Apache case for the KH1

Many thanks to Tom (WW8D) who writes:

Hey Thomas,

This is Tom WW8D in Salem Va. I sure do enjoy your videos on youtube. I received a new KH1 yesterday and I just wanted to tell you that I have a clear waterproof case like the one you but its a slight bigger fromHarbor Freight. Its an Apache 550 and everything fits perfect in it.

Note from K4SWL:

I purchased the Apache 550 a few days prior to Helene hitting our area. I intend to make a post or video soon showing how this apache case compares size-wise with my Pelican cases. It is, in general, a much larger case than the M40 I currently use with the KH1. See photo below.

VE6LK’s “One CW Question” YouTube Series

My good friend, Vince (VE6LK), came up with a great idea a few weeks ago: reach out to CW ops and ask one question that might help newcomers to Morse Code. Each video is 2-3 minutes long and features a number of ham radio operators who operate CW (I’m chuffed to be one of them).  I’ve learned something from each of these videos.

1296 on the Icom IC-705

Many thanks to Alan who shares this video of VK3FS operating his Icom IC-705 on the 23cm band.

Video description:

If you enjoy SOTA, parks, microwave or radio in the great outdoors, then Icom IC-705 is the radio for you. Having received many accolades, and a long list of positives, some might say there’s one thing missing on the IC-705 and that’s the 23cm band.

The good news – is it’s a relatively easy fix with the help of a 1296 MHz transverter from SG Labs.

Efforts to Rekindle NJQRP Club

Many thanks to Dennis (K2DCD) who shares the following message sent originally by Larry (W2LJ):

Once again, I’ve been giving thought to attempting to pump new life back into the New Jersey QRP Club. For many, many years it was considered to be one of the top QRP organizations in the country. It ranked right up there with the NorCal QRP Club, the Colorado QRP Club, the New England QRP Club and others.

In the early 2000’s, due to the efforts of George N2APB and Joe N2CX and a host of others, the NJQRP Club reached its azimuth when it sponsored Atlanticon, the QRP confab of the Mid-Atlantic Coast. It was held in Baltimore and each year I was dying to go. But my two kids weren’t even really toddlers yet, and with Marianne and I both working full time, it was an impossibility.

Soon after Atlanticon ceased, it seemed the club started to wither away. Stalwarts became Silent Keys, others moved away and NJQRP started to become a shadow of its former self. There were a few times I met with other members at the food court of one of the malls near Princeton. There were also a few outdoor gatherings at the park in Grover’s Mill – the infamous landing spot of the Martians in Orson Well’s “War of the Worlds”. And then finally there was nothing.

So where does that leave us? The website was moved to its present URL location in 2016. As far as I can tell, there have been no updates. And in all honesty, except for the Skeeter Hunt, there hasn’t been much activity to update the webpage with. Whatever the members have been up to individually, there’s been no real effective means of communication between them.

George N2APB has moved to Tennessee and N2CX is a Silent Key. There’s no roster, so there’s really no way to tell who was a member and who was not, and what members if any have either moved out of the area or have become Silent Keys. And since the last iteration of NJQRP, there just may be a whole new generation of New Jersey QRP’ers anxious to meet their like minded brethren in the state.

So we start with a new beginning. I started a Facebook page. As of right now, it’s a public group and I think you can just join. I’ve also started a Groups.io group now that Yahoo groups are defunct. This group will be an e-mail reflector and our main way of keeping in touch with each other. If you’d like to join that, you’ll have to send me an e-mail ([email protected]) and I’ll send you an invitation to join.

Granted, it’s not much of a start, but it is a beginning. Hopefully, as the word spreads and QRPers in New Jersey and the surrounding area become interested, maybe we can start holding meetings, if we can find a location that is convenient for all.

I’d like to stress that while the New Jersey QRP Club will primarily serve local QRPers as far as any future live in person events go, there are no residency requirements. All are welcome and if we do meet in person, we can always incorporate a Zoom component as other clubs I belong to have been doing to include those who can’t attend in person for whatever reason.

It’s not my job to run the organization, that will be up to the members. I’m just going to try and re-launch it. So stay tuned – maybe we can light this candle and get this puppy off the ground!

QRPer Notes: Phil’s Field Antenna Survey Results, Gripping the Palm Pico, and 70’s/80’s Vintage QRP Radios

Field Antenna Survey

Many thanks to Phil (KA4KOE) who shares the results from an informal survey he conducted on the POTA Facebook group. Phil writes:

Tom

I’ve let the survey run for about 3 days on the POTA Facebook group. Sample size was 658 votes. I opted to do a “type” survey and not by manufacturer.

Results:

    1. End Fed Half-wave: 25%.
    2. Shortened vertical with loading coil: 20%.
    3. Full-size vertical antenna / Hamstick style vertical with helical coil:12% each.
    4. Full-size dipole/doublet, etc.: 10%.
    5. End Fed Random Wire: 9%.
    6. Screwdriver motorized coil antenna: 3%
    7. Something tossed in tree and just hoped it would work: 2%

Total: 93%.

Remaining obscure types cut-off below 2% accounted for 7%.

Again, like the poll I conducted previously on radio types, not surprised by the No. 1 spot.

What DID surprise me was #7: I put that selection in the poll types as a joke but 2% of hams throw a wire up in a tree or other support with no forethought and hope it works.


The Palm Pico: Getting a grip!

Many thanks to Terry (N7TB) who shares the following tip:

Hi Thomas,

I was looking at your post re: the Pico Paddle.

I have both the single and double Pico paddle and the KX3 mount. After watching you hand hold your paddles, I came up with a way to make small paddles easier to hold. I have attached a photo. It is a small piece of 3/8 ID pipe insulation to make holding the Pico paddle easier.

Have a great trip to Hamvention.

73,

The Ailunce HS2 has lots of potential (KB6NU)

Just before Thanksgiving, I received an email from Cara Chen at Retevis. She wrote,

I am responsible for the radio review cooperation. We have a SDR radio HS2 for review cooperation. Are you willing to test and write a blog about it?

When I asked her what that meant, she said that she would send me an Ailunce HS2 SDR Radio, if I would review it here on my blog. When I told her that I would be brutally honest in my review, she seemed OK with that and sent me the radio.

What follows is an honest review. It’s not a QST-style review. I don’t have the test equipment that they do, nor did I have the time to put the radio through all its paces. Even so, I did operate the radio on HF and VHF, phone and CW, enough to make the review worth reading, I think.

If you don’t want to read the rest of this review, I can sum it up as follows: The Ailunce HS2 is a fun, little radio, with lots of potential. It’s not perfect, though. The buttons are too small, the display is too small, and the manual needs work. More about all those below.

What’s in the box?

As you can see below, the radio came with a handheld microphone, a DC power cord, and a USB cable.

First impressions:

  • It’s really small. It’s 45 mm H x 120 mm W x 190 mm D (1.77 in H x 4.72 in W x 7.5 in D)
  • The carrying case is kind of nifty. If you’re going to operate portable, it’s nice to have.
  • The extruded metal case include a nice heat sink.
  • There are a lot of connectors on the rear panel, including the power connector, an SO-239 for HF and VHF antennas, an SMA for a GPS antenna, two USB connectors, an Ethernet connector, and four 3 mm phone jacks.

New CW YouTube Channels/Videos

In the past two weeks I’ve received a number of video links from QRPer readers who are featuring CW activations in their YouTube videos.

First up is Steve (K9NUD) who has started a new channel featuring his CW activations primarily using a cootie/sideswiper. Steve is doing something I wish I had the time to do which is add CW closed captions to his videos. This makes it easy to follow along. Check out this video:

Jonathan (KM4CFT) recently noted in the comments of my YouTube channel that he made a video of his third ever CW POTA activation. I had to check it out and am glad I did. You get a very good idea of what it’s like on the air as a CW newbie. In other words: not that bad at all! Incidentally, when I looked up Jonathan on QRZ, I discovered we have a mutual friend in Zach (KM4BLG).

Keep up the great work, Jonathan!

Chris (KD2YDN) sent me a link to the following video on his new YouTube channel. In the video I actually get to hear what my signal sounded like during his SOTA/POTA activation. He certainly captured some amazing morning scenery and a gorgeous sunrise from Westkill Mountain:

I think you should consider checking out these videos and subscribing!


The ARRL Handbook 100th Edition

The ARRL has announced pre-orders for their new ARRL Handbook. I feel like everyone should have a copy of the Handbook. It’s simply chock-full of useful information–much of which is simply timeless. I still reference the 1994 handbook my buddy Mike (K8RAT) gave me shortly after I got my license in 1997. I feel like it’s important to have reference material like this in paper.

As a side note, I’ve been to a number of shortwave radio broadcast transmitting stations and at each one of them I’ve seen the ARRL Handbook on the Chief Engineer’s shelf. Lots of great radio principles inside.

The book is $80 on pre-order. That’s a lot for a book, but it’s also a LOT of book!

Here’s the announcement from the ARRL:

We have arrived at a milestone. The 100th edition of The ARRL Handbook for Radio Communications is here: Handbook 100. How do you celebrate the most widely used one-stop reference and guide to radio technology principles and practices?
