Autumn colours - NOT amateur radio


All the seasons have a beauty all of their own with the brown leaves of autumn especially lovely as at Anglesey Abbey earlier today. 

8m ISM band for all?

At the moment, I am trying to drum up local support (near JO02DG) for some very low power WSPR tests in the 8m ISM band.  

Following a recent email from OFCOM, it is my view that anybody in the UK may use the 8m ISM band without a licence for beacons as long as they meet IR 2030. This allows 10mW ERP.   At first sight, this seems very low, but with WSPR this could well be spotted across Europe from the UK.

These local tests could indicate what might be possible.

Of course, I would much prefer a tiny, digital only, amateur allocation at 8m.

UPDATE 1228z:  Interestingly, the majority of my 10m WSPR spots today would have been possible at 10mW ERP assuming the local noise floor permitted.

UPDATE 1630z:  Several locals have offered help with my upcoming 8m WSPR tests. The tests should take place very soon, probably next week. 

UPDATE 1636z:  Of course access to the ISM bands does not have to be just 8m: here in the UK as long as long as IR 2030 is met many ISM bands could be used for beacons legally without a licence is my interpretation. ISM rules vary with countries and I am not a legal expert, so you will have to check yourself.

10m QRP WSPR TX (Wednesday)

At the moment I am on 10m WSPR TX with 500mW from my W5OLF beacon. So far, spots from the Canary Is, although I have not been on very long.

UPDATE  1543z: 10 unique stations have spotted my QRP 10m WSPR.

Oscar 100

This Qatar satellite has been in geosynchronous orbit for several years now. It has never really caught on. When I monitored last night (European evening) at 1955z there were just a few stations active on the narrowband transponder. It feels people (a very few) enjoy the challenge of getting active on the satellite, then lose interest.

DMR

Last evening, I went on DMR briefly. As I have no DMR gear, I used my Android network radio with an app called Droidstar. With this, access to the worldwide DMR network is possible.

My only reason for going on was to briefly go on the local CDARC net to give my apologies for tonight's FM net.

DMR is OK to have on in the background, but does not exactly "turn me on". It is OK for skeds, nets, and worldwide chats with a handheld, but is not really my "thing".

My network radio is an Inrico T320. It is ideal as a DMR handheld.

630m (472 kHz) WSPR RX

 For the first time this season I am on 630m (472 kHz) WSPR RX. 

As my son managed to cut my earth-electrode "antenna" in the ground whilst gardening and being "helpful", I am having to use the coax up to my 2m big-wheel with a ferrite rod ATU, much as in this photo of 10 years ago shows.

The noise level is S8 on the FT817ND's meter.

UPDATE 2118z:  unique stations spotted with the furthermost GM4SJB (692km). 

SAQ transmission Wednesday

M0NYW VLF converter
I am told by Jason M0NYW that there is a special transmission of the historic VLF alternator transmitter SAQ on 17.2 kHz CW. This is a good chance to test your VLF system. This TX is about 100 years old! Jason has made an excellent job of his VLF converter (see photo).

Local shop in the village - NOT amateur radio

 

This was our local shop a few days ago with my wife in the yellow jacket.

Late afternoon sky - NOT amateur radio

 

This was the sky on Sunday afternoon in our village. Today has been mostly showery - very November.
