Helliniki Radiophonia on 9,420 kHz or 9,415 kHz?

GreeceSWLing Post reader, Mark Clark writes:

“Tuned [to Helliniki Radiophonia] during band scan at 0110 UT. It was playing 1970s rock music like Love is Like Oxygen by Sweet and Evil Woman by ELO. Male announcer speaking in Greek between each song. Initial signal strength was weak SIO 233 on PL-880 and PL-380. Also weak and noisy on University of Twente Websdr. Switched to local Perseus with Wellbrook antenna. Reception improved from SIO 443 to SIO 555 during recording of 100 kHz wide RF from 0126 to 0140.

Observation showed carrier on 9415 with nothing on assigned 9420 kHz as per Aoki and EiBi. Switched back to PL-880 as signal had improved to SIO 555. PL-880 with internal whip provided easy copy from 0140 to 0145 when signal suddenly dropped out. Signal returned several seconds later but decidedly not on 9415. Tuning to 9420 restored clear strong signal. Verified via local Perseus receiver that carrier was now on 9420 with no carrier at 9415. Same male announcer was noted between songs at 0153. University of Twente Websdr also showed same shift. Ended reception at 0154 UT.”

Many thanks for this detailed listener report, Mark.  Indeed, several of us have noted Helliniki Radiophonia on 9,415 occasionally. Last year, I made all-night recordings where RH remained on 9,415 the entire time.

I have no idea why RH is hopping between 9,415 and 9,420 kHz. Initially, I thought this may be due to the fact that they were silent on 9,420 for an extended perios of time last year and Voice Of Islamic Republic of Iran, who shares the same frequency, seemed to take its place. I even had a few readers note that when Helliniki Radiophonia returned to 9,420 kHz, interference from Iran was substantial and the occasional move to 9,415 kHz was, perhaps, to obtain a clear frequency.

In truth, though, this is speculation; is this frequency shift deliberate or accidental? Do any SWLing Post readers have a definitive answer?

Shortwave Radio Recordings: Voice Of Islamic Republic of Iran

Tehran, Iran

Tehran, Iran

On Thursday, March 14th, I tuned to the Voice of the Islamic Republic of Iran on 9.895 MHz at 02:30 UTC.

The signal was strong, but audio somewhat typically over-modulated. However, I was able to record the full broadcast.
