HF Propagation: K-index, SFI, …

Some Rules of Thumb

The K-index quantifies disturbances in the horizontal component of earth’s magnetic field with an integer in the range 0–9, with 1 being calm and 5 or more indicating a geomagnetic storm. Rising K-index results in a higher noise level, mainly below 10 MHz. A high noise level on 40 m does not imply a high noise level on 20 m.

The Solar Flux Index (SFI) is an indication of the degree of ionization in the higher stratospheric regions. Higher SFI values favor good propagation conditions on the amateur radio bands 20 m and above.

A special case is the 30 m band: both, SFI and K-index can have an impact on the propagation on this band. It is actually a good band in times of the solar minimum as well as the solar maximum.

Best time to operate on HF is after a solar flare eruption. As soon as the solar storm declines, the noise on the bands decreases, combined with an increase of the maximum usable frequency MUF. This often last until sunset. Propagation conditions on 40 and 80 m in the following night could be excellent. On the following day the MUF still can be raised, good for propagation on the higher HF bands.

In addition – after a solar storm – the magnetic disturbance is often very low, a good opportunity to work on 40, 80 and 160 m with low noise.

VHF Repeater Issues – Reporting

In order to improve the coverage of our SARTS VHF repeater and sort out technical problems, it is very helpful to have a list of practical issues experienced during operation. Therefore, please help and report any problem using either this Github link, or our contact form.

Please state your call sign, the power and antenna used with the description of the issue and date/time, when it appeared.

Thank You!

VHF/UHF site survey

On Sunday, 15 November SARTS will be conducting a test of a potential new VHF and UHF repeater site. We are looking for volunteers in all parts of Singapore to assist us with signal reports and two-way contacts. If you are available, please meet us on 145.550 MHz between 3:00 pm and 3:15 pm, and on 433.625 MHz from 3:15 pm – 3:30 pm local time.

After 30 June please email your logs in ADIF format to James Brooks, 9V1YC.   QSL will be by LoTW only.

Approved Rigs for Operation in SG

Dear All,

we are in the process to assemble a database with IMDA approved ham equipment for operation in Singapore.

Any operator in Singapore – whether SARTS member or not – could you please provide the following information:

  • Rig model
  • Manufacturer
  • Date of your license

Example: IC-7300, Icom, 2019

In addition, please let us know all rigs which were not approved when you applied for them.

Please send an email with this information to 9v1yc at nine-v.com or use the SARTS contact page.

SARTS History in Singapore

History

1975 – Talking to the world

The first hams in Singapore came from Britain and they arrive in the 1930s. They were assigned the callsign prefix VS1. Hams in the Federated Malaya States were assigned VS2.

1994 – Teens can now apply for ham radio license

After World War II, several Radio Societies were formed in Malaya. The state of Perak had a society, Selangor had a society and there was the Malayan Amateur Radio Transmitters Society or MARTS.

In 1949, while under the administration of the Federation of Malaya (1948 to 1957), the Singapore Amateur Radio Transmitting Society (SARTS) was formed and registered. SARTS and the other smaller societies were later absorbed into MARTS which was the largest of the radio societies in Malaya.

On 31 August 1957, the Federation of Malaya gained independence from Britain and being a new country, new entity, they were assigned the 9M prefix.

In 1963, Singapore, together with Sarawak and Sabah, became part of the Federation of Malaya, which then became Malaysia. Singapore, being part of Malaysia, was assigned the 9M4 prefix. Sarawak and Sabah were assigned 9M6.

On 9 August 1965, Singapore separated from Malaysia, and we became an independent country. Being another new country, new entity, we were assigned the 9V prefix which is in use till today.

Singapore Hams continued to be part of MARTS until it was decided that it was better for Singapore Hams and Malaysia Hams to have separate societies. The separation was an amicable one.

On 26 August 1968, the present day SARTS was formed. The first president of SARTS was Livin de Souza. The Society continues on till today.

2019 Oceania DX Contest

Coming weekend the Oceania DX Contest CW will take place. Contest period on Oct 12th, 08:00 UTC to Oct 13th, 08:00 UTC on all HF bands except WARC bands.

The object is for Oceania transmitting stations to contact as many stations as possible inside and outside the Oceania region.

Non-Oceania transmitting stations to contact as many stations as possible inside the Oceania region.

Exchange: RST report plus a progressive contact serial number starting at 001 for each band. Multiplier is the number of different valid prefixes worked (may be counted once on each band.
