Newcastle markets - NOT amateur radio

Last week we spent a few days in Newcastle and Durham. 

We were very impressed with the fine indoor markets in Newcastle and the food prices there.

Overall, Newcastle was a pleasant surprise.

Ferrite rod antennas on TX

It is many years since I tested my own ferrite rods as transmit antennas. Quite by accident I came across this photo from 2012.

In my view these will work as TX antennas as long as the ferrite does not saturate. With modes like WSPR and FT8 on very low power I would expect to be spotted, even though the antenna might be well down on a "proper" antenna.  

As an E-field antenna made of ferrite sort of magnifies space within it it acts like a bigger antenna.

It gets worse (Google AdSense) - NOT amateur radio

Every now and again I get a message from Google AdSense. Most of these messages mean nothing to me! Take this one received today (attached). 

Basically, I just ignore these. I am awaiting a message in plain English. No doubt I shall be dead before this comes!!
