AI and data centres

There is no doubt that AI consumes hugs amounts of power. We have some way to go to match the memory and processing power of the human brain. I am sure this will get better with time although we are a long way away at present. 

So far I have been very impressed with Gemini AI that renders old black and white photos in colour in just seconds.

This creates a moral dilemma: we all want the benefits of AI without its power-hungry nature.

10m 2W FT8 (Tuesday)

My gear was turned on at about 1020z.

UPDATE 1832z:  So far, spotted by 354 stations. See map.

FT710 and IC7300mk2

ICOM has announced the mark 2 version of the IC7300, which has sold well across the world. 100,000 units have been sold. 

The FT-710 scores very highly on the Sherwood tests. I do not think the latest ICOM rig has been tested, although the mark 1 was somewhat lower down. For most people most of the time these numbers are academic.

Both rigs cover up to 70MHz. I know the FT710 can be widebanded without uncasing. I am not sure about the IC7300mk2.

The Yaesu radio is considerably less expensive in the UK and comes with a Yaesu cashback. I think Yaesu offers a 3 year warranty.

I am sure both are good radios.

VHF magnetic loop antenna

VK3YE is a real experimenter. This is a recent video describing the use of a tin can as a VHF loop antenna.

Times Radio on YouTube

Most days I try to watch TimesRadio on YouTube.  I find watching these most informative. They tend to interview lots of different people who have views on the international affairs.

Day off radio

 This morning we went shopping and our son and grandson came for lunch, so I am having a day off the radio.

6m 5W FT8 yesterday

In all, 20 stations spotted me on 6m QRP FT8 yesterday.  See map.  This included several continental Europeans although I am not sure of the propagation mechanism.
