Current propogation conditions. - UK Vintage Radio Repair and Restoration Discussion Forum

Skywave · 19th May 2010, 11:29 am

For the past few days, during daylight hours (10.00 to 15.00), propo. in the range 2.5 MHz to about 12 MHz seems exceptionally low - even allowing for the times of listening & time of year: RCI was coming through, loud and strong, of course! A quick sensitivity check on the four receivers in use indicated no problems with the receiving gear.

Can anyone here confirm these findings? Thanks.

Thanks for your reply, David.

However, even allowing for the current low sun-spot activity, things do seem exceptionally quiet, based on my listening experiences over the last 18 months. Is there a significant increase in the number of international broadcasters who are deserting the s/w bands?

you are right in as much as some countries are deserting shortwave due to cost verses internet but a quick listen around at night pulled in a lot. i tend to use a wellbrook al1350 on a rotator.. part of it may be due to sunspots part of it conditions changeing day to day

While out and about today the radio in the works vehicle suffered from breakthrough from a French station on FM which I assume was due to some "sporadic E" propogation. A quick tune around brought in some foreign stations. Conditions on the HF bands seem close to normal at my location at the moment.

Yes, Sporadic E was strong today. Radio 4 on FM on my car radio was blotted out completely by a Spanish radio station and I received Spanish TV in Band 1 (Channel E3 or E4, couldn't decide which) with an almost perfect picture.

Well, there's been no sporadic input to this Thread for quite some time now - so it seems appropriate for this Thread to be closed.
