Utility / Re: What's up with WLO Marine?
« on: May 24, 2023, 2308 UTC »
WLO was gone for a long time, now it's back with test transmissions at various times on 8788 khz USB. Widely reported on the RadioRef utilities forum and also mentioned on the UDXF forum.  No known solid schedule yet, so it's catch as catch can


Utility / A special broadcast from SW Radiogram using EasyDRF
« on: May 09, 2023, 1849 UTC »
I don't know how many here know about the digital broadcasts done by WINB Red Lion and WRMI.  These broadcasts are used to test how well digital reception (including pix) can make it to other parts of the world that are normally jammed. Normally MFSK modes are used, and Olivia has been used in the past

This week the program will be sent using EasyDRF, a modified version of HamDRM from DazMan in Australia. The data from the 300th broadcast of the RadioGram will be used.

You can find the schedule, where to get EasyDRF, some tips on using it and a sample audio file from here



Equipment / Re: Can an antenna work while laying on the ground?
« on: March 26, 2023, 0123 UTC »
There are several links to the subject of loops on the ground (LOG) antennas here in the RadioReference wiki....



Copied verbatim - any errors are entirely mine

Apparently excludes North Americans. But linx to other refs abottom

Huge list in alfabetical order by name, skipping the word ``radio`` if precedes name.


Equipment / Antennas for postage stamp size lots

Tiny yards are a challenge to put up a reasonable HF antenna, but there are a few things you can do.  See https://forums.radioreference.com/threads/antennas-for-postage-stamp-sized-lots.429144/


Shortwave Broadcast / Peru's bicentennial is coming up
« on: July 18, 2021, 2329 UTC »
As mentioned in the SWLing.com blog and World of Radio (undoubtedly elsewhere too), Peru's bicentennial is July 29. This is a fairly tough country to hear, but there are a few stations that have been reported in the past weeks. Expect extended schedules and programming not just in Spanish but in other Andean languages such as Quechua. These frequencies are nominal; they can and sometimes do drift...
4775 R Tarma
4752 R Huanta 2000
5025 R Quillabamba (if Cuba isn't there)
6174 R Tawantinsuyo


Just caught them saying this is Enigma 7 calling twice into SSTV 0033 UT

Latin American Pirate / Re: ROCV 6906 off the air
« on: January 08, 2021, 2134 UTC »
From Manuel Mendez on the WoR reflector...

VENEZUELA, Radio Onda Corta Venezuela, El Tigre, 6200 and 7375. According with information in the Wathsapp Group " Banda Corta Venezuela" from the owner and t echnical director of R. O. C. V. , Gregorio Kina, this station will be back to the air very soon, probably next Sunday, alternating 6200 and 7375 kHz. Gregorio is currently adjusting the antennas of the station.


Latin American Pirate / ROCV 6906 off the air
« on: November 21, 2020, 2138 UTC »
According to World of Radio, ROCV has suffered some sort of electrical problem. How long this is going to take to fix is anyone's guess.  I'd periodically check this frequency, and keep an eye on the World of Radio reflector on groups.io for more....Mike

HF Mystery Signals / Re: New digi mode on 4207cf ?
« on: November 07, 2020, 2213 UTC »
The best place to post questions like these is the Utility DXers Forum reflector on groups.io.  They have a lot of folks that can help with digis like these



Join up with the Utility DXers Forum (UDXF) at groups.io - this reflector is probably the best place to get answers to questions like these



Note that it's been reported that ROCV (the station name) means Radio Onda Corta Venezuela (per World of Radio logs).  As I understand it, they have applied for a license but given Maduro's oppressive regime, it's anyone's guess as to whether it will be granted.


This is likely to be the widely reported Venezuelan relay of LV Del Tigre - the actual frequency varies from 6906.15 to 6906.5 from day to day.

Good to have this country back on the air.  Right now they are a 'pirate' because they don't have a license from the Maduro government yet.  Whether they get one or not remains to be seen...Mike

Still going at 0145 using the N4TVC Kiwi. Another interesting choice of frequency...Mike

Still going on, a bit weak but in the clear on both frequencies at 0134. Interesting choice of frequency on 3480.  Heard on the Alexandria VA Kiwi
