Radio Hams Unite Woman with Family

A group of amateur radio enthusiasts united a Lucknow woman who had got estranged from her family in India.

Sikha Sharma was spotted at Shyamnagar radio station in a drowsy condition and was initially unable to tell anything about her whereabouts. HAM radio operator Somnath Adhikary VU3ZSA representing West Bengal Radio Club (Amateur Club) based in Sodepur, first spotted her at the railway station wandering aimlessly.

He immediately contacted the secretary of the Club Ambarish Nag Biswas VU2JFA who instructed him that they should render assistance to the woman who was in some sort of trouble. Soon, two other HAM operators staying near Shyamnagar joined Adhikary and they took the woman to the Government Railway Police (GRP).

Are Electric Cars Greater Ham Radio Threat than PLT?

The South African Radio League are suggesting that electric car charging stations could pose a greater threat to amateur radio than Power Line Telecommunication (PLT).

The looming problem was extensively discussed during an IARU EMC committee meeting.  There is currently no consensus amongst various technical bodies such as ETSI, CEPT, CIPR and ITU about the inference limits.

One of the problems the committee identified is that the delegations who attend these meetings are not necessarily people experienced in radio and telecommunications and are more concerned about how fast these electric car batteries can be charged.  This is one of the aspects that will be discussed at the IARU Region 1 meeting with a call to mobilise national societies to start talking with their standard bodies.

The SARL is represented on the TC73 committee of the SABS where EMC and EMI matters are dealt with. The SARL representative, Hans van de Groenendaal, will also raise the issue at Working Group 5 of TC73 due to meet in the next two months.

Report VDSL interference NOW

For three years the RSGB EMC Committee has been investigating the problems of interference from VDSL broadband on the HF amateur bands and lobbying for action to reduce the problem.

It has a lot of historical data, but both Ofcom and Openreach contend that 150 reports from 50,000 amateurs are not indicative of a major problem when there are 9.5 million VDSL installations deployed.

RSGB EMC Committee has set up a survey to collect current signal levels at the frequencies of VDSL band transitions, which indicate the presence and strength of interference. It is very simple to do you just tune your receiver (set to AM or SSB 3kHz bandwidth) to each frequency requested note the S meter reading on the survey form. Full instructions are included in the survey.

The EMC Committee plans to present its findings at the RSGB Convention in October and then use them to persuade Openreach to take further action.
