There have been some remarkable contacts made on 144 MHz recently via Trans-Equatorial Propagation (TEP) from the Caribbean to South America with many in the region of 4000 to 5000 kms. One of the most impressive was a contact between P41E on the island of Aruba and LU2EPO near Buenos Aires in Argentina, a distance of just over 5400 kms……………….CLICK for more.
Charles Clifford “Cliff” Kayhart, W4KKP, of White Rock, South Carolina, died on October 26, a few days past his 109th birthday. An ARRL member, he was the oldest known US radio amateur and possibly the oldest ham in the world.

Eleven schools across the US launched helium-filled balloons carrying amateur radio payloads on October 9. The Smithsonian Air and Space Museum live-streamed the multiple launches. The balloons are trackable via ham radio on APRS (either 144.39 MHz FM or 144.34 MHz FM)…………..
Ofcom is introducing new licence conditions for spectrum users, to ensure their equipment continues to operate within international electromagnetic field (EMF) guidelines.
All use of spectrum generates electromagnetic fields.
There are international safety guidelines – developed by the International Commission for Non-Ionizing Radiation Protection (ICNIRP) – that set the maximum levels of EMF exposure for protection of the general public. These levels are endorsed by Public Health England.
Manufacturers, installers and operators of wireless equipment should already be aware of the ICNIRP guidelines and factor them into how they plan their services.
To ensure this always remains the case, we proposed new conditions for spectrum licensees earlier this year. Following consultation, we have now decided to introduce the new licence conditions.
This means licensees using equipment that is authorised to transmit at power levels higher than 10 Watts must operate within the ICNIRP guidelines as a condition of their Ofcom licence – including keeping data and records of any testing to demonstrate their compliance.
NEW ONLINE TOOL
While most spectrum licensees should already be factoring the ICNIRP guidelines into their services, we will be launching an online tool (our EMF calculator) to help make it as simple as possible for people to check whether the use of their radio equipment is likely to comply with the guidelines. This will be available on a trial basis initially and we will take account of the feedback we receive before launching the full version.
Alongside our decision to introduce the new licence condition, we have published a consultation covering the updated wording of the condition; our updated Guidance on EMF Compliance and Enforcement; and a trial version of our new online EMF Calculator. We welcome feedback to this by 16 November, after which we will then begin varying the relevant licences to include the new condition. We will also launch our finalised online EMF calculator
