YES!

I took Friday off and Steve and I headed to the TH and off we went. It was steep, about 1700 feet in .9 miles. Wow! It was a real workout.

Besides doing a SOTA activation with Steve there were two other reasons to make this one a special activation. Steve took his LNR made FX-4 radio along and his new goat Boo came along with Peanut.

Boo is a young goat and very curious. He is not shy like Peanut so it made for a very interesting day.

Our route took us North of Mount Herman and South of Raspberry Mountain. I am not sure how long it took us to get to the summit (I would guess about 2 hours) but it was a nice, well marked trail.

Just before it starts to get vertical there is a memorial to a young man that died somewhere on Mount Herman not too long ago.

In memory of Alan Sauceda (I think, not sure if I am reading that correctly)
Peanut is always great on the trail. Sometimes you just forget Peanut is there but he always is. Boo is also an easy going hiker but he did give me an occasional push on the way down as I was holding him up. Boo, like Peanut and Rooster before him, follows Steve everywhere he goes. They really are great hiking companions.

When we summited we found a spot out of the wind, which was keeping it very cool, and Steve got to work throwing the random wire into a tree. The random wire was tuned with an Elecraft T1 connected tot he LNR FX-4.

Here is the video of the activation:

The FX-4 is a first generation one which was recalled by LNR for a replacement/refund/repair or something to that effect. Kudos for LNR buying up all the faulty units.

There has been another run/release of the FX-4 but I was not able to get one. I really did not have a lot of time with this radio to tell much about it. It is not a KX3 but then again it is less than half the cost moreover, it is even cheaper than a FT-817. I think it is a good radio for those that do not want to build something and want to get on the air in portable fashion using SSB. It would take a little bit to get used to the menus but the limited exposure I had I could tell the menu was easier to learn than the FT-817. It is also lighter and more compact than the FT-817. I think the power consumption is about the same (not saying much as the FT-817 is a power hog). Maybe the second run improved that but I do not know that for a fact. I did feel like I had to yell into the mic to get the ALC going, very much like a FT-817.

As far as performance I would say the receiver is better than a FT-817 but not as good as an Elecraft KX3, I realize that is about a wide a margin as they come. The filters seemed to work great. I did not play with the delay but it was a little too long for CW as I was missing the call sign prefix of some of the quicker stations after a CQ. All in all I liked it and would consider one if they make them again which I doubt they will since they already released a new SDR radio that I am sure will take up time and resources.

The LNR FX-4 and their new radio is a good alternative for the SSB operator that does not want to settle for a FT-817 (and all the performance modifications to make it viable) and something cheaper than the KX3 with less capabilities. It is worth considering.

The McNeil / Swisher Trail to Cheyenne Mountain

The McNeil Swisher Trail does not really go to the summit of Cheyenne Mountain but it gets you about a half mile away. The McNeil part of the trail is well marked and actually goes down in elevation at first so it is a little tough coming back up if you did the Swisher Trail. The Swisher Trail has several switchbacks and is a bear but is not that long. Once you get to the top you come up at an Aspen Grove and you follow it around to the West and South and make your way up the slope to the ridge that the Cheyenne Mountain geographical summit sits on.

Here is the actual trail.

Lynn and I had lunch just beyond the Aspen Grove and enjoyed the views and mild weather then headed back down.

Here is our route:

Our usual route to the summit of Cheyenne Mountain for a SOTA activation would be almost straight on (East front he same TH) and very vertical. This is a much longer route (around 6 miles roundtrip). Lynn and I did close to 5.5 miles on this trip. I want to explore this area a little more either before the snow starts in or next spring.

While on the summit I sent an APRS email to my friend Mark, WA6MVT, and to myself and it worked fine. I did talk to K0NR briefly on two meter simplex on our way down but copy was rough so we cut it short.

Some APRS testing on Mount Herman

I have recently become interested in utilizing APRS and all the functionality of my APRS capable radio, the Kenwood TH-D72. This came about because too many times I have been unable to spot Lynn on SSB via the cell phone SMS service and sometimes the chasers will not spot her either so using APRS just gives us one more avenue to get her spotted so she can have a pileup of SOTA chasers and give out as many points as possible. On CW it is much easier since Reverse Beacon Network will pickup the CW signal and put the spot out there as long as an alert is posted.

I made up a checklist and used it to great success.

Here it is:
Kenwood TH-D72 Checklist

Sending APRS message to self spot or to another Amateur APRS radio:
-       Press “f” (f = function key) then MSG Key or number 4
-       Enter callsign( i.e. SOTA / K0JQZ / NK0E / etc) press “OK” twice
-       Enter text (for SOTA SPOT enter “W0C/FR-063  14.061  CW K0JQZ CQ” (in bold is required information)
-       Press OK to send

Sending email:
-       Press “MSG” Key
-       Select Menu
-       Select NEW
-       Enter “EMAIL” in the TO field
-       Enter email address and leave one space blank after email address
-       Enter email text
-       Press OK to send

The hike was nice with the threat of a storm the whole way.

Here is a video of the activation.
