Digital modes this morning

This morning I have been using digital modes JT65 and JT9-1.

I did see one station on JT9-1 on 10m but it did not decode, so I have been on 20m where I've had some success, albeit around Europe.  As well as using WSJTX for QSOs, I'm also monitoring who is copying me with PSK Reporter on JT65 and JT9-1 modes. So far, I have just been seen around Europe today.

So far, solid 5W QSOs with EA7AH (JT9-1) and IW4DBY (JT65) both on 20m.  Presently, I am monitoring 10m JT9-1 but no stations received here over lunchtime.

I may go back to 10m WSPR shortly.

472kHz WSPR "uniques"

472kHz unique stations reporting me this summer so far on WSPR.
My "scores" have now gone up to 16 unique station WSPR reports given and 14 unique station WSPR reports received so far this summer. The latest was Richard G4KPX on both 472kHz WSPR RX and TX.  He is a local (14km) and I thought he'd already seen me on 472kHz, but this must have been on 10m. Richard uses an indoor 472kHz loop on both RX and TX and 1mW ERP. There are some decent ranges here on both TX and RX.  GM4SLV must have a nice low noise RX set-up as he misses very little.

JT65 and JT9-1

Tomorrow, I may give these modes a better go. In recent days I have reverted to WSPR (which I can monitor in the lounge) but feel the urge for more 2-way QSOs, which is very hard on SSB and CW currently as a result of my stroke.  Hopefully my normal voice will gradually return.  At the moment speaking is very tiring as I get breathless. and forming words is hard going.   CW is also not so easy.  JT65 and JT9-1 are perhaps the best 2-way modes for me right now. They require limited keyboard skills which I can manage.

472kHz WSPR - early evening

Since returning from our younger son and family in Kent, I have turned on 472kHz WSPR both TX and RX. Just some of the regulars on. Otherwise pretty quiet this evening. These are the spots in the first 40 minutes or so.
Early evening on 472kHz WSPR

Largely non-radio day

Son and grandson outside their home.
Although I shall probably go on 472kHz WSPR shortly, today has been a day largely without radio: we went on a train day return to Canterbury to see our son Chris and family. We have done this now 3 times and get about 4 hours with them. It was good.

15th station seen on 472kHz WSPR

No new stations spotting me overnight but I did spot my 15th unique station this summer DJ0ABR (983km) which is a new distance record for me this summer.

472kHz WSPR - immediate success

Since QSYing down to 472kHz WSPR, the reports have been flooding in, even though ERP is less than 5mW.  These are the initial spots since going on to MF.  Note yet again the daylight spots from GM4SLV (896km) way up in Shetland. No totally new reporters yet, but maybe tonight?
UPDATE 1925z:   G8AGN has been spotted as the 14th unique station seen this summer at around -21/-22dB S/N.
14 unique 472kHz WSPR stations received this summer so far
UPDATE 2035z:   Currently 29 stations active on 472kHz WSPR. Hopeful of being spotted by new stations tonight.

10m WSPR - for a little longer still?

It has been very quiet now on 10m WSPR since 1328z when LA3ZA was last coming in here via Es. Apart from local G4KPX, the band has been very quiet on WSPR.  I even checked the gear was working as it seemed too quiet.

I shall stick with 10m until about 1830z, then QSY down to 472kHz again. Currently there are more active stations on 472kHz (22) than on 28MHz/10m (15). Of course these numbers can rapidly alter and http://wsprnet.org/drupal/wsprnet/activity only shows stations spotting in the last 10 minutes, so if you hit a quiet patch, you appear to disappear.

F2 will be hard to see with WSPR as there are so few active stations where they need to be - just 2 in the USA and 1 in South America only. Without stations at F2 ranges on WSPR, WSPR rather loses its point. No F2 seen here on WSPR today, but that may be down to an absence of WSPR stations rather than conditions.

Why do so many stay on 30m (68 active) or 20m (104 active)?  Operating on these bands teaches us very little indeed. Operating on the higher HF bands and 6m teaches us a lot about fleeting openings and propagation. In recent days there has been evidence of MS on 10m WSPR. It tells us a lot about 10m/6m GDX too.

See http://wsprnet.org/drupal/wsprnet/activity .

UPDATE 1606z:  The number of active 10m WSPR stations has now jumped to 22 with 7 in the USA.

UPDATE 1636z:  As it is so dead on 10m, I am going to QSY to 472kHz immediately.

UPDATE 1640z:  Now QSYed to 472kHz WSPR.

Hamspots - a useful resource

See http://hamspots.net/3bjt/ .

A little while back someone introduced me to Hamspots which is a sort of  filtered spotting system for digital modes. You can chose how many bands to monitor and the modes, Very useful to see JT65 and JT9-1 activity on, say, 20, 10 and 6m.

10m Es - GM4AOS

The latest station to be spotted on 10m WSPR is GM4OAS (653km) at -22dB S/N at 1314z using 5W. Apart from the GM, there has been nothing since SI9AM at 1212z. No Es and no F2. I am still on the lookout for real DX on 10m.
