B25 TRANSMISSION CHANGES

Some New Frequencies

In the coming week, I have some essential non-radio-related radio projects that require my attention. I won't have much time to spend at the radios. So, for the first time in some years, I won't be developing a massive list of new frequency observations for publication here on the MEDXR blog.

However, below is a list of 60 schedule changes made by some broadcasters that I have monitored in the past few days since the start of the new B25 transmission season last Sunday.

For each item, I have tried to identify the former frequency used in the A25 season. But this can be hard because schedules can be complex or drastically changed by the broadcaster, making direct comparisons difficult.

The list is in frequency order. The countries listed are where the transmitter sites are located. Many broadcasters use transmitters in other countries to improve reception in their target zones. For example, the world-famous BBC is currently using this long list of relays for the B25 transmission season: Oman, Ascension Island, Tajikistan, Uzbekistan, United Arab Emirates, Vatican City, and Madagascar, as well as its own transmitters in Woofferton, England!

In most cases, I have listed the sign-on and sign-off times for each broadcast. These are represented by asterisks * before the sign-on time and after the sign-off time. I hope readers will find this information more useful. Comments on signal strength, as noted here at Mount Evelyn, are largely irrelevant and have not been included, except for a few remarks on interference (QRM) from other stations.

Equipment: SDRPlay RSPduo, Yaesu FTDX3000 transceiver, Kenwood R5000 receiver, Yaesu FRG 100 receiver, Kenwood TS2000 transceiver.

Antennas: 80m long horizontal sky loop antenna, a delta loop antenna for 10 MHz, a double bazooka antenna for 14 MHz and a 5/8λ centre-fed vertical for 21 MHz and above.

Abbreviations:
NF = New Frequency for the A24 transmission season

NS = New Site (i.e. a change in relay station for a specific broadcast)
QRM = Interference from another station
// = The same broadcast simultaneously on another frequency, i.e. in parallel.

WS = BBC World Service

AF = Africa. Eu = Europe, As = Asia, ME = Middle East, NAm = North America, CAm = Central America, SAm = South America, Oc = Oceania, AFG = Afghanistan,

N = North, S = South, E = East, W = West

ENAm = Eastern North America, NEAs = North East Asia, etc.
