8m QRP FT8 (Sunday)

My QRP FT8 has been on for about 2 hours. So far, no spots. 

UPDATE 1736z:  No spots all day.

UPDATE 1820z:  Scare!!  On 8m, there was no output on FT8. I feared the PA in the FT817ND had been damaged. I connected a 2m antenna and 10m antenna and tried FM. All was well thankfully. Later, I returned to 8m FT8 and all was well. I guess the PA had got too hot. Now QRT.

10m QRP WSPR (Sunday)

My 500mW 10m WSPR beacon has been on for about 90 minutes. It is now 1540z. So far this afternoon, 17 stations have spotted me (see table).

UPDATE 1735z:  20 unique stations have spotted me today.

Optical over the horizon

Before my 2013 stroke, I enjoyed 481 THz tests over the horizon. These days I am unable to do these tests. 

Chilling

This photo was taken in 2006 on Lake Annecy in France.  Looks like a copy of Practical Wireless in my hand. 

Sunday plans

The first thing I want to try is my FT-710AESS again. One possibility is the AESS only works if everything is connected and then the rig turned on. If this fails, a phone call to MLS will be needed. I really hope this is it. Does anybody know if, on later firmware, the fan only comes on when the rig is hot?

Other plans are 10m QRP WSPR TX with my 500mW beacon and 8m FT8.

Yaesu FT-710AESS first impressions

Yesterday, I fired up my Yaesu FT-710AESS for the first time. It is very highly rated on the Sherwood tests coming 4th. 

As a dedicated QRPer, it will be used mostly on its lowest power (5W), although I may run 10W PEP on SSB. It is capable of 100W on the HF bands. It does not cover 2m and 70cm, but does include 4m.  

Everything (I think) seems OK, although the AESS appears not to work, merely switching to the external loudspeaker irrespective of the degree of balance. 

The fan (which used to be on all the time in first versions) appears not to be on. I am not sure if this was changed to come on only when the rig is hot. I want to do a full reset, but want to talk with MLS first in case this loses me 5 MHz and 70 MHz bands.

I am hoping the AESS issue is "finger trouble", although I did everything as stated in the manual (I thought). If the reset does not fix the issue and I cannot find something simple that I am doing wrong, it will have to go back to MLS under warranty. Otherwise it is a good buy.

UPDATE 1546z:  I tried making sure the external LS was connected before turning the rig on, but sadly this did not change things. I have asked MLS about a reset and the fan. I hope the rig does not have to be returned under guarantee as otherwise it is a fine radio.

Sunspots - Sunday February 12th 2023

 Solar flux is 210 and the SSN 209.  A=11 and K=1.

PSKreporter issues?

Usually, I use PSKreporter to see who is spotting my 8m QRP FT8. A few moments ago (about 1315z) briefly a spot showed up of me from the USA and the Canaries. I have not seen these since. So I am puzzled. Did I reach there or not? 

UPDATE 1640z: Mystery solved:  it was reporting my 10m WSPR. No PSKreporter issue. So no, I did not reach the USA today on 8m FT8. Ah well, you win some, you lose some. There will be another day.

Digital modes and time synchronisation

Many digital modes need the PC clock to be accurate. To this end, many use online time servers for this purpose. 

For some time now I have not bothered and use Windows 10 to do the syncing. To do this you have to make sure that Windows 10 can synchronise. Once a day seems to be adequate, although I have habit (probably not necessary) of doing a re-sync when I enter the shack.

If you have Windows 10, this may be all you need.

Hare Park, Chippenham near Cambridge - NOT amateur radio

 

This is another view of Hare Park showing the lake. At this time of year the extensive gardens are open so the public can see the millions of snowdrops that carpet much of it.
