Shortwave Pirate Radio In North America And Around The World, And Other Signals That Go Bump In The Night
We seek to understand and document all radio transmissions, legal and otherwise, as part of the radio listening hobby. We do not encourage any radio operations contrary to regulations.
Always consult with the appropriate authorities if you have questions concerning what is permissible in your locale.
The more or less static callsigns can be found here;
http://www.udxf.nl/MCL.pdf
The call DRY SANDS is likely of limited duration, but they can be reused a few months/weeks down the road, seen it before. These calls will typically be used by stations of the TACAMO and NIGHTWATCH programs, ie NCA assets.
There have been notedly less skykings of late and that is actually a good thing.
I expect these flights to be done more with unmanned assets than ever before, and those that are manned will likely be kept far enough away from their elint targets to not trigger a reaction from said target. Reason being, the cia guy what planned eliminating that Iranian general in Iraq was allegedly shot down in a elint flight some months ago, I fully expected war over that one but so far little mention, relatively speaking, has been made in the news. If you were monitoring HFGCS when this took place, you might have caught the response to a skyking.

For Sale / Wanted / Barter / Re: Kenwood VC-20 and YK-88A-1
« on: July 09, 2020, 1343 UTC »
If your r5k doesn't have a yk88a, this filter will surely help in situations where a 6kc filter will come in handy. The existing filter is a monolithic type with inherently very poor characteristics for a xtal filter, a yk will be better in every respect save for cost. If I had a r5k and a loose yk88a, they would soon be working together.

Not much can beat a vertical antenna for dx. Verticals offer an improved low angle of reception over a horizontal antenna.

« on: June 26, 2020, 1730 UTC »For the newbs;Josh, do you have a source one can use for identifying the various call signs? For example, Drysands is heard this morning at 17:00 UTC. Thanks! 73, Walt in Victoria, BC
BANK LOAN would be an E6 TACAMO (USN) or E4 NIGHTWATCH (USAF) checking into the NCA (National Command Authority) net on HF, they will also have a parallel network running on MILSTAR (EHF/laser satellite, use of this sat will be the obvious when the ac is offshore any real distance as some flights venture out off the coasts) and/or ground/air UHF MUX.
TWIN BED would be the current callsign of the corresponding ground comms unit supporting NCA flights via sat, UHF MUX and HF.
Some of these birds can take control of entire missile wings to launch ICBMs if needed, these flights will have to be within UHF range of the wings in question to exert control. Otherwise the flights orbit a loop (to keep that miles long trailing wire VLF antenna as vertical as possible) near a string of GEPs (Ground Entry Points) that have UHF MUX duplex capabilities including a T1 or better innernet line. The flights that venture out over the oceans will be using HF, MILSTAR, and as always VLF to the SSBNs patrolling the world.

« on: June 26, 2020, 1726 UTC »Any idea why the Skyking messages have ceased on HF?
There have been around 3 known Skyking messages for all of this year.
There have been notedly less skykings of late and that is actually a good thing.

U.S. federal, state and local government aircraft performing sensitive operations are now permitted to fly with their installed automatic dependent surveillance broadcast (ADS-B) position reporting electronics turned off, according to a new rule published by the Federal Aviation Administration (FAA) Thursday.

Think the fedz and mil are going to the adsb that does not display what type of ac or agency is operating said ac to unauthorised monitors.
