iHeartMedia San Diego said it has completed the acquisition of KFMB(AM) from Local Media San Diego; and as of today the station, heard on 760 kHz, has changed its call letters to KGB(AM).
“As part of terms of sale, TEGNA Inc. retained ownership of the KFMB(AM) call letters, which required iHeartMedia to make the change,” iHeart stated in an announcement.
“The Federal Communications Commission has approved the use of new call letters KGB for AM 760.”
[Related: “San Diego Stations Hit by Wave of Firings and Potential Job Cuts,” Jan. 2020]
It quoted Market President Melissa Forrest noting that the KGB call letters are legendary in San Diego. The company already uses them on an FM signal in the market. The AM format is talk; iHeartMedia began operating KFMB under a local marketing agreement in March.
iHeartMedia San Diego’s holdings now are KGB(AM), KGB(FM), KHTS(FM), KIOZ(FM), KLSD(AM), KMYI(FM), KOGO(AM) and KSSX(FM).

Two articles from The Guardian telling the sad story about the fast decline of MW radio stations in the UK.

WTZA AM 1010 kHz Atlanta, GA USA on at high power at night.
Recently WTZA AM 1010 kHz in Atlanta, Georgia USA signed on simulcasting the Radio Punjab network. It is normally a 50 kW AM station during the day. However, the station is failing to drop down to its 78 watts at night. It is staying at its 50 kW daytime power (or maybe the critical hours power of 45 kW) throughout the night.
The station should be easy to receive at least in the southeast U.S. I was able to verify this on KiwiSDRs located in NC and Key West, FL.
Confusingly, the station broadcasts a station ID at the top of the hour as KTXV AM 890 in Dallas, TX. The ID is in English. Apparently, relaying an online feed from this Rado Punjab affiliate. No local station ID has been heard since it signed on with this format in late May. Radio Punjab broadcasts in the Punjabi and other south Asian languages with some commercials in English.

Greece

A rare guest in the medium-wave band is active again: “Radio Nove Thessaloniki” from Greece on 1.206 kHz can be heard around 20 UT.
Yes, Radio 9’s announcement is in Italian. The station was last heard December 2019; since Israel switched off its transmitter in Akko, the frequency has been relatively free.
Translated from German:
“Ein seltener Gast im Mittelwellenband ist wieder aktiv: “Radio Nove Thessaloniki” aus Griechenland auf 1.206 kHz ist gegen 20 Uhr UT zu hören. Ja, die Ansage von Radio 9 ist in Italienisch. Zuletzt gehört wurde die Station letzten Dezember, seit Israel seinen Sender in Akko abgeschaltet hat ist die Frequenz relativ frei.”
