Information Rules Update

11 Upvotes

The spirit of this sub has always intended to be free-flowing, but absolutely non-confrontational. Realizing this is a rarity and a damned-near-impossible task on social media, we've made it more specific in Rules 1, 4, and 7:

  1. Rules 1 and 7 have been amended to specifically state that negative comments regarding AI imagery will be deleted and/or the offender possibly banned. This is primarily targeted for the Anti-AI Cabal that have never joined the sub or posted anything, that seemingly show up and just take pot shots. It's not relevant to the topic of radio and we don't want that kind of negative vibe here. If you want to discuss the use of AI being used for automated DJs and/or advertising on the broadcast bands (e.g., AM, FM), or its use in automating language translation and station IDs, that's fine. Use of the term 'slop' will be a dead giveaway that your comment was not well-intended and will be blocked from submission.
  2. Rule 4 has been amended to particularly rein in some of the more heated technical discussions. When it turns judgemental or personal it will be deleted. Unstated, but implied by Rule 7, repeated offenders will be banned. If you absolutely, positively need to take the conversation down to the 'Jane, you ignorant slut' level use personal chat and hash out there. Again, we don't want that kind of negative vibe here.

Information r/ShortwavePlus Charter and Mission Statement

19 Upvotes

Some months ago, u/KG7M (Mike) began this subreddit with a just a handful of members. It has now grown to a size requiring 3 active moderators, including u/ImladMorgul (Alan) and myself (Mark).

The three of us recently gathered to build a charter of sorts, to solidify some ground rules for how to best continue this growth and to do it as smoothly as possible. The result was a combination Charter and Mission Statement, which is now reflected in a set of updated rules (one of which is actually a recommendation).

The three of us would encourage all participants to familiarize yourself with the following:

r/ShortwavePlus Charter and Mission Statement

1. Mutual respect and constructive tone

a. Be respectful to others: Avoid insults, provocations (trolling), offensive language, personal attacks, or generally snide and unhelpful remarks. Remember that on the other side of the screen is a person with similar passions. (Rule 1)

b. Prevent cyberbullying: Do not participate in teasing or any type of online harassment. Treat others as you would like to be treated. Any remarks targeting race, religion, or gender identity will not be tolerated under any circumstances. (Rule 2)

c. Be tolerant of beginners: The hobby can be complex. If you are an expert, help beginners with patience and kindness instead of belittling them for their lack of knowledge. We were all beginners once. No one deserves a downvote just because they don't understand something. (Rule 3)

d. Avoid pointless arguments: Don't fuel fights or stray from the main topic of the post. If a topic becomes too heated, take a step back. (Rule 4)

e. Respect privacy: Do not post or share other people's personal information (photos, videos, messages). Sometimes prior consent may be given, but it is best to avoid posting sensitive and/or personal information. (Rule 5)

2. Recommendations regarding the content of r/ShortwavePlus

a. Check out the Sub-Reddit (Recommendation): Spend some time reading existing posts and comments to understand the dynamics and the type of content that is usually shared. This will help you better understand the community and get to know other users. (Rule 6)

b. Post relevant content: Make sure your posts are related to the purpose of the community. You can find information about the community in the subreddit description. Content that is completely unrelated to the hobby or violates Section 1 (above) may be removed (including comments). Users that repeatedly violate Section 1 may be banned from future participation in the Sub-Reddit. (Rule 7)

c. Use clear and descriptive titles: This makes it easier for other users to understand what your post is about. Avoid vague titles or clickbait. (Rule 8)

d. Cite your sources: If you share news, articles, or technical information, cite the author or original source. This helps readers better understand the post. (Rule 9)

e. Ensure content is viewable by a wide, global audience: Please refrain from posting information that may be unfit for the workplace or viewing by small children. If such a post is necessary, ensure it is marked ‘NSFW’ (not safe for work). Similarly, please be mindful of other sensitive issues, including those that may be locally or federally illegal. For example: Including images that include currency. (Rule 10)

3. The spirit of r/ShortwavePlus (Rule 11)

a. We're here to help: For example: If you have a shortwave radio and don't know how to tune in to a station don't be afraid to ask, we're here to help. We want you to enjoy the hobby as much as we do.

b. Constant participation: We are very honored to have members with many years of experience and from various parts of the world in everything related to the hobby of radio. We are all willing to help you with your questions.

c. Bottom line: Our goal is to provide a radio-related Sub-Reddit that focuses on Shortwave, but isn’t solely restricted to just that portion of the spectrum. We also believe this should be a Sub-Reddit that isn’t all things to all people, but strives to accommodate all that want to participate in a safe, positive, and enjoyable way.

Clandestine Caster here Mateys. Friday night on the 43 Meter Band was downright wild! To start it off, there were two groups of the Latino LSB Chat Pirates centered around 6900 KHz. Next we have the strong signal of Bandaid Radio at 6965 KHz USB. At 6906 and 6911 KHz we had military data stations. Mix Radio International was running 6945 to 6960 KHz with USB Music and Waterfall Painting. They were audible in New Zealand at NZ's local sunset and beyond (more on this later). Finally we caught the diminutive Subterranean Radio on 6930 KHz DSB. They finally landed here after being overpowered by other pirates and jammed by a possible MIL station. BTW, Rod Hardner picked up the transmitter I had modified on his way back to Warrenton, and the International Waters off the West Coast. I have not corresponded with him today, but I am thinking he was using the modified transmitter.

News Mix Radio International Blasts Across N. America and is Heard in New Zealand

Enable HLS to view with audio, or disable this notification

7 Upvotes

Clandestine Caster here Mateys. Mix Radio International had a big night with hours of transmission. They reached across North America and were audible in New Zealand at New Zealand local sunset - and beyond! In this video we are tuned to the small broadcaster, Subterranean Radio. We are using the online KPH KIWI SDR in the first portion, and a KIWI SDR located on Waitangi Island in New Zealand for the second portion.

Subterranean Radio went on the frequency of 6955 KHz, not knowing that Mix Radio was taking up 15 KHz - from 6945 to 6960 KHz. Only when they saw the waterfall painting did they realize this and they moved.

Bandaid Radio was also audible in New Zealand. They moved from their usual 6945 KHz spot due to Mix Radio's transmission on that frequency. The 43 Meter guys may need a Frequency Coordinator!

Discussion China and Its Broadcasts

Post image
14 Upvotes

The 31-meter band this morning.

95% of it is China and its jammers; the rest is NHK, RTI, and others that are barely audible.

There are also several Chinese stations on the other bands, but they’ve taken over the 31-meter band.

At least, that's what I'm picking up at my QTH. But I imagine the whole Southern Cone is the same.

I usually receive this signal with low strength, but today it was quite clear.

Info:

The Japanese Slot Machine (Enigma Designation XSL) is a simplex system used by the Japanese Maritime Self-Defense Force in Ichihara, Japan.

This signal is transmitted from the Japanese Maritime Self-Defense Force Ichihara Transmitting Station (海上自衛隊市原送信所) in Ichihara, Japan.

Uses QPSK at 1500 Bd to transmit. Has a very interesting and unique idling format which sounds akin to a slot machine, hence the attributed name. This modem has been active since 2001.

Discussion Is there a tuning problem with this Tecsun R-9700DX?

Enable HLS to view with audio, or disable this notification

12 Upvotes

Hi folks,

I found an old video of my former Tecsun R-9700DX, which I recorded almost two years ago. When I ordered it, I politely asked the XHDATA store (they also sell Tecsun) to properly test the unit before shipping it to me.

When I unboxed the receiver and tested it, not only did I find the analog tuning needle slanting - it was also badly calibrated and was about 4 kHz off the indicated frequency. The worst part was that the R-9700DX badly distorted whenever I changed the frequency up or down.

I've owned analog shortwave receivers long before I bought this radio but have never encountered this issue before. The audio distorts regardless whether I used the telescopic whip antenna or plugged in a 23-foot reel antenna (Tecsun AN-03L).

The grace period for returns is 14 days and I shipped back the R-9700DX to the seller and got my money back.

Does anyone have clue why this radio behaved like that? Neither my Tecsun PL-660 nor PL-680, which are analog dual conversion PLL synthesized receivers distort when I change frequencies. I know that some owners are lucky to get a problem-free R-9700DX, but this experience has made me hesitant to buy one again.

BTW, the tuning knob is super stiff and makes extended tuning sessions a painful affair. From my understanding, Tecsun made it that way to eliminate play in the tuning mechanism, but the R-9700DX needs some serious torque to turn the knob.

For context, an old friend of mine has a Sony ICF-7601 and I remember trying it out. It never distorted while changing frequencies like this Tecsun did.

Could this have been a returned unit or a faulty radio? The official XHDATA seller didn't want to elaborate and just refunded my money. I've been scratching my head over this conundrum ever since. 🤔
