IC7300 fan questions (again)

Basically, these questions were asked a few weeks ago, but I did not get a decent reply. If you know the answer(s) please post them here or send me an email.

My basic questions are about the IC7300 fan noise. As a confirmed QRPer it is very unlikely high power would be used. Mostly 10W or less would be used if I bought one. It is by no means certain I shall buy one.

My questions are these:

1. Is the IC7300 fan noisy? 
2. If operating at well below maximum power does the fan run quieter?
3. Does the fan only operate when the rig gets hot?
4. Does the fan only operate on TX?

On the IC706, which I briefly owned, the fan was very annoying. I have seen mods to change the IC7300 fan to a quieter one, but I would be reluctant to do this on a radio still under guarantee. Running at way below maximum power, I may be unnecessarily worried.

If you can help, please let me know.

QRT

I went QRT at 2000z. Overnight I am not active on any bands RX or TX.

Big skies - NOT amateur radio

In East Anglia hills and mountains are hard to come by! What we do have are big skies. Norfolk and Suffolk have more hills than you might expect, but these tend to be gentle hills rarely over 100m ASL. We also have lots of medieval churches with round towers!

The photo was taken from a moving car about 1 mile from our home in Cambridgeshire.

Autumn apples - NOT amateur radio

The orchard in the garden next door is laden with apples. The photo shows a few windfalls in another garden.

Solar data

Early every month I take a look at the latest solar data. As yet, my source has not been updated with the summary for September.

We are approaching the next solar minimum so we can expect long periods when the sun will be spotless. This could well go on into 2021. The next minimum will probably be 2020. I also keep a watchful eye on predictions for cycle 25. The last forecast was expecting cycle 25 to be similar to cycle 24.

See http://www.solen.info/solar/

UPDATE 1552z: The data for September is now there. At the moment, the forecast is that we are already very close to the solar minimum. The next few months will give us a better idea. One of the graphs shows us already at solar minimum. Let's hope this is right.

More problems for the Chinese?

In a report today on Southgate News I see that New Zealand is trying to put a stop to the illegal import of unlicenced radios that can go outside amateur bands. This could impact people like Baofeng who sell cheap wideband radios. There is also a clamp-down in the USA.

10m FT8

For a change, I am on 10m FT8 (2.5W), mostly RX with the occasional CQ. So far, no spots of others and 1 spot of me from GM4WJA (624km). Not sure of the propagation mode.

UPDATE 1025z: No further 10m FT8 spots on RX or TX.

UPDATE 1107z: A surprise FT8 QSO (in answer to my CQ call) with CS7AOL (1457km). No other spots.

UPDATE 1505z: 5 stations in 4 countries spotted on 10m FT8 RX.

UPDATE 1542z: I am again calling CQ (2.5W). The impression I am getting is that transient E layer openings are still occurring, albeit less frequently than in the peak Es months, but there are fewer people on now: I guess they think 10m is "dead" and look elsewhere sadly.  At least with FT8 it concentrates activity and works with weak signals. As long as the station is there for 15 seconds, it gets spotted.

UPDATE 1907z: Several more Europeans spotted plus several South Americans (8). Sadly, no-one has spotted my CQs from outside Europe except EA8CYL (2990km) in the Canary Is off Africa.

Sunspots - Monday October 1st 2018

Overnight on MF WSPR

8 unique spots of my 10mW ERP 472kHz WSPR over night, with best DX a spot from PA3ABK (306km).
