KMTS Summer Test Transmission August 1, 2021

Many thanks to SWLing Post contributor, Fastburstradio23, who shares the following announcement:

Beaming to you from the transmitter’s location, forget summer vacation, it’s time for summer school. Get your pencils sharpened and thinking caps on for the KMTS Summer Test (transmission)! Numbers, poetry, the science of strange tones, music and mountaineering are all part of the curriculum.

And if you are one of those cats who was too hip for school the first time around, we understand. We’ve been there! When you use one of our proprietary quantum radios passing is as easy and pleasant as a breeze blown in from a deserted tropical island. All the answers tp all the questions are right in some reality or timeline!

And after you’ve peaked out with us at the crown of KMTS, you can join us for a Mai Tai at the Tiki bar on top of the mountain as we go over the summer test results.

Thanks for the tip, Fastburstradio23!

As a bonus, I was also sent this video of KMRT’s broadcast from February 2021:

Relighting an authentic Apollo DSKY screen

Many thanks to SWLing Post contributor, Dave (N9EWO), who writes:

A current YouTube Video I accidentally came across. Ever wonder about those digital displays used in the Apollo space missions ? What were they ? Actually it’s quite a story how these Raytheon displays were developed. One has to remember we are talking about the mid 1960’s here and before the days of LED’s. Reminds me of the electro luminance nightlights still sold today.

Many thanks for sharing this, Dave. Being a massive fan of all things Apollo era, I love the deep dive into this crucial, yet very basic computer. The screen looks (and sounds!) amazing.

Recommendations for an HF/VHF/UHF station in an apartment or flat

30 Replies

Many thanks to SWLing Post contributor, Jamie, who writes:

Hi,

I would like to ask a few questions about what would be a good set up for my situation.

I am in a 2 storey property, which is not owned by me (renting via community/public housing), located in a large city in Australia. I currently have an SDRPlay RSP2, along with standalone AM/FM tuners – Sony XDR-F1HD and Onkyo T4970. The computer and all radios are upstairs at the back in a room that is not attached.

Given renting would limit what I can do, what would be best for me to get. For MW and SW frequencies, I am trying to decide between the MLA30+ or the AOR LA400. For above 30MHz (6m, 2m, broadcast FM etc) I am deciding between the AOR SA7000 or a Discone.

I have been told that putting antennas in the roof space is not recommended. Would they work fine in the room near a window? I should mention, I do have a 50ft end fed longwire with 9:1 balun, that has been in storage and never used.

I am also looking at upgrading my receiver. Trying to choose between the WinRadio WR-G305e or the Icom IC-R8600 (would also get the RS-R8600 CD software for computer controlling the receiver). How do the specs compare between these two?

Thanks for your time, and hope that wasn’t too many questions.

Regards,

Jamie

Thank you for your inquiry, Jamie, and I hope you don’t mind, but I’m sharing this message as a post as we have readers who are in the same type of living situation and listening environment. In addition, I believe owners of the gear you’ve mentioned might be able to offer some helpful advice!

I can tell you that you’re correct: in general, antennas want to be near windows or, better yet, outdoors. Even placing an antenna on a balcony can make a big difference in terms of lowering the noise floor. This is less an issue with VHF/UHF, but those antennas also benefit from being outside since there’ll be less attenuation from obstructions.

For HF, I would personally suggest you check out the MLA-30 loop first since it’s such a modest investment and is fairly flexible in terms of how you can configure it. I’m sure our regular contributor, Grayhat, will have some helpful advice as he’s a bit of an expert with urban HF antennas.

Also, the IC-R8600 is a brilliant wideband receiver. Depending on what you wish to have for frequency coverage, I would also suggest you check out the Icom IC-705 transceiver (noting that its RX coverage is not as comprehensive as that of the IC-R-8600).

Post readers: Please feel free to comment with some suggestions for Jamie, especially if you have experience with urban radio listening.

Photos from the 2021 WCARS Hamfest

3 Replies

This past weekend (July 24, 2021), my buddy Vlado (N3CZ) and I attended the 2021 Western Carolina Amateur Radio Society (WCARS) hamfest in Waynesville, North Carolina.

Due to Covid-19 lock-downs and social distancing, this was the first hamfest we’d attended in 18 months. I think all of us were having serious hamfest withdrawal, so this regional hamfest was very well-attended. Who knows what will happen in the future with regards to Covid–numbers are climbing sharply again here in NC–so I think many of us were there enjoying everything “while the gettin’ was good.” It helped that even the indoor area is incredibly spacious and had a constant airflow.

It was so great seeing so many friends, readers, and subscribers. Thank you for stopping by our tables.

This Noyce Joyce radio kit features IN-17 Nixie Tubes

12 Replies

Many thanks to SWLing Post contributor, Jeff McMahon, who shares a link to a Nixie Tube radio kit via the retailer Shop Simo. We’ve no clue how well the radio might perform, but it covers AM/FM, can play from an SD card and is, of course, Bluetooth as well. The radio requires no soldering–instead, it appears to be a modular snap-together kit. Here’s the manufacturer’s description:

Noyce Joyce introduces a new generation of electronic kits.
The whole kit is made of printed circuit boards (PCBs).
With a simple snap-fit connection, you get a fully functional product. In this case a battery-powered radio/Bluetooth speaker.
Our radio is [truly] unique thanks to the used miniature IN-17 nixie tubes.
These nixies stopped production 50 years ago.
For this reason, this product will be available only be in limited quantities of maximum few hundred pieces.
Right now you can buy the first 100 pieces in advance for half price.
These pieces will be delivered at the end of July.
