I noticed that I’ve been blogging mostly about SOTA activations, so here’s something completely different: a bunch of exciting stuff flowing forth from the interwebz.

From the Why Do They Do That Department, Jeff/VA2SS shared this article on the origin of the radio term “Roger That.”  See The story of why pilots say “Roger that”

This reminds me of the classic scene from the movie Airplane, with the flight crew named Roger, Victor and Clarence.

I recently came across the Wikipedia web page on Etymology of Ham Radio, which explains the origin of the term “ham radio.”  Etymology: the origin of a word and the historical development of its meaning. About the same time, Dan/KB6NU wrote about the use of the term “ham radio”: HAM? HAM radio? ham radio? Amateur Radio? amateur radio! I have to admit that I do get annoyed by people that write “HAM” in all caps. What the heck is that?

The ARRL recently published a series of six posters promoting the value of amateur radio. I’m not quite sure where to deploy these but I do like them.

I was checking on electrical voltages and plugs in various countries and came across this site: Power Plugs and Sockets of the World  Very handy and easy to use.

Twitter was abuzz with news about a new VHF/UHF transceiver from ICOM: the IC-9700. This is the first new radio aimed at VHF and up enthusiasts in a long while. I try to not get excited about these early product teasers and wait until the product is shipping in quantity. But I have to admit that this radio has my attention. I don’t have a lot of Icom gear in the shack but this radio may change that.

The DX Engineering web site shows these key features for this unreleased product:

Direct-Sampling SDR design
Three bands: 144 and 432 MHz (50 Watts), 1.2 GHz (10 Watts)
High definition Real-Time TFT display
Main and Sub RX
Dual Real-Time Spectrum and Waterfall displays
Dual Watch (with Spectrum/Waterfall displays)
Touchscreen interface (LCD touch-screen control)

That’s some good stuff spewing from the internet. What did I miss?

Judy and I rode our bikes along the Pemigewasset River today. It was a beautiful, beautiful day. I worked Bulgaria, Italy, Switzerland, and Hungary.

We rode south from Old Hill and stopped at the old bridge to Sanbornton. It was nearly 80F with an unbelievable stillness in the air. Brown, curled-up leaves covered parts of the old road and crunched beneath our bike wheels. The apple trees along the way have begun dropping fruit. Judy stopped to pick up some apples. The road was lined with asters.

I stopped at a huge pine tree a couple of miles down the road. I tossed my wire nearly 40 feet over a branch and sat on some moss. I used the KX3 and a 33 foot wire.

The bands were good. I worked eight stations. Here’s my log:

Today was a perfect day for getting outside and making a few radio contacts. At this time of year, I can count the days like this on one hand. I wish they would never end.

Judy and I hiked up Rattlesnake Mountain overlooking Squam Lake this afternoon. It was gorgeous! And… I worked St. Pierre and Miquelon, Belgium and Florida.

The hike is pretty simple… about 40 minutes. Huge rock ledges cap the peak at about 500 feet above the lake. It was sunny and about 72F. A perfect day for an outing.

I set up on a northern ledge and tossed my line into a stubby pine tree that was about 25 feet above the rock. I had a sloper.

I started out on 30 meters and heard FP/G3ZAY on St. Pierre and Miquelon. These two French islands sit off the coast of Newfoundland… a favorite for small dxpeditions. I was thrilled to work them from Rattlesnake Mtn. because I’d been trying unsuccessfully for a couple of days from home. We exchanged quick 599s and I switched to 20 meters.

As I tuned across the band I heard Bernie KB4JR calling CQ from Florida. He gave me a 559 and we chatted for a few minutes before signing. A little farther down the band John ON4UN was calling CQ from Belgium. He was strong as always and we had a quick exchange. I told him I was QRP on a mountain top and he wished me well.

Judy and I had a snack before packing up. Judy got a quick photo as I enjoyed the view a final time before heading down.

Kaufman Ridge is a ridge line that runs along the border of Park and Chaffee Counties in Colorado, near Trout Creek Pass. There are two Summits On The Air (SOTA) summits on this ridge: Kaufman Ridge (W0C/SP-081), formerly Kaufman Ridge HP, and North Kaufman Ridge (W0C/SP-085), formerly Kaufman Ridge North. I have activated these summits before including a winter activation of North Kaufman Ridge. These summits have turned out to be popular SOTA activations because they are easy to access, easy to hike and have outstanding views of the surrounding area.

Joyce/K0JJW and I decided to do a SOTA activation on a pleasant September day. On previous trips, we approached the summit from the east without much thought to the route. This time we approached from the north, based on a tip from other SOTA activators. This route is a little bit longer than coming from the east but it turned out to have fewer steep spots and less downed timber to navigate.

To get to the start of the hike, we went south on Windmill Drive to FS 318, entering the San Isabel National Forest. There is a gate at the entrance to the forest that is closed from December to April. We turned right onto FS329, which may not be marked but is an obvious 4WD road heading to the north. We drove to the end of the road and parked near the National Forest boundary. These are really easy 4WD roads such that a high-clearance 2WD vehicle should have no problem.

At this point, we aimed straight at the summit and started hiking. We found only bits and pieces of a trail here and there. Someone has attempted to mark the trail in places but it was difficult to follow. No worries though as the route was relatively smooth without many obstacles such as rock formations and difficult downed timber. We had to do some minor route finding but just looking ahead for obstacles was sufficient. The one-way distance was 1.1 miles with a vertical gain of 800 feet.

On top, we both snagged plenty of radio contacts on VHF/UHF and enjoyed the excellent views in all directions.  This made for a nice SOTA activation on a sunny fall day!
