How to find the Tecsun PL-330’s firmware version

Many thanks to SWLing Post contributor, Jaap de Goede, who shares the following note:

Thanks for posting the hidden feature table to the Tecscun PL-330.

I see more and more videos of the PL-330 popping up on YouTube. I’m wondering what firmware they run. It’s easy to identify the firmware version.

Press and hold the VM/VF button when the radio is off. Release the button when all icons are displayed. Next, the display will briefly show the firmware version in the upper right corner. As you can see in the picture (above), mine has version 3302.

Thanks so much for the tip, Jaap! I am curious, too, if Tecsun is updating the firmware version with each release/update of the PL-330. With the PL-880, there were a number of iterations all carrying the same version number (8820, if memory serves).

It would be great for comparison purposes to check the firmware number.

Elecraft KX1: Back with my portable radio companion

The Elecraft KX1

Note: This article was first published on QRPer.com.

A few weeks ago, I published a post about radios I’ve regretted selling or giving away.

Number one on that list was the Elecraft KX1.

Within a couple hours of posting that article, I had already purchased a KX1 I found on the QTH.com classifieds. It was, by any definition, an impulse purchase.

The seller, who lives about 2 hours from my QTH, described his KX1 as the full package: a complete 3 band (40/30/20M) KX1 with all of the items needed to get on the air (save batteries) in a Pelican 1060 Micro Case.

The KX1 I owned in the past was a four bander (80/40/30/20M) and I already double checked to make sure Elecraft still had a few of their 80/30 module kits available (they do!).  I do operate 80M in the field on occasion, but I really wanted the 80/30 module to get full use of the expanded HF receiver range which allows me to zero-beat broadcast stations and do a little SWLing while in the field.

The seller shipped the radio that same afternoon and I purchased it for $300 (plus shipping) based purely on his good word.

The KX1 package

I’ll admit, I was a bit nervous: I hadn’t asked all of the typical questions about dents/dings, if it smelled of cigarette smoke, and hadn’t even asked for photos. I just had a feeling it would all be good (but please, never follow my example here–I was drunk with excitement).

Here’s the photo I took after removing the Pelican case from the shipping box and opening it for the first time:

My jaw dropped.

The seller was right: everything I needed (and more!) was in the Pelican case with the KX1. Not only that, everything was labeled. An indication that the previous owner took pride in this little radio.

I don’t think the seller actually put this kit together. He bought it this way two years ago and I don’t think he ever even put it on the air based on his note to me. He sold the KX1 because he wasn’t using it.

I don’t know who the original owner was, but they did a fabulous job not only putting this field kit together, but also soldering/building the KX1. I hope the original owner reads this article sometime and steps forward.

You might note in the photo that there’s even a quick reference sheet, Morse Code reference sheet and QRP calling frequencies list attached to the Pelican’s lid inside. How clever!

I plan to replace the Morse Code sheet with a list of POTA and SOTA park/summit references and re-print the QRP calling frequencies sheet. But other than that, I’m leaving it all as-is. This might be the only time I’ve ever purchased a “package” transceiver and not modified it in some significant way.

Speaking of modifying: that 80/30 meter module? Glad I didn’t purchase one.

After putting the KX1 on a dummy load, I checked each band for output power. Band changes are made on the KX1 by pressing the “Band” button which cycles through the bands one-way. It started on 40 meters, then on to 30 meters, and 20 meters. All tested fine. Then I pressed the band button to return to 40 meters and the KX1 dived down to the 80 meter band!

Turns out, this is a four band KX1! Woo hoo! That saved me from having to purchase the $90 30/80M kit (although admittedly, I was looking forward to building it).

Photos

The only issue with the KX1 was that its paddles would only send “dit dah” from either side. I was able to fix this, though, by disassembling the paddles and fixing a short.

Although I’m currently in the process of testing the Icom IC-705, I’ve taken the KX1 along on a number of my park adventures and switched it out during band changes.

Indeed, my first two contacts were made using some nearly-depleted AA rechargeables on 30 meters: I worked a station in Iowa and one in Kansas with perhaps 1.5 watts of output power–not bad from North Carolina!

I’m super pleased to have the KX1 back in my field radio arsenal.

I name radios I plan to keep for the long-haul, so I dubbed this little KX1 “Ruby” after one of my favorite actresses, Barbara Stanwyck.

Look for Ruby and me on the air at a park or summit near you!

New Tecsun PL-368 prototype on display at 2020 Shanghai International High-End Hi-Fi Expo

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following photos and short videos of a prototype Tecsun PL-368 at the 2020 Shanghai International High-End Hi-Fi Expo.

The PL-368 appears to be the updated and upgraded model of the Tecsun PL-360/PL-365 series.

Something I note immediately is the most welcome addition of a numeric keypad for direct frequency entry:

In addition, there’s a “Sync” button indicating the PL-368 will sport synchronous detection, hopefully, with USB/LSB selectable sideband.

Photos

Note, all of the following photos and video were shared by Benny in the Tecsun PL-880 group:

Dan also shared the following short videos (click links to view):

Many thanks to Benny for sharing these photos and videos from the Expo and thanks to Dan Robinson for sending them to us.

When we learn more about the PL-368, we’ll post details on the SWLing Post. Just follow the tag: PL-368

Help using crystal calibration on the Toshiba RP-2000F

Many thanks to SWLing Post contributor, Darren Davies, who writes:

Hello Thomas,

I was gifted the Toshiba BCL receiver by an old work colleague. It’s an absolute beauty, in excellent condition and is unusual in that in comes with UK FM band and not the more popular Japanese one. It wipes the floor with newer radios on MW.

I writing to ask if any of your readers have any idea how to use the crystal calibration system. There’s very little information about the radio online and I’d like to get it into tip top condition.

Absolutely love your site and look forward to your daily emails. Keep up the good work.

Cheers Darren

First of all–wow! I love the design of this Toshiba. It’s brilliant that it even has built-in rails to protect the front panel. Obviously a radio that beckons to be taken to the field! Thanks for sharing your photos, Darren.

Post readers: If you know how to calibrate this Toshiba RP-2000F, please comment!

New DX Program

People have asked us to air a DX program for many years. KTWR had
done this a few decades ago, but we had no one to produce a new
program. Now, one of our listeners, Arun Kumar Narasimham has begun
production of the “Dxers Diary”. The first airing will be on 25
October 2020 in our 1026-1057UTC English DRM broadcast to India on
13800kHz. We are glad that Arun has stepped in to fill this
longstanding gap in our programming. We hope you enjoy it and
continue to enjoy the DX hobby.

Thank you for the tip, Ed, and we’ll look forward to any updates you might have.

Pete rediscovers the 1984 Channel 4 Film “C.Q.”

Many thanks to SWLing Post contributor,  Pete Madtone, who writes:

I was coming home from my tai chi class in the local park yesterday and remembered this play that I watched a long time ago. Please tell me you don’t know it!

[In] the credits at the end it has another radio connection: the UK reggae DJ (BBC) David Rodigan. Great eh?

“Life changes dramatically for radio amateur Norman when he gets in touch with a round-the-world yachtsman who introduces him to a different life – and a taste of fame.”

Thanks, Pete! I was not at all familiar with this TV Movie, but I absolutely love the nostalgia factor!

Post readers: Anyone familiar with “C.Q.”–? Do you remember watching it when it was first broadcast in 1984? Please comment!
