I let my membership expire after they unilaterally cancelled my paper QST. I'm still mad about that, and the steady trickle of other news doesn't make me want to go back.

 

Three of us (AA6XA, KE6MT, N6RUN) spent a few days peakbagging and playing radio in California's White Mountains. The highlight was climbing White Mountain Peak, a 14er. Here are the videos from the trip

Hope you enjoy!

 

As you've probably heard, the Quansheng UV-K5 is the hot new HT. And there is a good reason it is so popular. I've been having a lot of fun with mine, and I would highly recommend getting one. 2m FM is fun, and 2m SSB or CW is even funner. And if you choose the same firmware to load as I did (uvk5cec), it will transmit APRS and SSTV.

I made a video going over how mine is setup. Hopefully it helps if you have one. And I'm sure there'll be more videos coming with it in use. The CQ VHF contest is just a week away....

Hopefully someone or some other business will buy them. Hate to see them go.

For POTA contacts I'd just fix it.

In a contest that would be cheating.

Some clubs meet in person and on zoom simultaneously, does your local one? I'd get in contact with them anyway, someone might have a loaner rig you can use to get on the air and see what interests you the most.

Parks on the Air and Summits on the Air are popular an a lot of fun, but you'd need a radio first.

With some basic tools you could build your own radio from a kit.

My reading of the state park map is that the park is on the ocean side of route 1, so that'll eliminate going up any real hills. I'm not really familiar with that section of the coast, though.

It also sounds like you want an excuse to expand your antenna collection. Go for it! Antenna experimenting is fun. Set up two, and try some A/B testing, or use WSPR or RBN.

Its an interesting problem you've found. As a frequent SOTA op, its not one I encounter :D

To get NVIS just use your regular 40m antenna, but set it up closer to the ground. Depending on your mast height, it might be NVIS already.

What park is it? Maybe there's a spot off the beach you could operate from?

[–] [email protected] 1 points 10 months ago

I'd get an SSB capable radio unless you're only interested in FSK modes.

 

I made and tested a couple of capacity hats for my loaded whip antenna to see how they'd do in the real world. Could you use one instead of paying Elecraft for their 40m coil? Maybe. Could you get on 30m and 40m with your KH1 whip? Might be a stretch... https://youtu.be/uYH9yit8jEo

A j-pole is a half-wavelength vertical with a quarter-wavelength matching section on the bottom.

It turns out that the 70cm band is about 3x the frequency of the 2m band (150MHz * 3 = 450MHz, close enough to each band). So the 2m the long leg of the j-pole is 3/4 wavelength (1/2 + 1/4 matching section), and on 70cm the long leg is 2.25 wavelength (3/2 + 3/4 matching). Both are an odd number of quarter waves, as we expect. The ham who made that briefing probably discovered in their testing that the matching stub wasn't good for both bands, so they added a second one for 70cm.

This is not a novel design, Arrow Antennas has been selling one like it for years (https://www.arrowantennas.com/osj/j-pole.html)

I'm excited to see the new digital modes people bring to ham radio, or invent.

Every time I go out and play radio, I think of a new reason I really need a KH1.

[–] [email protected] 1 points 1 year ago (1 children)

It's pretty easy to create it if you want it. I've made a few communities 🤷‍♂️

 

I assume by now everyone's heard about the new Elecraft KH1 handheld transceiver. Offical Website Wayne N6KR is not a SOTA op, but he seems to know exactly what SOTA ops want.

I was able to hold one and play around a little at Pacificon today. Definitely a nice radio. Most of the internal volume is a giant battery. Due to space limitations, he said not to expect any other bands. But 40-15 is the sweet spot for QRP HF. Lightweight, and even with the whip extended doesn't feel heavy. Probably the closest thing the ham community has to an HT for HF, so far. I wouldn't mind having one; N6KR is a great salesman and engineer. I'm sure there are videos out showing it in action by now. We timed him going from packed to ready to transmit, it took him about 22 seconds. Most of that time was unwinding and tossing out the counterpoise wire.

The receiver is a superhet, similar to the MTR or KX1. Transmitter puts out 5W. There are two antenna connectors, BNC and the screw for the whip, and you can choose between them. Its not really shown in the manual, but there's a little "catch" to hold the end of the counterpoise wire when it's wrapped around the radio to keep it nice.

This has been my experience using multiple HTs on the same band.

 

The first weekend of the ARRL 10GHz and Up Contest starts tomorrow (August 19) at 0600 local. https://contests.arrl.org/10g/ There will be plenty of activity in California, and probably other regions. It's a fun contest, and everyone should get on the band!

I'll be on a SOTA summit (W6/NC-151) on Saturday, not sure if I'll be able to get out on Sunday.

 

The ARRL 222MHz and up contest is this weekend: http://www.arrl.org/222-mhz-and-up-distance-contest

I'm planning to get on from a summit with the lower four bands. Probably won't be as much activity as the regular VHF contest, but should be fun

 

The KPH coastal station near San Francisco sent a special message this weekend. It was encrypted with an Enigma machine and sent for everyone to try and decode. If you missed it, and want to try I posted a video of it: https://youtu.be/IgbggcpxrC0

Have fun!

 

In case you missed it: (stolen from the ARRL weekly letter)

Summits on the Air (SOTA) in North America has three events scheduled between August 4 - 7, 2023. The Colorado 14er annual event will run from August 4 - 7, the SoCal SOTAFest in Southern California will run from August 4 - 6, and the Pacific Northwest Not-Quite-Fourteener event will run from August 5 - 6, and includes climbers in Washington and Oregon.

Many different frequencies and modes will be used during the August events, but the recommended 2-meter FM frequencies have been changed to 146.58, 146.55, and 146.49 MHz to align with the use of the North America Adventure Frequency for SOTA (146.58 MHz). Operation is also permitted on select HF frequencies. The National Simplex Frequency (146.52 MHz) may also be used. Each event website provides a list of operating frequencies. All amateur radio operators and shortwave listeners are invited to participate.

 

The CQ VHF contest starts soon. Sadly, I'm not able to get on the air, but if you have 6&2 meters you should give it a try. https://cqww-vhf.com/

 

Anyone know a reliable way to have RBN spot you during an activation? My activations are almost always CW.

Most of the POTA I do is during SOTA activationd, and there is not always cell service. And trying while camping in parks is even worse. SOTAwatch has RBNHole which is very reliable if you've put up an alert beforehand. I've been told there is something similar for POTA/WWFF, but it's never worked for me.

Diz W8DIZ has retired from running kitsandparts.com, and KU4QO had taken over.

Good news if you need toroids and other small parts. And the 5watter is a great radio if you need a kit.
