Overnight on 630m WSPR

As usual, I went on 630m WSPR (10mW ERP, 20%) overnight. My own QRPP signal was spotted by 11 unique stations and I spotted 15 unique stations on RX. There seem to be a few more active stations on 630m WSPR.

Sunspots - Monday October 30th 2017

Solar flux is 76 and the sunspot number 23. A=4 and K=1.

10m FT8 RX

As usual, I am on 10m FT8 RX for the day. So far, 8 Russians with best DX R9CU (3878km). I presume these were F2 propagation. In addition some Gs and a PA which were either tropo or aircraft reflection. I am using the latest released version of WSPR-X V1.8.

QSY to 630m WSPR

I've left 10m FT8 and am now on 630m WSPR transceive (10mW ERP) until breakfast tomorrow.

CQWW SSB contest

There were a few South Americans coming through on 10m SSB earlier and I worked EF8R in the Canary Is whilst using my 5W on 10m SSB. To be honest, these days my voice is not up to SSB contests, so I returned to 10m FT8 digital .

10m FT8 RX

I have been using the latest formal release of WSJT-X (v1.8) in the last few minutes. Best DX is EA3KU (1265km).

UPDATE 1254z: VK6XN (14463km) is currently the best 10m FT8 RX DX. So far, 4 continents spotted on 10m FT8 today.

UPDATE 1605z: 5 South Americans now spotted on 10m FT8. 5 continents spotted on 10m FT8 today so far.

Sunspots - Sunday October 29th 2017

Solar flux is 76 today and the sunspot number 23.  A=6 and K=1.

WSJT-X V1.8 now properly released

For some time various release candidate versions have crept out, but V1.8 is now formally released. I have just got this for my Windows 10 shack PC.

See http://physics.princeton.edu/pulsar/k1jt/wsjtx.html

Be sure to get V1.8 and not V1.7.

4m (70MHz) allocations

It is some years since I last tried 4m using my homebrew transverter and a wire dipole in the loft. Since those days many more countries are on the band. I imagine working Es DX in the summer is quite fun on the band.  The IC7300 even has 4m coverage.

I am not up to date with which countries have 4m, but I seem to recall a CEPT move to allow national organisations like OFCOM to allocate (part of) 4m to amateurs.

With the lower VHF bands being less popular with commercial users (big antennas on portables and Es interference), the chances of more countries allocating 4m to amateurs must increase.

In the USA the FCC might even allocate the band - well, by the 22nd century!

QSY to 630m WSPR transceive (10mW ERP)

A few moments ago I QSYed from 10m FT8 RX to 630m WSPR transceive. My first transmission got spots from 4 unique stations even though the transverter crystal was still drifting. Encouraging. Best DX was F5WK (364km).

UPDATE 1954z: LA3EQ is active and has spotted me before this autumn. Let's hope he stops on until the middle of the night and spots me again. With the earth-electrode "antenna" my best DX on TX was over 1000km. It would be good to better this this season.

UPDATE 2045z: Now 6 unique stations have spotted me and I have spotted 12 unique stations so far this evening on 630m WSPR. EA5DOM was regularly spotted here on 630m WSPR earlier this season and was always a good signal with me, although I have not spotted him recently. Either he is using a different mode or a different band.
