Radio Panj 1521. This station seems to have technical problems today. At 0945 utc a very low level distorted audio stream can be heard on a seemingly normal carrier. But during news at 1000utc the audio level improved but audio is rough sounding and sibilant.
Not actually mixed, but symmetric transmitter spurs from 1548 kHz, the upper one is on 1556.5v kHz. They wander a bit and vary in strength, sometimes almost inaudible. Also 1413 kHz often has them around 1395 & 1431 kHz, but I did not find them last night.
The new Romanian KiwiSDR provides false receptions, because the local station on 1314 kHz is overloading the receiver. The owner must build a Notch filter for 1314 kHz to avoid it. Ha had the same situation with Kossuth Rádió on 540 kHz. Since its signal is reduced via the notch, my Kiwi works great! A useful calculator can be found here: http://www.learningaboutelectronics.com/Articles/Notch-filter-calculator.php Note, for the best results the filter must be “puzzled out” with various capacitors around the calculated value.
QUINCY (WGEM) – WGEM-AM continues to deal with a technical emergency that began in late June, according to WGEM General Manager Ben Van Ness.
WGEM Chief Engineer Brent Clingingsmith said WGEM 1440 AM suffered the loss of its main and backup transmitters in a relatively short amount of time.
“Due to a variety of challenges that come along with this, it will take quite some time before we know what our next steps might be or can be,” Van Ness said.
Van Ness pointed out that all of the WGEM Sports Radio programming remains available on 98.9 FM.
Clingingsmith said the 98.9 FM signal is of better quality and covers a larger radius 24 hours a day than the 1440 AM signal, which had to go to low power after sunset.
Van Ness added the FM signal is also more reliable than the AM signal and encourages all listeners to tune into 98.9 FM.
“This situation has been reported to the FCC and WGEM remains compliant with all rules and regulations that are set forth by the FCC when operating a translator (98.9 FM) on our AM station (1440),” Van Ness said.
From my Kauai DXpedition partner Chris Rogers comes news of an improved MW antenna for the 10 kW Tongan station A3Z in Nuku’alofa, as detailed in the station’s Facebook page at https://www.facebook.com/TBCA3Z Although Chris doesn’t yet know if the new antenna is operational, the station was already the strongest DU blaster overall at the Rockwork cliff, and its signal it will be thoroughly evaluated there starting Monday morning.

Lots of photos on their FB including eventually on July 29, antennas. Mostly in Tongalese.
