Propagation News – 8 July 2018
The 2018 Baker Island DXpedition has now concluded. As we said last week, the path from the UK to the Pacific is a difficult one, but plenty of UK amateurs did manage to make a contact with KH7Z. Twenty and seventeen metres did indeed prove to be the best bands, but on the whole it […]

As predicted, the geomagnetic K-index hit five last week, although it wasn’t until early morning on the 26th. Conditions then settled as the week progressed. The US Space Weather Prediction Center has the K-index remaining low for the week commencing Sunday, 1 July, so make the most of the settled geomagnetic conditions. Due to a […]

A glancing blow from a coronal hole sent the K-index soaring to five on Tuesday, the 19th. This hadn’t been predicted by NOAA as it looked like the high-speed solar wind stream might miss us. However, by Wednesday the ionosphere had calmed down and the index returned to a more settled Kp=1. Much of the […]

It was more of the same last week with virtually zero sunspots, but some sporadic E to keep us amused on HF. We say virtually zero sunspots as a group had just appeared over the sun’s limb, pushing the sunspot number to 16 as the time of writing. This represents 10 for the single group […]

Despite poor geomagnetic conditions, HF propagation for last weekend’s National Field Day was actually better than we forecast. Norfolk Amateur Radio Club even managed to contact New Zealand via the F layer on 40 metres. NFD was no doubt helped by sporadic E, which gave good propagation to Europe on most bands. Speaking of sporadic […]
Propagation News – 3 June 2018
A large coronal hole on the Sun didn’t affect the HF bands earlier in the last week as its associated high-speed solar wind stream hadn’t had time to reach Earth. However, this was probably the quiet before the geomagnetic storm as the solar material was predicted to reach us at around 450-500km per second sometime […]
