Gs only on 10m and 6m WSPR

On 6m WSPR I have been spotted by G4MLA (53km) and on 10m WSPR just G0LRD (25km) spotting me. No F2 DX and no Es here all day on 10m and 6m.

New rigs?

At the moment I am happy with the rigs I have, so I can wait to replace rigs.

At the moment the IC7300 looks a favourite over the FT991, but a decent FT817 replacement at the right price might fit the bill. All decisions on future investments are predicated on the price being right. I want dealers to make a fair margin, but I do not like being ripped off.  On the IC7300, dealers are making a mint out of early adopters who want the rig at any price. Later, the IC7300 price will drop.

I am awaiting Dayton to see if Yaesu really does replace the workhorse FT817. I have my doubts. As you know, 5-10W is quite enough for me.

Sunspots and 10m - Sun May 8th 2016

Solar flux is 87 today. Sunspot number is 51 but K=7. The forecast for 10m propagation remains "poor". With very disturbed conditions it is unlikely 10m will be any good today, although Es may liven things up. I have been on 10m WSPR and 6m WSPR since before breakfast.

UPDATE 0858z:  Unsurprisingly, no spots so far today! Maybe I'll spot, or get spotted by, some locals?

UPDATE 1454zStill no spots at all on 10m WSPR and 6m WSPR. Dire.I may go on 472kHz WSPR tonight.

ICOM IC7300 first reviews

Steve G1KQH has brought to my attention the first reviews on eHam of the IC7300.

Because of the wide front end filters, some have reported front-end overload issues. Software/firmware updates will not fix this as it is an inherent issue with wide front-end filters: nearby BC or amateur stations can swamp the front end and the rig sensitivity nosedives. As long as the overload does not occur it is a fine rig. I can see no good reason why this rig should be any worse than others that use sub-octave filters rather than narrow bandpass filters for each amateur band. Such designs are common nowadays in front ends.

I think sensitivity starts to collapse if the rig sees more than 70mV in the front end. If you have a nearby 1kW station operating in the same band, you could have problems. You might also have problems with multiple very strong BC band stations.

Although without 2m and 70cms, the European version does have 4m, which is good. I still just prefer the IC7300 to the Yaesu FT991. The price needs to drop though!

Eham reviews point to an overload in the front end:

10m F2 DX

PU3WSF (10416km) has been spotted on WSPR 2 times in recent minutes. I shall stay on 10m WSPR a bit longer in the hope that my own signal will reach S.America before the band dies out. Good to see some F2 DX on the band. At this time of year it is possible some of these openings are a combination of Es and F2 further to the south. There has been Es right across Europe all day on 10m.

UPDATE 2135z:  Nothing on 10m WSPR for over an hour now. I am staying on the band overnight, but think we have now seen the end of F2 and Es for the day.

FT817 replacement announcement?

If the rumours are to be believed, this month we may get an announcement at Dayton on a replacement to the FT817. Of course, it is entirely possible we will not!

In my view, Yaesu have "missed the boat" and should have launched such a product on the approach to the sunspot maximum rather than on the downward slope.Yaesu certainly need some "must have" features if they are to be as successful as with the FT817.

Plentiful Es on 10m

It will soon be time to get back on 6m as the Es season is really with us now. There is daily Es on 10m and I expect there will be Es openings on 6m too. I have not seen any F2 DX on 10m WSPR for a little while. It will be interesting to see if 10m opens to the USA this autumn. I think it will on a few occasions and certainly far less often than last year. Any USA 10m spots this autumn will be a bonus.

Stroke update - NOT amateur radio

2.5 years after my cerebellum bleed, I am still suffering. The worst are the poor speech, the profound exhaustion I suffer after most mental or physical exertion and feeling drunk all of my waking hours. To others I look fine. This is part of my frustration: everyone thinks I am fully back to normal, whereas I know different. It is very very hard to accept.
UPDATE 1528z: This afternoon I creosoted (actually a substitute these days) our garden shed. In the past this would have been a quick and easy job, but now it really exhausts me. There is still one side to do tomorrow as well as putting up a different bird box for next season.

Sunspots and 10m - Sat May 7th 2016

I have been on 10m WSPR since about 0715z (2W TX 20%, RX 80%).

Solar flux 89 today and sunspot number 56 (K=2). The 10m propagation forecast remains "poor". although withe the Es season we can expect some short-skip in 10m most days.

UPDATE 0908z:  Plenty of Es short-skip on 10m WSPR already, plus locals.  Today could be quite productive on 10m WSPR by Es. It would be good to see some N-S F2 propagation on the band too.
