The "High-Frequency Parties" return!

You might remember our previous input on SWBC matters several years back. Now, with this pending application containing potentially "spurious emissions", we have decided to say our piece. We are known as the High-Frequency Parties, consisting of Benn Kobb, Dr. Kim Andrew Elliott and myself, Christopher Rumbaugh.

We're filing an objection with the FCC to an application for International Broadcast Station being proposed in Illinois. Do we want and support DRM? Of Course we do! Do we believe that latency arbitrage in International Shortwave Broadcast Bands is a deleterious intruder? You bet your sweet bippy we do! Read our take here.

Once again, antiquated rules are hindering radio technologies. In this case, latency arbitrage is certainly a reasonable use of radio waves - but it does not belong in-band with International Broadcast stations. International Broadcast bands are global-village shared public resources for the promotion of culture, ideas and mutual understanding - not encrypted financial trading data.

UPDATE 20200708 1830 UTC : Here is an article in Radioworld on the "High-Frequency Parties" objection filing.

Again with the DRM and a "bonus" arbitrage payload

Yet again, another arbitrage shortwave plan, this one from Batavia Illinois.

Brother Zyg says this smells like what we have already seen with WINB and the never-developed Turms Tech project. Brother Benn says "Arbitrage shortwave transmission is not broadcasting as defined in Part 73F for International Broadcast Stations."

Religious investment? I like the TCI wire Log. They can divert that to my acreage!

New crop of DRM receivers from Gospell

I got this email today:

"Glad to hear that you're on the market for DRM Radio Receiver,we are a professional manufacturer in China, hoping to establish business relationship with you. In my following email, we recommend some of our hot selling products for your reference."

Accompanied by this link

HaoChun Liu @HCLiu11 (who should be familiar to many DRM enthusiasts from his work at Newstar and Gospell) showed off a few of these sets in Twitter teasers earlier in the year.

We reviewed the GR-216 several years back. I have no further information on these new sets, other than what I have seen on Twitter. I'm always glad to see new receivers on the market. Several of these are even battery powered, which is great news.

xHE-AAC decoder for DReaM


We have heard lots about how great xHE-AAC is, yet there have been significant hurdles to getting a version of DReaM to decode it. @zefie has solved many of those problem here. Be sure to read his caveats, but great work!
