This  is a repeat of what you did the day before the eclipse.

8:30 am to 13:00

Record the time of each measurement (they don't have to be evenly spaced). Once every 20 minutes is fine, if you want to make samples more often then that is better. But the intention is not to stop you  enjoying the eclipse.

When will the eclipse effect the radio

An important thing to note is that the maximum effect on your radio signal WILL NOT be the same as the eclipse is at its maximum overhead. Why?
So making these observations should NOT interrupt your eclipse watching (please look at the safety information about not looking at the sun).

About 40-30 minutes before of the moment of totality for the radio path, things will hopefully change much more rapidly. At this time you may want to make observations more often.

Each time you make an observation:

If you are transmitting, If you are receiving, Continue after the time eclipse will have past for  about 2 hours (so to about 13:00 BST).

If at anytime your reception was affected by interference from another station, please DO note it down when it occurred.
If you cannot give your signal strength readings in dB (dB above noise) then use whatever units are on your S-meter is fine.

What not to do

Once you have set your equipment up for the start of the experiment you must resist the temptation to change it, particularly the transmit power or the automatic gain or bandwidth on the receive station
