Kombucha - NOT amateur radio
Until this morning, I had never heard of this. Today, I have come across it twice within about 6 hours! Firstly I saw that a radio amateur had made some and then it appeared in the BBC Good Food magazine.
As far as I can see, it is a form of fermented tea. In Japan it refers to tea made from kelp seaweed. I think you can get kombucha in various flavours.
Funny how you can go a whole lifetime without coming across it, then it appears twice! 😄
EMF and public safety
OFCOM is consulting about the dangers of exposure to RF by the general public.
It is intending to add something in the licence to make clear that radio amateurs have to ensure the public is safe.
OFCOM and the RSGB are working on calculators so that amateurs can work out if the RF produced is likely to be a danger.
Being able to show how any potential danger was worked out could be important if a station was to be inspected, for example in the event of interference to a neighbour's TV.

OFCOM limited power FM trials
OFCOM is to trial 10 limited power FM broadcaster stations for a year and is asking for volunteers to take part. It is wondering if such licences would be suitable for hospitals and army barracks for example. Rnage could be approximately 1km.

Antenna tuner for the IC-705
ICOM has released the auto ATU for the IC-705 (the AH-705) reports Southgate News. It is quite expensive and there are lower cost auto tuners that will work as well or better e.g. the Elecraft T1. This is also smaller and probably has a wider range. It is also, lower cost.
The AH-705 is £309.60, which is expensive. The answer is use resonant antennas or lower cost tuners!
