SEPTEMBER 2022 REPORTS
Reception continued into September and in Épinal, France, Niels van der Linden reports further TV successes in Band I where signals on channels R1 (49.75MHz) and R2 (59.25MHz) were observed on at least 36 days throughout the summer months. Images on channels E3 (55.25MHz), E4 (61.25MHz) and A2 (55.25MHz, 525-line 60Hz) have also been observed, but so far remain unidentified.
On the 3rd, Niels’ son noticed colour images on channel R2 at levels somewhat stronger than usual but there was no visible logo, only a sign-language interpreter in the lower right of the screen. It is thought that this was the local news programme of ‘Lugansk 24’ (Telekanal 24) via the Lugansk transmitter (50kW ERP) in Ukraine. The reception lasted from 1015 until 1035UTC. Niels first received this network in July 2016 after it had replaced ‘Inter’.
Niels adds that maybe this is the final farewell for the reception of analogue TV transmitters in VHF Bands I and II via Sporadic-E. Hopefully not!
We hope to be able to continue reporting further analogue sightings via Sporadic-E next season, but the greater skip distances involved may mean reception could be more challenging for UK DX-ers.

Dave Bunyan (Sittingbourne) reflects on this season’s rich pickings. Towards the end of the season, on August 21st, signals from Cyprus (3,100 km), Israel (3,550km), Lebanon (3,550km) and Saudi Arabia (4,265km) were identified. The

Roger also asks whether there are any European transmitters operating above UHF channel D49. Maybe our European counterparts can fill us in with any other transmitters still operating as the UHF band gives way to mobile ‘phones.
In the golden era of analogue DX-ing, Band III signals from Éire, Belgium and France could be received almost daily in central parts of the UK, albeit at a low level. In Derby, French 819-line signals in Band III from Lille (channel F8A: 185.25MHz vision) could be received regularly in the Midlands using an unmodified dual-standard receiver (Thorn 1400 series) set to 405-lines, resulting in two pictures side-by-side.
For general DX-ing in those days, many DX-ers used receivers with a reduced vision IF bandwidth which provided enhancement of weaker signals and also greater selectivity to cope with differences in channel allocations throughout Bands I and III. Modifying an old dual-standard receiver, to take advantage of the 405-line’s narrower IF bandwidth worked wonders with weak-signal reception, but modifications were not for the faint-hearted, By the late 70s, such receivers were increasingly difficult to come by and were probably well past their sell-by date!
Some enthusiasts began experimenting with external varicap tuning systems which fed a selective, and narrowed, bandwidth IF stage before up-conversion to a UHF channel using a VHF to UHF up-converter. Such devices were commonly used in older VHF TV communal aerial systems to convert signals to UHF frequencies.
The concept of an external DX tuning system feeding a normal UHF TV meant that no receiver modifications were necessary and the DX-TV reception hobby was available to anyone.
In 1983, a stand-alone device called a D100 was produced by yours truly and once the results were seen and word got around, demand took off. The D100, marketed by HS Publications of Derby, evolved over the years. The first ones were vision-only with results similar to a modified TV set, but later the luxury of multi-system sound was added when hooked up to an FM radio.
All models featured variable IF bandwidth to provide an optimum display. Later options included scanning and even a DX signal alarm facility to warn of activity during lulls. The D100 was despatched to all corners of the globe until spares finally dried up in 2019. By that time, analogue was well into its final days.
In the Philippines, All TV Channel 2, a free-to-air TV network based in Mandaluyong, has commenced broadcasting in analogue on channel A2 (55.25MHz) in Manila with 30kW ERP.
These channels were previously used by ABS-CBN using the call-sign DWWX-TV. The ABS-CBN network was closed down on
In June 2022, AMBS Manila began its test broadcasts and the station made its ‘soft launch’ on
