This was a week or so back, so I am reporting somewhat belatedly.
Starting on 24th October There was some enhanced propagation. In the afternoon on 2 metres I worked EI9KP in IO54, in Sligo, for a rare square. In the evening I worked:
And on 25th:
And I heard EA2TZ who did not stay on frequency to work calling G stations.
I also worked on 24th with one watt on 70 centimetres F6FGQ immediately before the contact on 2 metres.
A limited opening but a nice one.
After several decades absence I have been operational on 2 metres SSB since the end of February 2018. I have been using an old Eighties FT290R and a small amplifier running only 25 watts to a 7-element antenna.
I have not observed any spectacular tropo openings, but last week we had some propagation into Scandinavia.
On 8th October in the evening I worked
OZ6OL JO65dj 878 km
SM7DTT JO65lj 923 km
SM7NR JO76rc 1091 km
And on the morning of 9th
SM7NR JO76 again with minimal activity from UK.
On 70 cms with one watt SSB from an FT790R I worked on the morning of 9th:
OZ9FW JO65co 882 km
And in the UKAC 70 cms contest in the evening of 9th with one watt:
SK7MW JO65mj 923 km
OV2T JO46qh 774 km
The opening seemed very localised. There was not much good propagation in between, at least as far as my location in Hockley, Essex was concerned. However, good results can be had with a modest station. I am hoping to have a bit more power soon.
I had read something to do with electromagnetic interference from LED bulbs in one of the radio magazines but had not given it too much thought. I am in the process of setting up my station and will operate primarily from 144 MHz up, at least initially. My radio room is upstairs in our small house.
I do not have equipment for measuring radio noise. One generally accepts what we have and without specialist gear it is hard to know what the noise floor is on any particular rig. However, the other evening, while I was listening in my vertical collinear with my FT290R in SSB mode, my wife switched on the bathroom lights, and immediately the hiss or hash increased, which would have drowned out a weak signal had I been listening to one.
The bathroom lighting consists of two LED spotlight bulbs. Further experimentation has caused me to realise that there is also an issue with the LED bulb in the radio room.
Naturally I have looked at what alternative might be available. Currently we can still buy halogen bulbs in the UK, but according to the local shop sales person and as apparently confirmed elsewhere, from September 2018 we will not be able to obtain other types than LED.
There is no doubt there is an issue in the general consumer market with interference to DAB radios
My local issue seems mainly to affect 144 MHz with little noticeable interference at 432 MHz, and although I have not looked at every amateur band, in my case there is not any perceivable hash as low as 3.5 MHz, but of course there my noise level is typically S7 anyway.
More on this issue can be found here and it is well worth watching the video by DL9KCE who shows that even a bulb made by a well-known European manufacturer causes a problem at 144 MHz.
We need to launch a campaign although it seems we may be overwhelmed by an inexorable tide to LEDs. What will become of 2 metres weak signal work in an urban environment?
